JPMorgan Athena | NYC and London | Full Time | ONSITE

I expect you’ve heard of JPMorgan at some point, but probably aren’t familiar with Athena. We’re the bank’s in-house platform for cross-asset pricing, risk management, trade management, e-trading, etc.. There’s a core division (cleverly named “Athena Core”) of about 150 engineers which builds a platform and development libraries that are then used by over 5,000 developers throughout the bank.

The Core Analytics team currently has 8 members and is responsible for extending Athena to research teams and for reducing the gap between research and production use. To give a simplified example, our typical customer is a quant who might be attempting to create a new pricing model. Core Analytics would help him access relevant data sets, explore that data with a library of common statistical functions to, verify the new model with a back-testing framework, and then finally publish the model to production.

Python and C++ are the primary languages, but we’re open to considering exceptional developers with any background. Finance experience is certainly not required. Our two main offices are in NYC and London; we also have satellites in Tel Aviv, Tokyo, and Singapore.

Email Christine.h.ko@jpmchase.com to apply.

ONSITE in NYC, SF and many other locations | Engineers, Designers, Product Manager | VISA and RELOCATION assistance

Pivotal Labs is a division of Pivotal Inc.

Labs helps clients to become better at development. For engineering we are religiously lean and agile -- in practice that means we pair program and TDD every line of code from the outside. Our product managers are fantastic at keeping products sharply focused, our designers are masters from users to pixels. We have a growing data science practice, and some engagements include all four roles. If you want to work in product instead of consulting, we also have dozens of teams working on Cloud Foundry, Big Data Suite, Spring and I probably forgot some cool stuff. Or you can rotate: I had a 7-month secondment to Cloud Foundry which was awesome.

Our NYC office is growing fast to meet exploding demand for Labs, Cloud Foundry and Big Data Suite.

We are also hiring in all our offices, including new offices: SF, Palo Alto, Los Angeles, Seattle, Boulder, Denver, Chicago, Boston, Washington DC, Toronto, London, Dublin, Berlin, Tokyo and Sydney.

We provide visa and relocation assistance. In the NYC office we have about 15 people from overseas, including Australians like me.

At the office we have free breakfast, weekly tech talks, good benefits and competitive pay. Ping pong is not mandatory, but it's popular. I think west-coast ping pong is harder to beat, but east-coast style is more entertaining to watch. The beer fridge has more IPA than I prefer but I guess that's life in paradise.

Frankly this is the best job I've ever had -- I've learnt more here than anywhere else. Everyone is smart and fun to work with.

We look for aptitude over APIs. It doesn't matter wether your resumé says PHP or PhD: if you're smart, know some stuff and have empathy, I and my peers want to work with you.

You can apply through our website: http://pivotal.io/careers, but if you email me -- jchester@pivotal.io -- I can take advantage of our generous referral program and answer any private questions you might have.

Distilled (www.distilled.net) is hiring in London (UK), New York City (NYC) and Seattle WA - all permanent, full-time roles.

We have a whole host of open positions: https://www.distilled.net/jobs/

We recently had an all-hands email thread where the whole team discussed what brought them to Distilled, and why they are still here. It got many great replies (including a number talking about how people's friends had typically had 2-3 jobs in the time they'd been with us), but this one stood out:

"A combination of an informal environment, freedom, and high expectations - I wanted a place where I could be myself and grow doing/learning things that I was passionate about, while having lots of smart people around me to collaborate with in doing so. I came from a huge, strictly regimented and siloed company, and was fed up with being told "that's a great idea, but it's not your job", and Distilled seemed to be the polar opposite."

Ontoit (www.ontoit.io) is hiring in London! careers@ontoit.io

Ontoit is a technology startup founded and run by graduates from the University of Cambridge. We work on integrating large datasets into knowledge ontologies using machine-learning techniques and performing parallelised semantic search on big data. The end result of using Ontoit search engine is that meaningful relationships can be inferred between pieces of information. These relationships can be used to perform explicit semantic search through large amounts of data. The Ontoit search engine will assist industries in a variety of fields to find information and explore ideas in an integrative manner. In order to create the proposed search engine, we intend to combine five distinct fields in computer science: ontology engineering, machine learning, natural language processing, semantic search and distributed computing.

Ontoit will first focus on developing one application for the movie industry. Our first product will be a semantic search engine to traverse the corpus of movie information on the internet.

Here at Ontoit, we develop our entire backend in one programming language, Java. Spring framework forms the backbone of our web services. We develop knowledge representations using stacks of graph databases and technologies. Natural sentence queries are parsed through an engine built using Stanford CoreNLP. Computations are distributed to a cluster developed using Apache Storm. Data crunches for Machine Learning models are parallelised using Spark. We store our data in scalable, NoSQL Cassandra.

Our system architecture is designed in great detail with a high degree of modularity and scalability.

Ontoit is currently recruiting for multiple positions: Team Lead, Core Developer, NLP Developer, QA Developer. All positions are full time and we offer competitive salary + significant amount of equity.

Our elegant, real-time dashboards solve an important, tricky problem for thousands of paying subscribers, by taking the complexity out of connecting to their data and making that data simple for everyone to interpret at a glance. As a result, our customers unlock data they didn't know they had, connect people and join up projects, and make better decisions faster.

We are looking for a senior front-end developer who dreams in futures and promises, is excited about tail-call optimisation in ES6, uses TDD consistently, and builds super-usable single-page applications. Any React knowledge is a plus but we are happy for you to learn with us. See our jobs page for details: https://www.geckoboard.com/careers/

We’re constantly striving to ensure that we offer the most encouraging, supportive and efficient environment possible. We want everyone on the team to participate in making our architectural decisions. The whole team is involved in prioritising and evaluating our work and we regularly program in pairs to share knowledge, promote collaboration, and improve code quality.

Flexible working hours and the ability to regularly work from home let you work in a way that fits you and your family, and we have generous maternity and paternity leave policies. We see our contractual obligation to offer 25 days' paid holiday as a /lower/ bound for everyone in the organisation, not a limit. We actively contribute to personal and professional development and have a minimum budget allowance to be spent on courses, conferences, and books. We also run fortnightly "innovation days", where everyone has complete freedom to work on anything that interests them, from contributing to open-source projects, learning a new skill, or improving our internal tools and processes.

MUBI :: San Francisco, CA :: Software Engineer

MUBI is hiring software engineers to start growing our San Francisco team. We are a VoD company with a focus on bringing the best films to our customers around the globe. What sets us apart is true editorial credibility in the film world, and a strategy building social traction with a cinephile audience before putting Studio content deals in place. That time has now come. We are at an inflection point where we will massively scale the subscriber base. If you have been looking around the Valley and concerned that valuations are out of control and investors are chasing too many flimsy business models, then you should take a look at what we're doing.

The product is a streaming service and social network currently available on the web, iOS, Android, Amazon Fire TV, PlayStation, Samsung Smart TVs, and several more on the way. It is build primarily of Ruby, Rails, Backbone + Marionette, and the usual client-side frameworks. We are heavily invested in Chef for configuration management, both at Engine Yard where we host our main applications, and also for newer infrastructure such as our custom-built CDN that we are tuning to deliver a better QoS than off-the-shelf vendors can provide.

The position is for the second engineer to be sitting next to me (Co-Founder & CTO) and our Head of Product in our San Francisco offices. Although we were founded in Palo Alto, currently the CEO and bulk of our team is based in London due to the UK being our primary growth market. We are now looking to move the product and engineering center of gravity to San Francisco in a run up to make the US a primary market in 2016 and beyond. You would be #10 software engineer overall, and will play a strong role in defining the architecture of our application. Strong ruby and rails skills are ideal, though this can be substituted by strong web and backend development skills in similar languages and architectures. VoD and client-side video app development are a bonus but not required. You will have significant opportunity to define your own position and work on any area of our technology where you can add value.

If you are interested please contact me by email, which can be found on my MUBI profile at https://mubi.com/users/2

Firefly Learning | Developers | London UK | ONSITE

Imagine you could save every teacher in a school one hour a week. Instead of an hour of drudgery, they could be preparing their lessons, teaching or actually having a life outside the classroom. At Firefly, you can help do exactly that.

Firefly is a learning platform used by hundreds of schools worldwide to create, share and learn. We combine easy content creation with deep school integration to make a useful tool for class work, homework, and coursework. We’re self funded and doubling yearly. As an established company serving many customers and integrating with a variety of other services, we’re continually learning how apply best practices to existing code, whilst still deploying new features and bug fixes for teachers and students every two weeks. We're currently focusing on getting better at separating of concerns and building up an automated testing suite. We’re also improving the speed and reliability of our infrastructure, and trying new technologies to keep current (e.g. Swift and React).

We looking for four main strengths in you:

skill: your colleagues would say you get things done. You work to a high standard, and know about and apply appropriate best practices in your work. You are at home with improving and extending existing code as well as new development.

desire to learn: despite (or perhaps because of) you being good at what you do, you want to get better. You seek out best practices, new ideas, honest feedback, and unknown areas of code, in order to know more and work better.

understanding: our product team is great but not infallible. You’ll be happy to challenge and clarify product decisions with our users’ best interests at heart. Similarly, our QA team is meticulous but not your babysitter. You’ll be handing something polished to QA, not throwing the first thing that compiles over the wall. Overall, everyone at Firefly shares responsibility for the product making sense and being of high quality.

clear communication: We have a lightweight process, so most days, other than a morning standup meeting to share what’s going on and what’s planned, you’ll be responsible for your time. This also means that, when there are issues, you need to inform the right people, explain what’s going wrong, and help get things resolved and moving forward again. Speaking of process, we have a design team who handle HTML and CSS, a product and UX team who produce clear specifications, a QA team to help us build things well, and a two-week sprint cycle for getting things done. Other than that, we’re pretty small-a agile and are happy to try things out to see what helps.

In terms of experience, we need you to be comfortable with iOS or a web platform. Our server-side code is written in C# and our web front end has some Javascript, so you’ll need to know these or be able to pick them up. We work as generalists, so experience of any of the following would be a positive: Android, Windows Phone, shell scripting, infrastructure automation, databases, particularly SQL Server, building API integrations.

We offer competitive salaries dependent on experience, a generous bonus scheme, flexible training budget, brown bag talks and a Kaizen day for self-improvement and experimentation every fortnight. So, if you’ve got an interest in education and a desire to learn your craft alongside others making the same journey, we want to hear from you. Drop me an e-mail (robin at fireflylearning.com) or apply on our website – http://fireflylearning.com/join-our-team/jobs/developer
