#4 of 62Time Inc / Seattle, New York, Bangalore, London / Full Time, Onsite
Time Inc operates some of the most recognizable brands in the world. Time, Sports Illustrated, People, Entertainment Weekly, In Style, Southern Living, and many others. We are (finally) building out a world class engineering team to partner with our brands to extend their reach.
We've brought in strong technology leadership from the likes of Amazon, Netflix, and Microsoft.
I've got positions on the following engineering teams; DevOps (SEA, NYC, LON, BLR), Digital Asset Management (SEA, NYC, BLR), Branded Web Properties (NYC, BLR), Editorial Tools (NYC, BLR), Native/Mobile Applications (NYC, SEA).
We are looking for senior engineers and engineering managers with strong engineering fundamentals. We are just getting off the ground, so are looking for people comfortable working in environments with many rough edges.
@radeksimko is one of my team members in the UK and is doing great work on our DevOps effort. He recently became a committer on Terraform. He represents the type of engineer I'm looking for.
Please reach out to me directly if you are interested in learning more. Email in profile.
#5 of 62Distilled (www.distilled.net) is hiring in London, 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/
In particular, we would very much like to talk to digital marketing / SEO consultants in any of our cities.
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."

Engaging content is the future of online monetization, and we're building the intelligent infrastructure for deploying revenue-generating content.

This scale impacts every engineering decision we make, and we're looking to build a company with people excited by the challenges it poses.
You'll want to have interests or experience in some of the following:
* Working extensively in functional languages (we mostly use Scala, with Akka, Spray, Scalaz; some Haskell).
* Building large-scale distributed systems (we run a microservices architecture on AWS)
* Designing and implementing proprietary machine learning models and real-time personalized recommendation systems
* Rapidly designing and building front-end products (HTML/CSS, React, etc.)

#34 of 62San Francisco, LA, Chattanooga, London, Mumba - Full-time / Onsite OpenTable
We've got a ton of job openings; mostly in the Node.js space, but also for .Net engineers, Devops, front-end engineers, DBAs, non-node JS devs. Pretty much everyone.
I joined 4 or 5 months back and am very happy here. SF Office has a great nerdy culture; lots of tech talks, hosted meetups, engineer-friendly policies (sane WFH, good vacation, 20% policy, 'boyscouting' (fixing code unrelated to what you're working on) is encouraged). I very much enjoy working here, and I think most engineers would too.

#61 of 62Firefly 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.
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
#62 of 62Codurance is hiring Software Craftsman ONSITE in London, UK.
You consider yourself a software crafter. You care about and are proud of the code you write. You care about doing meaningful work and providing value to your clients or employer via well-crafted code. For you, writing code is not just a job but also a passion.
Test-Driven Development is second nature to you and that's how you write code. You don't use "lack of time" as an excuse to do a mediocre job, and fully understand the long-term costs and benefits of hacking a project together. You prefer to work in small increments, trying things out and iterating rapidly, tightening the feedback loop as much as possible.
You are a team player. You understand that software lives on long after it is first delivered, and that many different people will contribute to it over its lifetime. You enjoy working with other people, including other coders but also designers, business analysts, testers and anyone else working on the same project. You enjoy frequent collaboration, including pair-programming.
As a passionate developer, you spend a considerable amount of time outside working hours investing in your craft, learning new technologies and practicing different techniques and approaches. You create for creation's sake, building pet projects or contributing to open-source development. You don't do this because a client or employer asks you to; you do it because you want to.
As part of the learning process, you consider it important to share what you know with others. This might take the form of a blog, some code on GitHub, attendance at community events or something totally different. You also consider it your responsibility to help your fellow colleagues; perhaps this manifests itself as formal knowledge-sharing sessions in the workplace, but just as likely, it's simply coaching as and when it's necessary.
You understand that languages and frameworks are just tools. You choose the best tools for the job without being religious about it. The majority of books and articles you read are the ones that makes you a better developer and not a specialist in a specific framework. At the same time, you are extremely proficient with at least one or two programming languages and the tools around them, including testing frameworks, wiring and dependency injection mechanisms, user interface libraries and development environments.
You understand and embrace Agile processes, and are able to help other people to understand and adopt them. You are able to work closely with clients and product owners and help them to refine requirements and plan the work to be done.
You are proud to be a developer and want to remain a developer. You believe in emergent and collaborative architecture and design; you use your knowledge of SOLID principles, the Four Elements of Simple Design, and Domain-Driven Design to design applications that reflect the business domain.
If you believe you can meet the bar set, we are definitely interested in hearing from you.
