#1 of 49JPMorgan 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.

Geckoboard is a successful, growing 25-person B2B SaaS startup based in East London. Our elegant real-time dashboards solve a tricky, important problem for thousands of paying subscribers, by taking the complexity out of connecting to their data and making that information 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 front-end developer who is excited about tail-call optimisation in ES6, uses TDD consistently or wants to learn to do so, and builds super-usable single-page applications. Any React knowledge is a plus but we are happy for you to learn with us.
We are also looking for an experienced and highly technical QA Engineer. As our first QA hire, you'll have the opportunity to decide on the approach and tools that fit Geckoboard best. You will identify where our QA process is currently lacking, while making sure that we can continue deploying changes to the product several times a day.
Please 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.
We don't just pay lip service to work-life balance, we actively and strongly encourage it. 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.

We're hiring for a variety of roles -- started the year at 128, over 200 now, and hope to end around 256. This is a perfect time to join -- product market fit is established, but there's a lot of great engineering, product, sales, and support work to be done. We've publicly said we're profitable and on track for long term independent success.
You may wish to check out our blog to see the kinds of engineering work we do. (https://blog.cloudflare.com/).

We're always hiring for operations/SRE, sales, general systems engineering (mostly in Go, nginx, and network, as well as DNS at scale), and web development.
Specific roles we're keen to hire include:

1) Billing engineer -- someone to take the lead as we build a new billing system.
2) Great front-end engineers -- building new UI/UX to expose controls and data to customers is an increasing portion of what we do

#46 of 49OpenSignal - London, UK (Full time, permanent) At OpenSignal we're using mobile apps to tap into the smart phones we're all carrying around with us to build up global crowdsourced sensor networks. Our first sensor network is for wireless signal  where we are building a global database on the coverage and performance of wireless networks (both mobile + WiFi) on a scale that has never before been possible. Our second sensor network is WeatherSignal , which uses the barometers, thermometers and hygrometers on smart phones to crowdsource weather data and we have already published a scientific paper  showing the potential of this approach. Our third sensor network is WifiMapper  which leverages sensors and the community to build the best free Wifi database in the world.
If the concept of crowdsourced sensor networks appeals to you too then please get in touch. We are hiring for all manner of different roles right now (Android, Full-stack, Backend (Python), Frontend, UX/UI & Data Science(R, Pandas, Numpy, Spark)) but most of all we are just looking for smart, like minded people rather than people with specific, existing skills. We raised our $4 million series A  from Qualcomm Ventures, O'Reilly Alphatech Ventures & Passion Capital and we are growing fast.

#47 of 49Pivotal | ONSITE SF, NYC, Palo Alto and many, many locations worldwide | Engineers, Designers, Product Managers, Data Scientists | Visa and relocation assistance
First things first. We look for aptitude over APIs. It doesn't matter whether your résumé says PHP or PhD: if you're smart, know some stuff and have empathy, we want to work with you.
Pivotal's goal is to change the way the world makes software and we kinda sorta really mean it. We're broken into three basic divisions: Pivotal Labs (yes, that Pivotal Labs), Pivotal Cloud Foundry and Pivotal Big Data. Rotations between divisions, temporarily or permanently, are possible.
We have offices in San Francisco, New York City, Santa Monica, Palo Alto, Seattle, Boulder, Denver, Chicago, Boston, Washington DC, Toronto, London, Dublin, Tokyo and Sydney. We will soon be opening an office in Berlin as well, with more to come. Relocations, temporarily or permanently, are possible.
Each of the three divisions has a constantly evolving and deliberately cross-pollinated culture. We are constantly thinking about how we work and how we can work more sensibly, effectively and enjoyably.
-- Pivotal Labs, from which the company draws its name and cultural seed, 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.
-- Cloud Foundry solves application deployment and management. We're the main contributors to CF. We're expanding what is the leading opensource PaaS and our distribution has the fastest-growing sales of any opensource product ever. It's also the only PaaS I'd personally bet a company on -- except for integrated upstream code, every line is pair programmed and TDD'd. We dogfood the cutting edge of the technology on our own commercial public cloud (Pivotal Web Services). It works because we took the XP and Lean DNA of Pivotal Labs and scaled it up to build the best cloud platform bar none.
-- Big Data is home to a fleet of battled-hardened products that we have been progressively open sourcing. Greenplum Database tackles some of the largest datasets in the world with the comfort and familarity of PostgreSQL. Apache HAWQ (incubating) brings Greenplum's distributed query planner to Hadoop. Gemfire, which we donated as Apache Geode (incubating), is an in-memory distributed grid with years of high performance in high-stakes systems.
At our offices 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.
We provide visa and relocation assistance. In the NYC office we have about 15 people from overseas, including Australians like me.
You can apply through our website: http://pivotal.io/careers. You can also email me at firstname.lastname@example.org to answer any questions you might have and potentially help me score one of our generous referral bonuses.

William Hill are hiring:

For our Leeds City Centre and London Shoreditch offices.
Whilst we have a very well-established high street presence and brand (over 2500 stores, founded in 1934), this accounts for only half of our business - the rest coming from our online presence. We're seeking to differentiate ourselves in the industry through our speed to market, agility, and our ability to innovate.
There's a massive culture shift underway and we're looking as much for techies as well as people with the vision to modernise how technology is delivered and works.
Feel free to send me any questions and I'll put you in touch with the right people.
