Development of digital products is central to the future of the Guardian. We build the products that showcase our diverse and important journalism. We create the tools that the journalists and editors use to write their stories securely, anywhere from London to Syria. We write the APIs and services that allow those stories to be distributed across the globe. We write the products and interfaces that show off and monetise that content to its maximum potential.

We mostly program in Scala and Javascript, but we use the best tool that fits the problem. We have hacks in the wild in all manner of languages. Our infrastructure lives on AWS and our own OpenStack private cloud. We encourage product teams to implement, manage and support their own stack. We do our coding in public. Sadly, the same can be said of our karaoke.

You’re a passionate, intelligent human being who loves technology. You might love the news, or you might want to reinvent it. You like inspiring the people you work with and being inspired by them in return. You have experience of getting stuff done. You are a talented Engineer who is, or will be, an expert in their chosen field and has a strong interest in all software engineering disciplines.

Further information can be found on our Developer Blog: http://developers.theguardian.com/join-the-team.html

Longshot Systems | Senior Software Engineer | Marylebone, London, UK | ONSITE | Full time | £50k-£?k

Longshot Systems is a sports analytics company that provides software to assist professional gamblers to bet profitably. We need highly skilled engineers to take on all aspects of our stack. We have a distributed, event based system processing thousands of signals per second with very tight latency requirements. Our clients trade millions of pounds using our technology. We use go, java, postgres, rabbitMQ and various other technologies for the core systems.

You would have at least a few years of experience in either Go or another general systems language to a high professional standard and have been involved with handling money, distributed systems, testing, maintaining and perhaps some sysadmin skills. You'd join and help shape the architectural direction at the company and get involved in all areas of the production codebase. Knowledge of sports or betting not required.

We have an office dog, Minos, who is rather cheeky. If you need a pic to help in your decision making process, we can provide.

Our customary office hours are week days from 10 til 6. If that's not good for you, let us know, we're flexible.

Unfortunately we can't support visa applications at this time. If you would like to apply or request further information, email me at jobs@longshotsystems.co.uk

Permutive (YC S14) | London, UK | ONSITE | http://permutive.com

We're building the infrastructure for event-based personalization.

Our API lets you collect, retrieve, and query your users' behavior in realtime. It's the easiest way to integrate behavioral data into your product: we handle the collection of every user's interaction and provide a flexible query layer to react in realtime to their events.

We're looking for full-stack engineers to design and develop our core product. You'll be responsible for tackling and owning hard technical problems end-to-end. You should have experience and interests in some of the following:

* Working extensively in functional languages: we use Haskell, Scala (with scalaz), and Elm

* Building large-scale distributed systems: we run a stream data pipeline on AWS with Kinesis, EC2, DynamoDB, Postgres, S3, and friends

* Data engineering, particularly stream processing and applied ML, e.g. recommender systems for personalization

* Developing and scaling APIs and frontend products

We're an early-stage VC-backed startup with some of the top investors in London and Silicon Valley, including Y Combinator. Because we're a small team, you'll play a central role in everything — from product to company culture. We offer competitive salaries, equity, and bad jokes.

If you're interested, email us at jobs@permutive.com with your CV and anything else you think would be important for us to know!

We are looking for people at all levels of experience and are hiring for mindset rather than skill set so if you are interested in working on a mature, agile team please do get in touch.

Send your CV to james.maggs@... and I'll get back to you asap.

Skyscanner | London, Barcelona, Edinburgh, Budapest, Sofia | ONSITE, VISA | full-time

We're one of the biggest travel metasearch enginees in the world by traffic... and we want to x10 that :)

Hiring distributed systems engineers, full stack engineers and iOS & Android engieners. We are hiring to all our European offices - London and Barcelona being the 2 newest ones, with the most fresh buzz right now.

Specifically we're looking for people interested in working on large scale personalization challenges: how do we turn data we have of 50M monthly users' search habits into new products, or adopt our web site and apps to "just work" for any type of person. For example a busy traveller with less price sensitivity will want to see a different set of default results then a backpacker who is looking for the cheapest flights hitting multiple cities.

We've recently opened a Barcelona and London office - I'm one of the first engineers in London, and there is incredible energy across the company. We are set out to be the #1 flight search engine in the world: from the UK through US, all the way to Asia.

We're one of the very few unicorn companies HQ'd in Europe who are profitable - and have been so for the past 7 years. Recently we've had the director of Amazon S3, Bryan Dove join us as our VP engineering - in London you would be working closely with him (as I already am).

You can apply at http://www.skyscanner.net/jobs/ - or ping me at gergely (dot) orosz (at) skyscanner.net for a referral.

On a personal note I love the company's culture of "ask for forgiveness, not permission". Engineers make a LOT of decisions, so your ideas make it into production quite easily. This would be typical for a startup... but for companies this size it was a breath of fresh air to me. Any questions you might have, please email me and I'll be happy to answer.

Pivotal | ONSITE SF, NYC, Palo Alto and many, many locations worldwide | Engineers, Designers, Product Managers, Pre/Post-Sales Engineers, Ops and others | Visa & relocation for right candidate

First things first. We look for aptitude over APIs. It doesn't matter whether your resumé 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. Right now we are particularly trying to grow in Labs and Cloud Foundry.

-- 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.

-- Cloud Foundry solves application deployment and management. We're the main contributors to the Cloud Foundry project. We're constantly improving the leading opensource PaaS -- 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.

-- Generally

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 can 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 jchester+hn@pivotal.io to answer any questions you might have and potentially help me score one of our generous referral bonuses.

For what it's worth, I'm just an engineer, so my replies might not be immediate. I hope that's OK.

CloudFlare https://www.cloudflare.com/ | San Francisco, CA; London, UK; Singapore, SG; Urbana-Champaign, IL | VISA, ONSITE

CloudFlare is building a better Internet -- performance and security optimization at the edge. Our long term goal is to give every site the same performance, security, and reliability that major sites like Google and Facebook accomplish, without any specialized network hardware or complicated administration. We enhance millions of sites, including this one. We're hiring for a variety of roles -- started 2015 at 128, ended around 220, doubling again in 2016. 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/).

https://www.cloudflare.com/join-our-team has a listing of positions.

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:

0) Great operations/SRE staff: operating our system at scale (80+ datacenters around the world, 24x7 coverage, >4 million sites) requires highly competent, hard-working, and communicative engineers.

1) Product designer(s) -- we're looking for great talent to help build UX for new products, and to improve the interface and user experience of our existing products. We have a range of customers, from consumers with a single blog all the way through some of the largest sites on the Internet, and designing interfaces which work well for all of these users is a big challenge -- are you up to it?

2) Great front-end engineers -- building new UI/UX to expose controls and data to customers is an increasing portion of what we do. Our current front-end stack is Backbone + Marionette with Browserify and Sass. Our new projects are using React + Redux + Babel + css-modules, and generally adopting Higher Order Components. We're also starting the process of re-imagining our main WWW Front-end stack with a migration to Redux.

3) Systems Engineer -- looking for people to help serve even more traffic, build infrastructure for security and robustness, and contribute back to open source projects. We make extensive use of nginx, lua/luajit, and ssl-at-scale.

4) "Prototyping engineers" -- people who want to prototype things in go (backend) through js frontend. We're adding a lot of new products in 2016, and people who love building the first prototype and pilot versions of these products make everything faster.

(Also -- We're particularly interested in people with Mandarin experience; we have a joint venture with Baidu, and want to make the experience for both Chinese Internet users and Chinese sites abroad as great as it can be.)

If you're interested, please apply through the https://www.cloudflare.com/join-our-team link
