Online Programmer (Back-end) – Rainbow Six Siege

Full-time - REF20155A

Job description

As an online programmer, you'll be at the heart of building a solid back-end that supports Rainbow Six and its millions of players.

Within a team of around 10 programmers dedicated to creating, debugging, maintaining, and improving Rainbow Six's services on both the server and client sides, you’ll help ensure the game's stability and quality of service with a DevOps and live ops mindset.

Rainbow Six Siege is a constantly evolving game as a service, a competitive, esports-oriented 5v5 PVP shooter. Over the last 6 years, we have continuously added new content while simultaneously enhancing our technical and data foundations.

As a team, we firmly believe:

  • In a sustainable work rhythm and a healthy and inclusive environment
  • In iterative development and delivering value to players quickly (we ship live every 2 weeks );
  • That nothing is off-limits, and it’s possible (and encouraged) to deliver major technical improvements in small increments
  • That this philosophy enables us to deliver a better quality game for our players.

Surrounded by colleagues specialized in delivering core tech, throughout your onboarding - and beyond - you'll have the support of a host of experts who will help you develop and refine your skills while collectively elevating the quality and vision of the game.


What you’ll do

In a group that embraces iterative development, takes an open approach to design, and values feedback, you'll:

  • Ensure performance at scale. You’ll transition Rainbow Six Siege away from its legacy back-end and into a new microservices-based one, developed in Go and running on Kubernetes – all to support several million daily active users, playing 24/7 from all around the world, together on 7 platforms.
  • Support the development of online services and features. You’ll acquire an in-depth understanding of existing features, plus suggest and develop improvements. (We oversee player progression, economy, matchmaking, cheat prevention, and social networking.)
  • Offer technical recommendations. You’ll equip game designers with the means to achieve their vision and help them refine it.
  • Provide continuous integration/delivery. You'll orchestrate frequent, seamless upgrades of back-end code across all environments (including production), putting your work into the hands of gamers as quickly as possible.
  • See to reliability and observability. You'll minimize downtime for players through A/B testing and failure recovery; evaluate your code using metrics; and build dashboards to measure our quality of service.
  • Continue to improve Siege. (We're all about providing the best online experience for our players, after all.)
  • Collaborate with an array of people daily. You'll work closely with a variety of different cells within Rainbow Six Siege, external departments, as well as several internal production and support teams.
  • Stay on top of best practices. You'll keep an eye on DevOps and technological advances (especially the next generation of consoles).
  • Enhance your skills. You’ll interact with your client-side colleagues to develop your full-stack capabilities. (By the way, as a team member, you'll have the opportunity to change cells and touch on a variety of topics aligned with your interests.)


What you bring

  • Experience with back-end services and in a DevOps environment (or other relevant experience)
  • Proficiency in Go
  • Experience with Kubernetes and Docker
  • Requirement analysis skills
  • Open-mindedness: you’re receptive to new ideas and perspectives
  • The capacity to balance short-term priorities with long-term goals
  • A degree in Computer Science or Software Engineering (or related training)
  • A collaborative spirit + the ability to communicate within a large team spread across two continents

Just a heads up: If you require a work permit, your eligibility may depend on your education and years of relevant work experience, as required by the government.
