Today we are 1,000 people, generating $1b+ in annual revenue, profitably. Our games and apps have passed 7 billion downloads and reach 200 million+ active users every month, making Voodoo the #3 mobile publisher worldwide in downloads, after Google and Meta. We were backed by Goldman Sachs, Tencent and GBL along the way.\nThis position is Paris-based, with relocation support available.\nTeam\nFor this position, you will be an integral part of a newly established internal studio, a dynamic and focused team dedicated to one of our most promising prototype in scale. This studio is specifically chartered to improve this high-potential game up to the successful and market-ready title it is meant to become.\nYou will be part of the team building Draft Showdown, a turn-based multiplayer game, working alongside its client engineers and game designers as a full member of the game team. You will be part of a small group owning the backend that this game needs as its requirements become more specific and demanding.\nYou’ll also be plugged into Voodoo's shared gaming backend platform - the same architecture and patterns that power titles like Mob Control and Block Jam 3D - building on it and contributing back, in close collaboration with the wider backend team. You get the focus and ownership of a dedicated game engineer with the leverage and support of a battle-tested platform behind you.\nThis is a pivotal hire: Draft Showdown is moving towards competitive multiplayer, which means moving game logic from the client to the server. They are also implementing cheat detection safeguards to the game.\nYou will be central to that transition.\nRole\nYou will design and build the server-side foundation that takes Draft Showdown from a client-authoritative game to a competitive, server-validated one. The current game computes everything on the device - progression, economy, and match outcomes alike, which won't hold up for competitive PvP. Your job is to change that.\nWorking closely with client developers and game designers from feature design through delivery, validation and iteration, you will:\nBuild server-side validation for the metagame - currency, card upgrades, chest opens, and progression - staged by risk, replicating economy and reward logic on the server.\n\nMove toward server authority for competitive features, where game state lives in one place and can be trusted.\n\nImplement and improve matchmaking and cheat detection safeguards for a Deterministic lockstep PvP architecture\n\nDesign APIs and player-state management that the Unity client integrates against, and help shape how client and server split responsibilities.\n\nThe responsibilities are cross-functional, ranging from infrastructure, API design & coding all the way to client-side integration (we are using Golang).\nTo succeed in this role, you will need to have passion for everything you do. You love to write code that scales to millions of users, are skilled at requirements gathering, champion new tech initiatives & leverage existing solutions.\nProfile\n5+ years of backend development experience\n\nStrong knowledge of computer science fundamentals\n\nExtreme fluency in Golang (at least 1 year in a professional environment)\n\nMastery of SQL and NoSQL\n\nBackground in high-scale systems\n\nUnderstanding of Unix-like environments\n\nAI-first mindset: Comfortable using AI daily and building custom agents or reusable automations to speed up your work\n\nExperience working in cross-functional agile teams\n\nStrong analytical skills with a track record of solving complex problems related to scalability, performance, and integration in high-stakes environments.\n\nExcellent interpersonal and communication skills, capable of influencing teams and interfacing effectively with various stakeholders.\n\nAbility to be self sufficient and work autonomously.\n\nA deep interest in game development is a plus.\n\nBased or willing to relocate in Paris\n\nBenefits\nBest-in-class compensation\n\nOther benefits according to the country you reside","description_format":"text","description_chars":4116,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"France","iso":"FR","kind":"country"}],"hiring_excludes":[],"relocation_offered":true,"industries":["Mobile
