We are looking for a Senior Unity Developer to join our Core Game Tech (CGT) Team — the small, senior team behind the technology that every Kolibri game runs on.
Our work spans consulting game teams on technical decisions, investigating problems where nobody has defined the requirements yet, and building the systems and integrations that the games depend on. That ranges from compliance features and third-party SDKs to shared systems, standardization and keeping our engine and tooling current.
You'll work in a small specialized team alongside technical decision makers to have strong impact on all the games across our portfolio.
If you like being the person who takes on the technical problems other teams can't, and you don't shy away from constantly diving into new unknowns, learning new skills and driving topics forward, this role is for you.
Responsibilities
Design and build the shared systems multiple live games with dynamic events and scheduled content for millions of users run on
Drive third-party integrations and keep the portfolio current: evaluate and integrate SDKs, drive SDK and Unity version upgrades, and understand the impact across every game before it lands
Advise game teams as their technical counterpart, driving standardization and winning adoption of shared solutions on the strength of the work and the argument
Deliver compliance and privacy features across the portfolio, such as age assurance APIs, CMP implementations and GDPR data deletion flows
Investigate open-ended technical problems and turn regulations, vendor changes and internal needs into concrete technical requirements
Required skills
(Ideally 5+ years of professional) Software development experience in C# and Unity3D. Experience in non-gaming contexts is also relevant; we value your expertise, so do not hesitate to apply
You have a wide understanding of how Unity works, you are familiar with native implementations, understand backend interactions, and performance investigations are your bread and butter. The most important skill is to be able to jump into the unknown and get familiar
Strong written and spoken communication, and the credibility to make teams you don't sit with want to adopt your solutions
Experience building libraries, packages, APIs or tooling that other developers consume, and an instinct for what makes them adoptable
Ability to plan, communicate, and execute technical solutions in a way that is both understandable for other developers as well as non technical stakeholders
Ability to derive requirements yourself from ambiguous or external sources — regulation, platform policy, vendor documentation — rather than working from a written spec
A genuine appetite for constantly learning new areas of the stack
Desirable skills
Experience debugging below the C# layer into Android and iOS platform code, and profiling performance on mobile
Exposure to compliance, privacy or platform policy work — GDPR, CMP, age assurance, ATT or similar
Familiarity with reactive or async programming and dependency injection frameworks, e.g. UniRx, Zenject, UniTask
A passion for games and an understanding of the mobile market, like F2P and LiveOps
Strong familiarity with using LLMs in different areas of game development to support your efforts and achieve stronger results
Familiarity with Firebase Crashlytics and an understanding of ANRs.
