Join our team in Nottingham
Greentube UK is a leading online games studio, and we're expanding our Software Team. Our office is in the centre of Nottingham, our team has a strong reputation for quality, and we work in a productive, friendly environment. This is a hybrid role (work from home Mondays and Fridays), with flexible hours and a half-day Friday.
Who are we?
Greentube, a subsidiary of Novomatic, is a leading full-service provider in the online and mobile gaming sector and a pioneer in state-of-the-art gaming solutions. Novomatic employs over 23,900 staff across 50 countries, headquartered in Vienna.
What you'll be working on
You'll build the front-end game clients for our online casino games, specifically 2D slots: reels, game logic, UI and animation. Our current engine is a long-established, entirely in-house SDK. The client code is written in Java, but it runs through an in-house converter that compiles it to JavaScript, so in practice you're working with a deliberately constrained subset of Java rather than the full modern toolbox, and the framework handles much of the running of the app for you.
The work is more varied than "building slots" suggests. Alongside creating new titles, a large part of the role involves taking our own existing games and reworking them: reskinning a game with new graphics and themes, and "moving on" a title by adding features, mechanics or fresh visual treatments that make it a genuinely new product rather than a straight copy. We're also building the next generation of our platform, a new C#-based framework that borrows heavily from concepts you'll find in modern game engines (Unity), and bringing our existing titles across onto it. The work spans building new games, evolving established ones, and helping shape the platform they run on.
Who we're looking for
Because our engine is entirely in-house, nobody joins already knowing it. What matters most to us is that you can get productive quickly in an unfamiliar, bespoke codebase, so we're looking for strong fundamentals and adaptability first and foremost. Our engine is long-established and does things its own way; it sometimes predates or ignores modern convention. The developers who thrive here are pragmatic and adaptable, comfortable working within the constraints of the environment rather than adhering to one "correct" way of doing things.
We're not a Unity or Unreal studio and you won't be working in a 3D engine. But if you understand how game engines are put together (component models, scene and asset pipelines, the game loop), those concepts map directly onto our frameworks and are increasingly valuable here.
This is a senior role for an experienced developer who can walk into either our established Java engine or our new C# framework and become productive with minimal guidance, and who's energised rather than frustrated by a bespoke, non-standard environment. A lot of the value here is in the hard, ambiguous problems: working out exactly how one of our own existing games behaves so it can be faithfully rebuilt on the new platform, reworking established titles into something new, and designing new systems where there's little precedent to lean on.
What you'll need
- Several years of commercial software development experience, including significant time spent in large, mature, or legacy codebases
- Strong grasp of OOP, common design patterns, and at least one object-oriented language (ideally Java or C#, given our current and future stacks)
- Genuine comfort picking up and working productively in large, established, or legacy code you didn't write (this is central to the role)
- A pragmatic, adaptable approach to an unusual, constrained, bespoke environment
- Expert problem-solving, able to find avenues of investigation where only minimal information is available
- Full autonomy: able to prioritise and scope your own work without assistance, accounting for external factors and complexity
- Able to make substantial contributions to internal codebases, including designing and implementing entirely new systems
- Comfortable across both our Java engine and the new C#-based framework, or able to get there quickly
- An active role in code-quality standards, with the ability to identify the need for new processes and improve existing ones
- Able to help train, motivate and unblock other developers
- Confident with source control (Git) branching and merge requests in a team
- Comfortable working in a regulated environment (UK Gambling Commission and equivalents), where accuracy and compliance matter
Nice to have
- Any experience of a codebase that compiles or transpiles to another target (for example, Java or C# to JavaScript)
- C#, and tooling such as NuGet and Visual Studio, relevant to the framework we're moving toward
- Understanding of game-engine architecture concepts, as described above
- Commercial experience building games or real-time, interactive UI
- Spine animation, CI and automation, unit testing
Our offer
- Salary based on your experience and skills
- Flexible working hours around core hours
- Half-day Fridays (core hours end at 1pm)
- Hybrid working, Mondays and Fridays from home
- City-centre location
- Strong route for progression, with a preference to promote from within
