Job description

We are looking for an experienced engine programmer to join one of our internal engine teams, which is responsible for the core runtime and platform layer of Supercell’s in-house game engine. The engine teams are independent teams that maintain our internal tech stack and work seamlessly with our game teams to revolutionize the way we develop games at Supercell.

You will be focused primarily on our multi-platform C++ game engine. You will be expected to iterate and integrate improvements to the engine and its subsystems while working alongside coders, designers and artists from game teams, as well as other core technical teams.

We’re looking for someone like you, who ideally has years of experience, and knowledge acquired from the gaming industry. Whether you have broad experience in proprietary game engines or are a specialist in one area – we want to hear from you. To be successful in this role, you will need to be a proactive programmer who works directly with game teams to deliver world-class mobile games.

If this sounds like you and you're interested in finding out if Supercell would be a great fit for you – hit that apply button.

Read about the engine behind every Supercell game (and why you’ve never heard of it).

What you’ll be doing

• Develop, maintain, and improve core engine systems used across all our games.
• Design and evolve platform abstractions for iOS, Android, Windows, and macOS.
• Work on runtime systems such as memory management, threading/job systems, asset loading, and performance‑critical infrastructure.
• Collaborate closely with game teams to identify bottlenecks and improve iteration speed, stability, and usability.
• Improve developer workflows and tooling to make our engine a compelling alternative to off‑the‑shelf solutions.
• Continuously modernize a large, long‑lived codebase while supporting live games in production.
• Work across team boundaries, ensuring clean integrations between core systems, rendering, and gameplay layers.

What you have

• Experience with in‑house or proprietary game engines.
• Strong professional experience with C++ in production environments.
• Experience working with large, existing codebases, and the ability to improve them incrementally.
• Solid understanding of core engine systems (e.g. memory, threading, asset management, runtime architecture).
• Experience designing or working with cross‑platform systems, especially for mobile (iOS/Android) and desktop (Windows/macOS).
• Understanding of mobile performance characteristics (CPU, memory, threading, and platform constraints).
• Ability to collaborate with both technical and non‑technical team members.
• Pragmatic problem‑solving mindset and a focus on delivering real‑world impact.
• A self‑starter approach to use AI: you've found ways to use it in your day‑to‑day work, you experiment, figure things out and bring the same energy to every new challenge.

Would be also nice if you have

• Familiarity with build systems and tooling (e.g. CMake, Gradle, Python, CI pipelines).
• Experience improving developer workflows, iteration times, or debugging tools.
• Experience with UI/tooling frameworks such as ImGui.
• Experience in game server development and Java.
• Experience from game console platforms.

Why This Role Matters

Our engine has been developed over many years and powers multiple live games at global scale. We are actively evolving it to better support current and future titles.

• Making the engine more stable, faster, and easier to use.
• Helping game teams ship and operate live games more effectively.
• Contributing to a long‑term effort to build world‑class internal technology.

Where You’ll Be

The team is based in Helsinki, which is the preferred location for this role.
