Senior Client Engineer (Core Tech/Platform Engineering) - Star Trek Fleet Command

Scopely is looking for a Senior Client Engineer to join our Star Trek Fleet Command team within our Midcore division in Dublin, Barcelona, the UK or Portugal on a hybrid/remote basis.

At Scopely, we care deeply about what we do and want to inspire play every day - whether in our work environments alongside our talented colleagues or through our deep connections with our communities of players. We are a global team of game lovers who are developing, publishing and innovating the mobile games industry, connecting millions of people around the world daily.

Star Trek Fleet Command is a standout success in the gaming industry. Launched in 2018, our in-house developed 4X Strategy MMO has continually evolved, earning its place as one of the top-grossing games on the market.

What You Will Do

As a Senior Client Engineer focused on Core Tech and Platform Engineering, you’ll play a critical role in driving the technical evolution of our Unity-based client. This role goes beyond gameplay and focuses on the underlying architecture, tooling, systems, and infrastructure that power the client experience across devices and platforms.

• Lead design and development of shared client systems (e.g., asset loading, event systems, UI framework, serialisation, memory tracking, patching, performance tooling).
• Proactively identify bottlenecks and own long-term solutions to performance, stability, and scalability issues.
• Collaborate with cross-functional teams including Backend, DevOps, and QA, to improve developer workflows, build pipelines, and platform integration.
• Participate in defining and maintaining coding standards, architectural patterns, and engineering best practices across multiple teams.
• Support the Unity version upgrade process and ensure all platform integrations (Android, iOS, desktop) remain performant and stable.
• Own initiatives that increase the modularity and maintainability of the codebase.
• Mentor engineers through code reviews, design sessions, and technical deep-dives.

What We're Looking For

• 5+ years of professional experience with Unity (C#), focusing on systems engineering, tools, or platform development (not just gameplay).
• Proven experience designing and maintaining shared infrastructure, reusable components, or frameworks at scale.
• Strong debugging skills, especially in performance, memory usage, and threading/concurrency.
• Deep understanding of Unity's AssetBundle pipeline, scene loading, addressables, rendering pipeline, and lifecycle.
• Experience with cross-platform development (iOS/Android/PC) and profiling tools (e.g., Instruments, Android Profiler, Unity Profiler, etc.).
• Familiarity with CI/CD pipelines, Jenkins, Git Actions, or similar automation tools.
• Strong collaboration skills to work with cross-functional partners across product, art, and engineering.

Bonus Points

• Unity upgrade and migration experience (e.g., Unity 2021 to Unity 6).
• Experience with native plugins, Unity's Burst compiler, or Jobs system.
• Proficiency in low-level performance optimisation and memory management (e.g., GC, allocations, object pooling).
• Knowledge of Protobuf, WebSocket, gRPC, or custom networking protocols.
• Prior work on LiveOps infrastructure, experimentation platforms, or A/B testing systems.
• Familiarity with backend-client coordination for data sync, event triggers, and telemetry.
• Exposure to mobile-specific challenges: device fragmentation, patching, app store constraints.
