Senior Software Engineer Diagnostics Team

The opportunity
Developing the Unity platform means designing, building, testing, and maintaining the systems that empower developers to ship and operate live games at scale. The Diagnostics team sits inside Unity's LiveOps umbrella and is responsible for the data that tells creators how their games are actually behaving in the wild — crash reports from the Unity runtime, telemetry and observability across customer projects, product health analysis, and the Unity Dashboard surfaces that put that data back in developers' hands.

We are seeking a Senior Software Developer to join the Diagnostics team as a backend-leaning generalist. You will lead end-to-end design across our stack — ingest from millions of game clients, pipelines built on OpenTelemetry, a ClickHouse-based data lake, and the dashboard surfaces customers depend on — and you will partner closely with the Data, IAP, Profiler, and DevX teams on the integrations that make Diagnostics useful. Our stack is Go (primary), Kotlin, TypeScript, and C#. This is a small, autonomous team where senior judgment compounds: you will shape how the team designs, reviews, and ships, including how we work with agentic AI tools as a core part of the craft.

What you'll be doing

• Lead end-to-end design across ingest, pipelines, ClickHouse storage and query, and the dashboards developers rely on.


• Write and maintain high-quality Go services that handle attacker-controlled inputs at scale, with strong attention to reliability, performance, and clean data contracts.


• Raise the bar on code review and AI-assisted output review — set the norms the team uses when shipping work alongside coding agents.


• Partner across teams (Data, IAP, Unity Profiler, DevX, Analytics) to design integrations that hold up under real production load and real customer needs.


• Mentor engineers across the team, share patterns broadly, and decompose ambiguous problems into the highest-value path forward.

What we're looking for

• Production experience with Go in high-throughput services, plus comfort moving across a backend-leaning generalist surface (ingest, pipelines, OLAP/columnar storage and query, dashboards when needed).


• Demonstrated senior-level judgment: a track record of leading cross-cutting design, raising the engineering bar, and mentoring peers and ICs around you.


• Real, hands-on fluency with agentic AI workflows — you have used coding agents (Claude Code, Codex, Cursor agent mode, Gemini CLI, or similar) on real work, formed informed opinions about their trade-offs, and built harnesses, prompts, or sub-agents that hold up under variance. You review model output as rigorously as PR code, and can defend any line of it in your own words.


• Experience designing for and querying NoSQL or OLAP/columnar data stores (ClickHouse a plus), and a working understanding of data pipelines end to end.


• Excellent collaboration and communication, with the ability to work effectively across teams and time zones.

You might also have

• Genuine interest or experience in observability and telemetry (OpenTelemetry especially) — this is our bread and butter.


• Front-end experience with TypeScript and contributions to dashboard-style surfaces. Backend is the primary lens for this role; front-end capability is a welcome bonus, not a daily expectation.


• Production experience with Kotlin, or C# exposure on the engine side.


• Gaming background — context for how developers consume diagnostics, what game performance and profiling actually mean to them.


• Habits around handling user data responsibly: thinking about trust boundaries, retention, hygienic logging (no PII, no tokens, no full payloads), and threat-modeling features before writing them.
