About the opportunity
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 the Unity LiveOps organization and is responsible for the data that tells creators how their games are actually behaving in the wild: Unity runtime crash reports, telemetry and observability across customer projects, product health analysis, and the Unity dashboard surfaces that provide this data back to developers.
We are looking for a Senior Software Engineer to join the Diagnostics team as a backend-leaning generalist. You will lead end-to-end design across our stack—ingestion from millions of game clients, pipelines built on OpenTelemetry, a data lake based on ClickHouse, and the dashboard surfaces that customers depend on—and collaborate closely with the Data, IAP, Profiler, and DevX teams on the integrations that make Diagnostics truly useful. Our stack is composed of Go (primarily), Kotlin, TypeScript, and C#. This is a small, autonomous team where senior judgment has an exponential impact: you will define how the team designs, reviews, and ships its solutions, including how we use agentic AI tools as an integral part of our development practice.

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 for ingest, pipelines, ClickHouse storage and queries, and the dashboards that developers rely on.
- Write and maintain high-quality Go services capable of handling attacker-controlled inputs at scale, with a focus on reliability, performance, and clear data contracts.
- Raise the standards for code review and AI-assisted output review — define the norms the team uses when delivering work in collaboration with coding agents.
- Collaborate with various teams (Data, IAP, Unity Profiler, DevX, Analytics) to design robust integrations under production conditions that are tailored to real customer needs.
- Mentor engineers on the team, share best practices broadly, and break down ambiguous problems into concrete paths that maximize value.
- 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, as well as comfort with a wide range of backend tasks (ingest, pipelines, storage and OLAP/columnar queries, dashboards as needed).
- Demonstrate senior-level judgment: have led cross-functional designs, raised the bar for development, and mentored peers and individual contributors around you.
- Possess real, hands-on experience with agentic AI workflows: have used coding agents (Claude Code, Codex, Cursor agent mode, Gemini CLI, or equivalent) on concrete work, developed an informed opinion on their trade-offs, and designed robust harnesses, prompts, or sub-agents that handle variance. Review model outputs with the same rigor as PR reviews, and be able to defend every line of code in your own words.
- Experience in designing and querying NoSQL or OLAP/columnar data stores (ClickHouse is a plus), as well as a practical end-to-end understanding of data pipelines.
- Possess excellent collaboration and communication skills, with the ability to work effectively across multiple teams and time zones.
- 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
- A genuine interest or experience in observability and telemetry (OpenTelemetry in particular) — this is our core business.
- front-end experience with TypeScript and contributions to dashboard-style surfaces. backend is the priority for this role; front-end skills are a welcome asset, without being a daily expectation.
- Production experience with Kotlin, or exposure to C# on the engine side.
- A background in the video game industry — understand how developers consume diagnostics, and what game performance and profiling mean concretely for them.
- Adopt responsible habits in managing user data: consider trust boundaries, retention, hygienic logging (no personally identifiable information, no tokens, no full payload content), and threat modeling before implementing a feature.

- 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.
