Senior Software Engineer — Diagnostics Team

Unity Unity · Enterprise · Montreal, QC · Engineering

Senior Software Engineer on the Diagnostics team at Unity, focusing on backend systems for game telemetry and observability. The role involves leading end-to-end design of ingest, pipelines, and data storage, writing Go services, and critically, integrating and evaluating agentic AI tools as part of the development workflow. Requires production experience with Go, strong judgment, and hands-on fluency with AI coding agents.

What you'd actually do

  1. Lead end-to-end design across ingest, pipelines, ClickHouse storage and query, and the dashboards developers rely on.
  2. Write and maintain high-quality Go services that handle attacker-controlled inputs at scale, with strong attention to reliability, performance, and clean data contracts.
  3. Raise the bar on code review and AI-assisted output review — set the norms the team uses when shipping work alongside coding agents.
  4. Partner across teams (Data, IAP, Unity Profiler, DevX, Analytics) to design integrations that hold up under real production load and real customer needs.
  5. Mentor engineers across the team, share patterns broadly, and decompose ambiguous problems into the highest-value path forward.

Skills

Required

  • Production experience with Go in high-throughput services
  • 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.
  • Experience designing for and querying NoSQL or OLAP/columnar data stores
  • Excellent collaboration and communication

Nice to have

  • Genuine interest or experience in observability and telemetry (OpenTelemetry especially)
  • Front-end experience with TypeScript and contributions to dashboard-style surfaces
  • Production experience with Kotlin
  • C# exposure on the engine side
  • Gaming background
  • Habits around handling user data responsibly

What the JD emphasized

  • Real, hands-on fluency with agentic AI workflows
  • You review model output as rigorously as PR code, and can defend any line of it in your own words.
