Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Staff Software Engineer - **Company:** Unity Technologies - **Location:** Mountain View, CA, United States - **Salary:** $192,600 - $317,800 - **Contract:** Permanent contract - **Skills:** Artificial Intelligence, Microsoft Azure, Code Generation, Code Review, Continuous Integration, Software Debugging, Memory Management, Service Development Studio, Data Logging, Google Cloud, Large Language Models, Grafana, Backend, Api Design - **Published:** November 5, 2026 - **Apply:** https://www.indeed.com/viewjob?jk=0bbae2aa0bb834b2 ## About the Role * Hands-on, current use of AI and agent tooling in your own engineering work. Genuine daily practice, not familiarity with the concepts - and ideally experience pointing agents at problems beyond code generation. Expect to talk about what you have actually built * A track record of setting technical direction that other people followed - choosing what to build and what not to, making the case, and owning the outcome when it was expensive to be wrong * A track record of working on problems that weren't defined when you started - framing them, moving quickly to something real, and knowing when to change course * Experience building and shipping complex, user-facing software products at scale * Depth in observability - monitoring, logging, alerting and debugging with tools such as Grafana - and a point of view on making telemetry interpretable rather than merely present * An automation instinct in operational work - you have replaced a manual judgment step in production with a system that makes it for you, or cut the human effort in a detection-to-resolution loop * Hands-on experience with Microsoft Azure or Google Cloud Platform * Backend service development, including API design, and comfort working in an established CI/CD and infrastructure-as-code environment * Evidence of multiplying other engineers - mentoring, design review, or standards that outlived your involvement * Ability to translate business and user needs into technical solutions * Strong communication and interpersonal skills, with a proven ability to align stakeholders across disciplines and organizations We would rather hire someone exceptional in a few of these areas than adequate across all of them., This is a broad charter, and we don't expect anyone to arrive with all of it. If you're strong across most of the above and curious about the rest, we'd like to talk. * Experience building evaluation infrastructure for AI systems - benchmark harnesses, LLM-as-judge pipelines, or measuring model output quality at scale * Experience with the economics of agentic systems - inference and token cost, model routing, context and memory management, or checkpointing and state recovery for long-running agent work * Background in games, live-service operations, or player analytics Base Salary Range: We determine the base salary range for this role based on your primary work location ## Description * Own how this team builds software with AI. We use AI across our workflow today and we're not satisfied with how far it goes. You'll set the standard - agentic code review and repair, generated tests that stay honest as requirements change, the tooling and patterns the team adopts because they make the work faster. Not just working this way yourself, but moving the floor for everyone, and having the judgment to tell a tool that earns its place from one that doesn't. * Define what we measure, and rebuild observability so it explains itself. Our telemetry has gaps, and much of what we collect is ambiguous, unlabelled, or only meaningful to whoever built it. You'll own the model of system health and business outcomes across our platform, make each metric self-explanatory, and replace manual review and manual reaction with automated interpretation. * Make diagnosis agentic, and decide how far that should go. Build the troubleshooting layer that correlates signals, proposes root causes, and takes safe automated action - so that understanding a production issue doesn't start with a person reading graphs. Where the automation stops and a human stays in the loop is a judgment call with real blast radius, and it's yours to make. * Own the infrastructure side of evaluation, as the technical counterpart to our Quality Engineering Lead. Our products generate code, find and fix bugs, and produce art and design - output with no single correct answer. We have the beginnings of an evaluation system and it isn't mature yet. You'll make evaluation fast, repeatable and cheap enough to run continuously, working as the engineering peer of the lead who owns the methodology. * Decide what AI does for gaming LiveOps. Live games are managed continuously after launch: events and content, player behaviour and retention analysis, monetization, live health. We think Unity's data puts us in an unusual position to make that faster, smarter and far less manual. We are early here and genuinely do not know yet what it becomes. We're not asking you to execute a plan - we're asking you to form one, defend it, and know when to abandon it. * Make agentic systems affordable. As more of our product and our own workflow runs on inference, the economics become an engineering problem - token efficiency, routing work to the cheapest model that can do it, managing what an agent has to keep in context, and recovering agent state so a failed run resumes instead of starting over. You'll own how we measure and optimize all of it, and set the budgets the rest of us build within. * Set technical direction for Unity AI's backend platforms. Make the architectural calls that are expensive to reverse, run technical spikes with developers on Microsoft Azure and Google Cloud, and partner with product, design and other engineering teams to shape the roadmap rather than receive it. * Raise the engineers around you. Design review, code review, mentoring, and the kind of technical argument that leaves the other person better at their job. We measure Staff impact partly by what the people near you are able to do a year from now., This position requires the incumbent to have a sufficient knowledge of English to have professional verbal and written exchanges in this language since the performance of the duties related to this position requires frequent and regular communication with colleagues and partners located worldwide and whose common language is English.
