Staff Software Engineer, Developer Infrastructure

About Sesame Sesame believes in a future where computers are lifelike – with the ability to see, hear, and collaborate with us in ways that feel natural and human. With this vision, we’re designing a new kind of computer, focused on making voice agents part of our daily lives. Our team brings together founders from Oculus and Ubiquity6, alongside proven leaders from Meta, Google, and Apple, with deep expertise spanning hardware and software. Join us in shaping a future where computers truly come alive. About The Role At Sesame, our developer infrastructure philosophy is to give engineers superhuman abilities by building tools that possess the same craft quality and customer focus as everything else we do here. Our North Star is Zero Ops dev infra through aggressive automation and careful, detail-oriented tool design. AI is the biggest unlock for automation in a generation and it infuses everything we touch. For the Developer Infrastructure team, every instance of manual effort is an opportunity to solve a customer problem once and for all with great software. At its core, Sesame is a tools company. Join us to build the tools behind a generational device that will Bring the Computer to Life. Responsibilities Own the developer experience from onboarding through deploy — dev environments, build systems, CI/CD, test infrastructure, and deploy tooling Build frameworks and tooling that make CI fast, reliable, and effortless; engineers shouldn’t have to think about it — it should just work Design self-serve tooling that lets product and ML engineers move quickly without filing tickets or waiting on you Give teams clear, reliable visibility into what’s in production, when it shipped, and how it’s performing Explore what it means to bring AI‑assisted intelligence into developer tooling — this is a genuinely exciting frontier, and we’re approaching it thoughtfully Keep the complex systems that support rapid development healthy: build systems, dependency management, test infrastructure, and developer environments all need ongoing care Think creatively about what a performance-sensitive stack — GPUs, co-located servers, real-time requirements — means for the developer environment. There’s no established playbook here, and that’s part of the appeal Required Qualifications Thoughtful software engineer who loves infrastructure; writes clean, well-designed code and cares about the experience of the people using what you build Experience with CI/CD systems and solving hard problems — slow builds, flaky tests, painful merges — with durable solutions Built developer tooling that other engineers genuinely wanted to use: self-serve frameworks, CLI tools, build systems, environment setup, or debugging tools Comfortable in Python and/or TypeScript — our monorepo leans on both 5+ years in software engineering, with meaningful time spent on developer infrastructure or tooling Automation is default: doing something manually twice feels like a problem worth solving Think from the perspective of the engineers using your work; developer experience is the whole job, not a buzzword Preferred Qualifications Experience with monorepo tooling and build systems (e.g., Bazel, Pants, Moonrepo, Nx, or similar approaches) Experience with cloud-based development environments (e.g., Coder, Codespaces, devcontainers) CI platform depth beyond workflow files into managing runners, optimizing costs, and building custom tooling Containerized builds and local/CI parity (e.g., Docker, Dagger) Deploy pipeline patterns: canary deployments, feature flags, automated rollbacks, GitOps AI coding tools — not just using them, but configuring, customizing, or building tooling around them Security engineering in developer workflows: dependency scanning, secrets management, supply chain controls GCP experience Benefits 401(k) max employer match: 3.5% of compensation 100% employer-paid health, vision, and dental benefits for you and your dependents Unlimited PTO and sick time Flexible spending account with employer matching up to $1,650/year (medical FSA) Guardian Employee Assistance Program (EAP) Opportunity to share in the company's success with competitive stock options Benefits do not apply to contingent/contract workers. Compensation Range: $175K - $280K. We welcome all qualified applicants, embracing diversity in race, gender, identity, orientation, ability, and more.
