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

We care more about how you think and what you've built than which specific tools you've used. Here's what success looks like in this role:

You're a thoughtful software engineer who also loves infrastructure. You write clean, well-designed code and care about the experience of the people using what you build
You've worked on CI/CD systems and have real experience solving the hard problems — slow builds, flaky tests, painful merges — with durable solutions
You've built developer tooling that other engineers genuinely wanted to use: self-serve frameworks, CLI tools, build systems, environment setup, or debugging tools
You're comfortable in Python and/or TypeScript — our monorepo leans on both
You have 5+ years in software engineering, with meaningful time spent on developer infrastructure or tooling
Automation is your default. Doing something manually twice feels like a problem worth solving
You think from the perspective of the engineers using your work. Developer experience isn't a buzzword to you — it's the whole job

Preferred Qualifications

We'd love to hear about experience in any of these areas — but we don't expect any one person to have all of them:

Monorepo tooling and build systems (e.g. Bazel, Pants, Moonrepo, Nx, or similar approaches)
Cloud-based development environments (e.g. Coder, Codespaces, devcontainers)
CI platform depth — going beyond workflow files into managing runners, optimising costs, and building custom tooling
Containerised 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, customising, or building tooling around them
Security engineering in developer workflows: dependency scanning, secrets management, supply chain controls
GCP experience
