About the role
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.
Responsibilities Design and build secure, maintainable, self-serve core infrastructure that engineering teams can rely on and operate independently Architect and evolve a modern ML training infrastructure — scalable, reproducible, and built for rapid experimentation Build and operate a modern model serving architecture with a focus on reliability, cost efficiency, and low latency Own and scale the low-latency voice interface and audio processing pipeline — a technically demanding, performance-sensitive system at the core of Sesame's product Build developer tooling, server infrastructure, and data infrastructure that is high leverage and low maintenance — the kind that makes other engineers faster without creating new dependencies on you Set technical direction within your domain, bring others along through clear communication and well-reasoned proposals, and raise the engineering bar across
the team Required
Qualifications A strong systems thinker who is equally comfortable setting direction and getting hands-on with implementation Hands-on reliability engineering experience — you have well-formed convictions about observability, monitoring, deployment systems, and loosely coupled architectures, and you've put them into practice at scale Proven track record of shipping services at scale, with all the operational complexity that comes with it Kubernetes — significant production experience operating and scaling Kubernetes clusters Experience designing and shipping flexible domain models and APIs — you think carefully about boundaries, contracts, and long-term maintainability A default toward automation — you've consistently delivered efficiency gains through automation and have the track record to show it Strong communication skills — you can set your own direction, write clearly about tradeoffs, and bring engineers and stakeholders along with you 3+ years of software engineering experience, with significant time in infrastructure, platform, or ML systems roles Preferred
