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 RoleThe best platforms don't just support a workflow — they transform who can participate in it. At Sesame, we're building lifelike, personal, voice-first, agents. Their quality comes from a tight collaboration between engineers, ML researchers, and the creative professionals who define the personality of the agents.
This role requires full-stack engineering experience with a focus on the internal tooling and platforms that power our agent research pipeline. We're looking for engineers who are excited to build the systems that enable and accelerate that collaboration.
You'll architect and develop the internal platforms that take our team from raw data to fully-realized agents — evaluating quality and iterating cross-functionally through a React-based frontend atop a Python/FastAPI backend, backed by cloud ML infrastructure. The goal isn't just to support what we're doing today; it's to build a platform where our creative and research teams can experiment, iterate, and push the frontier of what's possible in agentic AI.
Responsibilities:Collaborate with research and creative teams to understand their workflows and find opportunities for automation
Design and build internal tools that allow engineers and non-engineers to experiment
Maintain and iterate on tools based on user feedback to continually improve their utility
4+ years experience building internal tools with a strong sense of UI/UX
Experience working with ML research teams
Proficiency with modern web development stacks (React/Next.js, Python/FastAPI)
Experience with cloud infrastructure (GCP/Kubernetes)
Strong sense of reliability and knowing when to build vs. borrow
Knowledge of security and privacy best practices
