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 qualifications We'd love to hear about experience in most of these areas — we don't expect any one person to have all of them
Infrastructure as Code at scale — significant IaC experience, preferably Terraform; CloudFormation, Pulumi, or Kubernetes-based approaches also welcome. Ideally you've architected, maintained, or contributed to a multi-stack, self-serve IaC system and understand the challenges of building infra that teams can own independently
ML infrastructure — any combination of the following:
PyTorch experience, especially model optimization for serving
ML training or serving experience in general
Experience building ML serving and/or training infrastructure (TorchServe, Seldon, KServe, Ray Serve, or similar)
Experience building large‑scale distributed training and serving systems
Data engineering — pipeline design, dataset management, or data platform experience
Database design — complex schema design, query optimization, and hard data modeling decisions across relational and non‑relational stores
Real‑time communication systems — low‑latency audio, video, or streaming infrastructure
Sesame is committed to a workplace where everyone feels valued, respected, and empowered. We welcome all qualified applicants, embracing diversity in race, gender, identity, orientation, ability, and more. We provide reasonable accommodations for applicants with disabilities. Contact careers@sesame.com for assistance.
Full‑time Employee 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.
