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 were 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 Sesames 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 youve 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 youve 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

Wed love to hear about experience in most of these areas we dont 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 youve 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
