About the role
As a senior backend engineer, you will join the team responsible for building and maintaining TypeSafe's API platform for inference. These APIs will be user facing, latency sensitive, and have uptime, reliability and backwards compatibility requirements. You'll be wearing many different hats and working across different levels in our inference system, with particular depth in distributed systems and networking. Responsibilities include:
Define APIs for a new kind of AI inference experience and iterate on the design to ensure they are delightful to use
Create robust infrastructure for serving inference across multiple cloud providers
Define abstractions that will serve us moving forward as our billing needs and business logic needs grow
Work on exposing new model features to users
Our tech stack is primarily Python. We also use TypeScript, Next.js, and Tailwind CSS for frontend, with Kubernetes for orchestration. We empower developers to use any tooling they find helpful for getting their job done, including AI and agents.
We expect that you
Are responsible, ownership-inclined, and a team player – you believe there is no such thing as "other people's code", and will complain only the normal amount about pager duty
Have experience designing storage abstractions for scaled backend systems
Have experience designing resilient systems and improving on-call experience on production systems
Collaborate well with others on technical and product design, advocating for what you need, and adjusting specs to changing requirements and feedback
Are mission aligned and excited to go all-in
Love being part of a team
We are hoping that you
Have previously built big things
Have 5+ years of professional software engineering experience (3+ years of infra/backend) with a team with rigorous engineering standards
Have shipped backend services at scale with continuous delivery and uptime SLAs of at least 3 9s
Have designed and operated a developer-facing API service
Have experienced LLMs' capabilities and limitations from implementing them in the past
