Job Description
About the Role This is a rare opportunity to join as a Founding Engineer at a fast-moving, Seed-stage AI infrastructure startup building the backbone for the next generation of AI products — from coding assistants to agent orchestration systems and beyond.
You'll work directly alongside the founders to shape the company's technical direction from the ground up. If you're motivated by deep ownership, greenfield architecture decisions, and the kind of impact that only comes at the earliest stage of a company, this role is built for you.
What You'll Do
Design, build, and own core backend infrastructure powering a high-throughput, production-grade AI gateway serving billions of tokens per day. Architect and evolve a pragmatic microservices system — including a core LLM gateway in Go and auxiliary ML/AI services in Python.
Make critical decisions around distributed systems design, database selection, caching strategies, and API platform architecture. Profile and optimize performance for high-traffic, latency-sensitive systems (sub-20ms SLAs). Work hands-on with Kubernetes to deploy, manage, and scale services reliably.
Redefine and evolve the tech stack as the product and team grow — you will be a key voice in those decisions. Collaborate directly with founders to translate product vision into robust, scalable engineering solutions.
What We're Looking For Required: 5+ years of experience building backend services using a compiled language — Go (Golang) strongly preferred . Strong experience in distributed systems design and scalability. Hands-on Kubernetes expertise in production environments.
Deep knowledge of SQL/NoSQL databases and caching layers — and the judgment to choose the right tool for the job. Experience building or designing high-quality API platforms. Experience with performance profiling and optimization for high-traffic systems.
Prior experience at an early-stage startup or on greenfield/founding engineering projects. Strong understanding of concurrency p
