Founding Product / Full-stack Engineer
Founding Engineer – Infrastructure & LLM Platform
We’re hiring on behalf of a stealth-mode, VC-backed startup that’s reimagining how LLMs learn, adapt, and scale in production environments. The team is small, highly technical, and led by repeat founders with deep experience in AI systems, distributed infrastructure, and open-source development.
They’re building a platform that empowers developers and enterprises to fine-tune, evaluate, and optimize LLMs in real time — making it radically easier to deploy performant, trustworthy AI at scale.
As a Founding Engineer, you’ll play a critical role in designing and building the infrastructure powering this next-gen platform.
What You’ll Work On:
- Architecting scalable, high-performance backend systems in Rust
- Building the infrastructure to support dynamic prompt optimization, in-context learning, and multi-agent orchestration
- Designing observability and evaluation layers for LLM performance and trustworthiness
- Working closely with ML researchers to productionize cutting-edge techniques
- Shaping the technical roadmap and engineering culture from the ground up
Tech Stack:
- Languages: Rust, TypeScript
- Infrastructure: AWS, Lambda, ECS, S3
- Frontend: Svelte, Tailwind
- Other: Docker, Terraform, Postgres, OpenAI API, custom LLM frameworks
