We help agent developers maintain and improve their ai software by identifying problems and fixing them with changes to scaffolding code, prompts, and models.

As a Founding Full Stack Engineer, you’ll create a product interface for the platform and agent that will help engineers and teams improve and maintain their AI software through specification engineering. Task-driven UX and monitoring visualization are familiar, but you’ll also need to build software that quickly and effectively communicates the vast amount of information baked into experiments, evaluations, and results.

You’ll have significant influence over product direction and the utmost autonomy.

What you’ll be working on

— Task management interfaces for the Research Engineer product.

— Monitoring and specification interfaces to help customers manage and edit their software with Synth
— Interactive agents

What we’re looking for
— Ability to ship consistently and quickly

— Design sensibilities and ability to work effectively with designers

— Clear thinking and a desire to create high-performance, functional software

— Excitement for the prospect of designing new development patterns for AI software


Why join us
— Live on the frontier of agent post-training, prompt optimization, SFT, RL, and code synthesis alongside a team that has been pushing the field for years
— Shape how teams and engineers ship and maintain AI software with new patterns like specification-driven development.
— Operate with full ownership and autonomy; your design and implementation choices set the standard for our user experience

Python

• postgres, redis, modal, fastapi
• vllm, trl TS
• Next.js

Very open to changing JS if there's a good reason.
