What you'll do

- Design, build and iterate on RAG pipelines that turn messy, domain‑specific documents into actionable insights, ensuring data privacy and security throughout

- Ship thin vertical slices across the stack, rapidly and autonomously

- Use and extend our in‑house benchmarking framework to evaluate quality, latency and cost of every AI workflow

- Collaborate directly with founders and early customers to transform fuzzy ideas into shipping plans

- Influence technical direction and engineering culture as we grow from <10 to 30+ people

- Follow secure coding practices and contribute to maintaining our information security standards

- Participate in security awareness initiatives and apply security best practices in daily development work


You might be a fit if you…

- Have 5**+ years** of professional software engineering or equivalent startup hustle

- Are fluent in Python

- Possess hands‑on expertise with LLMs & vector search (prompt engineering, embeddings, evaluation)

- Enjoy diving deep into gnarly data until every edge‑case makes sense

- Thrive in early‑stage ambiguity: self‑directed, outcome‑oriented, biased to action
