Software Engineer (Full-Stack)

ABOUT THE ROLE

We're a YC-backed AI developer tools startup (11–50 people, Seed stage) building intelligent AI agents that transform complex technical documentation into accurate, trustworthy self-serve experiences. Our platform helps technical companies deploy AI-powered assistants that answer product questions instantly — reducing support load and accelerating user onboarding.

We're looking for a hands-on Full-Stack Software Engineer to join our small, high-impact engineering team. You'll work closely with the founding team and research engineers to scale our RAG engine, expand our analytics platform, and deepen integrations with a wide range of technical data sources. Your work will be visible, meaningful, and shipped quickly.

WHAT YOU'LL DO

• Work directly with the founding team and research engineers to define and implement features end-to-end.

• Scale the backend infrastructure powering our Retrieval-Augmented Generation (RAG) engine using Python.

• Experiment with and build new features in our analytics platform (React + Python).

• Develop and maintain client integrations used to deploy the product for customers (React + Python).

• Enable access to new kinds of data sources through Python-based ingestion pipelines.

• Maintain and improve our React SDK.

WHAT WE'RE LOOKING FOR

Must-haves:

• 3+ years of full-stack software engineering experience building complex systems with both Python backend and React frontend.

• Strong proficiency in Python and JavaScript/TypeScript.

• Demonstrated experience building AI assistants or NLP-driven applications.

• Hands-on experience with machine learning, deep learning, and LLMs.

• Experience with Retrieval-Augmented Generation (RAG) architectures.

• Strong CS fundamentals — degree in computer science, mathematics, statistics, or a related field, or equivalent practical experience.

Nice-to-haves:

• Prior experience in a startup environment.

• A marker of excellence: work at a recognized technology company, published research, significant open-source contributions, or a notable side project.

• Familiarity with natural language processing techniques and tooling.

COMPENSATION & BENEFITS

• Salary: $100,000 – $150,000 USD annually

• Visa sponsorship: Available
