Founding Engineer

Billions of people still suffer from every-day diseases.

One key reason? Clinical trials are broken.

Despite $120 billion spent each year, most trials are delayed due to bottlenecks like patient recruitment.

Delfa is fixing this with autonomous AI agents. We're building AI agents to automate clinical trials.

In the last year from we’ve already:

- Deployed onto 500+ trials across multiple conditions

- Reached seven figures in ARR, growing 25% MoM

- Raised an oversubscribed $3.8m seed from tier-one AI investors

You'll build and scale the core systems that enable Delfa's AI agents to deliver real-world clinical impact.

Our current tech stack:

FastAPI · Pydantic · TypeScript · React · OpenAI / Anthropic · Temporal · PostgreSQL · Honeycomb · PlanetScale · Azure

• You have 3+ years of professional full-stack engineering experience: We're looking for somebody comfortable with solving hard technical problems, refactoring when needed, and knowing what's enough and what's too much to solve a problem.
• A track record of building high-quality products fast: Delfa's got big ambitions to materially accelerate getting life saving treatments to market. This is necessary and urgent work so we need individuals who can deliver.
• An ownership mindset: We position our team to understand customer problems, give you the autonomy to find the best path forward, and expect you to own the solutions.
• A growth mindset: We're looking for people who take pride in their work and are always looking to improve it. If your work doesn't matter to you, it won't end up mattering to our customers. If you're not growing, your impact won't grow either.

Delfa is building a generational company to transform the way medications reach millions of patients in need.
