About Alchemi
It takes more than a decade and over $2 billion to bring a new drug to market. Alchemi builds AI that helps drug development teams move faster, and we already work with some of the largest pharma companies and CROs in the world.
The role
The agents are the product. You'll build them end to end: take a real workflow, figure out how experts actually do it, and ship an agent good enough that some of the most demanding customers in the world trust it. Small team, huge scope, and your work goes in front of customers within weeks.
What you'll do
Build and ship agents, from tools and retrieval to orchestration and model choice.
Write the evals that prove they work, and keep raising the bar.
Work side by side with our scientists and customers.
Turn one-off wins into reusable pieces of the platform.
What we're looking for
You've built LLM apps or agents that real people use, not just demos.
Strong Python and good engineering habits.
You ship fast and learn faster.
You're obsessed with how you know something actually works.
Early in your career is fine. We care about slope, not years.
Nice to have
Side projects, hackathon wins or open-source work you're proud of.
How we work
Small team, low process, high trust. Two-week release cadence, design specs reviewed carefully, and an active resistance to ticket sprawl. Based in New York City, with daily overlap across a team that spans Pacific Time to Western Europe.
Why join
Our goal is to cut years off clinical development timelines. Alchemi has already supported more than 3,000 studies for the top development teams in pharma. We're a small team of experts. We keep talent density high and work closely across every part of the product, from first idea to deployment.
Impact: Your work goes straight into the regulated workflows that decide how fast drugs reach patients.
Excellence: Work alongside a highly skilled team in a fast-paced, high-impact environment.
Ownership: Help shape product direction, how we work and what we build next.
What we offer
Salary and equity: Competitive salary and meaningful equity, with options weighted toward ownership if that's what you want.
Health: Best-in-class health and dental insurance.
Time off: 4 weeks of paid vacation plus public holidays, paid sick leave and parental leave.
Location: Based in New York City.
Equipment: A MacBook, external monitor and accessories.
Growth: Room to learn and develop in a cutting-edge field.
