Airtree is advertising this role on behalf of one of our portfolio companies, who are currently in stealth mode.
We exist to drastically increase access to advanced medicines.
We're hiring a software engineer to build the systems behind the foundry: software that runs lab and factory equipment, coordinates production work, tracks materials and creates the records regulated manufacturing requires.
Why this role exists

This is an early-career role with a high bar. We're looking for people who've done hard work well and can sustain a high rate of delivery, whatever field that evidence comes from.
You will work with scientists and operators to understand real problems, decide what matters most and choose how to solve it. You will get broad goals and own the detailed path from need to live software.
Our products are AI-native: AI agents will write a large share of the code. Your job is to understand what each system must achieve, turn that into transparent tests, and verify the generated code on live lab and factory systems. That takes care, technical judgement and thorough testing. You stay responsible for the result, regardless of what wrote the code.
What you'll own

During your first 3-6 months,



you will help build and improve software for equipment control, process coordination, electronic work records and material tracking.
Work with scientists and operators to turn real needs into clear requirements and priorities.
Build Python services, process-control software, TypeScript and React interfaces, APIs and PostgreSQL data models.
Connect software to physical equipment through interfaces such as Modbus and OPC UA.
Deploy and operate systems on AWS.
Use AI agents to generate, review, test and debug software, and take responsibility for what they produce.
Verify that software does what it needs to, through code review, automated tests, simulation and controlled trials on live equipment.
Test normal operation, failure cases, data integrity, equipment responses and safe recovery.
Own production systems: monitoring, support, incident response and on-call work.

Much of this work supports regulated, mission-critical or safety-affecting systems. You're responsible for their behaviour, including code an AI agent produced. Cloud and infrastructure work exists to support the core job: improving lab and factory systems.
