# Full Stack Software Engineer at Medra

- **Company:** Medra
- **Location:** San Francisco, CA
- **Employment:** full-time
- **Work type:** onsite
- **Posted:** 2026-05-13
- **Last confirmed live:** 2026-09-08
- **Apply:** https://jobs.ashbyhq.com/medraai/4b14a964-094b-4bb8-9e92-d0ae183b8e1b

## Job description

## WHAT WE'RE BUILDING:

If you want to shape the future of science, come build with us. Medra is building Physical AI Scientists: robotic systems that work hand-in-hand with leading biopharma partners to enable scientific breakthroughs faster than ever before.

🤖 Physical AI that can operate scientific instruments with human-level dexterity.

🧪 Scientific AI that can analyze results, reason about next steps, and close the loop autonomously.

We shipped our first production system over a year ago, recently raised a $52M Series A, and are opening one of the largest autonomous labs in the US. We're a small, ambitious team and you'd be joining early.

## THE TEAM:

- We’re a team of passionate, mission-driven engineers from companies like Tesla, Amazon, SpaceX, and Neuralink. We’re collaborative and love moving fast, both with our product and on team trips skiing or go-karting!
- As a team, we love nerding out about engineering and robotics — plus other topics like race cars or cooking. We like learning new things and then sharing our new knowledge with each other.
- Our team is opinionated and straightforward. We don’t mind intense discussions about design tradeoffs. If we have arguments or miscommunication, we resolve conflicts quickly and empathetically.

## IN THIS ROLE, YOU WILL:

- Build and own the tools our customers use to design, monitor, and analyze autonomous experiments
- Develop internal systems that help our team deploy, operate, and debug a growing fleet of robots in real lab environments
- Work across the full stack, from React frontends to Node and Python services to AWS infrastructure, shipping features end-to-end
- Collaborate directly with scientists, operations, and robotics engineers to understand their workflows and build software that makes their work easier and faster
- Shape the engineering culture and technical direction of a product that's redefining how life science R&D gets done

Let's talk if you have:

- 3+ years of full-stack engineering experience at product-driven companies
- Practical experience building AI-driven workflows into products
- Strong proficiency in Python and TypeScript, with experience building production React applications
- Comfort working across the stack: frontend UI, backend services, cloud infrastructure (AWS)
- A track record of shipping end-to-end. You've taken features from idea to production, not just written code to spec
- A bias toward action and ownership. You thrive when things are loosely defined and move fast
- Genuine curiosity about what you're building and who you're building it for

## About Medra

## Company Overview
- **One-liner**: Building autonomous Physical AI for the lab to accelerate scientific discovery by executing and optimizing experiments in a closed loop.
- **Entity Type**: Private (Series A)
- **Headquarters**: San Francisco, California, United States (340 Pine Street, Suite 100)
- **Founded**: 2021 (some sources cite 2022 – conflicting reports)
- **Founders**: Michelle Lee (CEO)

## Core Business
- **Primary industries**: Life sciences automation, laboratory robotics, AI-driven experimental design
- **Target customers**: B2B – biopharma companies, academic research labs, government agencies (e.g., DARPA)
- **Mission / purpose**: Unlock breakthroughs at scale by tightly integrating AI scientific reasoning with physical experimentation.

## Products & Services
- **Physical AI Lab (Medra Lab 001 – ML001)**: A fully autonomous robotic workcell that executes wet-lab protocols (e.g., CRISPR, cell culture, NGS) using computer vision and robotic manipulation. Instrument-agnostic and modular.
- **AI Experimentalist**: The scientific reasoning layer that translates natural-language research goals into executable experiment plans, coordinates multi-step protocols, analyzes results, and refines methods in a closed loop.
- **Platform Type**: Physical AI + Scientific AI as a service (on-site deployment or remote operation via ML001).

## Market Standing
- **Valuation / Market Cap**: Not publicly disclosed
- **Key Metric**: Total funding of $63M (Series A of $52M closed December 2025, preceded by $11M pre-seed in October 2025 and a non-equity assistance from PharmStars in 2023)
- **Notable Investors / Partners**: Human Capital (lead), Lux Capital, Menlo Ventures, Catalio Capital, Neo, 776 (Seven Seven Six), Fusion Fund, Nat Friedman & Daniel Gross
- **Growth Signals**:
  - Headcount grew 100% YoY (31 employees as of mid-2026)
  - Launched ML001 in San Francisco (April 2026) — largest autonomous lab in the U.S.
  - Announced DARPA collaboration (June 2026) to advance natural-language-to-executable-experiment capabilities
  - 8 open positions across biology, engineering, design, and operations

## Competitive Advantages
- **Closed-loop integration**: Combines physical execution with AI-driven experimental design and learning – not just robotic task automation.
- **Instrument-agnostic & modular**: Works with both manual and automated lab instruments, allowing easy swapping of modules and protocols.
- **Natural-language programming**: Scientists can edit protocols in plain English (written or voice).
- **Scalable data generation**: Logs every action, video, and metadata per sample for traceability and model training.

## Strategic Focus
- Expand partnerships with biopharma, academia, and government (DARPA is a key early customer).
- Advance the AI Experimentalist layer to enable full autonomous hypothesis generation and validation.
- Scale deployments of Physical AI Labs on-site and remotely through ML001.

## Why Work Here
- **Culture**: Described as “intense curiosity and rigorous debate” with clear, direct communication and quick resolution of conflicts through mutual respect.
- **Team**: Community of diverse thinkers, “not just a company but a movement to transform biotechnology.”
- **Work policy**: Likely on-site at the San Francisco lab given the nature of physical robotics; no explicit remote/hybrid policy mentioned.
- **Perks & highlights**: Opportunity to work on cutting-edge AI + robotics with a high-impact mission; funded by top-tier VCs; strong engineering culture (43% technical staff, many from Neuralink, Applied Intuition, Amazon, Carnegie Mellon).
