RESPONSIBILITIES
Full-Stack Ownership
Ship Across the Stack: Build the React and TypeScript frontends scientists use every day, the Python services behind them, and integrations that reach instruments, Benchling, and agent runtimes
Own It End to End: Take a feature from the first conversation with a scientist through the data model and UI to the alert that fires when it breaks
Do the Normal SWE Things: Write code, review design docs, talk to users, and do code reviews that actually make the codebase better
Agentic Tooling & Experimentation
Chase User Appreciation: Ship things that make scientists say "OMG, this is amazing, thank you so much."
Figure Out What's Actually Useful: Test agentic tooling ideas through prototypes, real users, and short iterative loops rather than betting on theory
Move the Needle: Contribute work that meaningfully advances insitro's mission and the pace of drug development
Cross-Functional Partnership
Go Watch the Work: Spend time in the lab observing the workflow before you change it
Partner Broadly: Collaborate closely with machine learning, automation, and biology teams to build tools people actually use
Keep Humans in the Loop: Design for provenance and verifiability, so a scientist can always check what an agent did and why
ABOUT YOU
Experience & Qualifications
Tenure: 2–4+ years of experience as a professional software engineer
Engineering Fundamentals: Working knowledge of AWS or GCP, relational databases, and standard practices like version control and code review
Core Competencies
Product Instinct: You think like a product person — you want to know who the user is, what they're actually trying to do, and you have opinions about what to build
Curious About the Science: You don't need a biology background, but you want to learn the domain rather than treat it as someone else's problem
Comfortable in the Gray Area: You can reason clearly about the tradeoffs between quality and speed
Fits the Team: You're up for writing design docs, having opinions in code review, and yes, goofing around on Slack.
Preferred Qualifications
Domain Experience: Experience with LIMS, lab automation, or another life sciences domain
Agent/LLM Experience: Experience building with LLMs or agent frameworks — tool and skill design, evaluation, or getting a model to behave reliably against real systems
Stack Familiarity: Experience with Django, FastAPI, SQLAlchemy, React, TypeScript, PostgreSQL, Docker, or AWS

About insitro
insitro is a drug discovery and development company using machine learning (ML) and data at scale to decode biology for transformative medicines. At the core of insitro’s approach is the convergence of in-house generated multi-modal cellular data and high-content phenotypic human cohort data. We rely on these data to develop ML-driven, predictive disease models that uncover underlying biologic state and elucidate critical drivers of disease. These powerful models rely on extensive biological and computational infrastructure and allow insitro to advance novel targets and patient biomarkers, design therapeutics and inform clinical strategy. insitro is advancing a wholly owned and partnered pipeline of insights and therapeutics in neuroscience and metabolism. Since launching in 2018, insitro has raised over $700 million from top tech, biotech and crossover investors, and from collaborations with pharmaceutical partners.
