• David (Co-Founder, CEO) is a Stanford postdoctoral scholar and Damon Runyon Cancer Research Fellow who has spent 15+ years on the science this platform automates, with foundational publications across the Nature family of journals, the Journal of the American Chemical Society, and other leading scientific publications.
• Andrew (Co-Founder, COO) trained at the Broad Institute of MIT and Harvard, where he built the analytical tools pharma uses to understand how drugs bind their targets, before joining the Bertozzi lab at Stanford.
• Vishnu (Co-Founder, CTO) is a 2x YC founder who was the founding engineer at Nooks and helped scale them through their Series B. You will report directly to Vishnu.

We are already working with multiple top-10 pharma companies and have enterprise contracts in motion. We are well-capitalized and focused on building.

The Role

You will join a three-person founding team and build the core platform from the ground up. You will pair-program directly with the founders on bare-metal, high-throughput, AI-native software that is already being deployed to top-10 pharmaceutical companies.

This will be the highest-leverage work of your career. The systems you build will process data that no existing software can handle at the speed and accuracy our customers require. You will write fundamental algorithms, architect performance-critical infrastructure, and ship code that reaches production on a weekly cadence. The problems are genuinely hard, genuinely novel, and have a direct line to patients receiving better medicines faster. You will be reporting directly to the CTO, Vishnu.

Our Culture

We are a small team that moves with extraordinary momentum. We are building something that has never existed before, and we are doing it on a timeline that most people would consider unreasonable. That is by design. We believe the best work happens when exceptional people commit fully to a mission that matters, when they operate with total ownership, and when the pace itself becomes a source of energy rather than fatigue.

We are looking for people who share that drive. People who are frustrated by bureaucracy and convention. People who want to shape the next era of scientific advancement and are ready to match the commitment of a founding team that moves at the highest velocity. If you want to work at the frontier of what is possible, with teammates who hold each other to the highest standard, this is the role for you.

We are also deeply committed to your personal and professional growth. Whether you want a long-term career as a founding member of 10x Science or plan to start your own company someday, we will invest in your development and support either path.

What You Will Do

•     Build and own core modules of a high-performance scientific computing platform from first principles

•     Architect systems for throughput, correctness, and scale across large and complex datasets

•     Work directly with the founding team to translate deep scientific domain knowledge into production software

•     Deploy to enterprise pharmaceutical customers and iterate based on real-world feedback

•     Make foundational technical decisions that will define the platform for years to come

First 90 Days

You will ship production code in your first week. Within your first month, you will own a core module of the platform and make architectural decisions with real consequences. We do not have an onboarding program. You will learn by building, pair-programming with the founders, and deploying to customers who are counting on what you build. The pace is fast and the stakes are real from day one.

You Will Succeed If You Have These Skills

1.     Low-level systems architecture. You know how to architect low-level systems in Rust. It could be writing novel kernels because you were fed up with PyTorch, or even a library for processing a web app’s data. If you are comfortable with another systems language like C, C++, or Go, you do not need to learn Rust syntax before meeting with us. You should be comfortable applying your practical implementation skills across languages.

2.     Intuition for compute-performance tradeoffs. You have a sense for when to apply zero-parameter, zero-time leverage (XSA, Partial RoPE, Late QAT, etc.) versus forcing the silicon to reveal its absolute limits by benchmarking compilers and GPUs.

3.     Obsessed with interpretability. You care deeply about understanding why a system behaves the way it does, not just that it works.

4.     Leverage the best available tools. You adopt AI coding agents, CLI tooling, and anything else that multiplies your output. You are not attached to doing things the old way when a better way exists. The speed at which you incorporate new tools into your workflow is a competitive advantage.

5.     Learn like a sponge. You absorb new domains quickly and without ego. You are comfortable being wrong, asking questions, and updating your understanding in real time.

What We Are Looking For

•     Strong fundamentals in systems programming, algorithms, and data structures

•     Experience building software that has to be fast: you have a track record of caring about performance at a low level

•     Comfort operating in ambiguity: you can take an ill-defined problem, break it down, and ship a working solution

•     Drive and momentum: you are looking for a founding role because you want to move faster than any corporate environment allows

•     Intellectual curiosity about hard technical problems, even in domains outside your current expertise

Nice to Have

•     Experience with high-performance or scientific computing

•     Familiarity with AI/ML infrastructure or numerical methods

•     Prior experience at a high-growth startup or as an early engineer

Compensation

Salary range is $150,000 to $240,000 depending on qualifications and experience. For truly exceptional candidates at the senior or staff level, we are willing to exceed the posted range.

Selected candidates can expect to receive 0.5% to 2% equity. Vesting schedule is a 12-month cliff and 4-year monthly vesting.

We also offer a 401(k) plan and the opportunity to shape the full benefits package as a founding team member.

Make Your Case

We know that the best candidate for this role might not have a traditional background. If your experience doesn't map neatly to the sections above but you believe you belong here, tell us why. We are far more interested in how you think, what you've built, and what drives you than in whether your resume checks every box. Send us a note, a project, a piece of code, or anything that shows us what you're capable of. We, the founders, took unconventional paths to get here, and some of the best engineers we have met did too. 

Research shows that people from underrepresented groups often apply to jobs only when they meet 100% of the listed qualifications. If you believe you have the skills to thrive in this role, we encourage you to apply. You do not need to check every box.

This is a full-time W-2 position based in San Francisco Bay Area. We are unable to sponsor visas other than O-1 at this time.

10x Science, Inc. is an equal opportunity employer. We do not discriminate on the basis of race, color, religion, sex, gender identity or expression, sexual orientation, national origin, age, disability, or veteran status.
