Sales Engineer

Ataraxis is a clinical AI research lab working at the intersection of multi-modal AI and precision medicine. Our goal is to make disease predictable. To accomplish this, we develop new AI methods that predict patient outcomes and treatment response, and build clinical tools to assist physicians in selecting the most optimal treatments for their patients.

Our AI research lab discovers and develops methods to recognize patterns and predict outcomes across complex, multi-modal clinical data. This spans our causality (Ataraxis™ Tau), foundation model (Falcon and Kestrel for digital pathology), and survival analysis research.

Our first clinical products, such as Ataraxis™ Breast for breast cancer, already help patients get the most appropriate treatment across the best academic institutions and community clinics worldwide.

At Ataraxis, you will have a unique opportunity to shape not only the future of our company, but also the future of healthcare. You will join an exceptional team at the forefront of clinical AI research and deployment. Our advisors include AI pioneers such as our founding advisor, Yann LeCun, and distinguished oncologists from top cancer research institutions, all united by the mission to redefine precision medicine.

Ataraxis has raised over $24 million in funding, including a $20 million Series A led by top venture capital funds such as Thiel Capital/Founders Fund (OpenAI, SpaceX, Palantir), Obvious Ventures (AMI Labs, Inceptive, Radical Numerics, Recursion), and AIX Ventures (Hugging Face, Perplexity).

We are an company with a flat organizational structure, where every team member is empowered to actively contribute. Leadership roles are earned by those who demonstrate initiative and consistently deliver exceptional results. Strong work ethic and the ability to prioritize ruthlessly are essential.

This is a role for an end-to-end/generalist software engineer with lots of ownership. You will be leading situations that require speaking with Ataraxis's customers and partners, and working with them directly on integrations and developing internal and external products related to commercialization. Internally, you will be working with sales team and other people in the commercial organization.

You need to be comfortable moving between product code and ML infrastructure. You will be maintaining and building our several internal services, such as physician web portal and order service.

• Product-obsessed builder: You're never satisfied with "good enough"—you relentlessly spot opportunities to improve the product and move fast to ship them, knowing that done and iterating beats perfect and waiting.

• AI-native: You're comfortable using latest AI tools (e.g., Cursor, Claude Code) to quickly build, refine, and document your code.

• Strong external communicator: You can represent the product and company confidently to customers, partners, and the outside world—translating technical work into clear, compelling narratives.

• Sense of style: You appreciate polished, professional UIs, enjoy collaborating closely with designers, and understand that great UX is integral to great products.

• Creative thinker: You thrive in environments requiring innovation and aren't limited by past experience.

• Self-directed leader: You take ownership, set your own agenda, and move with urgency. You don't need a roadmap handed to you. You identify what matters and rally others around it.

• Effective collaborator: You keep teammates informed, surface blockers early, and turn around feedback rapidly, making it easy for those around you to do their best work.

• Frontend

  • Strong TypeScript and React (we run React 19 /Next.js 15, App Router)

  • Tailwind CSS, component-driven UI, and modern testing with Jest+ React Testing Library and Playwright for E2E

  • Bonus: data viz (Recharts), rich-text (Tiptap), or medical image viewers (OpenSeaDragon)

• Backend

  • Strong Python, with production experience in Flask (or similar) and SQLAlchemy/PostgreSQL

  • Database schema migrations (Alembic / Flask-Migrate)

  • Designing and consuming REST APIs; integrating third-party services

  • Async/background job processing (Google Cloud Tasks)

• Cloud & DevOps

  • Hands-on Google Cloud Platform: Cloud SQL, Cloud Storage (GCS), Cloud Run, Cloud Tasks

  • Docker and CI/CD with GitHub Actions; tag-based semantic-versioned releases

  • Comfort with Vercel (portal) and serverless GPU deploys (Modal)

• Testing & quality

  • A genuine testing discipline—pytest, Jest, and Playwright are first-class here, and our work feeds a regulated requirements-traceability process
