About Us:
We are on a mission to shift the paradigm in the war on cancer from reaction to early detection and prevention. The company’s team of doctors, AI engineers, and biostatisticians have built a risk engine capable of computing the personal lifetime cancer risk for any individual - think a “credit score” for cancer risk - based on their unique genetic and lifestyle risk factors. By calculating cancer risk at an n-of-1 level and translating specific risk factors into actionable recommendations for lifestyle changes and diagnostic screening, we will make it possible for anyone to know their risk - and take control.

Beyond cancer, our team is building risk models for heart disease, metabolic syndromes, and neurodegenerative disease - chronic conditions that collectively kill over 1.5 million Americans annually and each represent $1+ trillion markets. The company is backed by founding investors, who have co-founded and scaled their previous company using the same D2C membership model to over 1.5 million paid members, $500 million in annual revenue, and a $1.4 billion valuation, representing a >100x return for early investors.

Position Overview:
As one of our first engineers, you'll own core product development and help shape our technical foundation. We're looking for a builder who thrives in early-stage environments and isn't afraid to move fast and iterate. You'll have significant autonomy to make decisions and implement solutions across our entire stack - from React frontends to Python backends to AWS infrastructure.

What You'll Do:

• Drive end-to-end product development using React, TypeScript, Nest.js, Python, FastAPI, and PostgreSQL
• Design and implement scalable architectures on AWS that can handle rapid growth
• Build and maintain our cloud infrastructure and CI/CD pipelines using Terraform and GitHub Actions
• Instrument and monitor our applications with Datadog
• Respond to production incidents with urgency and own on-call responsibilities
• Obsess over user experience and proactively identify and fix issues
• Make pragmatic technical decisions that balance speed and quality

What We're Looking For:

• 5+ years of full-stack engineering experience with a proven track record of shipping high-quality products
• Deep expertise in our core stack: Python (FastAPI), TypeScript (Nest.js), React, Postgres, and AWS
• Experience with DevOps practices including CI/CD (Github Actions), infrastructure as code (Terraform), and containerization (Docker)
• Experience monitoring and optimizing web applications using APM tools such as Datadog
• Ability to disagree and commit - we value strong opinions weakly held
• Self-driven work style suited for a remote-first environment
• Bias toward action and getting things done over perfection
• Strong command of English (B2+)

Bonus Points:

• Experience in healthtech or with HIPAA compliance
• Early-stage startup experience
• Background in AI/ML, data engineering, or data analytics

Why us:

• Ownership: Shape the technical direction of a venture-backed startup tackling massive healthcare challenges
• Impact: Build products that directly improve people's lives through early disease detection and prevention
• Growth: Join early and grow with the company as we scale
• Autonomy: Work remotely with the freedom to make decisions and drive results

Candidate location: Latin America, Europe
