The Opportunity

We are seeking a Staff Full Stack Engineer to join an innovative Startup Studio that is building and scaling AI-native products in highly regulated markets, including healthcare and insurance.

You’ll be working across multiple early-stage portfolio companies—some in stealth mode—on mission-driven platforms that integrate AI, automation, and modern web technologies. This is a hands-on role with high visibility and impact, requiring both technical depth and adaptability. You’ll collaborate closely with design, product, and engineering leads to bring products from concept to launch.

The work spans internal tools, HIPAA-compliant production systems, and greenfield ventures—offering variety, ownership, and opportunities to build reusable components and platform infrastructure that accelerate startup spinouts.

What You’ll Be Doing

• Build and maintain AI-powered, full stack applications across a suite of early-stage products

• Contribute to internal low-code tools, developer workflows, and reusable frameworks

• Work with cross-functional stakeholders to define and deliver scalable technical solutions

• Integrate LLMs and agentic workflows (e.g., LangChain, CrewAI) into real-world products

• Lead architecture decisions, write high-quality code, and promote engineering best practices

• Support secure, compliant deployments in HIPAA-regulated environments using Aptible

• Participate in agile ceremonies, code reviews, technical planning, and mentoring

Must Have

• 8+ years of professional experience in full stack software engineering

• Strong proficiency with TypeScript, Node.js, and React

• Experience building and maintaining HIPAA-compliant systems

• Familiarity with Aptible or similar HIPAA-compliant cloud platforms

• Proficiency with PostgreSQL, Redis, and API design

• Experience with Docker and modern CI/CD pipelines

• Strong automated testing skills (e.g., Jest, Supertest, or similar)

• Ability to work independently in fast-paced, ambiguous environments

• Excellent communication skills and fluent English (written and verbal)
  

Nice to Have

• Experience working with Startup Studios, early-stage startups, or venture-backed teams

• Exposure to agentic AI tools and LLMs (e.g., GPT-4o, Claude, HuggingFace)

• Familiarity with LangChain, DSPy, CrewAI, or similar orchestration frameworks

• Experience with low-code platforms (e.g., Retool, Make.com, Superblocks)

• Knowledge of tools like BullMQ, TypeORM, Zod, Material UI, or ExcelJS

• Background in HealthTech, InsurTech, or other regulated B2B2C domains

• Familiarity with Medicare or pharmacy workflows is a plus
  

What We Offer

• Remote/flexible work environment

• Highly competitive compensation in USD

• Long-term, full-time (40 hours/week) engagement

• Access to exciting AI-powered projects across multiple verticals

• Opportunities for mentorship, learning, and professional growth

• A multicultural, values-driven community of senior engineers
  

Why Join Empirical?

• Care about people first

• Strive to add value always

• Lead with integrity

• Have fun every step of the way
