$280K-$350K BASE + BONUS + EQUITY
HYBRID ROLE - BAY AREA (3 DAYS/WEEK IN OFFICE)
Are you a hands-on builder who loves designing systems end-to-end - from architecture to production - and bringing AI-powered ideas to life? This is a rare opportunity to join a profitable, high-growth healthcare technology company as a founding engineer on a small, senior team working directly with the CTO.
THE COMPANY
This profitable and fast-growing technology company is redefining how professionals in a specialized field learn, collaborate, and access critical information. Backed by strong revenue growth and a proven business model, they're investing heavily in AI-driven solutions that enhance discovery, personalization, and user engagement.
You'll join a small, high-performing engineering team that values autonomy, innovation, and craftsmanship - working on products that make a measurable impact in a real-world, mission-driven domain.
THE ROLE
As Principal Software Engineer, you'll lead the next evolution of the platform's architecture and AI capabilities. This is both a builder and architect role - ideal for someone who enjoys zooming out to define systems and zooming in to code prototypes and production features.
You will:
- Design and implement scalable backend and frontend systems powering global medical education.
- Build and deploy GenAI and Agentic AI workflows that personalize learning and discovery for doctors.
- Collaborate with data, AI, and product teams to create intelligent features such as search, summarization, and content recommendations.
- Modernize platform architecture (Python/Django, React, AWS).
- Prototype new product ideas, validate them with live customers, and iterate quickly.
- Mentor engineers and help define best practices across teams.
- 6+ years of software engineering experience, ideally at Principal, Staff, or Architect level.
- Expertise in Python/Django and strong React/JavaScript (TypeScript) skills.
- Deep understanding of AWS architecture and distributed systems.
- Experience building AI-enabled or data-driven applications (LLMs, agents, personalization).
- A "builder mindset" - hands-on, fast-moving, and comfortable working in ambiguity.
- Bonus: exposure to medical or healthcare data.
- $280k-$350k base + bonus + equity grant
- Hybrid role
- Direct collaboration with the CTO and senior engineering leadership
- Opportunity to shape the future of an AI-driven healthcare platform impacting millions
