Principle Software Engineer

Location: Hybrid 3x / week in Oakland, CA

The Opportunity

This is a foundational, first-principal engineering hire reporting directly to a newly appointed CTO. You’ll play a critical role in shaping the next generation of the platform—owning architecture, building systems from scratch, and helping define the technical vision.

The environment is intentionally lean and highly technical, with a strong emphasis on hands-on building, experimentation, and rapid validation of new ideas.

What You’ll Do

• Design and build end-to-end systems from concept through production
• Develop agentic GenAI workflows leveraging internal and domain-specific datasets
• Build workflow orchestration systems for AI-driven use cases
• Contribute to marketing and growth engineering systems (e.g., personalization, engagement, email delivery)
• Develop commercial AI models to better understand user behavior and drive platform outcomes
• Collaborate closely with product, leadership, and a distributed engineering team (Europe-based)

What We’re Looking For

• 10+ years of software engineering experience with a strong builder mindset
• Proven experience owning systems end-to-end in early-stage or high-growth environments
• Strong backend development experience with Python (Django preferred)
• Frontend experience with React
• Cloud expertise (AWS) and experience with PostgreSQL or similar databases
• Exposure to AI/ML systems, ideally including LLMs or agent-based architectures
• Ability to operate autonomously, go deep technically, and articulate decisions clearly

Nice to Have:

• Experience working with healthcare or regulated data environments
• Background in building knowledge systems or data-heavy platforms

Why This Role

• Direct partnership with the CTO and influence over technical direction
• Opportunity to be a founding-level engineer in a high-impact domain
• Build from zero → one, then scale alongside the business
• Profitable company with strong growth (not dependent on external funding cycles)
• Highly technical, low-ego, builder-first culture

Compensation

• Base: $280K – $350K
• Performance bonus
• Meaningful equity

Interview Process

• Hiring Manager Screen
• Values Interview (Zoom)
• Onsite (technical + cross-functional)
• Executive Interview

Timeline: ~3–4 weeks
