Principal Product Engineer
About Bigspin
Bigspin is the collaboration layer for AI. We replace fragile prompt tinkering with structured, data-driven feedback loops so that domain experts—not just engineers—can shape AI behavior. Our platform helps enterprises build AI systems that actually align with business goals, turning messy experimentation into a reliable, inclusive development process.
Role Overview
We’re looking for a Principal Product Engineer — a seasoned full-stack builder with the product sense and business judgment to help define where Bigspin goes. This is an early, high-impact role: you’ll be one of the first engineers shaping not only the product but also the culture, the way we work with customers, and how we scale.
It’s a mix of engineering rigor, product creativity, and customer engagement. You’ll build, ship, and own major product surfaces end-to-end, partner directly with users to understand their needs (even the unstated ones), and use your business awareness to help steer the product in the right direction.
If you thrive in ambiguity, care deeply about solving real user problems, and have the judgment to be ruthlessly pragmatic without cutting corners—we’d love to talk.
What you'll build + own
- Full-stack ownership: Design, build, and ship features across our stack (Next.js, React/TS, Tailwind, Supabase, AWS, Vercel).
- Product leadership: Partner with design, founders, and customers to spot opportunities, refine workflows, and shape the roadmap.
- Pragmatic execution: Make sound trade-offs—moving fast while building a foundation we can trust.
- Customer engagement: Work directly with users to uncover needs, prototype solutions, and guide them toward high-value outcomes.
What you'll bring
- Strong full-stack engineering experience (React/TS, Next.js, APIs, databases, cloud).
- Proven track record of shipping production applications end-to-end.
- Comfort working directly with customers; clear communicator in technical and strategic conversations.
- Pragmatic mindset with the judgment to balance speed and sustainability.
- Thrives in ambiguity; energized by a startup environment where you’ll wear multiple hats.
- Phenomenal product sense—you think about the “why” and not just the “how.”
Why join us?
At Bigspin, you won’t just be building features—you’ll be helping define the future of AI products and how enterprises adopt them. This is a chance to shoulder real responsibility, have direct impact, and grow alongside the company.
- Competitive salary
- Generous equity: we believe in giving every teammate a real stake
- Collaborative, curious, and high-trust team culture
- Remote-first with Bay Area presence (preferred - we meet roughly once a month in-person for 2 days)
