About the Role
We’re hiring a Senior Product Engineer (Full-Stack) to own complex, user-facing systems end-to-end. This is not a single-layer role — you’ll work across frontend UX, backend systems, APIs, and data models, making pragmatic trade-offs between product velocity, scalability, and long-term maintainability.
You’ll partner closely with the founders to design, build, and evolve core AI-powered workflows, acting as both a strong technical owner and a product thinker.
What You’ll Do
Own product features from concept and UX through backend systems and production launch
Design scalable backend architectures, APIs, async pipelines, and AI inference workflows
Lead system design with a focus on performance, reliability, and extensibility
Design clean, scalable data models across SQL and NoSQL systems
Build polished frontend experiences using React / Next.js
Make and clearly communicate technical trade-offs
Collaborate closely with Product, Design, and GTM
Mentor engineers and raise the overall engineering bar
Influence architecture, tooling, and engineering best practices
What We’re Looking For
Core
Strong full-stack experience shipping production systems at scale
Ability to independently design and ship end-to-end features
Strong system design and data modeling skills
Experience with relational and NoSQL databases (e.g. PostgreSQL, Redis, Firestore)
Backend experience with Node.js and/or Python
Frontend experience with React / Next.js
High product intuition and comfort operating in ambiguity
Nice to Have
Experience with AI-powered or data-heavy products
Cloud-native architecture experience (GCP, serverless, containers)
Startup experience or ownership of large product surfaces
Tech Stack
React / Next.js · Node.js · TypeScript · Python · GCP · Cloud Run · Modal · Firebase · Redis · Upstash
Compensation
~$300k total compensation (base salary, bonus, equity)
Meaningful equity ownership
High-autonomy, high-growth environment
Work Setup
Bay Area preferred (hybrid allowed)
North America remote considered
Visa sponsorship available
What Success Looks Like in 3–6 Months
Shipped multiple features users love
Launched at least one AI-powered user flow end-to-end
Built tight feedback loops with founders, design, and real users
Proactively shaping product and engineering direction
If you're excited about building magical AI experiences and owning real product impact from day one, we'd love to talk.
