What you will do
As a Senior Product Engineer you will be the CTO's right hand managing the project portfolio, shaping the roadmap with founders, and shipping production code, often all in the same day.
Scope features, define requirements, deliver end-to-end, run QA, and iterate based on real customer feedback.
Unblock engineers technically and set direction across the team without stepping away from the codebase.
Talk directly to customers and partners to understand problems before writing a line of code.
Contribute to roadmap decisions alongside the founders deciding what to build and why.
Work across the full stack, from database design and backend services to frontend UX and infrastructure.
Who are you
You have founder DNA you've started a company, been an early employee at a high-growth startup, or worn multiple hats in a single role across engineering, product, and customer work.
You've owned products end-to-end: scoping, definition, delivery, QA, and iteration based on real usage. You think in customer problems before features.
You're a full-stack engineer with 7–10 years of experience, actively coding in your current role in TypeScript and Node.js. If you haven't written production code in the past few years, this isn't the right role.
You've worked directly with customers alongside technical work and can manage stakeholders across engineering, business, and external partners.
You're comfortable with ambiguity and move fast. You're first to roll up your sleeves, not the last to ship.
Consulting background, open-source contributions, writing, or talks are a genuine plus.
Tech stack
We are problem solvers first and are not fixed with any specific technologies. We aspire to build the most lovable and exciting products, regardless of what technology powers it.
Our current stack is:
Frontend: Next.js, React, Tailwind, Next.js
