Founding Product Engineer

About the job
Location: Switzerland · Type: Full-time · Equity

About us
We’re building an AI-powered B2B SaaS platform helping FMCG brands manage Key Accounts, activations, stores, execution, trade budgets and market intelligence in one workspace.

We’re a small, ambitious founding team building from 0 → scale. We’re looking for someone who wants real ownership, meaningful equity and a seat at the table.

The role
As our Founding Product Engineer, you’ll work directly with the founders and play a central role in shaping, building and shipping the product. You do not start from scratch - the basic of the product is built and you would take it to the next level.

This is not a traditional Product Manager or Software Engineer role. You’ll combine product thinking, business understanding and hands-on engineering.

You will:
Work directly with the founders to identify the highest-value customer problems
Turn problems into simple, scalable product solutions
Own features end-to-end: problem → specification → build → launch → iteration
Build and ship production features yourself
Use AI-native development workflows to move extremely fast
Work closely with our engineering team and raise the product and technical quality bar
Help shape our product architecture and technical direction
Think commercially: Would customers pay for this? Does it solve a real problem? Can it scale?
Speak directly with customers when needed and translate feedback into product decisions

Technical background
You should be a strong full-stack Next.js developer with excellent product instincts.
Strong Next.js, React and TypeScript
Comfortable building REST APIs / server actions
Solid Postgres and ORM experience
Understanding of authentication and application architecture
Comfortable with Git workflows and Vercel deployment
Experience integrating third-party APIs and AI services
Highly proficient with AI coding tools and modern AI development workflows
Nice to have: Supabase, Tailwind, CI/CD

You don't need to know every technology perfectly. What matters is that you can learn fast, use AI effectively and turn an idea into a working product quickly.

The person we're looking for
You are a builder, not just a manager
You have strong technical fundamentals and excellent product judgment
You move fast without sacrificing good engineering
You naturally think about customers, business models and scalability
You are comfortable with ambiguity and taking ownership
You don't wait for perfectly defined tickets — you help define what should be built
You want to work closely with founders and have influence over major decisions
You are excited by the idea of building something that could become a large, category-defining B2B SaaS company

What we offer
Equity with real upside
A genuine seat at the table alongside the founders
Significant ownership over product and technical direction
High autonomy and very little bureaucracy
The opportunity to build an AI-native SaaS company from the ground up
A fast-moving environment where what you ship directly impacts the company

Important
You must be based in Switzerland and able to work closely with the founding team (sometimes in person in our Lucerne office).
