Senior Product Engineer

It's never been easier to build, ship and scale software.

But it's never been harder to monetize it.

Modern startups look fundamentally different than prior generations:

• Smaller teams

• Exponential revenue growth relative to headcount

• Higher variability in costs (LLMs) requiring more frequent pricing iterations

• Laser focused on product development and distribution

• Delegating and automating everything that is boilerplate – be it in their codebase or business operations.

Exceptional billing primitives, APIs and SDKs are essential, but delightful integration is not enough.

Startups need a billing platform designed for their speed of iteration. Combining billing and analytics in one platform to offer customer- and feature unit economics in real-time. Offering built-in pricing and cost insights, simulations and optimizations while simultaneously handling international compliance, tax management, fraud prevention and more.

That's Polar. We're building the next standard for applied AI startups.

Join our small, talented and engineering-led team across Europe as we build the infrastructure powering the next generation of software companies.

We focus on shipping at high velocity to serve startup founders scale their businesses. Everything else is secondary.

Fullstack engineerings with a strong product sense and taste. As we grow, we'll gradually move towards more specialized roles between backend vs. frontend vs. product engineering. Therefore, we ask about your main strength in the application to ensure we maintain a strong & balanced team across the spectrum.

• Frontend: React & Next.js with Tailwind CSS, Shadcn, TanStack Router and more.

• Backend: Python (FastAPI), Postgres, Redis, Dramatiq.

• Cloud: Vercel, Render & AWS.

Always subject to change as we scale and new technologies emerge.

We don't have a lot of meetings, red tape or code reviews. We celebrate and optimize our organisation for shipping high-quality software fast – each engineer deploys countless times a day. So you'll be given a lot of agency and autonomy to move fast towards our mission and serving our developer community.
