Senior Platform Engineer

WHY POLAR?

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.
