Senior Product Engineer

Why Polar?

It’s never been easier to build, ship and scale software.
But it’s never been harder to monetize it.
We’re obsessed over solving this to empower the future one-developer unicorns.

These unicorns will be rare but inevitable. Whether in 3, 5, or 10+ years, they also symbolize a broader shift already in motion and accelerating:

• Smaller & smaller teams with…
• Exponential revenue/employee growth
• Focusing fully on their core product and marketing. Delegating & automating everything else that’s boilerplate – be it in their codebase or business operations.

Exceptional billing primitives, APIs, SDKs and abstractions are a crucial foundation, but not enough. They will need a full-fledged platform to oversee, manage and scale their business.

Turning their software into an international business in 6 lines of code.

Join our small, talented and engineering-led team across Europe to shape how future software businesses are built. We focus on shipping at high velocity to serve developers in unlocking their next stage with their business. Everything else is secondary.
