# Senior Product Engineer at Polar

- **Company:** Polar
- **Location:** Europe
- **Employment:** full-time
- **Work type:** remote
- **Posted:** 2025-09-05
- **Last confirmed live:** 2026-09-10

## Job description

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.

Product Engineering at Polar 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.

## Our Stack

- 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.

## Role & responsibilities

We’re hiring exceptional Senior Product Engineers to join our growing remote-first team in Europe. You'll work across our entire stack to ship innovative features, enhancements and delights; obsessing over the developer experience and empowering them to scale their businesses. You're very comfortable jumping between frontend, backend, and infrastructure to autonomously identify, build, ship and scale features. 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.

- Ship daily towards building the best monetization platform for developers in the world.
- Design, build, and ship features, enhancements and delights end-to-end – jumping between frontend, backend, and infrastructure.
- Collaborate with the team on architecture design, best practices, and ensuring high-quality code across our stack.
- Continuously improve the quality of services and the overall developer experience.
- Engage frequently with our developer community to identify pain points and solve them.

## What we're looking for

- 7+ years of experience building, shipping and scaling high-quality software.
- You ship fast and can solve any problem thrown at you end-to-end.
- Strong proficiency with our stack or a variety of similar programming languages and ability + desire to quickly learn and pickup new tools.
- Strong problem-solving abilities with an eye for developer experience.
- Experience with cloud infrastructure and multi-cloud environments.
- Excellent collaboration skills - comfortable working closely with a small, high-performing team. It's a startup so we all have to lean-in across the board to.
- You care deeply about your craft - be it delightful animations, thoughtful edge-case handling, developer experience or performance optimizations.
- (Bonus) You're an ex-founder/startup CTO, open source maintainer or indie hacker.
- (Bonus) Experience working with payments, billing, or developer tools.

## What we offer

- Meaningful ownership: Small team & large surface area. You’ll directly influence how the company and platform scale.
- Product-driven culture: We build to empower the next generation of software companies - and operate with the same builder mindset internally.
- Competitive compensation: Salary and equity aligned with the impact of the role.
- Exceptional team: Work with highly talented team members distributed across Europe.
- Remote-first environment: Work from anywhere in Europe, with a home office setup budget available.
- Annual team offsites: As the team is spread across Europe, we gather in person at least once a year to collaborate, plan, and spend time.
- Health Benefits: Comprehensive health coverage to support you and your family.
- Parental leave: Paid parental leave aligned with the standards and regulations of your local jurisdiction.
