Ever tried building billing systems for modern AI agents and usage-based software? At Polar, we are doing exactly that. We are fundamentally rethinking how global payments and financial workflows operate, and we need talented platform engineers to help us scale. If you love touching everything from low-level infrastructure to high-level application layers without drowning in over-engineered complexity, you will feel right at home here. This is a fully remote role open to engineers anywhere in the world.

Overview

Platform engineering at Polar means owning the foundational systems powering our entire product. Reliability and absolute correctness are non-negotiable since we operate right in the critical path of financial transactions. At the same time, we prize speed and agility. We want pragmatic builders who know precisely when a new abstraction is truly necessary and when keeping things wonderfully simple is the best path forward.

Key Responsibilities

Architect, scale, and evolve the core infrastructure powering real-time metering and programmable pricing.
Build robust backend systems and flexible customer identities that give developers total monetization control.
Develop internal tooling and automation to empower the broader engineering team to ship fast.
Balance high reliability requirements with rapid feature delivery across distributed systems.
Evaluate existing systems proactively to remove bottlenecks before they impact our users.

Requirements

Proven experience working across infrastructure, backend systems, and the application layer.
A pragmatic engineering philosophy focused on shipping business value rather than building infrastructure for its own sake.
Deep appreciation for system correctness, fault tolerance, and security in financial or payment workflows.
Strong communication skills and the ability to thrive in a globally distributed remote environment.

What You'll Gain

The chance to define the financial rails for the next generation of software and AI agents.
Complete location independence through our fully remote, worldwide work model.
Autonomy to make critical technical decisions and shape our product architecture from the ground up.
Collaboration with a lean, highly talented team where your code has immediate global impact.
