Part-time Support 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.
Role & responsibilities: What you will do
We’re hiring a Part-time Support Engineer to help provide exceptional support to our merchants. This role is ideal for someone who wants to work part-time alongside studies or other commitments, with a developer background who enjoys problem-solving, working directly with customers and thinking in systems - not just tickets. You’ll operate as an extension of the core team during off-hours, ensuring that merchants get unblocked quickly while continuously improving how support is delivered.
You won’t just respond to issues, you’ll help us scale support through better tooling, AI, and feedback loops into the product.
Support merchant experience - Own developer interactions across support channels (tickets and GitHub), delivering fast, clear, and high-quality responses that unblock merchants while identifying gaps in docs and opportunities to improve self-serve.
Account reviews & risk awareness - Operate and evolve automated account review workflows, applying judgement on edge cases and improving how we balance speed, compliance, and merchant experience.
Triage, debugging & resolution - Diagnose issues end-to-end, reproduce bugs, and route effectively (docs, fixes, or escalation), while identifying patterns beyond individual tickets.
AI-first support & operational leverage - Use AI, scripts, and internal tooling to improve response quality, build lightweight automations, and continuously evolve our knowledge base to scale support beyond linear efforts.
Feedback loops into product - Turn recurring friction and real-time customer interactions into structured insights that drive improvements across product, APIs, documentation, and internal systems.
What we’re looking for
Operating Mindset
Strong merchant empathy - you care deeply about unblocking users and creating a great merchant experience.
You treat support as a core part of the product - spotting recurring issues, closing documentation gaps, and building repeatable solutions that improve the overall experience.
AI-first and systems thinking - you approach support as a system to continuously improve, identifying patterns, building leverage (automation, tooling), and reducing manual work.
Feedback loop mindset - you naturally translate support patterns into structured insights that drive product, API, and documentation improvements.
High ownership and autonomy - comfortable operating independently in a small team, especially during off-hours, while making sound judgement calls.
Strong communication and handover discipline - you document context, decisions, and open threads clearly, enabling seamless transitions across shifts and ensuring nothing falls through the cracks.
Technical Skills
Developer background with the ability to debug real-world integration issues.
Strong SQL skills and ability to reason about data when troubleshooting.
Comfortable in Linux/Unix environments and using command-line tools.
Familiarity with GitHub (Issues, Discussions) and developer workflows.
Ability to clearly explain technical concepts.
Experience
~2 years of experience across engineering, support, or similar technical roles.
Experience working directly with customers or developers in a product or support-facing capacity.
Demonstrated ability to solve ambiguous problems and go beyond one-off fixes.
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 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.
