## Job description

Platform Engineering at Polar

Platform engineering at Polar is about building and evolving the systems that power our product – keeping them fast, resilient and simple as we scale. We’re rethinking how billing works for a world of usage-based software, programmable pricing and AI agents – from real-time metering and pricing as code, to more flexible customer identities, giving developers greater control over how they monetize their products.

Polar sits in the critical path of global payments, billing and financial workflows. Reliability and correctness matter deeply, but so does our ability to move quickly.

We’re looking for engineers who enjoy working across infrastructure, backend systems and the application layer – from improving foundational systems and shipping new platform primitives to building the tooling and automation that enable the entire engineering team to move faster.

We don’t believe in building infrastructure for infrastructure’s sake. We value a pragmatic mindset and sensibility in knowing when to introduce new abstractions and when the simplest solution is the right one.

## What you could work on

Depending on your experience and where you can have the greatest impact, this could include:

- Keep Polar reliable at scale: Designing and evolving systems that remain highly available, performant and resilient as traffic and complexity grow – identifying bottlenecks, improving critical paths and designing for graceful failure.
- Evolve our infrastructure: Improving our cloud architecture, infrastructure-as-code and environments – introducing complexity only where it earns its place.
- Make production safe and easy to operate: Improving observability, debugging, deployments and incident response so engineers can ship confidently, understand what’s happening in production and recover quickly when things go wrong.
- Build leverage for engineering: Creating primitives, abstractions and automation that remove operational toil and help the broader engineering team move faster.
- Engineer for financial correctness: Translating financial and regulatory requirements into robust technical systems, with auditability, access control and data integrity built in from the outset.

## What we look for

We’re particularly interested in senior engineers who combine deep systems thinking with exceptional product judgement. People who enjoy solving complex technical problems, take ownership beyond their immediate area and care about building systems that are both robust and easy to work with.

Some of the qualities and experience we value in this area include:

- Strong technical foundations: Backend and systems engineering experience, including distributed systems, cloud infrastructure, and operating production systems at scale. This means that you have built and operated such systems over time to see and understand the pitfalls of the initial decisions
- SQL and data modelling depth: Strong experience with relational databases, data modelling, query optimization and designing for data integrity and performance.
- Pragmatic engineering judgement: The ability to reason through complex technical trade-offs, anticipate failure modes and choose solutions that balance immediate needs with long-term maintainability. You’re comfortable moving across infrastructure, backend and application layers to solve the problems that matter.
- Product-minded: An understanding of how engineering decisions affect the product, with the judgement to balance speed, simplicity and robustness.
- End-to-end owner: A willingness to take responsibility for outcomes, from understanding the problem and designing a solution to shipping, operating and improving it.
- Multiplier: An interest in building abstractions, tooling and automation that make the whole engineering team faster and more effective.
- Security-minded: Treating security, access control and auditability as fundamental engineering considerations rather than afterthoughts.

Experience with payments, billing or financial infrastructure is a strong plus. We also love seeing open-source contributions and side projects.

## Our stack

- Frontend: Typescript (React, Effect)
- Backend: Python (FastAPI, Dramatiq)
- Infrastructure: Postgres, Clickhouse, AWS.

## About Polar

## Company Overview
- **One-liner**: Building the open-source billing layer for the next generation of AI and software products, enabling solo developers and startups to monetize with usage-based, subscription, and credit models.
- **Entity Type**: Private (Seed stage; raised a Seed round led by Accel, amount undisclosed)
- **Headquarters**: Stockholm, Sweden
- **Founded**: 2022
- **Founders**: Not publicly available

## Core Business
- **Primary industry**: Billing & Payments Infrastructure for SaaS and AI products
- **Target customers**: B2B – Solo developers, indie hackers, and early-stage startups (the "future enterprises")
- **Mission or purpose**: To empower solo builders and early-stage startups with a comprehensive monetization platform, bridging product analytics, CRM, and billing.

## Products & Services
- **Polar Platform**: An open-source, all-in-one billing and monetization platform that handles usage-based billing, subscriptions, seats, credits, trials, discounts, cost insights, and merchant of record (global sales tax, compliance, fraud, chargeback protection). Integrates with event ingestion from OpenAI, Anthropic, Vercel AI SDK, S3, and more. Designed to reduce boilerplate code to just four lines.

## Market Standing
- **Valuation/Market Cap**: Not disclosed
- **Key Metric**: Total Funding – Seed round (amount undisclosed) led by Accel, with participation from Abstract Ventures, and angels including Guillermo Rauch (Vercel), Tobi Lütke & Harley Finkelstein (Shopify), Fredrik (Supabase), and others.
- **Notable Investors/Partners**: Accel, Abstract Ventures, Y Combinator (via batch connections), Shopify, Vercel, Supabase, Framer, GitHub
- **Growth Signals**: 
  - 17,000+ signups, 16,000+ X followers, 5,300 GitHub stars, 1,500 Discord members
  - Average revenue growth of 120%+ month-over-month over the past six months (since launching v1.0 in September 2024)
  - Public handbook and open-source codebase attracting community contributions

## Competitive Advantages
- **Open Source**: Built in the open, fostering community trust and contributions; transparent development.
- **Zero Boilerplate**: Extensively reduces custom code for entitlements, license keys, and usage tracking.
- **Usage-Based Billing on Autopilot**: Automatic event ingestion and real-time analytics/billing together in one platform, eliminating the need for separate analytics and billing tools.
- **Merchant of Record**: Handles global sales tax, compliance, fraud, and chargebacks, letting developers focus on product.
- **Developer-First Design**: Purpose-built for solo developers and small teams, with a focus on low-code integration and async workflows.

## Strategic Focus
- Scaling the remote-first team across Europe, particularly in Product & Engineering (Senior Platform Engineer, Senior Product Engineer).
- Investing in developer relations, strategic partnerships across the payments ecosystem, and shipping innovative features for usage-based and agentic payments.
- Continuing to grow the open-source community and drive adoption among AI-native startups.

## Why Work Here
- **Remote-First**: Fully remote, no physical office; async communication, no fixed schedule, high autonomy and ownership.
- **Culture**: Transparent, open-source, async-first, with a strong emphasis on self-organization and self-management. Public handbook and processes.
- **Engineering Focus**: Small team with big ambitions; work on event-driven billing infrastructure, real-time analytics, and open-source contributions.
- **Perks**: Not explicitly listed, but the environment emphasizes freedom, trust, and building in public. Remote across Europe (27 locations, with Stockholm as HQ).
- **Ideal for**: Senior engineers (7+ years) who want high ownership, async collaboration, and to shape the future of software monetization.
