At Solidgate, our mission is clear: to empower outstanding entrepreneurs to build exceptional internet companies. We exist to fuel the builders — the ones shaping the digital economy — with the financial infrastructure they deserve. To achieve that, we’re on a bold path: to become the #1 payments orchestration platform in the world.

We’re looking for a Kotlin Engineer to join our Finance Engineering team, which builds the finance system. It’s essentially a highly powerful calculator that helps businesses run smoothly. The goal is simple: ensure that every dollar merchants and Solidgate earn ends up in their accounts correctly and on time.

We process over 18 million payments every month, generating fees based on each individual’s specific settings. This affects automated payouts and financial reports.

Impactful work. Build a mission-critical platform that directly affects the products you use every day. We’re defining what future Solidgate financial contracts will look like.

Collaboration with experts. Work alongside engineers who built systems at Amazon, Revolut, Wix, and other world-class products.

Solve complex challenges. Design solutions for sophisticated financial logic while optimizing for reliability, observability, throughput, and scalability.

Autonomy & ownership. Own your work end-to-end — from design to deployment — and see the direct business impact of your decisions.

AI-assisted engineering: We invest in developer productivity by fully covering tools like GitHub Copilot, Windsurf/Cursor, and Coderabbit. You’ll write less boilerplate, ship faster, and focus on solving real problems — not fighting with repetitive code.

We’re building a next-generation financial system from scratch — not refactoring legacy code.

We’re standardizing fee calculation logic, making configuration transparent and modular, and laying the groundwork for new financial modules such as pricing, billing, ledger, and more.
