Our Mission and Vision

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.

About the Team and Role

We’re looking for a Kotlin Engineer to join our Finance Engineering team, the financial core of Solidgate — the downstream system that drives the business under the hood.

Our team ensures every dollar a merchant earns lands in their account accurately and on time. We process 18M+ payments every month, generating individually configured fees that influence automated payouts, financial reporting, and the overall merchant experience.

Why it may be your next big move

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.

Why is it the perfect time to join?

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.

• Partnership with Product & Stakeholders. Participate in planning, clarify requirements, explore trade-offs, and help shape solutions in a transparent, constructive way.
• High Standards & Engineering Discipline. Write clean, simple code. Maintain clear service contracts. Ensure backward compatibility. Manage safe, reliable migrations.
• Speed + Quality. Move fast without breaking things — balancing delivery velocity with robust engineering practices.

• JVM Stack — 5+ years of professional experience with JVM technologies, including Kotlin, Spring Boot, and Hibernate.
• Large Databases — Experience working with relational databases exceeding 1TB, optimizing queries for performance.
• Kafka — hands-on work with Kafka and a solid understanding of key consumer metrics and operational considerations.

Mindset & Impact

You don’t just ship code — you own outcomes:

• Product mindset — You think end-to-end and build solutions that solve real user problems.
• Ownership & independence — You drive projects forward and take responsibility for decisions.
• Ability to learn quickly — You pick up new technologies and patterns without waiting for instructions.
