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.
We believe the future of payments is shaped by people who think big, take ownership, and bring curiosity and drive to everything they do. That's exactly the kind of teammates we want on board.
Solidgate is part of Endeavor — a global community of the world's most impactful entrepreneurs. We're proud to be the first payment orchestrator from Europe to join — and to share our expertise within a network of outstanding global companies.
About the Team and Role
You'll join the Core team — the team responsible for the services that sit at the heart of Solidgate's payment processing. Core services define what a payment is, integrate with numerous internal services for correct routing, run antifraud checks, and process payments through providers, covering card payments as well as Apple Pay and Google Pay. This is the critical path for every payment on the platform, so the team's work directly defines the reliability and speed of the whole system.
The team is actively growing new functionality, supporting existing services, working down technical debt, and maintaining an SLO of 99.99%+ across all of its services. The stack is built around high-load, low-latency requirements: a microservices architecture with Kotlin as the primary language, Protobuf RPC over Buf/Connect, PostgreSQL as the main database, and Kafka for asynchronous processing, with fully automated production deployments and an advanced monitoring and observability setup. Infrastructure is continuously improved by a dedicated platform team, with IaC ensuring transparent, reproducible, and scalable management.
Your team — Product Manager, Tech Lead (Backend), three Backend Software Engineers (Senior), one Frontend Software Engineer (Middle), AQA Engineer, and System Analyst.
