Senior Go Engineer (Connectivity)

About this role

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 Connectivity team — the team responsible for the user-facing services that serve as the entry point into Solidgate's payment system. It's hard to overstate how critical these services are: every millisecond of load time and every suboptimal step directly affects merchant conversion and company GMV, which means the work demands technical excellence and continuous improvement. The team owns Payment Form and Payment Link (products that let merchants connect to Solidgate and start accepting payments within hours), e-commerce integrations such as adapters for platforms like Shopify, SDKs that make technical integration intuitive and seamless, and Merchant Config, an internal service that stores data critical to payment processing. These products are in a stage of active development, aimed at giving merchants an even more intuitive integration experience along with more room for customization, testing, and support. The strategic goal is to make integrating with Solidgate's payment system the most reliable, extensible, and developer-friendly experience on the market.
