    Job description

    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 Billing team and take ownership of the Taxes module — a core part of our billing system responsible for tax calculation and reporting across multiple locations.

    The product has already moved beyond MVP and is actively used by customers. The foundational logic is in place, demand is high, and the next step is scaling functionality and reliability.

    This role is exciting because you’re not maintaining legacy code — you’re building and shaping a critical system almost from scratch.
    You will have a clear path to Lead: full ownership of the Taxes direction, architectural decisions, and growing a team around it.

    Your team — Product Owner, 1 Senior Engineer, 1 Junior Engineer, Automation QA, and Tax Manager.

    Explore our technology stack ➡️ here.

    What you’ll own

    Your focus will be on:

    • building tax calculation and reporting logic

    • integrating third-party tax providers

    • improving system resilience and uptime

    • making architectural decisions and setting technical direction

    • mentoring engineers as the team grows

    In the first months, you’ll deliver key tax functionality and lay a solid foundation for future product and team growth.

    We rely on automated testing over manual QA — unit, integration, functional, and e2e tests are a core part of how we ship and scale safely.

    You’re a great fit if you have

    • 6+ years of backend engineering experience (Go/PHP/Kotlin/Java/Python)

    • Strong understanding of high-load system design

    • Solid experience with PostgreSQL

    • Experience with queues or streams

    • Strong testing culture: unit, integration, functional, e2e

    • Proactive, independent, result-oriented mindset

    Nice to have

    • Kafka

    • AWS services

    • CI/CD pipelines

    • Fintech / payments / financial domain experience

    • Understanding of VAT, GST, Sales Tax

    • Experience managing teams
