Warszawa, Mazovia, Polska Solidgate Pełny etat
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 Role

We're looking for a Staff Engineer to join our Value-Added Services Stream. You will lead high-impact initiatives that raise reliability, strip away complexity, and unlock delivery speed.

We're reliability-obsessed. We aim for 99.99% uptime, operate at massive scale, and keep turning complex systems into resilient, high-throughput platforms. At Solidgate, engineers don't just ship features — they own org-level impact, drive cross-team change, and build the standards everyone else follows.

You'll work side by side with the Head of Engineering and teams in our Value Added Services stream:

Finance Engineering powering payment processing, reconciliation, and reporting with flawless accuracy

Risk Systems building fraud prevention and risk tools that keep merchants and money safe

Billing running invoicing, subscriptions, and fee management at scale — fast, accurate, reliable

Banking integrating with global partners, routing payments, managing settlements, and keeping liquidity flowing

What you'll be doing
  • Partitioning and sharding databases to keep core payments and other critical systems fast and reliable
  • Scaling and modernizing antifraud systems to stay ahead of the bad actors
  • Building a new billing system and transitioning the subscriptions engine to a B2B model, handling 100,000+ subscriptions monthly
  • Hardening our API Gateway for resilience and DDoS protection
You're a great fit if you have
  • 7+ years of experience in engineering with a strong track record in ownership and leadership roles
  • Proficiency in one of the programming languages: Go, Kotlin, or Python
  • A track record of leading complex, cross-team system deliveries
  • Deep expertise in system design across services and data stores
  • Strong skills in debugging, observability, CI/CD, and cloud fundamentals
  • Clear communication with both technical and business stakeholders
  • Sharp judgment, tech-agnostic mindset, and data-driven decision making
Why Join Solidgate?

High-impact role. You're not inheriting a perfect system — you're building one. Your work will define how we scale.

Great product. We've built a fintech powerhouse that can be quickly scaled. Furthermore, Solidgate's potential isn't just an orchestration player — it's the financial infrastructure for modern Internet businesses with a wide range of products and services, including subscriptions, chargeback management, indirect tax management, and more. And yes — we also hold our own financial licenses in our key regions of operations and have direct memberships with the Schemes.

Massive growth opportunity. Solidgate is scaling rapidly — this role will be a career-defining move.

Top-tier tech team. Work alongside our driving force — a proven, results-driven engineering team that delivers.

There's never been a more exciting time to join Solidgate as a Staff Engineer
