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, which builds the finance system. It's essentially a highly powerful calculator that helps businesses run smoothly. The goal is simple: ensure that every dollar merchants and Solidgate earn ends up in their accounts correctly and on time.

We process over 18 million payments every month, generating fees based on each individual's specific settings. This affects automated payouts and financial reports.

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.

Explore our technology stack ➡️ here (https://solidgate-tech.github.io/)

What You’ll Drive

• Architecture & Implementation. Design and implement end-to-end solutions for commissions, agreements, financial reporting, and other features for merchants and internal users.
• Extreme Ownership. Take responsibility for outcomes — not just tasks — ensuring quality, clarity, and effectiveness across the project lifecycle.
• Competence Growth & Contribution. Actively share knowledge, initiate improvements, and drive both product and process enhancements to completion.
• 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.

   

What We Pay Attention To:
Technical Mastery

You know your way under the hood:

• 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.
• High standards & accountability — You deliver reliable systems and hold yourself to exceptional quality.
  
   

The Points That Make You Stand Out

• Experience with Kafka Streams, SQS, S3, Redshift

• Background in Fintech, especially in payments, billing, or financial processing

   

Why Solidgate?

High-impact role. You’re not inheriting a perfect system — you’re building one.

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

Modern engineering culture. TBDs, code reviews, solid testing practices, metrics, alerts, and fully automated CI/CD.

Top-tier tech team. Work alongside our driving force — a proven, results-driven engineering team that delivers. We’re also early adopters of cutting-edge fraud and chargeback prevention technologies from the Schemes.

Great product. We’ve built a fintech powerhouse that scales fast. Solidgate isn’t just an orchestration player — it’s the financial infrastructure for modern Internet businesses. From subscriptions to chargeback management, fraud prevention, and indirect tax — we’ve got it covered. We hold financial licenses in key regions and are a direct Visa & Mastercard partner and sub-reseller (top 5 globally).
