Senior Java/Kotlin Engineer

Nicosia, Nicosia, Cyprus Solidgate Full time

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 skilled Java/Kotlin Engineer to join our Finance Engineering Team — the technical foundation of Solidgate's financial infrastructure.
The mission of this role is to maintain and enhance existing components of our commission calculation and payout system — a business-critical part of the product responsible for fee calculation across acquiring, MoR, and gateway processing, as well as for payout automation and financial reporting.

You'll be directly contributing to the reliability, scalability, and performance of the system that processes millions of transactions every month.

Our services are built with Kotlin and Go, with around 80% of business logic running on Kotlin. No worries if you haven't worked with Kotlin before — you'll get hands-on experience by contributing to real, production-level business tasks from day one.

— Modern technologies: AWS, Kafka, Go, Terraform, Redshift
— Freedom in technical decision-making (team-driven ownership)
— Grow your impact — from hands-on engineering to leading teams as a Staff Engineer or Tech Lead.
