Senior Java Backend Engineer

About our client

A leading international fintech company operating payment systems used daily by millions of customers and businesses globally. Their infrastructure handles real-time transactions across continents — at genuine scale.

The team is technically serious: real architecture discussions, no ticket factory. They're currently expanding to accelerate the next wave of product development — including modernization of core payment flows and exploration of blockchain and digital settlement infrastructure.

Job description

Role / Mission

You'll join a cross-functional Scrum team working on both new product features and the ongoing modernization of an existing payment platform. The team includes architects, analysts, developers, QA, and a Scrum Master — you'll collaborate across all of them.

You report to the Engineering Manager. Architecture decisions are made collaboratively within the team — you'll be part of design discussions from the start, not handed specs to implement.

In 12 months: you own at least one major component of the payment infrastructure. The codebase is cleaner, microservice boundaries are clearer, and the team ships features faster because you helped make that happen.

Key Responsibilities

— Build new product features and drive modernization of existing payment application components
— Participate in requirement grooming and planning — understand the business domain, not just the tickets
— Evaluate technical solutions, identify risks, and contribute to architecture decisions during design phases
— Break down work, estimate scope, and take ownership of sprint commitments
— Do pull requests — review code (yours and others') with focus on quality and long-term maintainability
— Work with complex business logic: payment workflows, distributed transactions, eventual consistency
— Collaborate with mobile developers (iOS/Android) on API contracts and integration points
— Contribute to CI/CD practices and automated testing improvements

This is not a helpdesk role. Not a shift-based rotation. You write code that powers real financial flows — and you'll know why every line matters.

Operating Model

Remote-first. Occasional visits to the Prague office for team sync and planning — not mandatory, but available. Flexible working hours with a daily standup to align the team.

Working language: Czech or Slovak internally (English for documentation and cross-team communication). Scrum-based team rhythm, async-friendly for deep work.

Requirements

Core Requirements

— Java — 3+ years of commercial experience
— Spring Boot and microservice architecture — not just awareness, actual hands-on work
— NoSQL databases (MongoDB or similar) and cloud platforms (AWS or equivalent)
— Apache Camel or WebFlux — experience with at least one

Profile

— Czech or Slovak — conversational level required; English for written communication
— Independent — you don't wait to be told what to do next
— Communicative — you can explain a technical decision to someone who isn't an engineer
— Proactive approach to technical design, not just implementation
— Comfortable in cross-functional teams with non-engineering stakeholders

Nice to Have

— AI Agents experience (development or integration)
— AWS certifications or deep AWS knowledge (EKS, Lambda, Atlas)
— FinTech or payment systems background
— Jira proficiency for Epic and User Story management

These are genuine advantages — not hard filters. If the core requirements fit, reach out.
