Software Engineer III, Backend - Core Domain

About us

Traditional banking has never really given you control over your financial life. Satispay exists to change that: to empower people through finance.

That means making financial services easy and accessible for over 6.5M users. We started with payments, then benefits, investing, cards... and we’re not done. Not even close.

We follow the same logic every time: find a real problem, solve it properly, then look for the next one. The destination? To build the most loved financial platform in the world.

If you own outcomes rather than tasks, stay close to what users need, and refuse to wait for someone else to fix what's broken — you'll find people here who work exactly in the same way. And together, you'll build something worth being proud of.

What you'll be doing

As our Software Engineer, Backend in the Core Team, you'll play an important role in building and maintaining the backbone of our payment platform, contributing to the technical quality and delivery of robust systems that support multiple services and product teams across the company.

Here's what that looks like in practice:

• Contribute to core platform domains - Help build, maintain, and scale our most sensitive systems—such as the Transaction Ledger, Identity & Access Management (IAM), or Payment Orchestration.

• Develop risk & financial engines - Implement and optimise services dedicated to bank integrations, credit risk, and real-time fraud detection to protect our "source of truth."

• Collaborate on technical solutions - Participate in technical analysis for new projects, engage in technical discussions, and contribute to high-quality documentation (Smart Papers).

• Drive engineering quality - Ensure technical excellence by writing clean code, implementing rigorous testing strategies, and executing safe rollouts while resolving technical blockers.

• Work in an AI-powered environment - Leverage AI tools daily to write and optimise code, speed up root cause analysis, and generate documentation to raise engineering efficiency.

• Grow and collaborate - Work with senior engineers to elevate your architectural skills while supporting junior team members in adopting best practices for secure and reliable development.

Who we're looking for

This role needs someone who is a problem-solver, loves teamwork, and gets things done with curiosity and readiness for real ownership.

• Experience - At least 3 years of experience as a Backend Engineer, with a proven track record of building and maintaining scalable microservices.

• Technical Foundations - Deep expertise in Java and Spring Boot, with a solid understanding of distributed systems and external dependencies like banking APIs.

• Cloud Awareness - Good exposure to cloud environments (AWS is a plus) and relational databases (PostgreSQL).

• Reliability Mindset - Deep care for system health, data integrity, and clean business logic, with comfort in debugging complex service issues.

• Communication - Ability to communicate technical concepts clearly and collaborate effectively with both technical and non-technical peers.

• Passion and language proficiency - Passionate about FinTech and fluent in English.

Don't worry if you don't tick every box. We believe in the power of different viewpoints and strengths. Your unique perspective is important as we build something special: if you're passionate and can make a difference, we truly encourage you to apply.
