We're a movement empowering millions of people, driven by a shared purpose to tackle big challenges. And we're just getting started.
You will be joining the Business Team — the team that helps businesses improve their finances with Satispay. We own the financial backbone: fees, payouts, invoicing, compliance, and everything in between. If a business relies on Satispay to get paid correctly and on time, our team make it happen.
We move quickly, think boldly, and trust each other to challenge the norm, learning and growing as we go. If you're looking for more than just your next job – if you want to build something impactful with a talented team – you're in the right place.
What you’ll be doing
As a Software Engineer, Backend in the Core Team, you’ll play an important role in building and maintaining the backbone of our payment platform. You will be a key contributor to the technical quality and delivery of robust systems that support multiple services and product teams across the company. Here’s what your day-to-day will look like:
Contribute to core platform domains: You will help build, maintain, and scale our most sensitive systems—such as the Transaction Ledger, Identity & Access Management (IAM), or Payment Orchestration. You’ll work closely with senior engineers to ensure these engines remain high-performant, secure, and "functional" for our product teams.
Develop risk & financial engines: You will implement and optimise services dedicated to bank integrations, credit risk, and real-time fraud detection. You'll write the robust logic that protects our "source of truth" and secures Satispay’s financial ecosystem.
Collaborate on technical solutions: You will participate in technical analysis for new projects and feature developments. You'll engage in technical discussions and contribute to high-quality documentation (Smart Papers) to ensure your implementations are clear, robust, and aligned with team goals.
Drive engineering quality: You will ensure technical excellence by writing clean, maintainable code, implementing rigorous testing strategies, and executing safe rollouts. You’ll work with your team to troubleshoot and resolve technical blockers, promoting a culture of simplicity in the codebase.
Work in an AI-powered environment: You will leverage AI tools daily to write and optimise code, speed up root cause analysis, and generate documentation, raising the bar for engineering efficiency.
Grow and collaborate: You will actively work with senior engineers to elevate your own technical and architectural skills, while also supporting junior team members. You’ll help the team adopt best practices to keep development cycles efficient, secure, and reliable.
Expect challenges, collaboration, and the freedom to bring your ideas to life. Our tech stack includes (but is not limited to) PostgreSQL, Java, and Spring Boot. We rely on AWS for our infrastructure, with microservices deployed on EC2/ECS, S3 for storage, AWS Lambda for serverless functions, and Kinesis and ElasticSearch for log streaming. You'll take ownership of your assigned features and components from start to finish.
Who we’re looking for
We are looking for a proactive problem-solver who takes initiative and excels in building robust, mission-critical logic. Does it sound like you?
Experience: You have at least 3 years of experience as a Backend Engineer, with a proven track record of building and maintaining scalable microservices in fast-paced contexts.
Technical Foundations: Deep expertise in Java and Spring Boot. You have a solid understanding of distributed systems and experience (or strong interest) in managing external dependencies like banking APIs.
Cloud Awareness: Good exposure to cloud environments (AWS is a plus) and relational databases (PostgreSQL).
Reliability Mindset: You care deeply about system health, data integrity, and clean business logic. You are comfortable debugging complex issues across different services.
Communication: You are able to communicate technical concepts clearly and collaborate effectively with both technical and non-technical peers.
Passion and Language Skills: You are 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.
