Senior Backend Software Engineer - Consumer Growth

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 Senior Backend Software Engineer, you'll play a critical role in shaping the technical direction of the Consumer Growth team. This is an individual contributor (IC) role - you'll lead through technical excellence and influence, not through direct reports or people management. You will be responsible for the technical quality and delivery of complex systems, collaborating closely with other teams.

Here's what that looks like in practice:

• Build and ship - Design, implement, and operate services that power the Satispay consumer experience - from payment flows and identity verification to loyalty and engagement features, working across the full lifecycle.

• Cross-team technical leadership - Drive technical analysis for projects that cut across multiple teams, lead design discussions, and produce documentation that gives stakeholders and other teams a clear, reviewable picture of every design before build begins.

• Foster engineering excellence - Raise the quality bar across mobile and backend development through rigorous testing strategies, safe progressive rollouts, and proactive elimination of technical debt in a codebase shipping 2M+ daily payments.

• Mentor and develop - Provide technical guidance to junior and mid-level engineers in the Consumer Growth teams, helping them navigate cross-service dependencies, adopt sound event-driven patterns, and build operational excellence.

Expect challenges, collaboration, and the freedom to bring your ideas to life. Our tech stack includes (but it’s not limited to) PostgreSQL, Java, 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 work from start to finish.

Who we’re looking for

This role needs someone who is a proven problem-solver, takes initiative, excels in cross-team collaboration, and is a technical quality champion.

• Extensive experience - At least 5 years of related experience in back-end software engineering, with a proven track record in microservices and cloud environments (AWS is a plus) in high-paced contexts.

• Technical depth - Deep experience with Java and Spring Boot, alongside a strong understanding of distributed systems and managing external dependencies (like banking protocols).

• AI focus - Passionate about or hands-on experience building GenAI-driven features (e.g., backend services using LLMs, orchestration frameworks like LangGraph, or AWS cloud services like Amazon Bedrock).

• Structured communication - Ability to communicate complex technical concepts clearly, coordinate implementations across teams, and build trust with stakeholders.

• Impact mindset - Focused on delivering software that meets evolving user needs, adaptable, avoids analysis paralysis, and optimizes systems beyond initial requirements.

• Passion and language skills - 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.
