Job description

*Please note: we are only able to consider candidates who already have the right to work in Poland. Visa sponsorship is not available for this role.*

Every day, billions of transactions move through the global banking system.

Fraud hides in that data. So do compliance risks, operational failures, and patterns most systems never surface.

At Vyntra, we build the technology that makes those things visible — in real time.

Our platform is used by over 130 financial institutions globally to detect fraud, prevent money laundering, and understand transactions at scale. It combines advanced search technology with AI to process and analyse vast volumes of data as it happens.

The role

We’re hiring a Senior Software Developer to join our Financial Crime Product Development team.

You’ll work in a small, autonomous team building and evolving a large-scale, enterprise platform used by global banks. The work spans backend services and modern web applications — designing and delivering features that process and present complex transactional data in real time.

This is a hands-on role with real ownership. You’ll take features from problem through to production, working across the stack where needed. The team is small, so impact is visible — and expectations are high.

About you

You’ve built and run production systems and are comfortable working on complex problems without heavy structure.

You bring:

• Strong experience with Java and Spring Boot
• Experience contributing to modern web applications (Angular preferred)
• Experience working with distributed or cloud-based systems
• A structured approach to problem solving and a focus on root cause
• Experience working in agile teams with close collaboration
• Clear, practical communication

You’re primarily backend, but comfortable working across the stack when needed.

You’ll likely have worked with technologies such as Kafka, Docker, Kubernetes, SQL databases, and observability tools like Grafana. Experience with Elasticsearch, Spark, or similar is a plus.

Why Vyntra

The problems are real, the scale is significant, and the work matters.

You’ll be part of a team that values ownership, clarity, and good engineering judgement — working on systems that directly impact how financial institutions detect and prevent financial crime.
