Mid/Senior Java Backend Engineer - Insurance

About the Project

You'll join an international team (Scandinavia / Belgium / Poland) building and developing proprietary, scalable Enterprise-class platforms for the global insurance sector. Our systems manage the full policy lifecycle and claims settlement processes end to end, handling millions of operations per month - including financial settlement, accounting, investment fund, and claims modules (FIN/FUN/CLAIMS).

AI on our team is an everyday engineering tool, not a marketing buzzword - we work in a Spec Driven Development paradigm: we use AI agents for technical documentation, task specification, building technical plans, and verifying and testing work.

Who We're Looking For

We're looking for an experienced Java Backend Engineer (5+ years) with a strong backend foundation who is open to gradually learning and working with the frontend (Angular) - a deliberate choice by the client: a strong backend foundation plus a willingness to grow toward fullstack over time.

What You'll Do

• Design and develop backend services in Java (Spring Boot) for financial settlement, accounting, investment fund, and claims-handling modules
• Build and maintain high-performance REST APIs and integrations with external service providers
• Own architecture and code quality - Clean Code, design patterns, code review
• Collaborate with the team (BA, QA, Frontend, Scrum Master) in Agile/Scrum/SAFe methodologies
• Gradually get involved with the frontend (Angular/TypeScript) as project needs arise

What We're Looking For

• 5+ years of commercial experience with Java and Spring Boot
• Strong skills designing high-performance REST APIs
• Openness to learning and working with Angular (TypeScript)
• Practical knowledge of document databases (e.g. MongoDB) and relational databases (e.g. PostgreSQL, Oracle)
• Architectural thinking - SOLID, Clean Code
• English at B2 level or higher
• Polish at A1/A2 level
• Openness to AI-assisted programming in the Spec Driven Development model

Nice to Have

• Experience with Docker, ElasticSearch/Kibana
• Understanding of insurance product specifics, claims settlement processes, or market regulations
• Practical knowledge of DDD (Domain-Driven Design) or Event-Driven Architecture

Terms of Cooperation

• Locations: Kraków, Gdańsk, Łódź, Poznań
• Work model: initial onboarding period (up to 3 months) more often from the office, eventually hybrid - 3 days office / 2 days remote
• B2B: paid leave (20-26 days, agreed with the Hiring Manager)

What's In It For You

• Private medical care with Allianz - for you and your family
• Cafeteria benefits system (Multisport, culture, leisure, sports, shopping)
• Individual training and conference plan
• Participation in international projects for the financial and insurance sector
• Development path: expert (technical/business) or managerial

Recruitment Process

• Screening call (15-20 min)
• Test - a short (~20 min) AI Readiness test for candidates with 5+ years of experience, or a Codility test for less experienced candidates
• Meeting with the Hiring Manager (60 min)
