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).\nAI 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.\nWho We're Looking For\nWe'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.\nWhat You'll Do\nDesign and develop backend services in Java (Spring Boot) for financial settlement, accounting, investment fund, and claims-handling modules\n\nBuild and maintain high-performance REST APIs and integrations with external service providers\n\nOwn architecture and code quality - Clean Code, design patterns, code review\n\nCollaborate with the team (BA, QA, Frontend, Scrum Master) in Agile/Scrum/SAFe methodologies\n\nGradually get involved with the frontend (Angular/TypeScript) as project needs arise\n\nWhat We're Looking For\n5+ years of commercial experience with Java and Spring Boot\n\nStrong skills designing high-performance REST APIs\n\nOpenness to learning and working with Angular (TypeScript)\n\nPractical knowledge of document databases (e.g. MongoDB) and relational databases (e.g. PostgreSQL, Oracle)\n\nArchitectural thinking - SOLID, Clean Code\n\nEnglish at B2 level or higher\n\nPolish at A1/A2 level\n\nOpenness to AI-assisted programming in the Spec Driven Development model\n\nNice to Have\nExperience with Docker, ElasticSearch/Kibana\n\nUnderstanding of insurance product specifics, claims settlement processes, or market regulations\n\nPractical knowledge of DDD (Domain-Driven Design) or Event-Driven Architecture\n\nTerms of Cooperation\nLocations: Kraków, Gdańsk, Łódź, Poznań\n\nWork model: initial onboarding period (up to 3 months) more often from the office, eventually hybrid - 3 days office / 2 days remote\n\nB2B: paid leave (20-26 days, agreed with the Hiring Manager), contract of employment available\n\nWhat's In It For You\nPrivate medical care with Allianz - for you and your family\n\nCafeteria benefits system (Multisport, culture, leisure, sports, shopping)\n\nIndividual training and conference plan\n\nParticipation in international projects for the financial and insurance sector\n\nDevelopment path: expert (technical/business) or managerial\n\nRecruitment Process\nScreening call (15-20 min)\n\nMeeting with the Hiring Manager (60 min)\n\nTech stack\nJava and Spring Boot","description_format":"text","description_chars":2961,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Cafeteria"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-08T22:59:03Z"}],"visa":[],"liveness":{"score":73,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.808,"p_room":0.9,"age_days":11,"expected_fill_days":26,"reasons":["seen:11","win:mid"],"computed_at":"2026-10-19T05:45:15Z"},"pay":null,"html_url":"https://alion.io/job/techtree-midsenior-java-backend-engineer-insurance","json_url":"https://alion.io/job/techtree-midsenior-java-backend-engineer-insurance.json","meta":{"generated_at":"2026-10-20T02:36:51Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":2955,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-21T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":3996479},"rest":"https://alion.io/mcp/rest/get_company?id=3996479"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ftechtree-midsenior-java-backend-engineer-insurance"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Ftechtree-midsenior-java-backend-engineer-insurance"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Ftechtree-midsenior-java-backend-engineer-insurance"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/techtree-midsenior-java-backend-engineer-insurance\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ftechtree-midsenior-java-backend-engineer-insurance"}]}
