You’ll use AI to build OpenRewrite recipes that modernize outdated Java applications automatically and close known security vulnerabilities. That keeps software running that society relies on every day, and protects it from attacks.\nTired of touching hundreds of files by hand every time you upgrade? A new Java version, a framework switch, a library with a known vulnerability, and in the end you still miss one spot. Then the next application comes along and it all starts over.\nWhy it matters\nA large share of the software that public agencies, companies and people rely on every day runs on Java. Much of it has grown over many years and is stuck on versions and libraries that stopped getting security updates long ago. Every outdated dependency is an open door for attackers. In 2021, Log4Shell showed how quickly a single library can become a global problem. At the same time, there are far too few developers to bring all that code up to date by hand.\nThat’s where we come in. OpenRewrite applies code changes as recipes: automated, traceable and repeatable across entire codebases. Writing those recipes used to take a lot of effort. Claude Code is changing that right now. The agent writes the first draft including tests, you review it, refine it and run the recipe against real customer code. A good recipe doesn’t just close a gap in one project. It closes it in every codebase it’s applied to.\nThis is how we modernize our customers’ Java applications at XDEV and keep them secure and maintainable for years to come. We’re looking for someone who wants to help shape this still-young field with us.\nWhat you’ll do\nAnalyze our customers’ long-lived codebases and figure out what’s outdated and where the security risks are\nModernize across the board: new Java versions, the move from javax to jakarta, framework and library upgrades, and replacing dependencies with known vulnerabilities\nHave Claude Code write OpenRewrite recipes and matching tests, review the output critically and refine it until it’s right\nCombine recipes from the OpenRewrite catalog with your own where the catalog falls short\nRun recipes against real customer code and make sure the result is a clean, reviewable pull request\nSound interesting?\nOpenRewrite, Claude Code, Java 8 through 25, Jakarta EE, Spring, Hibernate, JUnit, Lossless Semantic Trees, Refaster templates, CVEs, Git, legacy code, coffee\nIf you thought “yes” to most of these, this is the right job for you.\nWhat we offer?\nMeaningful work: you make software more secure that many people depend on, and you see the impact of your recipes\nAgile work with a startup feel, backed by the stability of an established company\nHelp shape a young field from the start and have a say in how we use AI for modernization\nWork with Claude Code and current models. We provide access.\nFlexible working hours\nExclusive training, certifications and conference visits, so you learn early what’s coming and how to work with it\nLong-term prospects\nFlat hierarchies and transparent communication\nLearn more about how we work at XDEV here\nYour profile\nAt least 2 years of professional experience in Java development\nYou already work with Claude Code and know how to give the agent the right context, review its output critically and steer it in the right direction\nExperience with upgrades and migrations in long-lived Java applications, whether Java versions, frameworks or libraries\nSecurity isn’t a side topic for you. Outdated dependencies and open CVEs bother you.\nYou enjoy writing not just code, but code that changes code\nTesting isn’t a chore: a recipe is only done when the tests show it does what it should\nSome experience with OpenRewrite is a plus. You’ll learn the rest with us.\nYou’re a team player and work reliably, independently and with commitment\nLocation\nWeiden in der Oberpfalz, Germany / Remote / No staff augmentation\nStart date\nImmediately, full-time\n\n/fileadmin/_processed_/9/1/csm_Richard_Fichtner_c92d82f5e1.webp 768w,\n/fileadmin/_processed_/9/1/csm_Richard_Fichtner_caede46a8f.webp 1200w,\n/fileadmin/_processed_/9/1/csm_Richard_Fichtner_81f78dd63f.webp 1920w,\n/fileadmin/_processed_/9/1/csm_Richard_Fichtner_81f78dd63f.webp 2560w\"\nsizes=\"(-webkit-min-device-pixel-ratio: 2.1) 300vw, (-webkit-min-device-pixel-ratio: 1.1) 200vw, 100vw\"\ntype=\"image/webp\">\n/fileadmin/_processed_/9/1/csm_Richard_Fichtner_200e590015.jpg 768w,\n/fileadmin/_processed_/9/1/csm_Richard_Fichtner_4072b0e1bc.jpg 1200w,\n/fileadmin/_processed_/9/1/csm_Richard_Fichtner_02a8ba1680.jpg 1920w,\n/fileadmin/_processed_/9/1/csm_Richard_Fichtner_02a8ba1680.jpg 2560w\"\nsizes=\"(-webkit-min-device-pixel-ratio: 2.1) 300vw, (-webkit-min-device-pixel-ratio: 1.1) 200vw, 100vw\">\nYour contact person:\nRichard Fichtner\nPlease send us your complete application exclusively as a PDF via e-mail including\nCV\nPossible start date\nCompensation expectations\nor simply send your questions to:\n\nRight from the first day, we make every effort with our onboarding program to ensure that possible hurdles are removed and that you have a good start at XDEV by all accounts.\nOnboarding at XDEV","description_format":"text","description_chars":5195,"description_truncated":false,"requirements":{"experience_years_min":2,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Flexible schedule"],"hiring_locations":[{"name":"Germany","iso":"DE","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-22T15:20:34Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":1,"expected_fill_days":20,"reasons":["conf:34","win:early","comp:junior"],"computed_at":"2026-10-24T06:02:35Z"},"pay":null,"html_url":"https://alion.io/job/xdev-software-gmbh-software-modernisierer-wmd-java-openrewrite-ki-bei-xdev","json_url":"https://alion.io/job/xdev-software-gmbh-software-modernisierer-wmd-java-openrewrite-ki-bei-xdev.json","meta":{"generated_at":"2026-10-24T12:10:46Z","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":17511,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-25T00:00:00Z"}},"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":1843939},"rest":"https://alion.io/mcp/rest/get_company?id=1843939"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fxdev-software-gmbh-software-modernisierer-wmd-java-openrewrite-ki-bei-xdev"},{"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%2Fxdev-software-gmbh-software-modernisierer-wmd-java-openrewrite-ki-bei-xdev"},{"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%2Fxdev-software-gmbh-software-modernisierer-wmd-java-openrewrite-ki-bei-xdev"},{"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/xdev-software-gmbh-software-modernisierer-wmd-java-openrewrite-ki-bei-xdev\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fxdev-software-gmbh-software-modernisierer-wmd-java-openrewrite-ki-bei-xdev"}]}
