With over 25 years of experience and a team of 5,000 professionals across 16 countries, we help organizations design and build scalable products, platforms, and data-driven solutions.\n\nWe specialize in Artificial Intelligence, Data and Cloud, Intelligent Automation, and Digital Products, combining deep technical expertise with a strong focus on engineering excellence and a people-first culture.\n\nIn the CEE region, we’re a team of nearly 1,000 experts delivering modern applications, data platforms, and AI solutions for clients such as Millennium, ING, Play, Edenred, Arabian Drilling, FedEx, Leroy Merlin, Truecaller, Volotea, Schmitz Cargobull, and many, many more. We work with leading technologies including AWS, Azure, GCP, Databricks, and Snowflake, and combine strong engineering culture with a consulting mindset and a continuous focus on growth and knowledge sharing.\n\nThe project focuses on migrating and modernizing a business-critical enterprise platform for an international company in the rail transportation and asset-leasing sector.\n\nThe first phase establishes the technical foundation and migrates an initial set of business modules. The priority is to preserve existing functionality and business rules while introducing selected improvements in usability, automation, performance, observability, and security. Delivery follows a phased approach to support operational continuity throughout the transition.\n\nYou will be:\n\nBuilding a reusable application platform with shared components and common development patterns.\n\nMigrating existing business functionality while maintaining functional parity.\n\nUnderstanding and documenting complex business rules, data, and dependencies.\n\nIntegrating the new solution with enterprise systems and supporting data migration.\n\nDelivering incremental releases supported by automated testing, user acceptance testing, and post-release stabilization.\n\nThe technology stack includes C# and .NET for backend development, React and TypeScript for the frontend, and PostgreSQL for data storage. Cloud infrastructure uses AWS and Terraform, with xUnit, Vitest, and Playwright supporting automated testing.\n\nThe team works in an international delivery environment using Scrum, two-week sprints, and regular refinement, planning, and review sessions. Close collaboration between engineers, business stakeholders, and domain experts is essential to understanding existing processes and translating them into reliable software.\n\nFor candidates, the project offers an opportunity to combine modern application development with the challenges of enterprise migration. The work is particularly relevant to professionals who enjoy understanding complex systems, building reusable solutions, and delivering improvements within clearly defined business and technical constraints.\n\nTech stack:\n\n.NET ASP.NET Core WebAPI REST TDD Docker Azure DevOps GenAI exposure (Claude Code, GitHub Copilot) AWS as nice to have.\n\nThe technology stack includes C# and .NET for backend development, React and TypeScript for the frontend, and PostgreSQL for data storage.\n\nCloud infrastructure uses AWS and Terraform, with xUnit, Vitest, and Playwright supporting automated testing.\n\nYour profile:\n\nPractical experience using AI-powered assistants (e.g. Claude Code, GitHub Copilot, Cursor) to improve productivity, quality, or decision-making in software delivery.\n\nWork from the European Union region and a work permit are required.\n\nNice to have:\n\nExperience applying GenAI in a more structured way within the SDLC, including defined workflows, prompt patterns, or tool integrations embedded into daily work.\n\nInterest in and familiarity with emerging AI-driven practices (e.g. agent-based workflows, automation patterns, AI-augmented development), with a willingness to explore and experiment beyond standard approaches.","description_format":"text","description_chars":3925,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"Bulgaria","iso":"BG","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Corporate Training","IT Consulting & Digital Transformation","AI Consulting & Integration","IT Training & Certification"],"lifecycle":[{"event":"open","at":"2026-11-04T17:22:00Z"}],"visa":[],"liveness":{"score":63,"band":"ok","label":"Likely open","p_open":1,"p_active":0.632,"p_room":1,"age_days":2,"expected_fill_days":56,"reasons":["seen:2","stale_co","velocity","win:early"],"computed_at":"2026-11-07T05:47:08Z"},"pay":null,"html_url":"https://alion.io/job/xebia-senior-net-developer","json_url":"https://alion.io/job/xebia-senior-net-developer.json","meta":{"generated_at":"2026-11-07T07:50:00Z","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":3504,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-08T00:00:00Z"}},"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":1386},"rest":"https://alion.io/mcp/rest/get_company?id=1386"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fxebia-senior-net-developer"},{"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%2Fxebia-senior-net-developer"},{"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%2Fxebia-senior-net-developer"},{"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/xebia-senior-net-developer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fxebia-senior-net-developer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3757636}},{"tool":"search_jobs","arguments":{"company":"xebia.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3757636},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
