Tech giants & unicorns, transformative projects, emerging technologies and limitless opportunities - these are a few words that describe an average day for us. Building cross-functional engineering teams that take ownership and crave more means we’re always on the lookout for talented people who bring passion and creativity to every project. Our culture embraces openness, acts with respect, shows grit & guts and combines cooperation with enjoyment.\n Project - the aim you’ll have\nJoin a next-generation risk analysis and scoring platform built for a payments technology company. The platform combines the client’s own risk rules with AI-driven, pre-scored risk feeds from a global card network over high-volume payment data under PCI DSS. You’ll own the C#/.NET services and API contracts the analyst-facing apps run on, in a small AI-first delivery team alongside a frontend-leaning developer.\nRole - how you’ll contribute\nDesign, build and ship production C#/.NET services and REST APIs serving high-volume payment and risk data under PCI DSS constraints\nOwn API contracts with the front end: typed OpenAPI contracts, versioning and backward-compatible change\nWrite efficient data access against the operational database and Microsoft Fabric Gold-layer risk tables at analyst-scale volumes\nImplement security-critical concerns: authentication, authorization, audit logging and PCI-safe handling of tokenized card data\nContribute to the React and TypeScript front end - building features end to end, reviewing and pairing\nUse Claude Code or an equivalent agentic coding tool as your primary accelerator, backed by unit, integration and contract tests, while owning the quality of every line merged\nMaintain Dockerfiles and Compose configurations, support deployments to AKS and contribute to Azure DevOps CI/CD\nImplement against the target architecture set by the client’s architecture group, raise risks early and hand off work the internal team can own\n Expectations - the experience you need\n7+ years of commercial software development, including 5+ years of production-grade C#/.NET (ASP.NET Core, async, DI, EF Core or Dapper)\nStrong API design: REST conventions, OpenAPI contracts, versioning and evolving APIs without breaking consumers\nRelational database and distributed-systems skills: schema design, query tuning, transactional correctness, idempotency, failure handling\nWorking proficiency in React and TypeScript - able to build features end to end and review frontend code\nDaily, hands-on use of agentic AI coding tools (Claude Code, Cursor, Copilot Workspace, Codex or similar) and a track record of shipping AI-accelerated code that holds up in production - you’ll demo your workflow live\nContainers: Docker (multi-stage builds, hardening), Docker Compose and Kubernetes (AKS preferred)\nTesting discipline: xUnit or NUnit, integration testing with real dependencies (e.g. Testcontainers) and contract testing\nGit, CI/CD (Azure DevOps, GitHub Actions or similar) and autonomy in an existing codebase\nAdditional skills - the edge you have\nPayments, card processing, risk/fraud or merchant services experience, ideally with PCI-scoped systems\nMicrosoft Fabric, Delta Lake or building APIs over analytical data stores\nMessaging and observability: Azure Service Bus, Event Hubs or Kafka; OpenTelemetry and Application Insights\nIdentity standards: OAuth2/OIDC, Microsoft Entra ID, managed identity\nPython and exposure to LLM-integrated or agentic applications (e.g. LangGraph); prior consulting experience\n What we offer:\nFlexible and remote cooperation options\nInternational projects with leading global clients\nTravels related to international projects\nNon-corporate atmosphere\nAccess* to language classes\nAccess* to knowledge-sharing initiatives\nAccess* to private healthcare and life insurance\nAccess* to multisport card\n*The availability and terms of individual benefits may vary depending on the chosen form of cooperation.","description_format":"text","description_chars":4029,"description_truncated":false,"requirements":{"experience_years_min":7,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"English","level":"All levels","optional":false}]},"benefits":["Life insurance"],"hiring_locations":[{"name":"Poland","iso":"PL","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["IT Outsourcing & Dedicated Teams","Custom Software Development","Cloud Consulting & Migration"],"lifecycle":[{"event":"open","at":"2026-11-04T13:45:59Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":1,"expected_fill_days":15,"reasons":["conf:0","velocity","win:early"],"computed_at":"2026-11-06T05:58:05Z"},"pay":null,"html_url":"https://alion.io/job/software-mind-wap-senior-full-stack-developer-react-net","json_url":"https://alion.io/job/software-mind-wap-senior-full-stack-developer-react-net.json","meta":{"generated_at":"2026-11-06T23:45:55Z","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":3713,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-07T00:00:00Z"}},"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":7464},"rest":"https://alion.io/mcp/rest/get_company?id=7464"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fsoftware-mind-wap-senior-full-stack-developer-react-net"},{"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%2Fsoftware-mind-wap-senior-full-stack-developer-react-net"},{"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%2Fsoftware-mind-wap-senior-full-stack-developer-react-net"},{"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/software-mind-wap-senior-full-stack-developer-react-net\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fsoftware-mind-wap-senior-full-stack-developer-react-net"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3747210}},{"tool":"search_jobs","arguments":{"company":"softwaremind.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3747210},"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);
