The core challenge isn't just shipping code; it's managing high-performance compute workloads across 30+ event-driven microservices that must auto-scale under extreme live-event traffic spikes without failing.\nAbout the Product\nThe platform transforms live sports broadcasts into personalized, publication-ready highlight packages while games are actively in progress. Operating at continuous scale, it automatically ingests, analyzes, and tags video streams to identify key moments. The system processes massive data volumes with zero tolerance for latency, directly powering downstream consumer-facing media products.\nTechnology Stack: The backend core is built on C# and .NET, running distributed microservices orchestrated via Kubernetes in cloud environments like Azure. Asynchronous data flows and event-driven architecture rely on pub/sub messaging infrastructure (Kafka and Azure Service Bus) with relational SQL databases for persistent storage. The engineering team actively leverages modern AI tooling, including Claude Code, Cursor, custom skills, and sub-agents, directly within their delivery workflows.\nWhat You’ll Be Doing\nArchitect and operate low-latency, event-driven microservices that handle live event traffic bursts with zero downtime\n\nBridge ML models into production by building resilient deployment pipelines that handle model drift, context limits, and non-deterministic outputs\n\nOwn end-to-end service delivery from initial RFC design through zero-downtime deployment and post-launch telemetry\n\nOptimize pub/sub event pipelines across Kafka and Azure Service Bus to decrease processing latency and boost data throughput\n\nDebug distributed performance bottlenecks and scale Kubernetes compute clusters handling concurrent 24/7 media processing\n\nCollaborate with ML Engineers and Data Scientists to design systems that degrade gracefully during inference failures\n\nWhat We Expect\nMust-have\n4+ years scaling distributed microservices and backend systems in production cloud environments\n\nStrong expertise in C# / .NET for high-throughput, low-latency application development\n\nProduction experience with Kubernetes, relational schema design, SQL query performance tuning, and messaging infrastructure (Kafka, Azure Service Bus)\n\nHands-on integration of AI-assisted engineering tools (Cursor, Claude Code, sub-agents) into daily workflow\n\nNice-to-have\nOperational knowledge of production ML/AI behavior (inference performance, context limits, non-determinism)\n\nAzure cloud infrastructure experience (networking, IAM, cost/performance optimizations) or exposure to video/media processing pipelines\n\nWhy This Role Is Worth Your Time\nDirect ownership of high-concurrency event pipelines where code changes instantly impact live, broadcast-level media products\n\nPragmatic adoption of AI engineering practices - AI coding assistants and sub-agents are integrated into production workflows rather than treated as an afterthought\n\nExposure to complex distributed systems engineering, balancing massive scale, live media ingestion, and operational cost efficiency","description_format":"text","description_chars":3262,"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":"Poland","iso":"PL","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-09-12T07:59:26Z"}],"visa":[],"liveness":{"score":18,"band":"cold","label":"Long shot","p_open":1,"p_active":0.324,"p_room":0.55,"age_days":41,"expected_fill_days":33,"reasons":["conf:0","agency","velocity","win:tail"],"computed_at":"2026-10-15T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/newxel-net-backend-developer-nxj-195","json_url":"https://alion.io/job/newxel-net-backend-developer-nxj-195.json","meta":{"generated_at":"2026-10-15T12:23:06Z","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":19061,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-16T00:00:00Z"}},"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":679539},"rest":"https://alion.io/mcp/rest/get_company?id=679539"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fnewxel-net-backend-developer-nxj-195"},{"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%2Fnewxel-net-backend-developer-nxj-195"},{"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%2Fnewxel-net-backend-developer-nxj-195"},{"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/newxel-net-backend-developer-nxj-195\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fnewxel-net-backend-developer-nxj-195"}]}
