Rate limiting, authentication (OAuth 2.0 + broker SSO), caching, versioning, and documentation.\nBroking Platform Core: Native order management system with full execution stack. Order placement, position sync, holdings management, margin calculation, and risk controls. Built as a unified platform layer, not a third-party broker abstraction.\nDecompose the monolith into domain-bounded microservices: User Service, Query Engine, Market Data Service, Portfolio Service, and Alert Service.\nReal-Time Infrastructure: WebSocket gateway for live data streaming to clients. Manage 10K+ concurrent connections, handle reconnection logic, and implement efficient subscription management.\nDevOps and Reliability: AWS EKS (Kubernetes) orchestration, CI/CD pipelines (GitHub Actions), auto-scaling policies, and incident response.\n\nRequirements: \n3-5 years in backend engineering with expertise in GoLang, C++, Rust, or Java.\nDistributed systems experience: microservices, event-driven architecture, message queues, eventual consistency.\nDatabase design: PostgreSQL (primary), Redis (caching + pub/sub), and time-series workloads.\nKubernetes + Docker in production. You've managed EKS/GKE clusters, written Helm charts, and configured auto-scaling policies.\nAPI design philosophy. You care about consistent response formats, proper HTTP semantics, pagination patterns, and error handling.\n\nBonus Points: \nExperience with broker/trading platform APIs; order lifecycle, market data WebSockets, and position management.\nWebSocket expertise at scale (10K+ concurrent connections, efficient pub/sub routing).\nYou've built fintech systems handling real money: payments, wallets, or trading platforms.\nSkills\nGo, Golang, Java, Trading, backend, distributed systems, event-driven, message queues, microservices","description_format":"text","description_chars":1946,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Machine Learning","Online Brokerage & Trading Platforms"],"lifecycle":[{"event":"open","at":"2026-10-26T13:37:00Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":4,"expected_fill_days":28,"reasons":["seen:4","velocity","win:early"],"computed_at":"2026-10-31T05:58:55Z"},"pay":null,"html_url":"https://alion.io/job/tradl-ai-senior-backend-engineer","json_url":"https://alion.io/job/tradl-ai-senior-backend-engineer.json","meta":{"generated_at":"2026-10-31T23:10:40Z","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":36163,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-01T00:00:00Z"}},"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":1981},"rest":"https://alion.io/mcp/rest/get_company?id=1981"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ftradl-ai-senior-backend-engineer"},{"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%2Ftradl-ai-senior-backend-engineer"},{"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%2Ftradl-ai-senior-backend-engineer"},{"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/tradl-ai-senior-backend-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ftradl-ai-senior-backend-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3274769}},{"tool":"search_jobs","arguments":{"company":"tradl.in","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3274769},"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.
