Chiri must be one of their top answers.\nRole Overview\nWe're looking for a highly capable Backend Engineer to build fast, reliable, production-grade services for a transaction-intensive healthcare and pharmacy-finance platform.\nThis role requires a strong engineering foundation in concurrency, parallel programming, memory management, code profiling, and performance optimization.\nYou'll help build the services supporting real-time claim validation, decision engines, data processing, and enterprise integrations.\nKey Responsibilities\nPerformance Engineering: Develop backend services designed for demanding latency and throughput requirements.\nConcurrency & Parallelism: Build efficient concurrent systems with careful attention to threading, asynchronous execution, synchronization, and memory utilization.\nProfiling & Optimization: Identify and eliminate performance bottlenecks through code profiling, benchmarking, load testing, and runtime analysis.\nCold-Start Performance: Design and optimize initialization, warm-up, and cold-start mechanisms to minimize processing delays.\nDecision Systems: Implement reliable APIs, validation workflows, and rules-based processing with predictable and testable behavior.\nProduction Reliability: Ensure correctness, error handling, observability, security, and operational stability.\nRequired Skills and Experience\nStrong production backend engineering experience, preferably with Golang.\nDemonstrated expertise in concurrent and parallel programming, including race conditions, synchronization, and resource contention.\nDeep understanding of memory management, application runtime behavior, and performance profiling.\nProven ability to optimize latency and throughput in production systems.\nStrong fundamentals in statistics, including distributions, percentiles, variability, and performance measurement.\nExperience with APIs, databases, asynchronous processing, and distributed systems.\nExperience with Docker, Git, automated testing, and CI/CD.\nStrong debugging, problem-solving, and communication skills.\nPreferred Qualifications\nExperience in competitive programming.\nExperience building payment, transaction-processing, financial, or healthcare systems.\nExperience optimizing serverless execution and cold-start behavior.\nExperience with deterministic rules engines, real-time decision systems, or high-volume event processing.\nWhat We Offer\nThe opportunity to solve challenging performance problems and build the core transaction-processing capabilities of a new production platform.\nOur SCOUT Values\nOur values are not wall art. They describe how we expect people to operate.\nSeek to Understand\nAssume you might be wrong. Clarity before action.\nCall It Out\nSee something, say something. Say the hard thing.\nOwnership Mentality\n\"That's not my job\" does not exist.\nUse Human Judgment\nJudgment, context, and care come from us. AI is a tool.\nTalk with Precision\nConcise. Intentional.","description_format":"text","description_chars":3417,"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":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Managed IT Services (MSP)","AI Consulting & Integration"],"lifecycle":[{"event":"open","at":"2026-11-07T00:28:13Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":7,"expected_fill_days":28,"reasons":["conf:1","velocity","win:early"],"computed_at":"2026-11-14T05:58:10Z"},"pay":null,"html_url":"https://alion.io/job/chiri-backend-engineer-low-latency-systems","json_url":"https://alion.io/job/chiri-backend-engineer-low-latency-systems.json","meta":{"generated_at":"2026-11-14T20:33:59Z","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":25913,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-15T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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":4423461},"rest":"https://alion.io/mcp/rest/get_company?id=4423461"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fchiri-backend-engineer-low-latency-systems"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"free","price":{"credits":0,"usd":0},"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%2Fchiri-backend-engineer-low-latency-systems"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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%2Fchiri-backend-engineer-low-latency-systems"},{"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/chiri-backend-engineer-low-latency-systems\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fchiri-backend-engineer-low-latency-systems"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3900144}},{"tool":"search_jobs","arguments":{"company":"chiri.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3900144},"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.
