In this role, you'll apply your expertise to help train next-generation AI systems. Your work will shape how models learn, reason, and perform through high-quality, real-world input. No prior experience in AI is required — your domain knowledge is what matters.\nAs an expert, you will create Reinforcement Learning Environments that test an AI model’s ability to design, deploy, troubleshoot, secure, scale, and recover production-grade cloud infrastructure. You will develop realistic scenarios involving distributed systems, networking, IAM, queues, durable storage, observability, rolling deployments, and disaster recovery, then build reproducible environments, deterministic validation tests, golden reference solutions, and intentionally defective variants.\nRequired Skills\nC++\n\nPython\n\nRust\n\nGoLang\n\nJAVA\n\nJavaScript\n\nDevOps\n\nScope of Work\nDesign, develop, and implement realistic cloud infrastructure environments to evaluate AI model proficiency in systems design, deployment, and troubleshooting.\n\nCreate detailed and reproducible scenarios involving distributed systems, networking, Identity and Access Management (IAM), message queues, persistent storage, observability, rolling deployments, and disaster recovery.\n\nDevelop deterministic validation tests and golden reference solutions to ensure the reliability and accuracy of reinforcement learning environments.\n\nProduce intentionally defective variants and failure scenarios to rigorously test AI model responses and recovery strategies.\n\nDocument the architecture, edge cases, and operational flows for all developed environments, ensuring clarity and reproducibility for future use.\n\nCollaborate with technical leads and project participants to iteratively refine environment specifications and acceptance criteria.\n\nApply DevOps and infrastructure automation practices to deliver scalable, secure, and maintainable solutions for cloud-based systems evaluation.\n\nPreferred Qualifications\nProven expertise with backend programming languages, such as C++, Python, Rust, GoLang, JAVA, or JavaScript.\n\nStrong practical experience with DevOps, cloud infrastructure, CI/CD pipelines, and automation tools.\n\nDemonstrated ability to architect, scale, and secure distributed systems in production-grade environments.\n\nDeep understanding of networking, IAM, queues, durable storage, and disaster recovery concepts.\n\nProcess:\nApply to the role, filling out the screening questions\n\nComplete AI interview (aprox. 30 minutes), reviewed by recruiters)\n\nHiring Manager review\n\nCompensation StructureCompensation is output-based; experts are paid per task that meets the project specifications. The time required to complete work may vary depending on the expert’s experience and workflow. Minimum submission requirements apply. Experts must submit a minimum of tasks per week.\nStart Timeline & AvailabilityWe typically fill roles within 48 hours and are looking for experts ready to jump in right away. If selected, we expect you to start your first tasks within 24–48 hours of completing onboarding.\nOriginally posted on Himalayas","description_format":"text","description_chars":3379,"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":[],"lifecycle":[{"event":"open","at":"2026-10-21T02:28:15Z"}],"visa":[],"liveness":{"score":69,"band":"ok","label":"Likely open","p_open":0.85,"p_active":0.903,"p_room":0.9,"age_days":17,"expected_fill_days":35,"reasons":["seen:17","velocity","win:mid"],"computed_at":"2026-10-24T06:02:35Z"},"pay":null,"html_url":"https://alion.io/job/xperteez-technology-senior-backend-engineer-remote-contract","json_url":"https://alion.io/job/xperteez-technology-senior-backend-engineer-remote-contract.json","meta":{"generated_at":"2026-10-24T22:15:28Z","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":32588,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-25T00:00:00Z"}},"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":4435561},"rest":"https://alion.io/mcp/rest/get_company?id=4435561"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fxperteez-technology-senior-backend-engineer-remote-contract"},{"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%2Fxperteez-technology-senior-backend-engineer-remote-contract"},{"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%2Fxperteez-technology-senior-backend-engineer-remote-contract"},{"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/xperteez-technology-senior-backend-engineer-remote-contract\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fxperteez-technology-senior-backend-engineer-remote-contract"}]}
