You will leverage your deep technical expertise to write prompts, produce reference-quality code solutions, evaluate model outputs, and provide the structured human signal that makes AI systems smarter.\nThis is not a traditional engineering role - it is a unique opportunity for senior engineers who want to shape how the next generation of AI understands, generates, and reasons about code.\nKey Responsibilities\nCreate and review coding tasks based on real-world software engineering scenarios, including debugging, refactoring, code generation, API usage, automated tests, performance, security, and edge cases.\nWrite high-quality reference solutions that are correct, clear, testable, and aligned with task requirements.\nEvaluate AI-generated code and responses using structured rubrics, assessing correctness, clarity, security, performance, maintainability, and instruction-following.\nCompare multiple model responses, select the strongest answer, and justify your decision with clear technical reasoning.\nIdentify bugs, hallucinated APIs, missing edge cases, weak explanations, and poor engineering decisions in AI-generated outputs.\nWork with terminal-based development workflows when needed, including running tests, debugging issues, managing dependencies, and navigating repositories.\nFollow detailed guidelines consistently and participate in calibration activities to ensure high-quality, reliable evaluations.\nCore Requirements\n5+ years of professional software engineering experience in a backend, fullstack, or systems role.\nStrong proficiency in at least one core programming language, ideally Python, JavaScript/TypeScript, Go, Java, C++, or SQL.\nHands-on experience with Terminal-Bench, with the ability to evaluate AI agent performance on terminal-based tasks including compiling code, running tests, managing environments, and completing multi-step software engineering workflows.\nComfortable working withGit, command line/terminal, and common development workflows.\nAbility toevaluate code critically - not only whether it works, but whether it is well-designed, secure, and maintainable.\nPrior experience in AI data production, RLHF, data annotation, or LLM evaluation projects.\nExcellent written and verbal communication skills in English.\nAbility to work independently in a remote, asynchronous, fast-paced environment.\nHigh attention to detail and the ability to follow complex, rubric-based guidelines consistently\nNice-to-Have\nExperience with Python-heavy workflows, automated testing frameworks, Docker, Linux, bash, or containerized environments.\nExperience with repo-level code reasoning, large codebases, or open-source contributions.\nBackground in backend systems, data engineering, DevOps, infrastructure, security, or large codebase.\nAdditional\n- US Timezone Overlap: PST (GMT -8)\nPlease Note: Due to the high volume of applications, only shortlisted candidates will be contacted.","description_format":"text","description_chars":3269,"description_truncated":false,"requirements":{"experience_years_min":5,"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":[],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"},{"name":"Canada","iso":"CA","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-28T11:40:14Z"}],"visa":[],"liveness":{"score":6,"band":"cold","label":"Long shot","p_open":1,"p_active":0.227,"p_room":0.28,"age_days":156,"expected_fill_days":22,"reasons":["conf:1","stale_co","velocity","win:tail","crowd:"],"computed_at":"2026-10-30T05:48:23Z"},"pay":null,"html_url":"https://alion.io/job/kake-senior-software-engineer-llm-trainer","json_url":"https://alion.io/job/kake-senior-software-engineer-llm-trainer.json","meta":{"generated_at":"2026-10-31T01:54:11Z","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":2623,"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":4454565},"rest":"https://alion.io/mcp/rest/get_company?id=4454565"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fkake-senior-software-engineer-llm-trainer"},{"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%2Fkake-senior-software-engineer-llm-trainer"},{"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%2Fkake-senior-software-engineer-llm-trainer"},{"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/kake-senior-software-engineer-llm-trainer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fkake-senior-software-engineer-llm-trainer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3394079}},{"tool":"search_jobs","arguments":{"company":"kake.co","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3394079},"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.
