Our values prioritize putting the human in the center, and creating tools that we want to use ourselves, and recommend to our friends and family.\nAs a team, we work with high technical intensity and personal responsibility. We are looking for curious, self-motivated, creative, and technically excellent teammates to join us and build the future of human-AI interactions in software.\nThe Role\nWe are looking for an Agent Harness Software Engineer to build the core agent system behind Bionic, LM Studio’s agent for work and code. You will make open models effective at working with codebases, documents, files, software tools, and the user’s computer.\nOpen models vary widely in how they reason, call tools, use context, and recover from mistakes. You will build the software that handles those differences and gets the best possible agentic performance from models running locally, on linked devices, and in LM Studio's inference cloud.\nQualifications\nSignificant experience building production software involving language models, developer tools, or automation\n\nStrong understanding of tool calling, structured model output, context construction, and streaming inference\n\nExperience building stateful systems that perform multi-step work and recover cleanly from failures\n\nExcellent TypeScript and general software engineering fundamentals\n\nDeep interest in open models and a practical understanding of their strengths and limitations\n\nWorks with high technical intensity and takes personal responsibility for the finished product\n\nResponsibilities\nBuild and improve the agent harness that powers Bionic\n\nMake local and cloud models reliable at using files, search, Git, the shell, web tools, and document tools\n\nIntegrate new open models and optimize how they perform in the Bionic agent harness\n\nManage conversation history, working context, tool results, interruptions, and recovery\n\nBuild repeatable evaluations and diagnostics for understanding where and why an agent fails\n\nConstrain the model in a smart way so it remains useful\n\nWork across Bionic, the LM Studio runtime, and LM Studio cloud to improve the complete system\n\nBenefits\nCompetitive salary and equity grants\n\nGreat medical, vision, dental healthcare plans\n\nCatered team lunch / expensed dinners in the office\n\nFlexible PTO\n\nFlexible WFH\n\nSun-drenched office in SoHo in NYC","description_format":"text","description_chars":2476,"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":["Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["LLM & Generative AI","AI Development Tools"],"lifecycle":[{"event":"open","at":"2026-09-12T18:14:18Z"}],"visa":[],"liveness":{"score":13,"band":"cold","label":"Long shot","p_open":1,"p_active":0.302,"p_room":0.44,"age_days":70,"expected_fill_days":61,"reasons":["conf:3","win:tail","crowd:"],"computed_at":"2026-10-17T05:46:00Z"},"pay":{"stated_usd_annual":350000,"is_top_pay":true},"html_url":"https://alion.io/job/lm-studio-blog-software-engineer-agent-harness","json_url":"https://alion.io/job/lm-studio-blog-software-engineer-agent-harness.json","meta":{"generated_at":"2026-10-18T09:15:52Z","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":13787,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-19T00:00:00Z"}},"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":35399},"rest":"https://alion.io/mcp/rest/get_company?id=35399"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Flm-studio-blog-software-engineer-agent-harness"},{"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%2Flm-studio-blog-software-engineer-agent-harness"},{"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%2Flm-studio-blog-software-engineer-agent-harness"},{"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/lm-studio-blog-software-engineer-agent-harness\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Flm-studio-blog-software-engineer-agent-harness"}]}
