Poolday is creating a new category of creative tooling that combines a traditional timeline-based editor with autonomous AI agents that can understand intent, generate visuals, and manipulate projects end-to-end.\nThis role will work closely with the founders and early engineering team to design and implement the agentic architecture that powers the product. This is a high-ownership position with significant influence over system design, product direction, and engineering culture.\nAbout PooldayPoolday is building a modern video editor where users describe what they want, and intelligent agents assemble compositions, generate pixels, and perform edits autonomously. The product blends familiar creative workflows with cutting-edge agentic AI systems.\nThe founding team consists of experienced operators and builders with a strong track record of shipping complex products. Poolday is early-stage, product-driven, and focused on building category-defining creative tools.\n\nWhat You’ll Be Doing\n\nDesigning and building multi-agent systems in TypeScript, including a primary orchestration agent and specialized sub-agents\n\nArchitecting agent workflows that interpret user intent, plan multi-step edits, and execute them across a video timeline\n\nBuilding the interface layer between agents and the video editor, enabling agents to read project state, issue commands, and observe results in real time\n\nDeveloping agent capabilities for scene composition, visual generation, timing adjustments, effects, and compositing\n\nImplementing plan-and-execute loops, recovery strategies, and feedback mechanisms for reliable autonomous editing\n\nCreating memory and context systems that allow agents to reason about project state, user preferences, and editing history\n\nWorking closely with founders to shape both the product vision and the technical foundations of the platform\n\nWhat Poolday Is Looking ForMust-Have\n\n5+ years of professional software engineering experience with strong system design skills\n\nDeep expertise in TypeScript, including building large, maintainable codebases\n\nExperience building complex front-end or editor-like applications using React\n\nHands-on experience with agentic systems (e.g. LangChain.js, LangGraph.js, Vercel AI SDK, or custom agent frameworks)\n\nStrong understanding of agent orchestration patterns such as hierarchical delegation, multi-agent collaboration, and plan-and-execute loops\n\nExperience designing APIs or command layers to programmatically control complex applications\n\nStrong prompt engineering skills, including function calling and structured outputs\n\nAbility to work independently in ambiguous, fast-moving environments\n\nNice to Have\n\nExperience with video editing software, motion graphics, or creative tooling\n\nFamiliarity with generative Al for images or video\n\nExperience building plugin systems or extensible application architectures\n\nWhy Join PooldayThis is a chance to help define how AI agents will power creative tools. You’ll work on a product where users describe an idea and watch agents build it - composing scenes, generating visuals, and assembling edits autonomously.\nPoolday offers real ownership, deep technical challenges, and the opportunity to shape a product from early traction to scale.\nOriginally posted on Himalayas","description_format":"text","description_chars":3471,"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":[]},"benefits":[],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-11T20:32:15Z"}],"visa":[],"liveness":{"score":78,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.776,"p_room":1,"age_days":9,"expected_fill_days":30,"reasons":["seen:9","win:early"],"computed_at":"2026-10-21T05:46:15Z"},"pay":null,"html_url":"https://alion.io/job/a-players-senior-agentic-software-engineer-poolday","json_url":"https://alion.io/job/a-players-senior-agentic-software-engineer-poolday.json","meta":{"generated_at":"2026-10-21T21:03:07Z","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":29925,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-22T00:00:00Z"}},"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":3864752},"rest":"https://alion.io/mcp/rest/get_company?id=3864752"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fa-players-senior-agentic-software-engineer-poolday"},{"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%2Fa-players-senior-agentic-software-engineer-poolday"},{"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%2Fa-players-senior-agentic-software-engineer-poolday"},{"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/a-players-senior-agentic-software-engineer-poolday\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fa-players-senior-agentic-software-engineer-poolday"}]}
