With thousands of users and rapidly growing enterprise adoption, our mission is to democratize access to LLMs and bring AI into the hands of every business operator, not just developers. An Asana Company, we're building the foundational platform for the AI-driven future of work\nThe Role\nWe're looking for a senior frontend engineer who is incredible at execution. This is not about building flashy new features from scratch-it's about optimizing, refining, and incrementally improving what we've already built. You'll work closely with our Product Design pod to turn detailed visual specs into clean, production-ready code.\nMain Mission: Remove the bottleneck in our Product Design pod by taking ownership of incremental UX/UI improvements to existing features and code.\nWhat You'll Do\nOptimize and refine existing frontend code and features\n\nImplement incremental UX/UI improvements from detailed design specs (no design skills required)\n\nWork autonomously with minimal code review needed-your code should be clean enough that our other Front Enders can trust it blindfolded\n\nCollaborate with Product Designers, Design Engineers, and Front End Engineers on execution\n\nFocus on high-impact improvements that elevate our product quality and user experience\n\nClean up and improve legacy code\n\nWhat We're Looking For\nMust-haves:\nExceptional code quality: Clean, maintainable, trustworthy code that requires minimal review\n\nStrong execution: You ship fast and ship well\n\nSenior-level experience: 5+ years with React, TypeScript, Next.js, and modern frontend stack\n\nAccountability: You own your decisions and respond when needed\n\nAutonomy: You can own features end-to-end without hand-holding\n\nPragmatism: You are willing to engage with detail-oriented and iterative work that is essential to the product's success\n\nTechnical excellence: Someone who can teach us, not someone we have to teach\n\nNice-to-haves:\nExperience with Tailwind CSS\n\nUnderstanding of UI fundamentals (but design skills are NOT required)\n\nExperience cleaning up and optimizing existing codebases\n\nComfort working across the stack when needed\n\nOur Tech Stack\nReact, Next.js, TypeScript, Tailwind CSS, TanstackQuery\nWhat We Value\nHigh bar: We only hire people who wow us technically-someone better than us\n\nTrust: We've learned that even \"boring tasks\" require exceptional engineers, because poor execution takes more time to review than to do right the first time\n\nExecution over excitement: You're motivated by doing excellent work, not just working on the newest, shiniest features\n\nWhy This Role Matters\nThe Product Design pod has ambitious plans in the roadmap, and we need a frontend engineer who can execute flawlessly to keep pace. You'll be critical to ensuring our product quality and velocity.\nThis role description captures the team's emphasis on exceptional technical quality, execution, and pragmatism over design skills or working on only the most exciting features.","description_format":"text","description_chars":3098,"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":"Spain","iso":"ES","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["AI Agents","AI Development Tools","Low-Code & No-Code Platforms"],"lifecycle":[{"event":"open","at":"2026-01-24T19:59:11Z"}],"visa":[],"liveness":{"score":7,"band":"cold","label":"Long shot","p_open":1,"p_active":0.246,"p_room":0.28,"age_days":270,"expected_fill_days":39,"reasons":["conf:0","stale_co","ghost","win:tail","crowd:"],"computed_at":"2026-10-22T06:10:10Z"},"pay":{"stated_usd_annual":142559,"is_top_pay":false},"html_url":"https://alion.io/job/stackai-senior-frontend-engineer","json_url":"https://alion.io/job/stackai-senior-frontend-engineer.json","meta":{"generated_at":"2026-10-22T16:03:09Z","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":16154,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-23T00:00:00Z"}},"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":38249},"rest":"https://alion.io/mcp/rest/get_company?id=38249"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fstackai-senior-frontend-engineer"},{"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%2Fstackai-senior-frontend-engineer"},{"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%2Fstackai-senior-frontend-engineer"},{"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/stackai-senior-frontend-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fstackai-senior-frontend-engineer"}]}
