Today’s systems leak $1.7T in waste each year in retail alone - in overproduction, lost revenue, and unnecessary emissions.\nMercator’s founders are seasoned technical operators with a decade of experience leading cutting-edge AI and simulation efforts across Google (Gemini, Tensorflow, & Google X). We recently raised $5M in seed funding from leading Silicon Valley investors and are scaling our small, elite engineering team to meet growing customer demand.\nRole Description\nAs a member of our full-stack team, you’ll build the interface that brings our simulation platform to life and redefines what usability looks like in a category historically dominated by Excel. You’ll design and ship consumer-grade experiences that make complex operational decisions feel simple, intuitive, and fast. A major part of this role is driving mindset and behavior change through UX: helping users shift from static spreadsheets to interactive, scenario-driven systems.\nYou’ll work directly with customers to understand real workflows, translate them into modern product patterns, and own the full stack across Next.js and NestJS. A critical part of the job is listening carefully to what customers ask for, recognizing when requests point in the wrong direction, and extracting the underlying workflow problem they’re actually trying to solve.\nYou’ll collaborate closely with the engineer building our simulation engine to ensure advanced system output becomes clear, actionable, and trustworthy. You’ll be defining not just our product, but the way an entire industry interacts with operational data.\nBenefits\nComprehensive health, dental, and vision insurance\n\nAs a company we’ll work from a fun destination (think: skiing, surfing) two weeks a year\n\n---\nApplicants must have valid U.S. work authorization. We are able to support H-1B transfers but are not initiating new visa sponsorships at this time.","description_format":"text","description_chars":1983,"description_truncated":false,"requirements":{"experience_years_min":10,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Vision insurance"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["AI Agents","Management Consulting"],"lifecycle":[{"event":"open","at":"2026-09-02T07:28:31Z"},{"event":"open","at":"2026-09-26T05:40:14Z"}],"visa":[],"liveness":{"score":9,"band":"cold","label":"Long shot","p_open":1,"p_active":0.33,"p_room":0.28,"age_days":318,"expected_fill_days":31,"reasons":["conf:2","win:tail","crowd:"],"computed_at":"2026-10-31T05:58:55Z"},"pay":{"stated_usd_annual":200000,"is_top_pay":false},"html_url":"https://alion.io/job/mercator-full-stack-engineer","json_url":"https://alion.io/job/mercator-full-stack-engineer.json","meta":{"generated_at":"2026-10-31T23:49:52Z","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":37338,"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":456074},"rest":"https://alion.io/mcp/rest/get_company?id=456074"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fmercator-full-stack-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%2Fmercator-full-stack-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%2Fmercator-full-stack-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/mercator-full-stack-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fmercator-full-stack-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":188991}},{"tool":"search_jobs","arguments":{"company":"mercatorintelligence.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":188991},"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.
