Include “Product engineering is cool” in the subject line. Otherwise, your application will be disqualified.\nYou will work across the application stack, use AI as a serious development tool, and make product decisions with real user and business data. The role rewards fast learning and strong engineering judgment, not raw code volume.\nAbout Single Grain\nSingle Grain is a revenue marketing agency. We build pipeline-focused systems that compound, not campaigns that expire. We have helped more than 500 companies, from venture-backed startups to the Fortune 500, drive measurable growth.\nWe operate as an AI-native team. Every role uses AI to improve speed, quality, judgment, and leverage. AI-generated code still requires sound architecture, testing, security, observability, and human review.\nYour missionBuild and improve products that create customer value and convert more users into retained, paying customers.\nPrimary KPI: increase trial-to-paid conversion from the current baseline toward 40%, while maintaining product quality and learning velocity. By month six, the target operating cadence is at least two meaningful product experiments per month.\nWhat you will own\nTurn user problems and product hypotheses into scoped experiments.\n\nBuild production features across the front end, back end, data layer, and integrations.\n\nDefine instrumentation before launch and read the result after launch.\n\nImprove activation, conversion, retention, reliability, and developer speed.\n\nUse AI for exploration, implementation, tests, debugging, and documentation with explicit QA.\n\nMake practical architecture and security tradeoffs, then document them.\n\nSpeak with users and partner with growth, design, and operations when the product needs context.\n\nWhat success looks likeIn 30 days, you understand the product, users, stack, and baseline funnel, and you ship a production improvement.\nBy 60 days, you own a full experiment from problem definition through measurement and can explain the result.\nBy 90 days, you run a reliable experiment cadence and have improved a meaningful activation, conversion, retention, or reliability metric.\nEvidence we need to see\nTwo production products or features with your exact scope and technical ownership.\n\nOne product or growth experiment with a measured result.\n\nA clear example of an architecture, reliability, security, or incident tradeoff.\n\nA concrete AI development workflow, including tests and human review.\n\nEvidence that you can move from an ambiguous user problem to a stable production result.\n\nThis role is not\nA ticket-only implementation role.\n\nA role for shipping AI-generated code without tests or review.\n\nA research-only seat with no production ownership.\n\nA role that optimizes speed while ignoring users, reliability, or measurable outcomes.\n\nHow the process works\nApplication and evidence review.\n\nA focused product and engineering screen.\n\nThe published Beat Claude engineering challenge.\n\nA live review of your solution, tradeoffs, and validation plan.\n\nReferences and final decision.\n\nWork model and compensationThis role is fully remote. State your location, time-zone overlap, start date, and compensation expectations. Current benefits listed for the role will be preserved after employment type is confirmed.\nOriginally posted on Himalayas","description_format":"text","description_chars":3499,"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":[],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Sales & Marketing","Search Engine Optimization (SEO)","Creative Agencies"],"lifecycle":[{"event":"open","at":"2026-10-30T23:28:01Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":2,"expected_fill_days":27,"reasons":["seen:2","velocity","win:early"],"computed_at":"2026-11-02T06:13:15Z"},"pay":null,"html_url":"https://alion.io/job/single-grain-fullstack-product-engineer","json_url":"https://alion.io/job/single-grain-fullstack-product-engineer.json","meta":{"generated_at":"2026-11-02T16:08:59Z","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":22529,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-03T00:00:00Z"}},"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":52053},"rest":"https://alion.io/mcp/rest/get_company?id=52053"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fsingle-grain-fullstack-product-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%2Fsingle-grain-fullstack-product-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%2Fsingle-grain-fullstack-product-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/single-grain-fullstack-product-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fsingle-grain-fullstack-product-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3553456}},{"tool":"search_jobs","arguments":{"company":"singlegrain.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3553456},"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.
