We're coming up with solutions in a problem space where no one in Silicon Valley knows the answer to either: how to build something agents want. If you like owning things 0 -> 1, lets chat.\nAgentMail is building an API designed to give inboxes to AI agents and be the sole identity + communication provider. It isn't AI for your email, it's email for your AI.\nWe’re looking for a founding engineer with strong backend and infra instincts to help build the primitives agents will use to communicate, authenticate, and operate in the real world. This is a role for someone who likes systems work: APIs, distributed infrastructure, reliability, developer tooling.\nCompany highlights:\nWorld-Class Team: Founded by a team of experts in their own respects(Quant, SWE, Private Equity), the team has top-tier talent from startups and big companies alike, with backgrounds from Optiver, NVIDIA, Amazon, Modern Treasury, KKR.\n\nHypergrowth: We’ve doubled our user count every 2 weeks since January, and don’t plan on slowing down any time soon. As agents will outnumber humans very soon, we see this multiple changing in the range of orders very soon.\n\nCompetitive-edge: We are the sole identity provider for agents. Just like you have a Gmail, agent’s will need an AgentMail.\n\nWhat you’ll do\nDesign APIs and abstractions that are intuitive for both humans and AI Agents\n\nBuild high-performant, low-latency systems with the idea that agents are the end-users in mind\n\nGet your hands dirty by touching our core infrastructure that processes hundreds of thousands of emails per day.\n\nThink creatively about being the bridge between cutting edge AI capabilities with something as primitive as email(an oxymoron we know)\n\nOwn projects end-to-end, from system design to production rollout\n\nWrite clear, maintainable code and strong technical documentation\n\nBe the frontline for feedback from our customers - we’ll trust you to be our spokesperson\n\nWhat we’re looking for\nYou want to solve problems end-to-end: every engineer owns a part of the product and needs to make decisions across the frontend, infrastructure, backend, and UX.\n\nYou have a high bar for quality: At a startup, speed is the only advantage we have over big-tech companies. But even more important is to care about your output and obsess about details.\n\nYou are a clear thinker and communicator: We have daily standups and weekly syncs in which we expect you to communicate tradeoffs, problems, and blockers directly.\n\nYou are highly technical: preferred you have prior experience shipping production software by real users as a software engineer at a tech company or startup. But hustlers are always appreciated.\n\nBonus points\nExperience with cloud infrastructure, distributed systems, or developer tools\n\nExperience with messaging, email, auth, or protocol-heavy systems\n\nExperience building for AI/LLM use cases\n\nCompensation\n$150k - $250k base\n\n0.5% - 1.5% equity\n\nMedical, dental, and vision insurance\n\nAll employees get Equinox memberships\n\nBreakfast, lunch, and dinner (Free Doordash)","description_format":"text","description_chars":3254,"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","Vision insurance"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["AI Agents","Email Hosting & Delivery"],"lifecycle":[{"event":"open","at":"2026-09-11T18:36:36Z"},{"event":"open","at":"2026-09-25T15:17:56Z"}],"visa":[],"liveness":{"score":5,"band":"cold","label":"Long shot","p_open":1,"p_active":0.18,"p_room":0.28,"age_days":236,"expected_fill_days":30,"reasons":["conf:2","win:tail","crowd:"],"computed_at":"2026-11-01T06:10:25Z"},"pay":{"stated_usd_annual":250000,"is_top_pay":true},"html_url":"https://alion.io/job/agentmail-founding-engineer","json_url":"https://alion.io/job/agentmail-founding-engineer.json","meta":{"generated_at":"2026-11-01T10:12:41Z","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":15755,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-02T00:00:00Z"}},"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":669731},"rest":"https://alion.io/mcp/rest/get_company?id=669731"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fagentmail-founding-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%2Fagentmail-founding-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%2Fagentmail-founding-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/agentmail-founding-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fagentmail-founding-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":761288}},{"tool":"search_jobs","arguments":{"company":"agentmail.to","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":761288},"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.
