Our platform lets growth teams run their entire go-to-market motion in one place, from acquisition through retention, with AI agents doing the work that legacy tools like Marketo, HubSpot, and Pardot can't.\nWe've raised $28M+ from Abstract Ventures, True Ventures, and HOF Capital. The team is based in San Francisco and includes engineers, designers, and operators from Airbnb, Palantir, Pinterest, IMC, Shopify, LinkedIn, and Microsoft.\nAbout the Role\nHey there! James here , co-founder and CTO at Conversion. Just wanted to share my thoughts on the perfect candidate we're looking to join our engineering team.\nFirst off, I want to stress the technical difficulty and scale of what we're building here at Conversion. The reason marketing automation platforms haven't seen a new player in decades is because building one is hard. Our platform needs to handle terabytes of data syncs per customer with the utmost reliability, coordinate complex workflows that automate mission critical go-to-market processes, handle form submissions that directly generate revenue for customers, and serve high delivering emails to millions of our customer's recipients.\nHere's what we're looking for in an infrastructure engineer to join our core team:\nEngineer multiplier: Your customers are our product engineers. The goal is to unlock and empower them to ship features faster and more reliably for our customers. The best infra work here is measured in how much leverage you give the rest of the team.\n\nPragmatic optimizer: Over-optimizing is a real thing. As a startup, our goal is to grow and build an amazing product that delivers value, not to needlessly upgrade our tech stack for the sake of it. Your job is to strike the line between the cost of infrastructure changes and the potential benefits. Everything's a tradeoff and we want to take the worthwhile ones.\n\nIntellectually curious: Conversion engineers are the kind of people who get excited about a weird edge case and end up sending five Slack messages about it before lunch.\n\nThis role is in-person 5 days/week in San Francisco.\nYou Might Be a Good Fit If You\nHave 3+ years of experience building cloud infrastructure, dev tooling, and platform systems at fast-growing companies\n\nHave shipped and operated systems that other engineers depend on, including CI/CD, observability, deploy tooling, or internal platforms\n\nHave a startup mindset and want early ownership in a fast-paced environment\n\nHave experience with our tech stack:\nGo for backend services\n\nKafka for large-scale data streaming\n\nTemporal for durable job execution\n\nPostgreSQL and ClickHouse as our databases\n\nGCP for cloud hosting\n\nYou Might Be a Great Fit If You\nHave built internal developer tools or platforms that meaningfully changed how a team shipped\n\nHave worked at a Series A to C startup that scaled quickly\n\nHave a strong track record of side projects, apps, or hackathons. Our engineers have built a live-streaming security system for their parents' new house, a database from scratch, a better Splitwise app, and hosted our Minecraft server, all while at Conversion\n\nUseful links\nWebsite: https://conversion.ai/\n\nCareers: https://conversion.ai/careers\n\nNext Play article on our team: https://nextplayso.substack.com/p/how-a-big-pivot-helped-this-company\n\nEngineering blog: https://conversion.ai/blog","description_format":"text","description_chars":3473,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["E-commerce Marketing","A/B Testing & Experimentation"],"lifecycle":[{"event":"open","at":"2025-09-27T01:24:53Z"},{"event":"open","at":"2026-09-26T01:13:14Z"}],"visa":[],"liveness":{"score":7,"band":"cold","label":"Long shot","p_open":1,"p_active":0.236,"p_room":0.28,"age_days":385,"expected_fill_days":32,"reasons":["conf:0","velocity","win:tail","crowd:"],"computed_at":"2026-10-17T05:46:00Z"},"pay":{"stated_usd_annual":225000,"is_top_pay":true},"html_url":"https://alion.io/job/conversion-backend-engineer-infra","json_url":"https://alion.io/job/conversion-backend-engineer-infra.json","meta":{"generated_at":"2026-10-17T06:42:07Z","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":9135,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-18T00:00:00Z"}},"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":7266},"rest":"https://alion.io/mcp/rest/get_company?id=7266"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fconversion-backend-engineer-infra"},{"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%2Fconversion-backend-engineer-infra"},{"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%2Fconversion-backend-engineer-infra"},{"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/conversion-backend-engineer-infra\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fconversion-backend-engineer-infra"}]}
