It underwrites the middle class and is the mechanism through which millions of families build wealth. But while every other financial instrument has been simplified to an API call, mortgages are still assembled by hand.\nWe started from zero and created the first vertically integrated mortgage platform that turns origination into a single API.\nPublicly traded companies and the country’s largest originators are already building on Pylon. Revenue is compounding monthly. We’re backed by Peter Thiel, Conversion Capital, QED, Citi, Fifth Wall, and the founders of Ramp, Blend, and Mercury.\nWorking at Pylon isn’t for those seeking comfort. The people who thrive here have high agency, strong opinions, and a track record of delivering outcomes without direction. Many of us are former founders. We move quickly, challenge each other directly, and take full ownership of results. It’s hard work, but it will be worth it.\nJoin us in buildingAmerica’s mortgage rails.\nThe Team\nWe're looking for Infra Engineers to join our Foundation team. This team keeps the platform stable and the developers productive. That's it. Two jobs, both critical.\nWe'll be honest: we're scaling fast, and our infrastructure needs to keep up. We need people who've seen systems under pressure and know how to make them reliable - not just \"works on my machine\" reliable, but \"processes millions of dollars in mortgage transactions\" reliable.\nYour customers aren't borrowers - they're the engineers sitting next to you. When you make deploys faster, monitoring clearer, or incidents rarer, the entire company ships better software. The feedback loop is instant: your teammates will tell you, loudly, when something is great or when something is broken.\nHere Is What You'll Do\nKeep highly available systems highly available. We process mortgage transactions that can't go down. You'll design, monitor, and improve the infrastructure that makes that possible.\n\nMake developers more productive. Slow builds, flaky tests, painful deploys - these are your enemies. You'll build tooling and infrastructure that lets the rest of the team move fast with confidence.\n\nBe a groundskeeper of the codebase. You'll help maintain code quality, teach best practices, and mentor junior engineers. The Foundation team sets the standard for how we build software.\n\nFight fires and prevent them. When something breaks, you'll help fix it. More importantly, you'll build the systems and practices that keep things from breaking in the first place.\n\nWork with instant feedback. Your customers are your coworkers. They'll tell you what's working and what's not - no surveys, no quarterly reviews, just direct, honest feedback every day.\n\nTech Stack\nAWS (our cloud home)\n\nTypeScript\n\nGraphite (stacked PRs and developer workflow)\n\nHoneycomb (observability)\n\nGitHub Codespaces (development environments)\n\nTemporal.io (workflow orchestration)\n\nSQL (PostgreSQL)\n\nGraphQL\n\nAI-driven development tooling and agentic infrastructure\n\nWho Will Succeed Here\nSomeone who:\nIs deeply curious\n\nWants to won features from design to development to deployment to maintence\n\nIs willing to put the work in to solve the hardest of problems\n\nLocation: Palo Alto , CA Base Salary Range: $140,000/yr to $220,000/yr + Equity + Benefits","description_format":"text","description_chars":3367,"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"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Financial Software & Embedded Finance","Mortgage Lending & Brokers"],"lifecycle":[{"event":"open","at":"2026-09-13T11:11:36Z"}],"visa":[],"liveness":{"score":4,"band":"cold","label":"Long shot","p_open":1,"p_active":0.15,"p_room":0.28,"age_days":207,"expected_fill_days":28,"reasons":["conf:3","velocity","win:tail","crowd:"],"computed_at":"2026-11-07T05:47:08Z"},"pay":{"stated_usd_annual":220000,"is_top_pay":true},"html_url":"https://alion.io/job/pylonlending-infrastructure-engineer-foundation","json_url":"https://alion.io/job/pylonlending-infrastructure-engineer-foundation.json","meta":{"generated_at":"2026-11-08T02:29:10Z","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":5307,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-09T00:00:00Z"}},"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":695239},"rest":"https://alion.io/mcp/rest/get_company?id=695239"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fpylonlending-infrastructure-engineer-foundation"},{"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%2Fpylonlending-infrastructure-engineer-foundation"},{"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%2Fpylonlending-infrastructure-engineer-foundation"},{"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/pylonlending-infrastructure-engineer-foundation\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fpylonlending-infrastructure-engineer-foundation"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":862665}},{"tool":"search_jobs","arguments":{"company":"pylonlending.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":862665},"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.
