New startups can use our hosted pre-built UIs which provide the simplest possible integration. Out of the box, our customers immediately have the same auth experience as large tech companies like Slack. As those startups grow, they can use our APIs and component libraries to pull aspects of the experience into their product.\nWe’re also working on auth for AI products and MCP servers. As agents start accessing data and taking actions on behalf of users, developers need to know which user and organization an agent represents, what it’s allowed to do, and how that access can be revoked. It’s a new version of the same problem we’ve always worked on: making powerful authorization models easy for developers to use.\nAbout the role\nWe pride ourselves on shipping code frequently and learning as we go. We also have critical security, performance, and uptime requirements, so finding the right ways to ship frequently within those requirements is very important.\nWe all love to learn and grow. Our leadership team has experience working with and mentoring engineers at both startups and top companies. We'll work with our hires to craft this role to their interests, skill set, and long term career goals.\nIf you’re passionate about building products that make a complex problem easy for your end users, this job is for you. As part of a small team, you’ll have the opportunity to shape both the product and the engineering culture.\nResponsibilities:\nOur core product is written in React /Typescript and allows our users to create configurable, but complex auth experiences. You will own both our customer's experience AND their users' authentication experiences.\nOur backend is written in Rust with a few parts in Python\nBuild configurable UIs / component libraries that can be embedded into our customers products. There's a lot of room to be experimental here and make delightful experiences for our customers' users.\nBuild client libraries in a variety of different frameworks like React, React Native, Vue, and Svelte\nLearn and support new auth standards like MCP or biometrics support\nBe creative! In addition to auth, we want to provide our customers with all the tools they need to be successful. As a small team, we like supporting our employees ideas.\nWork with our Support team to understand the needs of our users\nWhat we look for from you:\n3+ years engineering experience\nExperience working independently on small teams\nExcited to build products that customers love\nAbility to move quickly, but carefully\nExperience with authentication or security appreciated but not required\nWorking With Us:\nWe're a remote-first team, spread over the US. Working hours are flexible but we ask that you have 4-5 hours of overlap with 9am-5pm PST\nWe provide standard benefits - health insurance, PTO, etc\nWe strongly believe in hiring employees that are experts at what they do, and that our job is to support each other","description_format":"text","description_chars":3020,"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":["Health insurance"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Identity Management","Developer Tools"],"lifecycle":[{"event":"open","at":"2026-09-03T14:41:23Z"}],"visa":[],"liveness":{"score":10,"band":"cold","label":"Long shot","p_open":1,"p_active":0.28,"p_room":0.35,"age_days":49,"expected_fill_days":7,"reasons":["conf:0","win:tail"],"computed_at":"2026-10-23T05:54:15Z"},"pay":{"stated_usd_annual":180000,"is_top_pay":false},"html_url":"https://alion.io/job/propelauth-fullstack-engineer","json_url":"https://alion.io/job/propelauth-fullstack-engineer.json","meta":{"generated_at":"2026-10-23T13:37:06Z","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":20334,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-24T00:00:00Z"}},"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":58752},"rest":"https://alion.io/mcp/rest/get_company?id=58752"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fpropelauth-fullstack-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%2Fpropelauth-fullstack-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%2Fpropelauth-fullstack-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/propelauth-fullstack-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fpropelauth-fullstack-engineer"}]}
