Enterprise AI adoption has made identity the fastest-growing attack surface, and the hardest to govern. Josys discovers, governs, and secures every identity - human, machine, and AI agent - across every application in the enterprise, allowing security and IT teams to surface risk, control access, and remediate identity threats in real-time. Trusted by over 1,000 organizations and MSPs worldwide, Josys turns identity from the fastest-growing attack surface into an autonomously governed advantage.

This is not a Rails-only role - the ideal candidate is someone who is strong in Rails but equally comfortable working across our broader backend stack (Node.js, microservices, and other services), and can move fluidly between them based on what the team needs. The successful candidate will be responsible for developing and maintaining the back-end infrastructure of our B2B SaaS product, with a strong understanding of software architecture, database design, and server-side programming. Additionally, the candidate should have experience working with cloud-based infrastructure (AWS, preferably) and be able to develop highly scalable and secure systems.\nKey Responsibilities\nCollaborate with the development team, product managers, and designers to understand business requirements and contribute to technical specifications and software solutions.\n\nDesign, develop, test, and deploy back-end components across our Ruby on Rails and non-Rails (e.g. Node.js) services - this role is expected to work across the backend stack, not within a single framework.\n\nWork with front-end engineers to develop APIs that facilitate smooth data flow and system interoperability.\n\nContribute to system design discussions, weighing in on architecture, scalability, and trade-offs for new and existing services.\n\nOptimize code, conduct testing, and follow best practices to ensure the reliability, performance, and security of the application.\n\nLearn and contribute to the development and maintenance of cloud-based infrastructure, preferably using AWS, ensuring scalability, high availability, and disaster recovery.\n\nUse AI-assisted development tools (e.g. Cursor or similar) thoughtfully as part of the engineering workflow - going beyond surface-level usage to actually improve code quality, review rigor, and team productivity.\n\nCollaborate with cross-functional teams to ensure successful product launches and provide support when needed.\n\nParticipate actively in Agile development practices, including sprint planning, stand-ups, and retrospectives.\n\nContribute to the refinement of user stories, provide effort estimations, and prioritize tasks to ensure timely delivery.\n\nParticipate in code reviews to maintain code quality, receive constructive feedback, and adhere to best practices.\n\nStay updated with industry trends and emerging technologies, evaluating their potential benefits for the product and the development team.\n\nActively contribute to continuous improvement initiatives by suggesting process enhancements and implementing approved changes.\n\nRequirements / Qualifications\n3-7 years of backend development experience, with strong, hands-on Ruby on Rails expertise. Exceptionally strong candidates with ~2 years of experience will also be considered.\n\nDemonstrated ability and willingness to work across multiple backend services/frameworks (e.g. Rails and Node.js) - candidates seeking a Rails-only scope are not a fit for this role.\n\nStrong IC (individual contributor) who can join any existing project and start contributing within a week's time.\n\nCan build and integrate REST APIs in Rails.\n\nExperience working with async processors such as Sidekiq, Resque, ActiveJob, or Shoryuken.\n\nSolid understanding of Rails object-oriented programming concepts.\n\nComfortable engaging in system design discussions - able to reason through architecture, scale, and trade-offs, not just implement to spec.\n\nGenuine, hands-on experience using AI tools in development - able to speak concretely to workflow, prompting practices, code review process with AI-assisted code, and problems solved (not just familiarity with a tool name).\n\nAbility to speak in depth about past project ownership - real depth of involvement matters more than breadth listed on a resume.\n\nFamiliarity with front-end technologies such as HTML, CSS, and JavaScript is a plus.\n\nExposure to cloud-based infrastructure, preferably AWS services, and a strong desire to learn about scalable and secure system development.\n\nEffective problem-solving in ambiguous and complex technical scenarios.\n\nStrong computer science fundamentals and automation testing technologies.\n\nFocus on customer satisfaction and holistic user experience.\n\nExcellent communication, collaboration, and mentoring abilities.","description_format":"text","description_chars":5008,"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":["IT Service & Asset Management"],"lifecycle":[{"event":"open","at":"2026-09-11T01:17:06Z"}],"visa":[],"liveness":{"score":28,"band":"fade","label":"Fading","p_open":1,"p_active":0.764,"p_room":0.36,"age_days":149,"expected_fill_days":94,"reasons":["conf:2","win:tail","crowd:"],"computed_at":"2026-11-02T06:13:15Z"},"pay":null,"html_url":"https://alion.io/job/josys-senior-backend-engineer","json_url":"https://alion.io/job/josys-senior-backend-engineer.json","meta":{"generated_at":"2026-11-03T05:32:07Z","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":7593,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-04T00:00:00Z"}},"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":678518},"rest":"https://alion.io/mcp/rest/get_company?id=678518"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fjosys-senior-backend-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%2Fjosys-senior-backend-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%2Fjosys-senior-backend-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/josys-senior-backend-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fjosys-senior-backend-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":692441}},{"tool":"search_jobs","arguments":{"company":"josys.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":692441},"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.
