Today, that operating scope is delivered through a mix of people, software, and AI. We're building the technology to handle more of that work autonomously, without turning into another tool customers have to supervise.\nWe're looking for a Backend / Systems Engineer to build the software that makes this reliable: persistent state, safe execution, permissions, and recovery across humans, agents, and external systems.\nTasks\nWhat You'll Own\nData models & state: Build backend services and data models that track operational work, ownership, and outcomes over time.\nAsynchronous workflows: Develop asynchronous workflows with reliable handling of retries, timeouts, external events, and interrupted execution.\nAPIs & tool execution: Build shared APIs and tool-execution interfaces, including authorization and customer-data isolation.\nKnowledge infrastructure: Improve the infrastructure for storing, versioning, and serving operational knowledge.\nPlatform quality: Strengthen testing and observability while evolving the existing platform alongside our CTO, AI engineer, and product engineering team.\nRequirements\nWhat Makes You a Great Fit\nStrong backend engineering skills in Python and/or TypeScript/Node.js, with willingness to work across both.\nPractical experience with PostgreSQL or another relational database, including data modeling and transactions.\nExperience shipping and maintaining production backend services.\nFamiliarity with background jobs, queues, or event-driven processing, and an understanding of failure handling and data consistency.\nThe ability to investigate production problems, design clear interfaces, and deliver maintainable solutions.\nAround 3+ years of backend engineering experience is a useful guide, not a hard requirement. The systems you've owned matter more than the number.\nNice to have: experience with workflow engines, multi-tenant applications, authorization, FastAPI, or agent tooling. Prior LLM experience is not required. Strong backend fundamentals and an interest in learning the agent domain matter more.\nYou May Not Be a Great Fit If\nYou want to configure infrastructure, not design the systems underneath it.\nYou need a fully scoped spec instead of investigating ambiguous problems yourself.\nYou've never shipped and maintained a production backend service.\nYou favor clever or complex solutions over simple, maintainable ones.\nYou're looking for a defined 9-to-5.\nBenefits\nWhy Join xHeron\nReal ownership: you're working on foundational product architecture, not cloud configuration, with substantial technical ownership from day one.\nDirect founder access: you'll work directly with our CTO, shaping how humans and agents work together.\nWe invest in our own: your ownership grows as the system does, this isn't a role with a ceiling.\nUpside: VSOP alongside salary; you're building this with us.\nOur Process\nIntro call (30 min): a conversation with Friedrich (CTO) about your background, what you've built, and why this role.\nTechnical take-home case study: a short, real engineering problem, close to what you'd actually be building.\nCase study interview (1 hour): you walk us through your thinking, not just the final code.\nCulture fit (30 min): meet both Founders and make sure it's a fit both ways.","description_format":"text","description_chars":3397,"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":["Hotels & Resorts"],"lifecycle":[{"event":"open","at":"2026-09-15T08:33:47Z"}],"visa":[],"liveness":{"score":48,"band":"ok","label":"Likely open","p_open":1,"p_active":0.638,"p_room":0.75,"age_days":23,"expected_fill_days":28,"reasons":["conf:1","win:late"],"computed_at":"2026-10-08T05:49:30Z"},"pay":null,"html_url":"https://alion.io/job/xheron-backend-systems-engineer-agent-infrastructure-mfx","json_url":"https://alion.io/job/xheron-backend-systems-engineer-agent-infrastructure-mfx.json","meta":{"generated_at":"2026-10-09T03:01:03Z","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","counted_by":"address","units_charged":1,"used_today":1370,"day_limit":5000,"remaining_today":3630,"minute_limit":60,"resets_at":"2026-10-10T00:00:00Z"}},"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":689342},"rest":"https://alion.io/mcp/rest/get_company?id=689342"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fxheron-backend-systems-engineer-agent-infrastructure-mfx"},{"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%2Fxheron-backend-systems-engineer-agent-infrastructure-mfx"},{"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%2Fxheron-backend-systems-engineer-agent-infrastructure-mfx"},{"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/xheron-backend-systems-engineer-agent-infrastructure-mfx\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fxheron-backend-systems-engineer-agent-infrastructure-mfx"}]}
