The Infra Agent Systems team builds the software systems that power and automate that infrastructure.\nWe develop production AI agents that diagnose hardware failures, investigate incidents, correlate signals across the fleet, and automate operational workflows. Alongside these agents, we build the platform they run on, including knowledge graphs, retrieval systems, orchestration frameworks, and developer tooling.\nYou’ll work across two areas:\nInfrastructure Agent Systems - Build production AI agents that help operate our GPU fleet by diagnosing failures, investigating incidents, gathering evidence from live systems, and assisting with remediation. These agents are used every day by our infrastructure and datacenter teams through APIs, CLI, dashboards, and Slack.\nCore Agent Platform - Build the platform that powers these agents, including knowledge graphs, search and retrieval, orchestration, evaluation, and the tooling that enables agents to reason, act, and continuously improve.\nWe’re working on something that hasn’t really been done before: building knowledge graphs and self-improving AI agents that understand, operate, and continuously improve large-scale AI infrastructure.\nThis is an opportunity to work at the intersection of AI agents, distributed systems, infrastructure, and automation, solving challenging engineering problems with real production impact. There’s an enormous amount to build, learn, and shape as we define the future of autonomous infrastructure.\nresponsible for delivering the software but also for operating and supporting it in production.\nWhy this Role\nYou’ll work on two hard problems at the same time: making AI agents trustworthy enough to operate production infrastructure, and building the knowledge, retrieval, and distributed systems that make those agents effective.\nYou’ll have the opportunity to build foundational systems from the ground up, work on infrastructure at massive scale, and help define how self-improving AI agents operate real-world AI infrastructure.\nHybrid in Amsterdam\n Responsibilities\nDesign and build production AI agent systems that diagnose, investigate, and remediate infrastructure issues across one of the world’s largest GPU fleets.\nBuild the distributed services, orchestration framework, knowledge graph, and retrieval systems that power infrastructure agents.\nDevelop fleet intelligence systems that combine telemetry, infrastructure state, operational knowledge, and historical incidents to help agents make better decisions.\nIntegrate with observability, incident management, ticketing, fleet inventory, source control, chat, and internal infrastructure systems through well-designed APIs.\nOwn services end to end, including architecture, implementation, testing, deployment, observability, and production operations.\nImprove agent performance through evaluations, retrieval improvements, better tools, and production feedback loops.\nTurn what agents learn in production into reliable, reviewed software and automation.\nRequirements\n5+ years of experience building production backend systems, distributed systems, or infrastructure platforms.\nStrong systems design skills and experience owning significant systems from design through production.\nDepth in at least one of the following:\nAI agent systems, orchestration, tool use, evaluation, or grounding\nKnowledge graphs or graph data modeling\nSearch, retrieval, ranking, RAG, or semantic search systems\nStrong backend engineering experience, including API design, service boundaries, data modeling, and integrations across complex systems.\nExperience with Kubernetes, GitOps such as ArgoCD, infrastructure-as-code, and cloud platforms.\nComfortable working across languages such as Go, TypeScript, Python, or Rust.\nExperience in the following is a plus:\nGPU infrastructure, datacenters, bare-metal systems, hardware failure modes, BMC/IPMI, or cluster schedulers\nGraph databases\nEvent-driven systems and messaging platforms such as NATS or Kafka\nObservability platforms such as Prometheus and Grafana\nBuilding evaluation frameworks or improving the quality and reliability of LLM-powered systems\nAbout Together AI\nTogether AI, the AI Native Cloud, is purpose-built for AI engineers. AI application developers get high-performance inference that scales reliably, fine-tuning and reinforcement learning for creating frontier-level specialized models, and pre-training at massive scale for fully custom intelligence, all around a marketplace of leading open models that teams can run, adapt, and own. Trusted by Cursor, Decagon, ElevenLabs, Salesforce, and Zoom, Together serves 400+ trillion tokens a month.\nEqual Opportunity\nTogether AI is an Equal Opportunity Employer and is proud to offer equal employment opportunity to everyone regardless of race, color, ancestry, religion, sex, national origin, sexual orientation, age, citizenship, marital status, disability, gender identity, veteran status, and more.\nPlease see our privacy policy at https://www.together.ai/privacy.","description_format":"text","description_chars":5092,"description_truncated":false,"requirements":{"experience_years_min":5,"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":["Cloud Platforms (IaaS & PaaS)","Foundation Models","AI Compute & Inference"],"lifecycle":[{"event":"open","at":"2026-09-06T17:45:23Z"}],"visa":[],"liveness":{"score":62,"band":"ok","label":"Likely open","p_open":1,"p_active":0.824,"p_room":0.75,"age_days":52,"expected_fill_days":55,"reasons":["conf:4","velocity","win:late"],"computed_at":"2026-10-29T05:49:05Z"},"pay":null,"html_url":"https://alion.io/job/together-ai-senior-software-engineer-infra-agent-systems","json_url":"https://alion.io/job/together-ai-senior-software-engineer-infra-agent-systems.json","meta":{"generated_at":"2026-10-29T10:14:32Z","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":15441,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-30T00:00:00Z"}},"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":36054},"rest":"https://alion.io/mcp/rest/get_company?id=36054"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ftogether-ai-senior-software-engineer-infra-agent-systems"},{"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%2Ftogether-ai-senior-software-engineer-infra-agent-systems"},{"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%2Ftogether-ai-senior-software-engineer-infra-agent-systems"},{"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/together-ai-senior-software-engineer-infra-agent-systems\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ftogether-ai-senior-software-engineer-infra-agent-systems"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":483047}},{"tool":"search_jobs","arguments":{"company":"together.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":483047},"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.
