You’ll work closely with founders, product, and security experts to turn messy real-world Security operations like SOC, ThreatHunt, Pentest, Security device management etc. into elegant, scalable product experiences. You may own one vertical deeply or work across several in the same project when needed. In your first few months, you will:Own end-to-end design & delivery of features you take up\nShip platform, agent, or integration capabilities at high velocity\nCollaborate not just with product & engineering leaders, but also sales, marketing, and customer-facing teams to shape what we build and why\nDeploy features into live production environments, with ownership beyond delivery - including monitoring, stability, and iteration post-launch What You’ll Work On Your work may include: AI + Agent Systems\nBuilding agents for SecOps → Develop autonomous agents that investigate alerts, triage threats, respond, and close cases with minimal human input.\nDesigning tool schemas, workflows, memory stores for agents → Define structured tool interfaces, execution paths, and long-term memory for reasoning across tasks.\nLangGraph based flows for agents (or another agentic framework) → Build multi step agent workflows with branching logic, retries, validation, and conditional tool calling.\nSafe-execution loops with guardrails, policy layers, and approvals → Ensure agents operate within risk boundaries using policy controls and human-review checkpoints. Platform & Architecture\nBuilding high-scale, multi-tenant backend systems→ Architect services that securely support many customer environments in parallel without resource collisions.\nDesigning ingestion, indexing & agent memory retrieval layers → Build pipelines that ingest customer security data, store it as agent-accessible memory, and retrieve relevant context instantly.\nImplementing evaluation pipelines & scoring frameworks for agents → Measure agent quality using scoring metrics, test harnesses, regressions, and continuous feedback signals.\nDistributed execution, traceability, observability & data quality → Enable high volume workloads with strong logging, metrics, monitoring, and correctness guarantees. Security & Product Engineering\nReal-time incident lifecycle automation end-to-end → Automate detection → enrichment → investigation → response with minimal human touch.\nAttack simulation & golden dataset creation → Generate controlled attack scenarios to evaluate agents and build benchmark datasets for continuous improvement.\nSIEM, SOAR, EDR, NDR style integrations → Integrate with enterprise security products, ingest telemetry, push remediation actions, and unify signals across the stack. This is a place where engineers ship, own, iterate, observe, and improve.\nRequirements You’ll Thrive Here If You\nThink in systems\nLike solving undefined problems, not following tickets\nUnderstand distributed systems + AI fundamentals deeply\nEnjoy reading RFCs, research papers & learning new tech Must Have\nStrong backend development experience (Python/Go/Node preferred)\nSolid understanding of distributed systems fundamentals\nExperience with microservices, async execution, event streams\nFamiliarity with cloud infra (AWS/GCP/Azure), containers, CI/CD\nOwnership mindset - ability to take a problem from zero → shipped Bonus / Great to Have\nWorked on SIEM, SOAR, EDR platforms OR cyber security data pipelines\nKnowledge of RAG, vector DBs, embeddings, Eval frameworks\nLangChain / LangGraph / agent implementations\nObsessed with writing clean tests, docs, and elegant abstractions PS: WE ARE VERY PARTICULAR ABOUT YOUR PEDIGREE. WE WILL PREFER IF YOU HAVE STUDIED FROM IIT'S, BIT'S, VIT, AND NIT\nBenefits Why Join Us?\nBuild an AI-first SOC platform from scratch\nWork directly with founders/leaders on architecture, product direction.\nShip fast, learn fast, own deeply\n• Be there early - where impact compounds","description_format":"text","description_chars":4106,"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":[],"hiring_locations":[{"name":"India","iso":"IN","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Artificial Intelligence","Cybersecurity","AI Agents"],"lifecycle":[{"event":"open","at":"2026-09-07T08:31:15Z"},{"event":"open","at":"2026-09-20T06:00:00Z"}],"visa":[],"liveness":{"score":13,"band":"cold","label":"Long shot","p_open":1,"p_active":0.364,"p_room":0.35,"age_days":113,"expected_fill_days":37,"reasons":["conf:3","win:tail"],"computed_at":"2026-10-28T05:59:10Z"},"pay":null,"html_url":"https://alion.io/job/simbian-full-stack-engineer-backend-heavy","json_url":"https://alion.io/job/simbian-full-stack-engineer-backend-heavy.json","meta":{"generated_at":"2026-10-28T22:22:35Z","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":30303,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-29T00:00:00Z"}},"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":177904},"rest":"https://alion.io/mcp/rest/get_company?id=177904"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fsimbian-full-stack-engineer-backend-heavy"},{"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%2Fsimbian-full-stack-engineer-backend-heavy"},{"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%2Fsimbian-full-stack-engineer-backend-heavy"},{"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/simbian-full-stack-engineer-backend-heavy\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fsimbian-full-stack-engineer-backend-heavy"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":498553}},{"tool":"search_jobs","arguments":{"company":"simbian.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":498553},"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.
