This is a hands-on role. You’ll write infrastructure code, pipelines and backend code yourself, and report to the CEO and the Engineering Lead.\n\nScaling and security carry equal weight. Full details of our environment are shared with shortlisted candidates at interview.\n\nWhat you’ll own\n\nCloud platform and scalability\n\nDesign and run our cloud environment: projects, access management, networking, compute, managed databases, caching and messaging.\n\nSet up autoscaling, connection pooling, caching and queue-based workloads so the platform handles sudden traffic spikes.\n\nKeep cloud costs visible through budgets, rightsizing and capacity planning.\n\nSecurity tooling and hardening\n\nOwn and extend our security tooling across code, pipelines, cloud, edge, APIs and mobile apps, and run it as part of everyday engineering.\n\nTriage findings, fix the critical ones yourself and coach engineers through the rest.\n\nHarden authentication, sessions, integrations and transaction flows against fraud and abuse.\n\nEnforce least-privilege access, strong authentication and proper secrets management across the team.\n\nCode and architecture scalability\n\nReview backend services for scaling problems such as inefficient queries, missing indexes and slow synchronous work.\n\nRun load tests, find the breaking points and fix them in code alongside the backend team.\n\nSet engineering standards for service boundaries, async messaging, idempotency and database migrations.\n\nCI/CD and infrastructure as code\n\nMove all infrastructure into code, with reviewed changes and no manual changes in the console.\n\nBuild CI/CD pipelines covering build, test, security gates, staging, production and rollback.\n\nObservability and incident response\n\nRun logging, monitoring and error tracking. Define SLOs, alerts and security detections.\n\nOwn backups, disaster recovery drills and the incident response runbook, and take part in a light on-call rota.\n\nWhat we’re looking for\n\nMust have\n\n4+ years in platform, DevOps, SRE or backend roles, with at least 3 years running production systems on a major cloud provider (Google Cloud preferred).\n\nStrong infrastructure-as-code and CI/CD skills (for example Terraform and GitHub Actions).\n\nContainers in production, including image hardening.\n\nAble to read and change Node.js/TypeScript backend code.\n\nRelational database performance work: query plans, indexing, connection pooling and replicas.\n\nHands-on security work: secrets management, least-privilege access, code, dependency and container scanning, and the OWASP Top 10, especially authorization flaws.\n\nLoad testing and capacity planning, with real numbers to show for it.\n\nClear written communication. You’ll write runbooks and explain risk to non-engineers.\n\nBSc in Computer Science, IT or a related field, or an equivalent professional qualification.\n\nNice to have\n\nWeb and API security testing tools, including writing custom scanning rules.\n\nWAF, rate-limiting and bot-protection configuration.\n\nMessage queues and caching at scale.\n\nMobile app security, or securing payment integrations.\n\nCertifications such as Google Professional Cloud Security Engineer, Professional Cloud Architect or CKS.\n\nStartup experience in consumer platforms or e-commerce.\n\nHow to apply\n\nSend your CV and a short note to . In your note, tell us about one scaling or security problem you found and fixed, and what difference it made.","description_format":"text","description_chars":3606,"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":[],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-28T05:18:00Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":3,"expected_fill_days":24,"reasons":["seen:3","win:early"],"computed_at":"2026-10-31T05:58:55Z"},"pay":null,"html_url":"https://alion.io/job/mo-marketplace-platform-security-engineer","json_url":"https://alion.io/job/mo-marketplace-platform-security-engineer.json","meta":{"generated_at":"2026-10-31T23:49:33Z","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":37325,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-01T00:00:00Z"}},"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":4481613},"rest":"https://alion.io/mcp/rest/get_company?id=4481613"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fmo-marketplace-platform-security-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%2Fmo-marketplace-platform-security-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%2Fmo-marketplace-platform-security-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/mo-marketplace-platform-security-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fmo-marketplace-platform-security-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3381188}},{"tool":"search_jobs","arguments":{"company":"mo.lk","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3381188},"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.
