You'll work on the critical infrastructure that powers both our public API (used by external developers) and internal tools, managing user data, task orchestration, billing, permissions, and asset management.\nThis is a high-impact role on a mature, production system. You'll build enterprise features, optimize database performance, design async workflows, and ensure reliability at scale. If you're passionate about API development, love TypeScript, and want to own systems end-to-end, this is the role for you.\nA peek at our technical stack\nOur API endpoints for real-time collaboration and media asset management is written in TypeScript, and runs in ECS containers on AWS Fargate. We leverage multiple AWS-native components, such as S3, CloudFront, Lambda, Kinesis, and SQS, as building blocks of our infrastructure.\nOur inference backend is written in Python (PyTorch, TorchScript), and is deployed across multiple clusters / cloud providers. We use Kubernetes for container orchestration, and k8s-native components such as Flyte, Kueue, and Kyverno efficient job orchestration. We invest in prometheus and grafana for monitoring, and Terraform to manage our infrastructure.\nWhat you’ll do\nOwn the full API lifecycle from design and implementation to monitoring, optimization, and documentation for both public and internal APIs\n\nDesign and implement async workflows for task orchestration, content moderation, prompt enhancement, and post-processing pipelines\n\nOptimize database queries and improve performance for a high-traffic Postgres database\n\nBuild rate limiting, fraud detection, and credit management systems\n\nImplement comprehensive API security, rate limiting, authentication, and monitoring systems to ensure reliability at scale\n\nImprove the public API developer experience with better documentation, SDKs, and tooling\n\nImprove the performance, reliability, and code quality of our codebases\n\nWhat you’ll need\n3+ years of industry experience building production APIs\n\nStrong TypeScript experience, so you can jump in and be productive immediately\n\nExperience owning systems end-to-end: infrastructure, monitoring, logging, metrics, incident response\n\nUnderstanding of API design patterns, REST principles, and async workflows\n\nExperience with relational databases (Postgres preferred) and query optimization\n\nExperience architecting production-ready systems at scale using cloud primitives from AWS, GCP, or Azure\n\nAbility to rapidly prototype solutions and iterate on them with tight product deadlines\n\nHumility and open mindedness; we love to learn from one another","description_format":"text","description_chars":2761,"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":[{"name":"Canada","iso":"CA","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-23T05:34:23Z"}],"visa":[],"liveness":{"score":54,"band":"ok","label":"Likely open","p_open":1,"p_active":0.542,"p_room":1,"age_days":1,"expected_fill_days":28,"reasons":["conf:1","agency","velocity","win:early","comp:brand"],"computed_at":"2026-10-24T06:02:35Z"},"pay":null,"html_url":"https://alion.io/job/hirevouch-backend-engineer-api","json_url":"https://alion.io/job/hirevouch-backend-engineer-api.json","meta":{"generated_at":"2026-10-25T04:25:37Z","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":5856,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-26T00:00:00Z"}},"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":4415880},"rest":"https://alion.io/mcp/rest/get_company?id=4415880"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fhirevouch-backend-engineer-api"},{"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%2Fhirevouch-backend-engineer-api"},{"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%2Fhirevouch-backend-engineer-api"},{"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/hirevouch-backend-engineer-api\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fhirevouch-backend-engineer-api"}]}
