You should be comfortable building APIs, connecting systems, handling data and asynchronous workflows, and taking changes through testing and deployment. We welcome different technology backgrounds and value engineering fundamentals, ownership, and learning ability.\nResponsibilities:\nDesign, build, and maintain backend services, APIs, and business logic.\nIntegrate internal applications, third-party platforms, and enterprise systems through APIs, webhooks, messaging, and background jobs.\nBuild reusable connectors and adapters with authentication, data mapping, validation, and error handling.\nImplement reliable workflows with timeouts, retries, idempotency, failure recovery, and reconciliation.\nWork with databases, caching, application permissions, and asynchronous processing.\nUnderstand existing codebases, trace dependencies, and make reliable changes across services.\nWrite automated tests, verify API contracts, and troubleshoot failures across connected systems.\nContribute to containerization, CI/CD pipelines, AWS deployments, and production monitoring.\nUse AI-assisted development tools to accelerate delivery while remaining accountable for correctness and quality.\nRequirements:\nExperience: Typically 3-10 years; strong candidates outside this range are welcome.\nBackend programming: Strong skills in at least one language, such as Python, Java, TypeScript/JavaScript, or Go, with hands-on experience developing backend services and REST APIs.\nIntegration engineering: Experience connecting applications or systems, including authentication, request/response mapping, validation, and handling integration failures.\nObject-oriented programming: Good working understanding of abstraction, encapsulation, interfaces, and composition, and the ability to structure modular, maintainable code.\nAPI fundamentals: Understanding of HTTP, JSON, API contracts, status codes, pagination, and versioning.\nDatabases: Practical experience with SQL, relational databases, schema design, and transactions.\nSecurity: Understanding of authentication, authorization, tokens, service credentials, and application permissions.\nEngineering practices: Experience with Git, code reviews, automated testing, and systematic debugging, along with exposure to CI/CD and application deployment.\nAgentic AI and MCP familiarity: Basic understanding of agents, tool calling, and Model Context Protocol, including how agents interact with APIs and backend systems. Exposure through professional work, personal projects, or experimentation is welcome.\nOwnership and judgment: Ability to navigate unfamiliar codebases, investigate issues across service boundaries, communicate clearly, and make timely decisions.\nUseful experience: you do not need all of these:\nBackend frameworks and runtimes: FastAPI, Django, Node.js, or equivalents.\nEnterprise integrations: CRM, ERP, identity providers, billing, order management, inventory systems, or other business platforms.\nIntegration patterns: Webhooks, event-driven processing, scheduled synchronization, batch integrations, and workflow orchestration.\nMessaging: Kafka, RabbitMQ, SQS, SNS, EventBridge, or equivalent technologies.\nData: PostgreSQL, MySQL, Redis, DynamoDB, query optimization, and database migrations.\nAWS: ECS/Fargate, Lambda, API Gateway, S3, RDS, IAM, Secrets Manager, and CloudWatch. Relevant Azure or GCP experience is also welcome.\nContainers and orchestration: Working understanding of Docker and Kubernetes, including containerizing applications, configuration, and deployment troubleshooting.\nTesting tools and practices: Familiarity with Robot Framework, Playwright and BDD scenarios written in Gherkin. Experience with API, integration, and end-to-end testing across connected services.\nGitLab and CI/CD: Familiarity with GitLab repositories, merge requests, and pipelines for automated builds, tests, and deployments. Experience with GitHub Actions, Jenkins, or similar tools is also relevant.\nInfrastructure as code: Basic understanding of Terraform, including reading and modifying existing configurations and reviewing infrastructure plans.\nSecurity and reliability: OAuth2/OIDC, JWT validation, RBAC, least-privilege access, audit logging, monitoring, tracing, and production troubleshooting.\nAI integrations: Model APIs, MCP servers/clients, agent frameworks, and workflows.\nAI-assisted/agentic coding: Familiarity with coding assistants or coding agents for implementation, testing, debugging, or exploring codebases is helpful, but not mandatory Candidates should be willing to learn these tools and critically review and validate generated code.","description_format":"text","description_chars":4741,"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":["Machine Learning","Low-Code & No-Code Platforms"],"lifecycle":[{"event":"open","at":"2026-10-14T02:14:19Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":0,"expected_fill_days":19,"reasons":["seen:0","win:early"],"computed_at":"2026-10-14T06:34:16Z"},"pay":null,"html_url":"https://alion.io/job/physarum-backend-engineer","json_url":"https://alion.io/job/physarum-backend-engineer.json","meta":{"generated_at":"2026-10-14T11:43:20Z","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":14020,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-15T00:00:00Z"}},"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":2349},"rest":"https://alion.io/mcp/rest/get_company?id=2349"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fphysarum-backend-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%2Fphysarum-backend-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%2Fphysarum-backend-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/physarum-backend-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fphysarum-backend-engineer"}]}
