Our work spans Agent Platform, ML Platform, Data Platform, and Ontology and Context Platform, alongside the Software Factory that accelerates enterprise software delivery.\n\nAs an FDE - Backend Engineer, you will work across platform development, enterprise integrations, re-architecture, and modernisation. You will use the Software Factory to deliver working software, identify gaps encountered during delivery, and turn those lessons into reusable improvements that help other engineers and teams move faster.\n\nThis is a backend engineering role across multiple products and enterprise projects. Your allocation may change based on priorities, delivery needs, and your strengths. You should be comfortable learning unfamiliar systems and owning work from understanding requirements through implementation, testing, deployment, and production support.\n\nResponsibilities: \nEnterprise Coding Platform / Software Factory: Backend services, integrations, and workflows that connect requirements, architecture, code generation, testing, code review, and deployment within enterprise SDLC processes.\nAgent Platform: Services for agent execution, tool integration, workflow orchestration, enterprise connectivity, and operational visibility.\nML Platform: Backend capabilities supporting model workflows, deployment, evaluation, and integration with enterprise applications.\nData Platform: APIs, connectors, ingestion and processing workflows, and services that make enterprise data accessible to applications and agents.\nOntology and Context Platform: Services for managing business concepts, relationships, metadata, and contextual knowledge, and exposing them to agents and applications.\nEnterprise modernisation: Understanding existing applications, redesigning service boundaries, re-engineering data access and APIs, replacing legacy integrations, and delivering changes across interconnected systems.\nBuild backend services: Design, implement, and maintain APIs, business logic, and shared services across platform products and enterprise applications.\nDeliver modernisation work: Understand existing codebases, trace dependencies and business behaviour, and implement re-architecture and modernisation changes while preserving required functionality.\nIntegrate enterprise systems: Connect internal applications, third-party platforms, and business systems through APIs, webhooks, messaging, and background jobs.\nBuild reusable components: Develop connectors, adapters, and shared libraries with authentication, data mapping, validation, and error handling.\nImplement reliable workflows: Handle timeouts, retries, idempotency, failure recovery, reconciliation, and asynchronous processing.\nApply the Software Factory: Use AI-assisted and agentic development workflows for codebase exploration, implementation, testing, debugging, and review, while remaining accountable for correctness and quality.\nImprove the Software Factory: Identify recurring delivery bottlenecks and contribute improvements to its backend services, integrations, templates, tools, context, and automated validation.\nAccelerate enterprise SDLC: Integrate Software Factory capabilities into existing repositories, issue tracking, review processes, test suites, and CI/CD pipelines.\nOwn delivery end to end: Take responsibility for assigned services and features from requirements and design through implementation, testing, deployment, monitoring, and issue resolution.\nValidate connected systems: Write automated tests, verify API contracts, and troubleshoot failures across services, data flows, and environments.\nCollaborate across teams: Work with product owners, architects, domain experts, and engineers to clarify requirements, resolve dependencies, and make practical engineering decisions.\nTurn project learning into platform improvements: Document useful patterns and convert repeated solutions into capabilities that can be reused across products and projects.\n\nRequirements: \nBackend programming: Strong skills in Python or TypeScript/JavaScript, 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.\nSoftware design: Good working understanding of object-oriented programming, abstraction, encapsulation, interfaces, and composition, with 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.\nAsynchronous workflows: Understanding of background jobs, messaging, retries, and reliable processing across service boundaries.\nSecurity: Understanding of authentication, authorisation, tokens, service credentials, and application permissions.\nExisting codebases: Ability to navigate unfamiliar applications, investigate dependencies, understand existing behaviour, and make reliable changes.\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.\nAI-assisted development: Willingness to use coding assistants and agents, critically review generated changes, and validate their behaviour through testing.\nOwnership and adaptability: Ability to work across products and project contexts, communicate clearly, investigate issues independently, and own outcomes through deployment.\n\nUseful experience — you do not need all of these: \nBackend frameworks and runtimes: FastAPI, Django, Node.js, or equivalents.\nEnterprise applications: CRM, ERP, identity providers, billing, order management, inventory systems, or other business platforms.\nModernisation and re-architecture: Legacy application analysis, service decomposition, API redesign, database migrations, integration replacement, or incremental migration.\nIntegration patterns: Webhooks, event-driven processing, scheduled synchronisation, batch integrations, and workflow orchestration.\nMessaging: Kafka, RabbitMQ, SQS, SNS, EventBridge, or equivalent technologies.\nData: PostgreSQL, MySQL, Redis, DynamoDB, query optimisation, and data processing pipelines.\nContext and ontology: Metadata services, knowledge graphs, semantic models, search, retrieval, or APIs that expose business context to applications and agents.\nAgent and ML platforms: Model APIs, MCP servers/clients, agent frameworks, model-serving APIs, evaluation workflows, or execution monitoring.\nAWS: ECS/Fargate, Lambda, API Gateway, S3, RDS, IAM, Secrets Manager, and CloudWatch. Relevant Azure or GCP experience is also welcome.\nContainers and orchestration: Docker and Kubernetes, including containerizing applications, configuration, and deployment troubleshooting.\nTesting: Robot Framework, Playwright, BDD scenarios written in Gherkin, and API, contract, integration, and end-to-end testing.\nGitLab and CI/CD: 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.\nDeveloper productivity: Building reusable templates, SDKs, CLI tools, development automation, or integrations that improve engineering workflows.\n\nWhat success looks like: \nYou deliver reliable backend capabilities across enterprise platforms and modernisation projects, take ownership through deployment, and use the Software Factory effectively to accelerate delivery.\nYour work also improves the factory itself, making recurring engineering tasks easier, faster, and more reliable for the next team and project.\nSkills\nAPI, DynamoDB, HTTP, JSON, JavaScript, MySQL, Node.js, PostgreSQL, Python, REST, Redis, SQL, TypeScript","description_format":"text","description_chars":8518,"description_truncated":false,"requirements":{"experience_years_min":1,"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":"2026-10-26T17:36:30Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":3,"expected_fill_days":21,"reasons":["seen:3","velocity","win:early","comp:junior"],"computed_at":"2026-10-30T05:48:23Z"},"pay":null,"html_url":"https://alion.io/job/physarum-backend-engineer-2","json_url":"https://alion.io/job/physarum-backend-engineer-2.json","meta":{"generated_at":"2026-10-30T19:35:36Z","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":9092,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-31T00:00:00Z"}},"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-2"},{"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-2"},{"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-2"},{"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-2\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fphysarum-backend-engineer-2"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3283999}},{"tool":"search_jobs","arguments":{"company":"physarum.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3283999},"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.
