Verification. Evidence.\nWhy This Role Exists\nEvery scan, photo, and workflow event on a customer's floor lands in our backend. The volume is real: thousands of devices sending scans and images all day, often from spots with bad connectivity, dropping offline and syncing back later. Enterprise customers notice every slow query and every lost event.\nWe're hiring a Senior Backend Engineer (Full Stack) to build and scale the services, APIs, and integrations that carry that load, along with the web screens customers and internal teams use to configure and run the platform. You'll work with product, mobile, AI, and implementation teams to turn messy physical operations into software that holds up in production.\nThe role is backend-first. You'll design data models, build services and APIs, run integrations with customer ERPs, WMSs, and TMSs, and keep the platform fast and dependable as customers scale. You'll also ship across the stack: the dashboards, configuration tools, and admin screens that sit on top of your own APIs. You'll take a feature from schema to screen without waiting on a separate frontend team, make architecture calls, own your services in production, and get pulled into customer integrations when they get hard.\nHow This Role Works\nThis is one role with two modes, and you'll move between them often, sometimes in the same week.\nBackend mode. You're in the services: designing data models and APIs, building workflow and event-processing logic, integrating with customer systems and our Vision AI pipeline, and owning what you ship in production.\nFull stack mode. You're in the web app: building the dashboards, workflow configuration tools, and reporting views that customers and our implementation teams use every day, on top of the APIs you designed.\nBoth halves matter. If you're a backend engineer who won't touch a UI, or a frontend engineer who has never owned a production service and a database, this probably isn't your role. If you genuinely enjoy both, keep reading.\nWhat You'll Do\nDesign and build the backend services and APIs that power the PackageX platform, mobile app, and web console.\nModel data for complex, configurable workflows (events, evidence, and customer configuration) and keep it consistent as volume grows.\nBuild and maintain integrations with customer ERPs, WMSs, TMSs, third-party APIs, webhooks, and data exports.\nWrite event-driven and async processing with queues, workers, and scheduled jobs.\nBuild the backend behind Vision AI features, image ingestion, processing pipelines, and result storage, and work with the AI team to move results from model to platform to customer report.\nHandle offline sync and conflict resolution for data coming in from mobile devices on the floor.\nBuild web features end to end, from API to UI: dashboards, configuration tools, admin, and reporting. Our web stack uses both React and Svelte.\nFind and fix slow queries, bottlenecks, and reliability issues before customers feel them.\nOwn your services in production: deploys, monitoring, logging, alerting, on-call, and post-incident fixes.\nKeep the platform secure: access control and multi-tenant data isolation.\nWrite tests, review code, and keep design docs and API documentation in a state other engineers can build on.\nJoin implementation and customer conversations when an integration or data issue needs an engineer in the room, and push for reusable platform patterns over one-off customer builds.\nYou Might Be a Fit If\nBackend engineering\nYou've spent 5+ years building and running production backend services.\nYou're strong in Node.js/TypeScript, Python, or Go.\nYou know relational databases well: schema design, indexing, query tuning, and migrations. We run both MySQL and PostgreSQL.\nYou've designed APIs and built integrations with third-party or enterprise systems.\nYou've worked with queues and async processing (SQS, RabbitMQ, Kafka, or similar).\nYou've deployed and run services on AWS or GCP, with Docker and CI/CD pipelines.\nFull stack\nYou have hands-on React experience and can ship a production-ready web feature on your own. This is required.\nYou've worked with Svelte, or you're confident picking it up quickly. Parts of our web stack use it, so prior experience is a real plus.\nYou're comfortable owning a feature from database schema to UI.\nHow you work\nYou communicate clearly with technical and non-technical teammates.\nYou're comfortable owning ambiguous problems and making sound calls without a perfect spec.\nYou stay close enough to customer workflows to understand why what you're building matters.\nNice to have\nNone of these are required, but any of them will make us sit up:\nYou've integrated with ERP, WMS, TMS, or other logistics and enterprise systems.\nYou've worked on image pipelines, ML-backed products, or mobile backends with offline sync.\nYou've built or run multi-tenant SaaS platforms.\nYou've worked in logistics, supply chain, manufacturing, warehousing, or another operations-heavy space.","description_format":"text","description_chars":5480,"description_truncated":false,"requirements":{"experience_years_min":5,"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":["Supply Chain & Logistics Software"],"lifecycle":[{"event":"open","at":"2026-10-15T10:41:52Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":0,"expected_fill_days":30,"reasons":["conf:0","velocity","win:early"],"computed_at":"2026-10-16T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/packagex-senior-backend-engineer-full-stack","json_url":"https://alion.io/job/packagex-senior-backend-engineer-full-stack.json","meta":{"generated_at":"2026-10-16T09:19:33Z","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":7439,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-17T00:00:00Z"}},"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":180056},"rest":"https://alion.io/mcp/rest/get_company?id=180056"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fpackagex-senior-backend-engineer-full-stack"},{"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%2Fpackagex-senior-backend-engineer-full-stack"},{"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%2Fpackagex-senior-backend-engineer-full-stack"},{"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/packagex-senior-backend-engineer-full-stack\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fpackagex-senior-backend-engineer-full-stack"}]}
