Note: The job is a remote job and is open to candidates in USA. PRhobe, Inc. is rebuilding the economics of logistics tracking through its RIoT device, which captures item-level location and condition data and reports it to the cloud. The Software Engineer UI, Cloud & Backend Design Lead will own the backend cloud platform, digital twin data model, alerting engine, customer-facing UI, and partner integrations for production logistics applications.
Responsibilities
- Backend cloud platform. Build and operate ingestion, device management and processing on a managed IoT cloud, then lead the evaluation and, if warranted, migration to a (hybrid) PRhobe-owned platform. Pragmatism first, then durability
- Digital twin data model. Maintain per-item state for serial-numbered goods associated to a RIoT at each blink — location, custody, environmental history — across journeys crossing carriers, borders and months
- Bandwidth economics. Cellular payload is a direct cost and a direct battery cost. Design the delta representation of tag populations with the Firmware Engineer so we send changes, not inventories
- Alerting and value propositions. Build the rules and analytics behind real-time inventory count and accuracy, ETA deviation, route change, partial load separation, shrinkage and spoilage risk, theft last-known-location, hazardous proximity and multi-factor delivery authentication
- Customer-facing UI. A clear interface for inventory count, location, environmental state (temperature, humidity, air quality), device health and journey history — supporting real customer pilots at production grade
- Traceability and partner integrations. Model events so one structure serves DSCSA serialization in pharma, FSMA 204 tracking events in food, item-level inventory in retail and PPAP-grade evidence in automotive. Build the APIs, ASN/EDI exchanges and audit trails that make RIoT useful to our customers and to the logistics software they already run
Skills
- AI fluency — mandatory. You use Claude, ChatGPT, Perplexity, Grok or equivalent daily and have multiplied your own throughput, on the order of 10x or more rather than a marginal gain. Be ready to walk us through what you delegate, what you deliberately do not, and how you verify
- 5+ years building and operating production backend systems, including services you personally kept running
- Data engineering instincts for high-volume time-series and event data, and schemas that survive years of change. PostgeSQL, MQTT/COAP
- Event-driven or streaming architecture; an alerting engine that is both accurate and cheap to run, supporting observability, logging and metrics
- Practical API design and third-party integration, including documentation partners can actually build against. REST, Websockets etc
- Sufficient front-end capability to own an operational dashboard end to end supporting security, authentication, authorization, multi-tenancy
- Time-series and event data at fleet scale, with cost-aware query, retention and rollup, and with event queues
- Working knowledge of multi-tenant security and data isolation — our customers compete with one another
- BSCS or equivalent practical background
- Managed IoT platform experience (AWS IoT, Azure IoT, Google Cloud IoT or similar) — provisioning, fleet management, telemetry
- Logistics, WMS or track-and-trace domain experience in automotive, pharma, retail or food
- GS1 EPCIS, SGTIN and EPC Gen2 identifiers; DSCSA or FSMA 204 data models; Flutter or an equivalent front-end framework
Benefits
- 401(k) with 6% employer match
- 90% employer-paid medical, dental and vision
- Remote and hybrid arrangements within California open to discussion
- Generous equity
- Your name goes on the patents you earn
