Alongside partners with organizations to drive digital transformation and build high-performing tech teams.
We're looking for a mid-level engineer to own both backend service development and data engineering on a realtime facility navigation and asset-tracking platform for industrial and logistics sites. The platform ingests live positioning and telemetry data from BLE-based tracking hardware, correlates it into events (e.g., asset pickups, movement, dwell time), and exposes it through backend services to web and mobile clients.
What You'll Do
• Design, build, and maintain backend services and APIs (C#/.NET) that power the platform's core business logic.
• Implement and maintain the service layer for asset tracking, facility navigation, and event detection features.
• Integrate with third-party positioning/telemetry providers and their APIs.
• Define and evolve API contracts in collaboration with the frontend team (web admin portal and mobile app).
• Write automated tests, participate in code review, and help keep the codebase maintainable as the platform grows.
• Support deployment, monitoring, and troubleshooting of backend services in production.
Requirements
What We're Looking For
• 2–5 years of professional software engineering experience.
• Strong proficiency in C#/.NET for backend service development.
• Experience integrating with third-party APIs and webhooks.
• Comfortable working with real-time or near-real-time data processing requirements.
• Experience with a major cloud platform (Azure preferred, given the .NET stack).
• Strong communication skills and comfort working in a small, cross-functional, fast-moving team.
Nice to Have
• Experience with actor-model or distributed-systems frameworks (e.g., Orleans).
• Background in industrial, logistics, or IoT domains.
