## Description

**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.

-   **Estimated project duration:** 19 weeks
-   **Part-time schedule:** 4 hours per day overlapping with Portugal business hours
