Backend Engineer (Remote: Vietnam)

Location: Vietnam

Department: Alongside

Workplace: remote

Employment Type: part

Description

Alongside partners with organizations to drive digital transformation and build high-performing tech teams.
Were 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 Youll Do

• Design, build, and maintain backend services and APIs (C#/.NET) that power the platforms 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 Were 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.

Benefits

• Remote work (Vietnam-based)
• Estimated project duration: 19 weeks
• Full-time schedule: 4 hours per day overlapping with Portugal business hours
• Freelance / Service Agreement
• Hourly Rate: 12$-16$
