About the Position

Senior Backend Engineer, .NET & Python

Global Fleet Management is seeking a Senior Backend Engineer to join our team in Burnaby, British Columbia. We are a company that builds a real-time GPS fleet tracking SaaS platform, processing millions of GPS data points daily across multiple receiver protocols.

This is a full-time, on-site position at our Burnaby, BC headquarters. It is not available for remote or hybrid work.

Responsibilities

• Build and maintain backend services in .NET 8 / C# and Python (FastAPI, Dramatiq workers, Dask data pipelines)
• Design microservice boundaries, API contracts, and data flows as we decompose a monolithic Rails application into independent services
• Work directly on core platform systems: GPS telemetry ingestion, history processing, reporting engine, dispatching services, billing and subscription management
• Write and review production-grade, test-driven code; enforce quality through code reviews across.NET and Python codebases
• Design and optimize MySQL queries and schemas for high-volume transactional workloads (10M+ row tables, complex joins across billing/device/contract hierarchies)
• Build and consume RESTful APIs; design webhook delivery systems and event-driven integrations
• Deploy to production via BitBucket Pipelines, Docker, and Kubernetes (GKE) with zero-downtime rolling updates
• Produce architecture documentation: system diagrams, data flow diagrams, ADRs in Confluence
• Manage async job processing with RabbitMQ and Dramatiq/Delayed Job workers
• Operate within Google Cloud Platform: GKE, Cloud SQL, Cloud Storage, Secret Manager, BigQuery
• Collaborate with the Rails team, DevOps, and QA; work with the Engineering Team Lead and VP of Engineering on technical direction
• Estimate tasks, communicate blockers, and participate in sprint planning using Jira and GitFlow branching

Requirements

• Production experience with.NET 8 / C# -- building, testing, and deploying backend services
• Production experience with Python -- FastAPI or Flask, async task processing, data manipulation (Pandas, Dask)
• Strong MySQL skills: query optimization, indexing strategies, schema design for high-load systems
• Experience with at least one of: PostgreSQL, Elasticsearch, MongoDB, BigQuery
• Hands-on Docker + Kubernetes (GKE preferred): writing Dockerfiles, managing deployments, debugging pod issues, reading container logs
• Experience with RabbitMQ or similar message brokers and async job queues
• Track record of designing and implementing microservices -- service decomposition, inter-service communication, API versioning, backward compatibility
• Familiarity with Redis for caching and session management
• Experience with Git/GitFlow branching workflow and BitBucket or similar platforms
• Ability to write clear technical documentation and communicate tradeoffs to both engineers and non-technical stakeholders
• Strong written and spoken English

Nice to Have

• Experience with Ruby on Rails; understanding Rails conventions and ActiveRecord is critical for designing migration paths
• Experience with Go
• MongoDB experience
• Experience with Elixir
• Background in IoT / telematics: GPS device protocols, high-throughput telemetry ingestion, real-time data pipelines
• Experience with AI/ML integration: MCP servers, LLM API orchestration
• WebSocket experience for real-time data delivery
• Experience with Angular frontend; helpful for full-stack debugging
• SOC2 compliance experience
• Monitoring and observability: Zabbix, GrayLog, GCP Cloud Monitoring
• API documentation practices (Swagger/OpenAPI)

We Offer

• On-site, full-time at our Burnaby headquarters -- no remote, no hybrid
• Salary: CA$110,000 -- CA$145,000/year based on experience
• Direct architectural impact on a multi-service SaaS platform processing real-time GPS data at scale
• State-of-the-art hardware, JetBrains licenses (Rider, PyCharm, RubyMine)
• Paid vacation, holidays, and sick days
• Benefits program
• Architect-track career progression
• Work across the full stack: .NET microservices, Python data pipelines, Rails, GKE infrastructure
