Job Description
About Us:
Wanco is an innovative leader in fleet management solutions, providing cutting-edge technology to optimize transportation operations, ensure compliance with regulatory standards, and enhance real-time data integration for safer and more efficient roadways. Our platform supports a wide range of clients in the transportation sector, leveraging cloud-based architectures to deliver scalable, reliable services. About the Role We're looking for a back-end developer with solid full-stack instincts to join a small, cross-functional team building Fleet Manager — a real-time fleet and device management platform deployed in containerized microservices environments. The work is predominantly back-end (APIs, messaging, integrations), but you'll also touch a modern React frontend as the team migrates away from a legacy AngularJS app. React exposure is a plus but not expected — we'll bring you up to speed on the frontend migration. What You'll Work On- Building and maintaining RESTful APIs in Ruby on Rails
- Writing Node.js / Express microservices that handle device telemetry, push notifications, and inter-service communication
- Working with NATS (publish/subscribe message broker) for event-driven service coordination
- Managing and querying MariaDB (MySQL-compatible) relational databases
- Authoring and maintaining Dockerfiles and Docker Compose configurations for a microservices environment
- Contributing to React / TypeScript frontend work as we modernize the UI layer
- Debugging across service boundaries — logs, WebSockets, UDP streams, and REST Required Skills
- 3+ years back-end development experience
- Proficiency in Ruby on Rails or a comparable MVC web framework (willing to ramp on Rails)
- Node.js for microservice development
- Relational databases (PostgreSQL, MySQL/MariaDB — schema design, query optimization)
- Docker and Docker Compose for containerized local development and deployment
- CI/CD pipeline experience (GitHub Actions or similar)
- Comfort reading and writing REST APIs
- Familiarity with event-driven and pub/sub patterns Nice to Have
- TypeScript for type-safe Node.js services
- AWS infrastructure experience (Fargate, S3, RDS) and Infrastructure-as-Code (Terraform)
- Experience with NATS or similar message brokers (RabbitMQ, Kafka, Redis Pub/Sub)
- React and React Query for frontend data-fetching patterns
- Observability tooling (Datadog or similar log aggregation and alerting platforms)
- Exposure to device/IoT protocols (NTCIP, CalAmp, SunTech, or similar)
- Go experience (used for CLI tooling)
- Any work with S3-compatible storage (Min
IO, AWS S3
) You'll Thrive Here If You- Can trace a bug across multiple services with nothing but logs and a Docker network
- Prefer working in a small team where your contributions ship quickly
- Are comfortable with a mixed-age codebase — there's legacy code here alongside greenfield work
- Don't need heavy process; we value working software over comprehensive documentation
