Back-End Software Developer (Full-Stack Lean

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

Do you have experience in TypeScript?, · 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 (MinIO, 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
