Position Overview

We are looking for a motivated and capable Full
Stack Software Engineer to work across our product: the Java / Spring Boot services and REST APIs, the PostgreSQL databases behind them, and the React / TypeScript web applications our customers use.

You will join the CTO Engineering group, working closely with the backend, data, and product teams. The platform runs as one codebase across many customer deployments, so a large part of the work is making changes that behave correctly everywhere. You will take features end to end, from the database and the API to the screen.

Key Responsibilities

• Develop and maintain backend services in Java / Spring Boot and the REST APIs that expose our data
  
• Build and maintain web application features in React / Next.js and TypeScript
  
• Design database schemas and indexes, and keep queries fast as data grows
  
• Work on the services that receive and decode measurements from devices in the field
  
• Build monitoring and alerting, and investigate production incidents
  
• Work on our AWS infrastructure
  
• Actively participate in design and code reviews
  
• Deliver high-performance, reliable, reusable code that solves business problems efficiently and is easy to understand and maintain
  
• Identify and implement improvements for the modules you own
  
• Support and enhance CI/CD practices
  
• Contribute to improving team processes and ways of working
  
• Share knowledge and collaborate closely with colleagues

• Working knowledge of Python, or readiness to pick it up — parts of our platform are written in it
  
• Experience working in Linux environments
  
• Experience with automated testing (unit + e2e) and CI/CD pipelines
  
• Knowledge of modern software engineering practices across the full software development lifecycle (SDLC) — coding standards, code reviews, source control management, build processes, testing, CI pipelines
  
• Strong problem solving and troubleshooting abilities
