Scottsdale, PHX - onsite 4 days per week


Our client is a large-scale, nationally recognised residential real estate business, managing thousands of single-family rental homes across the US. With strong year-on-year growth and a people-first culture — recognised as a certified Great Place to Work® for two consecutive years — they're building out a high-performing engineering team to support an increasingly digital-first operation. This is a business at genuine scale, with the complexity and technical ambition to match.


The Role

As a Senior Backend Engineer, you'll be a core part of a dynamic, agile engineering team responsible for designing and delivering high-performance, cloud-native applications on AWS. You'll work closely with architects and senior developers, contributing to both technical strategy and hands-on delivery — with roughly an 80/20 backend/frontend split.


Speed to market matters here. You'll be working in a fast-paced environment where quality and velocity go hand in hand.


What You'll Be Doing

  • Designing and building scalable, cloud-native microservices using AWS Serverless, Kubernetes, Docker, Node.js, and TypeScript
  • Working with MongoDB and key-value stores for performant data solutions
  • Contributing to technical design of cloud and digital platforms alongside architects and senior engineers
  • Evaluating emerging technologies and developing proof-of-concept solutions
  • Refactoring and re-architecting existing software where needed
  • Building reusable components and driving consolidation across projects
  • Supporting testing, UAT, deployment, and post-release activities
  • Managing bugs, features, and issues through JIRA
  • Producing and reviewing solution blueprints and architecture documentation


What They're Looking For

  • 6–8 years of solid backend development experience building internet-scale web/mobile applications and public APIs
  • Strong expertise in Node.js, TypeScript, AWS Serverless, and MongoDB
  • Proven experience building microservices and REST APIs with a focus on system design
  • Solid understanding of public cloud (AWS preferred) and both SQL and NoSQL
  • Experience across the full SDLC — Agile, iterative development, CI/CD tooling (Jenkins, GitHub/BitBucket, Docker, containers)
  • Strong communicator — comfortable engaging with both technical teams and business stakeholders
  • Exposure to React, React Native, GraphQL, or Salesforce is a plus
  • Bachelor's degree in Computer Science, IT, or a related engineering discipline
