Job description

SOFTWARE DEVELOPER - AUTOMATION TEAM
Department: QA Automation Engineering
Location: Remote (within 70 miles of Allen, TX preferred)
Role Type: Contract-to-Hire (6 months) | W2
ABOUT OUR CLIENT
We're partnering with a well-established financial technology company that powers the banking and financial services industry. Founded in 1976, they serve 9,000+ clients with 7,000+ employees and generate $2.39 billion in annual revenue. They're known for their collaborative culture, commitment to engineering excellence, and investment in cutting-edge technology-including AI tooling, cloud modernization, and homegrown platforms built to scale. Their company philosophy: Do the right thing, do whatever it takes, and have fun.
JOB DESCRIPTION
Join a small, collaborative QA Automation Team and take ownership of a custom in-house testing platform that powers how the QA team automates and executes test cases. You'll work on a true development role-writing code 100% of the time across a full-stack environment. This team of five operates under a supervisor who prioritizes mentorship and growth, so if you're a junior or mid-level developer, you'll have direct guidance from senior leadership while building real impact.
You'll be designing, developing, and supporting a custom web application that's mission-critical to the company's QA operations. You'll enhance existing software to boost stability and usability, collaborate with the QA team to refine testing scenarios, and partner with development teams to drive resolution of issues discovered during testing. This is an opportunity to build something tangible and be part of a purpose-driven engineering culture.
WHAT YOU'LL BE RESPONSIBLE FOR
  • Design, develop, test, and support a custom internal web application used by the QA team
  • Enhance existing software to improve stability, usability, accessibility, and feature set
  • Collaborate with the QA Test Team to develop test scenarios and generate simulated transactional data
  • Interact with Subject Matter Experts (SMEs) and development teams to refine the QA automation environment
  • Partner with development teams to track and drive resolution of issues discovered during QA testing
  • Contribute to the development of test objectives and performance-related requirements
  • Assist with training and documentation related to software enhancements and platform updates
  • Stay current on software development best practices and communicate relevant trends to the team

WHAT YOU'LL NEED TO HAVE
  • 18+ months of experience developing REST APIs
  • Proficiency in JavaScript, TypeScript, and Angular (or comparable front-end framework)
  • Solid understanding of Object-Oriented Programming principles (inheritance, abstraction, interfaces)
  • Experience with a modern source code repository (Git, GitHub, or Azure DevOps)
  • Strong written and verbal communication skills
  • Ability to work in a requirements-driven, Agile delivery environment

NICE-TO-HAVES
  • Bachelor's degree in Computer Science or a related field
  • Experience with C# and .NET development
  • SQL Server experience, including minor administration
  • Familiarity with document databases such as MongoDB
  • Experience with CI/CD pipelines
  • Google Cloud Platform (GCP) experience-a cloud migration is underway and GCP knowledge is a plus
  • Basic Unix/Linux skills including shell scripting
  • Java familiarity (exposure to Java applications is helpful but not required)
  • Exposure to AI coding tools such as GitHub Copilot or Gemini-based platforms
  • Knowledge of the software development lifecycle and QA processes
  • Windows Server administration (minor)

PAY & BENEFITS SUMMARY
  • $60-$65/hr. W2
  • Contract-to-Hire: 6 months with a conversion target salary of $136,350/year
