You will develop commercial product features inside a high-performing Scrum team — Java, Spring Boot, REST APIs, event-driven systems, and microservices. This is a mid-to-senior hands-on engineering seat, not an internship or junior coding role.

  • Work in microservices and distributed architecture.

  • Design and work with modern databases.
  • Write correct code for single- and multi-threaded environments.
  • Participate in Scrum delivery, design discussions, and planning.
  • Apply modern security principles in application development.
  • Deliver production-quality features and take/give feedback within the team.

Required Qualifications:
  • 5+ years of commercial Java software development (internships do not count).
  • Strong hands-on Java, Spring, and Spring Boot.
  • Proven experience with REST APIs and event-driven systems.
  • Experience with microservices and distributed architecture.
  • Commercial use of build, test, and dependency-management tools.
  • Modern database design and technologies.
  • Understanding of single- vs multi-threaded application requirements.
  • Experience delivering product functionality on a Scrum team.
  • Bachelor's degree in Computer Science.
  • Strong analytical, design, and problem-solving skills.
  • Ability to work on-site in Irving, TX.
  • Must be legally authorized to work in the United States without sponsorship now or in the future.

Preferred Qualifications:
  • Mining, industrial, or other complex enterprise product software.
  • Modern application-security practices and technologies.
