  • Strong experience in server-side multi-threaded programming in Java, HTTPS, and web services.
  • Design and development experience with relational databases, preferably PostgreSQL, and JPA or Hibernate.
  • Ability to analyze and remediate cybersecurity vulnerabilities within applications, including proficiency with network protocols and security measures such as mTLS authentication and encryption techniques.
  • Experience in authoring technical documentation and collaborating effectively in Agile and Scrum environments.
  • BS degree in Computer Science, Software Engineering, or equivalent practical experience (education and credentials as applicable).

Desired Skills & Experience
