Job Title: Jr. Java Engineer (Product / Integration)
Location: Dania Beach, FL (South Florida residents only)
Type: Contract-to-Hire (6-month conversion)
Work Model: Primarily remote with 2 on-site days per month. Initial 3–6 weeks require 4–5 days per week on-site for onboarding and training.

Summary: We’re looking for three Junior Java Engineers to join a high-energy Product & Integration Engineering team. This group builds custom travel-related applications and integrations in a fast-paced environment. You’ll start with maintenance work to learn the ecosystem and quickly progress to new development projects.

Responsibilities:

• Write and maintain Java code (approximately 90% hands-on development).
• Build and support synchronous REST services (and some asynchronous services).
• Develop integration patterns between multiple systems and ensure reliable, scalable connections.
• Implement unit tests, maintain test coverage, and perform performance testing on REST services.
• Collaborate with senior engineers and the manager to learn architecture, design principles, and best practices.

Required Skills & Experience:

• 3–5 years of professional Java development experience (able to read and write clean, simple Java code: variables, loops, methods, classes, packages).
• Experience developing synchronous integration patterns/services and some asynchronous services.
  • Synchronous = one system calls another and waits for a response (like a phone call).
  • Asynchronous = send a message/request and process later (like a text).
• Understanding of:
  • Integration Patterns – common ways systems talk to each other.
  • Service Architecture – how services are designed and why.
  • Service API Security – securing APIs against unauthorized access.
  • Building REST Services – designing, building, and securing REST APIs in Java.
• 2+ years of hands-on unit testing experience:
  • Ability to understand requirements and write unit tests verifying services/functions meet requirements.
  • Maintain strong test coverage across the codebase.
• At least 1 year of cloud experience (GCP preferred, AWS or Azure also acceptable).
• 2+ years working in an enterprise environment (1,000+ employees).
• Stable work history (no more than two employers if ~3 years’ experience, no more than three if ~5 years).

Nice to Have:

• Real-time API experience.
• Prior experience building REST services from the ground up.

Who Thrives Here

• Self-motivated engineers who deliver quickly and independently.
• Curious learners eager to grow under senior engineer mentorship.
• Comfortable starting with maintenance work before shifting to new feature development.
• Excited to come on-site initially to meet the team and learn the systems.
