Java Developer (Data Exchange Platform/DXP) Role

Role Overview

As a Java Developer on the DXP team, you'll contribute to backend systems handling sensitive data exchanges between government silos. Your code directly supports tactical operations, reducing latency in data delivery by up to 40% per project metrics. This internship accelerates your path from student to deploy-ready engineer.

Detailed Responsibilities

• Develop and optimize Java modules for secure data ingestion and transformation within the DXP.
• Implement RESTful APIs using Spring Boot to facilitate inter-agency data sharing.
• Collaborate on database schemas with PostgreSQL and Oracle for high-volume tactical datasets.
• Write unit and integration tests with JUnit and Mockito to ensure 99% code coverage.
• Troubleshoot production issues in Kubernetes-orchestrated environments.
• Document APIs and contribute to agile sprints via Jira tickets.
• Assist in security audits, applying OWASP standards to prevent data breaches.

Day-to-Day Workflow

Your day kicks off with a 9 AM standup on Microsoft Teams, reviewing sprint progress and blockers. Mornings involve coding new features in IntelliJ IDEA, paired with code reviews from senior devs. Afternoons shift to testing deployments on AWS GovCloud, followed by pull request discussions.

Expect 4-6 hours of focused development, interspersed with learning sessions on emerging standards like STANAG for NATO interoperability. End with retrospective notes, prepping for tomorrow's tasks—all remote, with flexible hours accommodating time zones.

Tools and Technologies

• Java 17+ with Spring Boot and Hibernate for core backend.
• PostgreSQL and Oracle DB for data persistence.
• Kubernetes and Docker for containerization on AWS GovCloud.
• Jira, Confluence, and GitHub for project management and version control.
• JUnit, Mockito, and SonarQube for testing and code quality.
• Postman and Swagger for API development and documentation.

Skills and Requirements

Technical Skills

Government Tactical Solutions seeks proficiency in Java programming, including multithreading and collections frameworks. Familiarity with Spring ecosystem—Boot, Data JPA, Security—is essential for DXP contributions. Knowledge of SQL, REST APIs, and cloud basics (AWS or Azure) sets strong candidates apart.

Bonus points for experience with message queues like Kafka or RabbitMQ, crucial for real-time data exchange. Security clearances aren't required upfront, but understanding FedRAMP or IL5 compliance helps.

Soft Skills

Strong problem-solving shines in debugging complex data flows under deadlines. Teamwork via clear PR comments and daily syncs is non-negotiable in remote settings. Curiosity drives interns to explore tactical use cases, asking questions that uncover edge scenarios.

Experience Expectations

Rising juniors or seniors in CS, software engineering, or related fields qualify—no grad degree needed. A GPA above 3.2 helps, but projects trump grades: showcase GitHub repos with Java apps handling data pipelines. Prior internships or hackathons involving APIs boost your profile; one relevant project can outweigh unrelated experience.

Salary and Benefits

For this remote internship in the upcoming season, expect $25–$35 per hour, aligning with DC-area defense tech rates—totaling $10,000–$14,000 for a 12-week stint. Full-time Java Developer roles post-internship start at $85,000–$110,000 base, plus bonuses.

Perks include a $1,000 learning stipend for Udemy or O'Reilly courses, full health coverage prorated, and 15 PTO days. Remote setup provides ergonomic reimbursements up to $500. High conversion rate—over 70% of interns transition to full-time offers.

Government Tactical Solutions Hiring Process

Step-by-Step Hiring Stages

1. Application: Submit resume and cover letter via Lever ATS, tailored to DXP keywords.
2. Screening: 15-minute recruiter call assessing fit and basic Java knowledge.
3. Assignment: 4-hour take-home coding challenge building a simple data exchanger.
4. Interviews: Two 45-minute rounds—technical deep-dive and behavioral with team leads.
5. Offer: Verbal next day, written within a week including background check initiation.

Application Timeline

Apply now for the upcoming season; postings drop in May, with rolling reviews through July. Process spans 3–5 weeks total, faster for standouts. Early apps (by mid-May) snag prime slots before summer crunch.

Screening Methods

Lever ATS scans for Java, Spring, DXP terms—mirror job description phrasing. Portfolios via GitHub links are reviewed; include live demos. Video intros via HireVue gauge communication for remote roles.

Interview Preparation

Example Interview Questions

• Design a REST API for secure data exchange between two government systems—what endpoints, auth, and error handling?
• Explain how you'd optimize a Java method processing 1M tactical records with memory constraints.
• Walk through implementing Spring Security for JWT-based authentication in DXP.
• Describe a project where you debugged a production data pipeline issue.

How to Answer

Use the STAR method: Situation, Task, Action, Result—for behavioral queries, quantify impacts like "reduced latency by 25%." For technicals, think aloud: diagram on Excalidraw, justify trade-offs. Practice with Pramp peers, timing responses to 3–5 minutes.

What Recruiters Evaluate

They prioritize clean, efficient code over perfection—focus on security and scalability. Cultural fit means mission alignment: express interest in defense tech ethics. Remote readiness shows via structured communication and self-motivation stories.

How to Get Selected

Practical Tips

• Tailor your resume with quantifiable Java projects: "Built Spring Boot app handling 10k req/min."
• Network on LinkedIn—connect with DXP engineers, reference mutual DoD interests.
• Complete the take-home early, adding tests and README for polish.
• Prepare DXP-specific questions: "How does DXP handle STANAG 4586 compliance?"

Common Mistakes to Avoid

• Generic resumes ignoring Government Tactical Solutions or DXP—ATS rejects 80%.
• Skipping security in coding tasks; breaches are instant disqualifiers.
• Poor remote etiquette: test setup, no distractions during calls.
• Overlooking soft skills—brag about team projects, not solo hacks.

How to Stand Out

Build a mini-DXP prototype on GitHub using public datasets, simulating tactical exchanges. Attend virtual DoD tech webinars, cite insights in interviews. Request informational chats with alumni via Handshake—personal referrals double odds. Submit a one-page "Why DXP" vision aligning your skills to their mission.
