Senior Mobile Developer (iOS / Android) - TS Cleared

Location: Washington, D.C. (Onsite) Clearance Required: Active Top Secret Position Status: Direct Hire Salary: Up to $216,000

Position Overview

We are seeking an experienced Senior Mobile Developer to design, build, and deploy secure, high-performance mobile applications supporting a mission-critical federal program in Washington, D.C. This is a hands-on engineering role for a developer who has personally owned the full mobile development lifecycle - from architecture and coding through testing, deployment, and sustainment. You will work alongside a collaborative team of engineers to deliver native and cross-platform applications that operate reliably in secure, high-stakes environments.

If you take pride in clean code, thoughtful architecture, and shipping products that make a real impact, this role offers the autonomy, technical challenge, and long-term stability of a direct-hire position.

What You'll Do

  • Design, develop, and maintain native and/or cross-platform mobile applications for iOS and Android in a secure environment.
  • Own features end to end - architecture, implementation, testing, deployment, and ongoing optimization.
  • Collaborate with product owners, UX designers, and backend engineers to translate requirements into intuitive, performant mobile experiences.
  • Write clean, well-documented, maintainable code and participate in peer code reviews.
  • Integrate mobile applications with secure RESTful APIs, backend services, and authentication frameworks.
  • Optimize application performance, security, and responsiveness across devices and OS versions.
  • Apply secure coding practices and support accreditation, compliance, and DevSecOps requirements.

Required Skills & Experience

  • Active Top Secret clearance (required to start).
  • 7+ years of professional software development experience, with a strong concentration in mobile development.
  • Demonstrated, hands-on expertise building native mobile applications using Swift / SwiftUI / Objective-C (iOS) and/or Kotlin / Java (Android).
  • Proficiency integrating mobile apps with RESTful APIs, microservices, and secure authentication (OAuth, SSO, PKI).
  • Solid command of mobile architecture patterns (MVVM, MVC), version control (Git), and CI/CD pipelines.
  • Experience with the full mobile development lifecycle, including testing frameworks, debugging, and App Store / enterprise deployment.
  • Strong problem-solving skills and the ability to work independently in an onsite, collaborative team setting.
  • Bachelor's degree in Computer Science, Software Engineering, or a related field (equivalent professional experience considered).

Preferred Qualifications

  • Experience with cross-platform frameworks (React Native, Flutter).
  • Background developing for secure, federal, or DoD/IC environments.
  • Familiarity with mobile device management (MDM), containerization, or secure mobile frameworks.
  • Knowledge of cloud platforms (AWS, Azure) and DevSecOps practices.
