Job description
As a Sr. Mobile Developer (Cross-Platform) , you’ll design, build, and sustain secure iOS and Android applications with the goal of delivering mission-critical mobile capabilities across the federal government. Our engineering team is responsible for building and operating high-security mobile solutions for a highly visible government customer, and you’ll play a key role in delivering reliable, secure, and scalable applications by contributing immediately within an Agile delivery model, collaborating closely with security and backend teams, and driving disciplined execution in a classified environment.
We know that you can’t have great technology services without amazing people. At MetroStar, we are obsessed with our people and have led a two-decade legacy of building the best and brightest teams. Because we know our future relies on our deep understanding and relentless focus on our people, we live by our mission: A passion for our people. Value for our customers.
What you’ll do:
Design, develop, test, integrate, optimize, and debug secure web applications and backend services in Java, Python, JavaScript/TypeScript, or similar languages, including UIs built with HTML, CSS, and modern web frameworks.
Develop backend services and application logic integrating REST APIs, SQL databases, and enterprise systems, using PostgreSQL, Microsoft SQL Server, or comparable platforms.
Develop, refactor, and maintain automation scripts (PowerShell, Python, Bash, or similar) and work in Linux environments to support troubleshooting, command-line diagnostics, scripting, and deployment tasks.
Build dashboards, monitoring views, telemetry applications, and operational tools that improve visibility for support teams and mission stakeholders, including simplified interfaces, automated workflows, and guardrails enabling Tier 1/operational personnel to handle repeatable tasks with less engineering escalation.
Apply secure coding practices across web, backend, database, scripting, API, mobile, and integration work, and troubleshoot complex application, integration, automation, data, Linux, and API issues in a secure enterprise environment.
Document code, architecture, API integrations, database dependencies, SOPs, and support procedures for post-delivery maintainability.
Support mobile and UC-adjacent deliverables as needed, including cross-platform mobile apps, Android/enterprise Android integrations, Cisco UC tooling, VPN diagnostics, SIP/RTP visibility, and packet-loss/network-degradation testing utilities.
Coordinate with application development, UC, mobile, endpoint, network, cybersecurity, database, Tier 1 support, and Government stakeholders to ensure solutions are usable, supportable, secure, and operationally aligned.
What you’ll need to succeed:
Active Top Secret security clearance with SCI eligibility.
Bachelor's degree in Computer Science or a related field preferred; relevant experience may substitute.
5+ years of full stack software development experience.
Experience developing web applications and backend services.
Experience with Java, Python, JavaScript/TypeScript, or similar languages.
Experience with HTML, CSS, and modern web frameworks.
Experience with PowerShell, Python, Bash, or similar scripting languages.
Experience with REST APIs and SQL databases, preferably PostgreSQL or Microsoft SQL Server.
Experience developing in Linux environments.
Strong troubleshooting, automation, and secure coding skills.
Ability to work in secure, mission-critical DoD or federal environments with strong documentation and operational discipline.
