• Contribute directly to the development, sustainment, and modernization of a mission‑critical embedded retransmission device.
• Work across the embedded software lifecycle from Linux image creation and platform integration through networking services, device configuration, web‑based administration, testing, and release support.
• Collaborate with software, hardware, cybersecurity, test, systems engineering, and product teams.
• Help migrate an existing OpenWrt‑based device solution to next‑generation embedded hardware.
• Design, develop, integrate, test, debug, and maintain Linux‑based software for embedded networking and retransmission devices.
• Sustain and enhance the current OpenWrt‑based IRD firmware solution.
• Develop and maintain software in Python, Bash or shell scripting, C or C++, and other languages as needed.
• Execute development tickets supporting migration of existing IRD capabilities to next‑generation ARM‑based hardware.
• Assist with bootloader, kernel, board‑support, cross‑compilation, and embedded Linux image‑development activities.
• Develop and maintain Buildroot‑ and Linux‑based image creation, packaging, provisioning, release, update, and deployment workflows.
• Contribute to the evolution of a Linux or RHEL‑based management architecture.
• Develop and maintain REST APIs and device‑management user‑interface capabilities.
• Implement, maintain, and troubleshoot networking capabilities.
• Create and maintain unit, integration, system, simulation, and hardware‑connected test capabilities.
• Participate in GitLab merge‑request reviews, CI or CD pipeline maintenance, build validation, and release engineering.
• Support secure software development activities.
• Create and maintain design, build, API, test, and operational documentation.
• Collaborate with hardware engineers, systems engineers, cybersecurity personnel, quality assurance, and product management.

Qualifications

• Bachelor’s degree in Computer Science, Computer Engineering, Electrical Engineering, or a related technical discipline.
• Five or more years of relevant professional software‑development experience.
• At least five years of experience developing, integrating, testing, or sustaining software for Linux‑based systems.
• Experience developing software using Python, Bash or shell scripting, and C or C++.
• Experience working with Linux system configuration, debugging, networking, package management, and software deployment.
• Experience developing, integrating, and debugging software for ARM‑ and/or Intel or x86‑based devices.
• Experience with embedded Linux build systems or distributions such as OpenWrt, Buildroot, Yocto, or equivalent technologies.
• Experience with cross‑compilation, embedded Linux image creation, software packaging, and deployment to embedded targets.
• Experience with Linux networking, including network‑interface configuration, routing, DNS, DHCP, firewalling, Wi‑Fi, and troubleshooting.
• Experience developing and debugging REST APIs, device‑management applications, or web‑based configuration interfaces.
• Experience with Git and GitLab‑based development practices.
• At least two years of experience building, maintaining, or troubleshooting automated CI or CD pipelines.
• Experience creating unit, integration, system, or hardware‑in‑the‑loop tests for software deployed to Linux‑based systems.
• Strong written and verbal communication skills.
• Ability to work effectively in a remote, cross‑functional development environment.

Requirements

• Experience with NXP i.MX8, ARM64 or AArch64, U‑Boot, Linux kernel configuration, device trees, boot flows, or board‑support packages.
• Experience porting an embedded Linux solution to a new hardware platform or Linux distribution.
• Experience with OpenWrt buildroots, feeds, package Makefiles, and custom OpenWrt package development.
• Experience with Alma Linux, RHEL, RPM or DNF, Kickstart, OSTree, SELinux, or RHEL Cockpit.
• Experience developing Python or Flask applications, OpenAPI or Swagger‑documented APIs, or embedded device‑management UIs.
• Experience with embedded networking products, retransmission devices, routers, cellular or modem integration, Wi‑Fi, 802.1X, routing, or secure network configuration.
• Experience with device provisioning, firmware or image installation, update mechanisms, or field‑device sustainment.
• Experience with secure software‑development practices, certificate or PKI integration, vulnerability scanning, SBOMs, CVE remediation, or tools such as Trivy.
• Experience with containerized builds, simulated device environments, or hardware‑in‑the‑loop testing.
• Experience supporting DoD, mission, tactical‑edge, disconnected, or regulated embedded‑device environments.

Benefits

• A culture of integrity.
• An environment of trust with flexible time off benefits.
• A focus on continuous growth and opportunities for career advancement.
• Comprehensive benefits including healthcare, wellness, financial, retirement, family support, continuing education, and time off benefits.
