[Hiring] Embedded Linux Engineer @CACI International

Role Description

In this position, you will be an Embedded Linux Software Developer supporting the current IRD embedded retransmission device and its next‑generation replacement platform. The current IRD solution is a customized OpenWrt‑based embedded Linux device that provides networking and retransmission capabilities. It includes:

• Firmware image integration
• Custom OpenWrt packages and feeds
• Networking and security services
• Device configuration
• Administrative user interface

The next‑generation effort is migrating the solution to new embedded hardware while evolving the platform toward a Linux‑based solution. This is an individual‑contributor role. You will primarily execute assigned development, integration, sustainment, and defect‑resolution work while collaborating with senior engineers and cross‑functional teammates on:

• Technical direction
• Platform architecture
• Hardware integration
• Cybersecurity
• Release planning

Responsibilities include:

• Be part of an awesome team working with cutting‑edge embedded Linux, networking, and device‑management technologies.
• 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 to release support.
• Collaborate with various teams to deliver secure, reliable, and maintainable capabilities.
• Migrate an existing OpenWrt‑based device solution to next‑generation embedded hardware.
• Design, develop, integrate, test, debug, and maintain Linux‑based software.
• Sustain and enhance the current OpenWrt‑based IRD firmware solution.
• Develop and maintain software in Python, Bash, C, or C++.
• Execute development tickets for migration of existing IRD capabilities.
• Assist with bootloader, kernel, and embedded Linux image‑development activities.
• Develop and maintain Buildroot‑ and Linux‑based image creation 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 testing capabilities.
• Participate in GitLab merge‑request reviews and CI/CD pipeline maintenance.
• Support secure software development activities.
• Create and maintain design, build, API, test, and operational documentation.
• Collaborate with various engineering teams to implement and validate product requirements.

To be successful in this position, you will enjoy solving moderately to highly complex problems that cross embedded Linux, networking, device configuration, platform integration, testing, and security domains.

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, and firewalling.
• Experience developing and debugging REST APIs 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.
• 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

• Healthcare
• Wellness
