Networking Knowledge: Experience configuring and troubleshooting Linux networking components, including interfaces, routing, DNS, DHCP, firewalls, and Wi-Fi. API and Application Development: Experience developing or debugging REST APIs, device-management applications, or web-based configuration interfaces. Version Control and Collaboration: Proficiency with Git and GitLab-based development workflows, including branching strategies, merge requests, and code reviews. CI/CD Experience: At least two years of experience building, maintaining, or troubleshooting automated continuous integration and continuous delivery pipelines. Testing Expertise: Experience developing unit, integration, system, or hardware-in-the-loop tests for software running on Linux-based systems or embedded devices. Communication Skills: Strong written and verbal communication skills, including the ability to produce clear, accurate, and maintainable technical documentation. Remote Collaboration: Ability to work independently and effectively with distributed, cross-functional engineering teams. Preferred Qualifications: Experience with NXP i.MX8 platforms, ARM64/AArch64 architectures, U-Boot, Linux kernel configuration, device trees, boot flows, or board-support packages. Experience migrating embedded Linux solutions to new hardware platforms or Linux distributions. Familiarity with OpenWrt build systems, package feeds, package Makefiles, and custom package development. Experience with AlmaLinux, Red Hat Enterprise Linux (RHEL), RPM/DNF, Kickstart, OSTree, SELinux, or RHEL Cockpit. Experience developing Python or Flask applications, OpenAPI/Swagger-documented APIs, or embedded device-management interfaces. Background in embedded networking products, routers, retransmission devices, cellular or modem integration, Wi-Fi, 802.1X, routing, or secure network configuration. Experience with device provisioning, firmware installation, software update mechanisms, and field-device maintenance. Knowledge of secure software development practices, certificate and PKI integration, vulnerability scanning, software bills of materials (SBOMs), CVE remediation, or tools such as Trivy.
