This position is responsible for all phases of embedded software development, including requirements analysis, architecture, design, coding, integration, test, debugging, release readiness, and maintenance for device drivers, communications protocols, secure firmware update mechanisms, and other embedded software applications. The successful candidate has sufficient experience and expertise to address medium to complex assignments, structure and manage technical approaches, and make inventive design recommendations that meet performance, security, schedule, and cost targets. This role leads technical support staff in testing and analysis, contributes ideas and concepts that demonstrate self-motivation and sound engineering judgment, and is adept at analyzing complex technical issues, identifying root causes, and proposing effective solutions. Responsibilities * Design and develop organized, maintainable, easy-to-review software source code for embedded systems from requirements through production, including development effort estimates. * Debug software/firmware using emulators, analyzers, simulators, and similar tools. * Develop applications using industry-standard technologies, defined APIs, specified SDKs, and applicable Apple MFi specifications. * Create object libraries, applications, daemons, and drivers deployed inside embedded hardware devices. * Document software designs, code, interfaces, verification plans, and end-user documentation. * Develop embedded applications in C or C++ with working knowledge of assembly. * Develop applications and drivers for operating systems such as Zephyr, FreeRTOS, and derivatives from IC manufacturers. * Develop board support packages for new hardware platforms. * Demonstrate working knowledge of cross-functional and related technical areas such as software quality techniques, software configuration management, and release management. * Write clear and concise technical specifications, design documents, test outlines, procedures, and code review artifacts. * Use AI-assisted development tools responsibly for code generation, debugging, refactoring, documentation, test development, and code review; validate outputs against requirements, architecture, coding standards, and confidentiality obligations. * Design firmware security controls, including secure boot, signed images, encrypted/authenticated communications, secure key handling, secure OTA update flows, rollback prevention, and vulnerability mitigation. * Apply secure coding practices, threat modeling, static analysis, dependency review, and peer review throughout the development lifecycle. * Research upcoming projects, firmware technologies, AI-enabled engineering practices, and product security requirements; present findings to corporate leadership and integrate results into team technical strategy. * Work closely with electrical, mechanical, quality, and software engineers, industrial designers, product managers, vendors, and manufacturing to ensure successful project coordination and integration. * Foster a culture of collaboration and knowledge-sharing. * Monitor and meet project schedules and cost objectives. * Ability to work independently/self-manage and collaborate with cross-functional teams for system integration. * Work closely with outsource engineering and other resources across time zones and represent Belkin interests on-site as part of an engineering team. * Participate in and/or lead peer-to-peer and cross-functional design review meetings. * Perform all other duties as assigned and required.
