About The Position
We are seeking an experienced Senior Software Development Engineer to join our team at Ericsson and help develop the next generation of WiFi networking hardware. In this role, you will lead the development of low-level software powering WiFi access points, routers, and wireless network infrastructure devices, ensuring industry-leading reliability, performance, and security. You'll serve as a technical leader, collaborating closely with hardware, software, and QA teams to architect features, drive WiFi feature implementation, and define best practices for wireless embedded development. If you're passionate about embedded development and excited to solve real-world challenges in connectivity, scalability, and network efficiency, this is your opportunity to make a direct impact in a dynamic, high-tech environment.
Requirements
- At least 5 years’ experience with a strong foundation in programming, predominantly Python and/or C
- At least 5 years’ working knowledge of Linux operating systems, including basic shell scripting and system-level concepts
- Understanding of computer networking fundamentals (e.g., IP/TCP/UDP, Ethernet, routing and switching)
- Exposure to embedded platforms such as ARM-based SoCs, microcontrollers, or development boards
- Track record of technical leadership: mentoring engineers, driving architecture decisions, and owning complex features end-to-end
- Strong debugging skills across the full stack — from RF and PHY up through the OS and application layer
- Eagerness to learn new technologies and grow within a fast-paced, collaborative engineering environment
Nice To Haves
- General networking knowledge to WiFi-specific technologies (802.11ax/be)
