As a Qualcomm Software Engineer, you will design, develop, create, modify, and validate embedded and cloud edge software, applications, and/or specialized utility programs that launch cutting-edge, world class products that meet and exceed customer needs. Qualcomm Software Engineers collaborate with systems, hardware, architecture, test engineers, and other teams to design system-level software solutions and obtain information on performance requirements and interfaces. Replacement PositionMinimum Qualifications:• Bachelor's degree in Engineering, Information Systems, Computer Science, or related field and 6+ years of Software Engineering or related work experience. OR Master's degree in Engineering, Information Systems, Computer Science, or related field and 5+ years of Software Engineering or related work experience. OR PhD in Engineering, Information Systems, Computer Science, or related field and 4+ years of Software Engineering or related work experience. • 3+ years of work experience with Programming Language such as C, C++, Java, Python, etc.We’re building the world’s most advanced SerDes PHY for use in AI data centers and beyond. The Embedded Software / Firmware Team at Qualcomm develops critical embedded software that powers high-performance multi-standard Serializer/Deserializer (SerDes) PHY IP used in next-generation data center, AI/ML, automotive, and compute applications. Our SerDes IPs support standards such as PCIe, Ethernet, CXL, and are integrated into SoCs, ASICs, and chiplets built by leading semiconductor companies around the world. The firmware team owns the full embedded software stack that controls the SerDes hardware, including low-level embedded firmware, customer-facing C SDKs, demo & automation scripts, and interactive tools. As a key enabler of silicon bring-up, validation, and production deployment, we work closely with hardware, systems, DV, validation, and application teams across the product lifecycle—from early development to high-volume manufacturing. We are looking for an experienced Firmware Engineer to lead firmware architecture, development, integration, and bring-up for our SerDes PHY portfolio. The ideal candidate has driven firmware definition, architecture, and development starting from the RTL/digital design phase with EDA tool/simulator integration, all the way through to the post-silicon phase with device-level bring-up and debug. This is a highly collaborative role: you will work with hardware, systems, and software teams to drive requirements and successful chip bring-up; with firmware and embedded software engineers to drive code re-use across the organization; and with program managers to identify and meet deadlines.
