Engineer - RF SW

Qualcomm interviews typically start with a timed online coding test focusing on data structures, algorithms, and C language fundamentals. The technical round dives deep into RF concepts, modem driver design, and real‑time debugging scenarios, often accompanied by whiteboard problem solving. The final HR round assesses cultural fit, communication skills, and motivation. Candidates are advised to practice hands‑on coding, review RF fundamentals, and be ready to discuss recent projects.

Qualcomm promotes a high‑performance yet inclusive culture where engineers are encouraged to experiment, fail fast, and iterate. The company provides structured mentorship, regular tech talks, and a balanced work‑life environment with flexible timings and remote‑work options where applicable.

Bachelor's or Master's degree in Electronics & Communication Engineering, Electrical Engineering, Computer Engineering or related discipline; minimum 60% aggregate (or CGPA 6.5/10); final year students of 2024, 2025 or 2026 batches; no active backlogs at the time of joining; strong foundation in C/C++ programming, digital communications and RF theory.

Round 1: Online aptitude & coding test → Round 2: Technical interview (core C/C++ and RF concepts) → Round 3: HR interview (fitment and behavioral).

Qualcomm India Private Limited is a global leader in wireless technology, renowned for pioneering 3G, 4G LTE, and 5G solutions that power billions of devices worldwide. With a strong focus on research, development, and innovation, Qualcomm creates end‑to‑end platforms that enable smartphones, IoT devices, automotive systems, and cloud‑edge services to communicate seamlessly. The company’s culture blends cutting‑edge engineering with a collaborative, inclusive environment that encourages continuous learning and rapid career growth. The role of Engineer – RF SW – ECE is positioned within Qualcomm’s Modem‑RF Software team in Hyderabad. As a fresh graduate or early‑career engineer, you will contribute to the design, development, and validation of software drivers and algorithms that control Qualcomm’s modem‑RF transceivers. You will work closely with hardware, RF ASIC, and baseband teams to translate system‑level requirements into high‑performance, low‑latency software that powers LTE and 5G NR communications. **Key Responsibilities** 1. Develop, debug, and maintain C/C++ drivers for Qualcomm Modem‑RF transceivers on embedded RTOS platforms. 2. Implement and optimize RF front‑end algorithms, antenna tuning, and link‑budget calculations to improve system performance and yield. 3. Collaborate with RF hardware engineers to integrate and validate new silicon features and test‑mode functionalities. 4. Participate in cross‑functional design reviews, providing software feasibility feedback and performance estimates. 5. Create automated test scripts and validation suites using protocol test equipment, spectrum analyzers, and oscilloscopes. 6. Diagnose complex RF‑modem issues reported by field teams and propose software‑level fixes. 7. Contribute to documentation, code reviews, and knowledge‑transfer sessions within the team. 8. Stay updated with emerging wireless standards (LTE‑Advanced, 5G NR) and incorporate relevant enhancements into the software stack. 9. Support product ramp‑up activities, including silicon bring‑up, factory testing, and post‑silicon validation. 10. Mentor interns and junior peers, fostering a culture of technical excellence. **Tech Stack**: C, C++, Embedded C on RTOS (e.g., FreeRTOS), Linux kernel basics, RF simulation tools, Python for scripting, version control (Git), and familiarity with LTE/5G protocol stacks. **Growth Path**: Successful engineers can progress to Senior RF Software Engineer, Lead Engineer, or System Architecture roles, with opportunities to work on next‑generation 6G research, cloud‑edge integration, or product management. **Why Join Qualcomm?** The company offers exposure to world‑class wireless technologies, mentorship from industry veterans, and a clear, merit‑based career ladder. Employees benefit from competitive compensation, generous learning budgets, and a vibrant campus that celebrates diversity and innovation.
