The company’s culture is built around a customer‑first mindset, relentless innovation, and a commitment to delivering five‑nines reliability for next‑generation broadband services. The Associate SW Development Engineer role sits within the Broadband Devices Team, a high‑impact group responsible for shaping the future of multigigabit connectivity. As a fresher, you will work closely with senior engineers and hardware teams to design, develop, and debug embedded software that runs on network devices. You will gain exposure to real‑world networking stacks, cross‑layer troubleshooting, and the end‑to‑end product lifecycle from concept to field deployment. This is an excellent entry point for candidates passionate about low‑level programming, networking protocols, and building scalable software that powers the internet of tomorrow. Key responsibilities include: 1. Design and implement software features for embedded systems using C/C++. 2. Develop and maintain device drivers and protocol stacks for Layer‑2/3 networking. 3. Collaborate with hardware engineers to integrate firmware with silicon. 4. Perform root‑cause analysis of complex system issues reported by QA or customers. 5. Write automated test scripts (Python/Perl/Bash) to validate functionality and performance. 6. Participate in code reviews, ensuring adherence to coding standards and best practices. 7. Contribute to documentation, release notes, and technical specifications. 8. Support field troubleshooting and provide timely fixes for production issues. 9. Stay updated with emerging broadband technologies such as DOCSIS 4.0 and AI‑Ops. 10. Mentor junior interns and share knowledge within the team. The technical stack revolves around embedded Linux, real‑time operating systems, C/C++, networking protocols (Ethernet, IP, TCP/UDP, PPP, DOCSIS), and scripting languages for automation. Familiarity with version‑control (Git), build systems (Make/CMake) and debugging tools (gdb, JTAG) is advantageous. The role offers a clear growth path: starting as an Associate Engineer, you can progress to Software Development Engineer, Senior Engineer, and eventually lead a product line or specialize in network architecture and AI‑driven analytics. Harmonic’s emphasis on continuous learning, internal mobility, and exposure to global customers makes it an attractive place for ambitious engineers. Why join Harmonic? You will be part of a pioneering team that is redefining broadband connectivity for millions of users worldwide. The hybrid work model provides flexibility while ensuring regular face‑to‑face collaboration. Competitive compensation, performance‑linked bonuses, and a supportive learning environment make Harmonic a compelling choice for fresh graduates eager to make a tangible impact in the telecom domain.
