- Develop and integrate Linux-based applications and services for repeaters, dispatch consoles and network management, including IP networking, inter-site connectivity and remote configuration/OTA update features.
- Own New Product Introduction (NPI) and the move to manufacturing: DFM/DFT, Linux-based test automation and ATE development,



process documentation, and yield improvement.
- Manage product certification and compliance, including WPC/ETA, TEC, EMI/EMC, and environmental qualification to MIL-STD / JSS 55555 where applicable.
- Support indigenisation, BOM optimisation, component obsolescence management and vendor/EMS partner development.
- Act as technical interface with defence, government and enterprise customers, including support for tenders, technical evaluations and field trials.
- Build, mentor and lead a multidisciplinary team of RF, hardware, Linux/firmware and test engineers.
- Ensure quality systems compliance (ISO 9001 / AS9100) and support DGQA/STQC inspections as required.

Required Qualifications

- B.E./B.Tech or M.E./M.Tech in Electronics & Communication, Electronics & Telecommunication, Computer Science, or a related discipline.
- 10 to 25 years of experience in radio communication product development, with at least 5 years specifically on DMR, TETRA, P25 or tactical/software-defined radios.
- Robust hands-on experience with embedded Linux: kernel and driver development, Yocto/Buildroot, cross-compilation toolchains, shell scripting, and C/C++ programming.
- Working knowledge of Linux networking (TCP/IP, socket programming, VoIP/RTP) as applied to radio and repeater systems.
- Proven track record of taking at least one radio product from design to volume manufacturing.
- Strong working knowledge of RF test equipment, such as radio communication test sets, spectrum and network analysers, and signal generators.
- Experience leading teams and managing technical programs with defined timelines.

Preferred Background

- Exposure to SDR frameworks (such as GNU Radio) and processor platforms commonly used in radios, such as ARM Cortex-A/M, TI OMAP/Sitara, NXP i.MX or Xilinx Zynq.
- Familiarity with Linux security hardening, secure boot, and encryption implementation for defence-grade communication products.
- Familiarity with Indian defence procurement processes and certification bodies.
