Job Title: Physical Layer/Baseband Processing Engineer

Company: 7 Darter Info Services Pvt Ltd

Location: Hyderabad

Job Type: Full-time

About Us:

7 Darter Info Services Pvt Ltd is an innovative SME driving cutting-edge wireless solutions for Indias defence sector. Were developing a next-gen wireless systems, featuring advanced RF and DSP technologies to deliver secure, anti-jamming surveillance. Join us to shape the future of defence tech under Make in India!

Job Description:

Were seeking a skilled Physical Layer/Baseband Processing Engineer to design and implement waveforms for our wireless communication system (Basic and Advanced versions). Youll develop FHSS and FHSS-OFDM waveforms, implement them on DSPs, and collaborate with our RF team to deliver a rugged. This is a hands-on role in a lean, high-impact team.

Responsibilities:

• Design and develop FHSS waveforms (500 hops/s, QPSK) for the Basic version, targeting half-duplex operation at 2 Mbps.
• Create FHSS-OFDM waveforms (64 subcarriers) for the Advanced version, enabling full-duplex transmission over 5 MHz bandwidth.
• Port waveforms from MATLAB simulations to DSPs (e.g., C55x for Basic, C6748 for Advanced)20-50 MFLOPS optimisation.
• Implementing the designed waveform on TI DSPs.
• Ensure waveform synchronisation (<1 s jitter) and anti-jamming performance (13 dB gain vs. 20 dB J/S).
• Collaborate with the RF Engineer to integrate waveforms with RF hardware (HackRF, AD9361).

Qualifications:

• B.Tech/M.Tech in ECE, Electrical Engineering, or related field from a reputed institute .
• 7+ years of experience in physical layer design and baseband processing for wireless systems.
• Proficiency in waveform development (FHSS, OFDM, QPSK)MATLAB and C required.
• Hands-on experience with TI DSPs (e.g., C55x, C6748)TI Code Composer Studio expertise.
• Knowledge of RF systems (350-450 MHz) and defence-grade anti-jamming techniques.
• Familiarity with WPC/DoT regulations is a plus.
• Strong problem-solving skills and ability to work in a lean, fast-paced team.
