Job Type: Full-time
About Us:
7 Darter Info Services Pvt Ltd is an innovative SME driving cutting-edge wireless solutions for India’s defence sector.

We’re 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:
We’re seeking a skilled Physical Layer/Baseband Processing Engineer to design and implement waveforms for our wireless communication system (Basic and Advanced versions).

You’ll 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 (
- 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.
