Senior Signal Processing Engineer (PhD) – Advanced Sensing Systems Location: Pune Employment Type: Full-timeAbout the Role Altair is seeking a highly experienced Signal Processing Engineer with a Doctoral Degree to join our advanced sensing R&D initiatives. Our programs involve sophisticated, multi-sensor systems for object detection, classification, and high-accuracy positioning. The role requires deep expertise in both classical and modern signal processing techniques, with applications across underwater sensing and vision-based positioning systems. This is a senior, impact-heavy role suited for someone who has extensive hands-on experience building, optimizing, and deploying signal processing algorithms in real-world environments. Key Responsibilities Lead the development and refinement of algorithms for detection, recognition, and classification based on acoustic and optical sensor data. Apply advanced methods such as LOFAR , DEMON , STFT , and related spectral analysis techniques to real-world datasets. Architect robust pipelines for time–frequency analysis , noise reduction, feature extraction, and statistical modeling. Optimize algorithms for real-time or near–real-time performance on embedded and edge-compute platforms. Support parallel R&D efforts in vision-based positioning through signal-level operations such as threshold optimization, centroiding, denoising, and precision measurement . Mentor junior engineers and guide technical decisions across multidisciplinary teams. Lead field experiments, evaluate performance under varied environmental conditions, and drive improvements based on empirical results. Produce high-quality documentation, technical reports, and algorithm specifications. Required Skills & Qualifications PhD (Doctoral Degree) in Signal Processing, Acoustics, Applied Physics, Electrical Engineering, or a closely related field. 5–12+ years of hands-on experience in advanced signal processing R&D. Proven expertise in underwater-domain processing techniques including: LOFAR (Low Frequency Analysis & Recording) DEMON (Detection of Envelope Modulation On Noise) STFT (Short-Time Fourier Transform) Spectral estimation, beamforming, matched filtering, parametric modeling, etc. Strong proficiency in scientific programming (Python, MATLAB, C, C++, NumPy/SciPy). Extensive experience with noisy, low-SNR data and real-world sensor imperfections. Strong mathematical foundation in Fourier analysis, estimation theory, statistical signal processing, and detection theory. Demonstrated ability to take algorithms from concept → prototype → validated deployment-ready implementation. Excellent communication skills and ability to lead complex technical problem-solving. Preferred Qualifications Experience with underwater acoustics , passive/active sonar, or related sensing modalities. Background in image-domain signal processing , centroiding, threshold optimization, or feature localization. Experience working with multidisciplinary teams (optics, embedded, mechanical, AI/ML). Prior involvement in transitioning laboratory algorithms into robust field-ready systems. Who We're Looking For A seasoned expert who combines deep theoretical knowledge with strong practical engineering instincts. Someone comfortable leading algorithmic design, mentoring teams, and solving challenging problems across multiple sensing domains. A person who thrives in high-end R&D environments where rigor, innovation, and scientific clarity matter.
