Digital Signal Processing Engineer

Job Description

We are seeking a skilled and analytical DSP Engineer to join our team in transforming raw sensor data into actionable insights. Our proprietary drill bit sensors collect high-frequency vibration and motion data during drilling operations. Your mission will be to analyze these signals, identify patterns that predict drill bit failure, and help us understand the root causes behind those failures.

This is a hands‑on role where you’ll work closely with cross‑functional teams to develop algorithms that interpret complex waveforms and improve operational efficiency in high‑noise environments.

• Analyze vibration and motion signals from downhole sensors to detect anomalies and predict drill bit failure.
• Develop and implement time–frequency analysis techniques including:
  • Fourier Transform
  • Short‑Time Fourier Transform (STFT)
  • Wavelet Transforms
• Design and apply advanced filtering methods:
  • FIR/IIR filters
  • Adaptive filters
  • Band‑pass filters for vibration/noise separation
• Extract meaningful features from raw signals:
  • RMS, spectral energy, dominant frequency, entropy
  • Statistical moments, Hilbert transforms
• Perform sensor fusion using data from accelerometers, gyroscopes, and magnetometers:
  • Kalman filters
  • Complementary filters
  • Custom sensor fusion algorithms
• Build models for noise reduction and anomaly detection in high‑noise drilling environments.
• Collaborate with hardware, software, and data science teams to validate signal interpretations and improve system performance.
• This role requires an onsite presence 5 days / week in Downtown Houston, with flexible working hours.

• Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, or a related field.
• Strong experience in DSP algorithm development and signal analysis.
• Proficiency in MATLAB, Python, or C/C++ for signal processing.
• Familiarity with embedded systems and real‑time data acquisition.
• Experience working with sensor data in noisy environments is highly desirable.
• Excellent problem‑solving and communication skills.

We are a company committed to creating diverse and inclusive environments where people can bring their full, authentic selves to work every day. We are an equal opportunity/affirmative action employer that believes everyone matters. Qualified candidates will receive consideration for employment regardless of their race, color, ethnicity, religion, sex (including pregnancy), sexual orientation, gender identity and expression, marital status, national origin, ancestry, genetic factors, age, disability, protected veteran status, military or uniformed service member status, or any other status or characteristic protected by applicable laws, regulations, and ordinances.
