About the Role
As a Senior Signal Processing Engineer, you will develop advanced signal processing and noise subtraction algorithms for a state-of-the-art magnetic navigation system. Working closely with the data, AI/ML, and navigation teams, you will design algorithms to remove noise and artifacts from sensor data streams. You will also create digital twins to generate realistic noise models, enabling the training of new algorithms. Continuously refining models with new sensor data and algorithm enhancements, you will ensure their accuracy for ongoing testing. Additionally, you will analyze results, identify optimization opportunities, and collaborate with cross-functional teams to enhance system performance and reliability, driving advancements in aircraft navigation and sensor integration.
What You’ll Do
- Develop and implement advanced algorithms for signal denoising, noise reduction, and feature extraction from time series data
- Collaborate with multidisciplinary teams to apply signal processing techniques to real-world sensor data problems
- Conduct experiments and simulations to evaluate and optimize the performance of denoising algorithms
- Explore and integrate machine learning methods to enhance signal processing techniques and achieve better noise reduction
- Collaborate with multidisciplinary teams to integrate learnings into broader system architectures
- Contribute to the development of technical documentation, including specifications, design documents, and test plans
About You
- Bachelor’s Degree in a relevant field with 5+ years software development in a rapidly scaling startup or research setting
- Strong foundation in signal processing concepts, including Fourier analysis, filtering, modulation, and spectral estimation
- Strong foundation in Python, with experience in numerical/scientific Python (e.g. NumPy, SciPy, etc)
- Hand-on experience with time-series data analysis and sensor data processing
- Experience with machine learning techniques for signal processing applications
- Problem-solving skills and ability to work independently or collaboratively
- Ability to thrive in ambiguous situations
- U.S. Citizenship is required due to USG contract requirements
Nice to Haves
