• Develop and maintain signal processing algorithms and associated hardware implementations for PNT positioning products
• Collaborates with internal and external customers and technical peers to solve complex system problems
• Support system design by identifying and recommending design and requirements needs for future enhancements
• Contribute to all aspects of the product life cycle (concept, development, integration, qualification, acceptance, delivery, and maintenance)
• Follows established configuration/change control processes

What You’ll Need to Succeed:

• Bachelor’s degree in Engineering, Computer Science, Aerospace Engineering, Physics, Applied Mathematics, or related field
• 5+ years of experience with digital radio systems such as GPS/GNSS or software definable radios
• Knowledge of GPS/GNSS technology and navigation algorithm
• Experience with simulation and debugging with MATLAB/Octave
• Ability to work seamlessly within a team as well as manage individual tasks
• Proven ability to work independently, designing, developing, and deploying solutions, and delivering projects on time with minimal direction
• Ability to listen and evaluate all opinions without bias, and contribute to a common culture of excellence
• Possess an analytical mindset, with the ability to understand a situation or problem and think critically to make decisions or come up with solutions
• Be active in seeking out ways to continuously improve yourself and gain new knowledge

Things That Would be Nice if You Brought to the Table:

• Familiarity with digital processing techniques including: FIR/IIR/adaptive filtering, modulation, demodulation, convolution, cross-correlation, spectral methods (Fourier, wavelet), phase-locked loops, numerically controlled oscillators, etc.
  
• Experience with hardware/software partitioning of digital signal processing functions to optimize throughput and/or SWAP
  
• Knowledge of analog systems and components utilized in the transmission and reception of RF waveforms such as filters, antennas, amplifiers, modulators, mixers, and ADC/DAC.
  
• Familiarity with digital communication topics such as channel models, carrier/symbol synchronization, block codes, convolutional codes, equalization, etc.
  
• Experience in the simulation and analysis of radio systems, algorithms, and data processing chains
  
• Proficient in linear algebra, probability, and stochastic processes
  
• Experience with linear and/or non-linear optimization using standard techniques such as least squares, weighted least squares, and Kalman Filtering
  
• Understanding of numerical considerations/tradeoffs between fixed point and floating point arithmetic when implementing signal processing algorithms
  

Things That Would be GREAT if You Brought to the Table:

• Master’s or PhD in Engineering, Computer Science, Aerospace Engineering, Physics, Applied Mathematics, or related field
• Knowledge of space mission design/analysis and orbital mechanics
• Experience working on the design of GPS/GNSS receivers
• Familiarity with embedded software development environment and tools for real-time embedded operating systems (RTOS), such as VxWorks and FreeRTOS
• Knowledgeable in programming concepts including data structures, algorithms, databases, and multithreading
• Solid understanding of memory management on embedded platforms
• Familiarity with common RF/HW/FW/SW tools such as oscilloscope, logic analyzer, signal generator, spectrum analyzer, network analyzer, Chipscope, GDB, JTAG, etc.
• Experience with RF/hardware design and debugging
• Ability to read and understand schematic drawings and component datasheets
• Experience in FPGA development (VHDL, Verilog), and associated synthesis + place/route tools

We’ll also need you to:

• Be a US Citizen (due to government contracts)
