About the role

PAT Engineer role focused on pointing, acquisition, and tracking (PAT) systems for free-space optical links in the Amazon LEO satellite constellation. Combines electrical engineering, opto-mechatronics, and controls to support FPGA verification, hardware integration and testing, and model-based design across flight data analysis, simulations, and board-level debugging.

Responsibilities

  • Flight Data Analysis & Simulation Correlation
  • • Analyze flight telemetry data and compare against simulation predictions — identify discrepancies, characterize on-orbit behavior, and support anomaly investigations
  • • Run and maintain simulation environments to reproduce flight scenarios and validate model fidelity against observed data
  • • Help narrow down root causes by correlating flight data trends with known model behaviors and hardware characteristics
  • Production Failure Support & RCA
  • • Support production and on-orbit failure investigations — review data, identify patterns, and help narrow down failure modes
  • • Assist with electrical RCAs and help debug board-level issues
  • • Contribute to failure analysis reports and corrective action documentation
  • • Support production ramp activities requiring EE analysis and hardware troubleshooting
  • FPGA Verification & Test Vector Development
  • • Develop and maintain test vectors to verify PAT FPGA implementations against Simulink reference models
  • • Run bit-accurate simulations, compare outputs, and flag discrepancies between model and FPGA behavior
  • • Work with existing models of PAT control loops and state machines — run simulations, generate test cases, and validate behavior
  • • Support model-in-the-loop (MIL), software-in-the-loop (SIL), and hardware-in-the-loop (HIL) verification activities
  • Electrical Engineering Support
  • • Contribute to trade studies for data converter selection and signal chain architecture
  • • Support board-level testing, characterization, and troubleshooting for analog and mixed-signal circuits
  • • Assist with electrical design reviews
  • • Support production ramps and RCAs from an electrical and controls perspective
  • Documentation & Configuration Management
  • • Document test procedures, results, RCA findings, and discrepancy investigations clearly
  • • Help maintain version-controlled models, scripts, and test artifacts
  • • Contribute to test reports, review materials, and configuration management records

Qualifications

  • BS degree in electrical engineering or equivalent
  • Professional experience in a hardware-adjacent controls, test, or systems engineering role
  • MATLAB/Simulink proficiency — comfortable running models, interpreting results, building test cases, and debugging issues
  • Experience analyzing test or flight data to identify trends, anomalies, and correlations
  • Experience with reading schematics and understanding digital/analog signal interfaces
  • Experience with lab instrumentation (oscilloscopes, logic analyzers, signal generators, spectrum analyzers)
  • Experience with control system fundamentals — feedback loops, transfer functions, stability concepts
  • Experience with fixed-point concepts — word length, fraction length, overflow, quantization error
  • Experience with version control (Git)
  • Experience with working across disciplines — comfortable interfacing with EE, FPGA, and mechanical teams
