Controls Engineer, Amazon Leo Optical Inter-Satellite Link

Amazon Leo is Amazon's low Earth orbit satellite network. Our mission is to deliver fast, reliable broadband connectivity to customers beyond the reach of existing networks. From households to small businesses, schools, hospitals, and government agencies, Amazon Leo will serve communities and organizations operating in places without dependable internet access.

We are looking for a PAT Engineer to assist in the development, testing, and validation of pointing, acquisition, and tracking (PAT) systems for free-space optical links across the Amazon LEO satellite constellation. This role blends electrical engineering, opto-mechatronics, and controls knowledge to support the PAT team across FPGA verification, hardware integration and testing, and model-based design. You will work closely with senior PAT engineers to execute test campaigns, maintain verification infrastructure, and help bridge the gap between algorithm models and hardware implementations.

This is an on-site role. The position sits within the OISL Electrical Engineering team, with workload focused on PAT/controls activities directed by the senior PAT engineer and also supporting the EE team on production RCAs, trade studies, and board-level design and bring-up. The split is flexible based on program phase and candidate strengths. Day to day, you will work alongside senior PAT engineers and EE team members, contributing across multiple work streams.

A controls-focused background is ideal, with supporting knowledge in electrical engineering, mechanical systems, optics, or aerospace. The role requires comfort moving between flight data analysis, simulation, test infrastructure, and hardware debug depending on program needs. Flexible hours may be needed during test campaigns, and occasional travel to integration/testing facilities is required. Over time, there is opportunity to grow ownership of specific PAT subsystems and take on more independent technical leadership within the PAT and EE domains.

• 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

Due to applicable export control laws and regulations, candidates must be a U.S. citizen or national, U.S. permanent resident (i.e., current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum.

• Bachelor's degree in electrical engineering or equivalent
• 3+ years 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 with reading schematics and understanding digital/analog signal interfaces
• Experience with control system fundamentals — feedback loops, transfer functions, stability concepts
• Experience with working across disciplines — comfortable interfacing with EE, FPGA, and mechanical teams
• Experience analyzing test or flight data to identify trends, anomalies, and correlations

• Data converter (ADC/DAC) electrical characteristics, architectures, and design tradeoffs (SNR, ENOB, linearity, settling time), including basic understanding of sampling theory, decimation/interpolation filters, and anti-aliasing as they relate to converter performance in closed-loop control systems
• Analog and mixed-signal board-level design and troubleshooting best practices (power integrity,…
