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.\nThis 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.\nDay to day, you will work alongside senior PAT engineers and EE team members, contributing across multiple workstreams. 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.\nOver time, there is opportunity to grow ownership of specific PAT subsystems and take on more independent technical leadership within the PAT and EE domains.\nKey job responsibilities\nFlight Data Analysis & Simulation Correlation\nAnalyze flight telemetry data and compare against simulation predictions - identify discrepancies, characterize on-orbit behavior, and support anomaly investigations\nRun and maintain simulation environments to reproduce flight scenarios and validate model fidelity against observed data\nHelp narrow down root causes by correlating flight data trends with known model behaviors and hardware characteristics Production Failure Support & RCA\nSupport production and on-orbit failure investigations - review data, identify patterns, and help narrow down failure modes\nAssist with electrical RCAs and help debug board-level issues \nContribute to failure analysis reports and corrective action documentation\nSupport production ramp activities requiring EE analysis and hardware troubleshooting FPGA Verification & Test Vector Development\nDevelop and maintain test vectors to verify PAT FPGA implementations against Simulink reference models\nRun bit-accurate simulations, compare outputs, and flag discrepancies between model and FPGA behavior\nWork with existing models of PAT control loops and state machines - run simulations, generate test cases, and validate behavior\nSupport model-in-the-loop (MIL), software-in-the-loop (SIL), and hardware-in-the-loop (HIL) verification activities Electrical Engineering Support\nContribute to trade studies for data converter selection and signal chain architecture\nSupport board-level testing, characterization, and troubleshooting for analog and mixed-signal circuits\nAssist with electrical design reviews\nSupport production ramps and RCAs from an electrical and controls perspective Documentation & Configuration Management\nDocument test procedures, results, RCA findings, and discrepancy investigations clearly\nHelp maintain version-controlled models, scripts, and test artifacts\nContribute to test reports, review materials, and configuration management records Export Control Requirement: 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.\nBasic qualifications\n- BS degree in electrical engineering or equivalent\n- Professional experience in a hardware-adjacent controls, test, or systems engineering role\n- MATLAB/Simulink proficiency - comfortable running models, interpreting results, building test cases, and debugging issues\n- Experience analyzing test or flight data to identify trends, anomalies, and correlations\n- Experience with reading schematics and understanding digital/analog signal interfaces\n- Experience with lab instrumentation (oscilloscopes, logic analyzers, signal generators, spectrum analyzers)\n- Experience with control system fundamentals - feedback loops, transfer functions, stability concepts\n- Experience with fixed-point concepts - word length, fraction length, overflow, quantization error\n- Experience with version control (Git)\n- Experience with working across disciplines - comfortable interfacing with EE, FPGA, and mechanical teams\nPreferred qualifications\n- 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\n- Analog and mixed-signal board-level design and troubleshooting best practices (power integrity, signal integrity, grounding)\n- Experience with production hardware debug and root cause analysis\n- Preferred Qualifications - Additional\n- Low-noise design techniques (grounding, shielding, power supply filtering)\n- Filter design basics (active/passive, analog/digital)\n- Digital interface protocols (SPI, I2C, LVDS, CAN, Ethernet) and use cases\n- Basic programming experience (Python, C, or scripting for test automation)\n- Awareness of radiation effects (SEU, TID) on semiconductor devices\n- Thermal considerations for space-qualified electronics\n- Experience in aerospace or defense environments\n- Tools & Technologies\n- MATLAB/Simulink, Python, Git, lab instrumentation (oscilloscopes, logic analyzers, signal generators, spectrum analyzers), FPGA tools (Vivado/ModelSim), real-time platforms (Speedgoat/dSPACE), schematic capture and PCB CAD tools\nAmazon is an equal opportunity employer and does not discriminate on the basis of protected veteran status, disability, or other legally protected status.\nOur inclusive culture empowers Amazonians to deliver the best results for our customers.
