Sr. Staff Electrical Systems Architecture & Integration Engineer – Space Systems

Sr. Staff Electrical Systems Architecture & Integration Engineer – Space Systems

Requirements

• Bachelor’s degree or higher in a STEM area (Science, Technology, Engineering or Math) and 14 years of relevant work experience, 12 years of relevant work experience with a Master’s degree or 10 years of relevant work experience with a PhD.
• Extensive Electrical Engineering background with an understanding of analog and digital electronics, power systems, Command and Data Handling, Signal Integrity, and Grounding schema
• Technical experience in systems engineering and integration
• Hands-on mentality and a passion for fast-paced environments
• Must have ability to obtain and maintain TS/SCI Clearance

Responsibilities

• Develops and evaluates flight-vehicle electrical system architecture alternatives in concert with the broader systems engineering effort to select an electrical-system architecture that meets the customer’s needs. Drive open design to completion and solve design issues (e.g. propose solutions, support mass reduction initiatives)
• Performs electrically focused requirement analysis and decomposition as part of the systems engineering translation of customer requirements into hardware and software specifications.
• Performs analyses to evaluate all levels of the system to ensure a cohesive electrical-system solution throughout the development lifecycle (concept, design, fabrication, test, installation, operation, maintenance, and disposal).
• Manages the internal & external flight-vehicle electrical interfaces (such as data, power, RF) and develops the corresponding system-level interconnect/block diagrams, grounding diagrams, electrical schematics and global connectivity list for the flight vehicle.
• Oversees the technical planning, design integration, product integration, verification, and validation efforts for the electrical-system elements throughout the development lifecycle. Influences the electrical-system design to facilitate electrical testing at the component, subsystem, and flight-vehicle levels, with the aim to enable automated testing where applicable.
• Perform electrical interface compatibility verifications (e.g. check component external interfaces compatibility including interconnecting harness, sneak circuit analysis)
• Perform power management verifications – analyses and documentation (e.g. voltage drop, round trip resistance, impedance, power stability, circuit protection, electrical load analysis)
• Development system-level electrical verification (e.g. method, objective, event, activity, success criteria, author test plan)
• Review suppliers ‘as-planned’, ‘as-designed’, and ‘as-built’ documentation (e.g. interface control document, derating analysis, worst case analysis, qualification test plan and procedure, acceptance test plan and procedure, test report)
• Conduct characterization and risk reduction tests (e.g. evaluate test methods)
• Manage hardware command and telemetry implementation (e.g. develop and coordinate calibration and conversion curves for analog telemetry in coordination subsystem engineers, verify electrical/software implementation)
• Verify electrical connectivity implementation (e.g. verify electrical harness implementation, safety-critical circuit segregation, support peer-reviews)
• Support physical layer verification (e.g. signal integrity)
• Contribute to assembly integration and test activities (e.g. harness integration and testing, electrical test requirements development, anomaly investigations/resolutions)
• Document verification activities (e.g. review test artifact, author test report, prepare verification closure notice)
• Identify electrical systems risks, develop risk mitigation plans for selected risks, and implement mitigations
• Collaborate and communicate effectively with team members from multiple subsystems and Subject Matter Experts (SME) to achieve integrated solutions. This can include Program Management (PM), Chief Engineer (CE), Lead Systems Engineer (LSE), Electronic Power Systems (EPS), Command and Data Handling (CDH), Integration and Test (I&T), early career individuals and customer counterparts at various levels.

Preferred Qualifications

• Knowledge of power converter topologies, micro-grid, grid-connected power electronics, grid-connected batteries
• Knowledge of complex system interfacing, signal integrity, power loss
• Knowledge of component to space vehicle electrical system grounding schema, isolation, ground loops and characterization, power quality and EMI/EMC testing
• Understanding of switching waveforms, semi-conductor losses and experience with loss modeling
• Experienced with data bus (Ethernet, SpaceWire, RS-422, RS-485, MIL-STD-1553) and troubleshooting
• Experienced with signal acquisition (filtering, Analog to Digital Converter)
• Experience with space-vehicle RF subsystem and RF/electrical interfaces with the rest of the system
• Familiarity with functional specification, state machines, and FMEA (Failure Mode Effect and Criticality Analysis)
• Model-based design and test background (e.g. Simulink, SPICE, AMESim, Saber, LabView)
• Experience in System Modeling Language (SysML) using Cameo or other system modeling tools
• Development and operations of hardware-in-the-loop simulators, conducting testing and troubleshooting of hardware and software interfaces
• Experience on prime integrated systems (not just component/subsystem).
• Full program lifecycle experience (requirements through integration/test/verification).
• Experience in electrical manufacturing (e.g. board, unit, harness)
• Current or active TS/SCI Clearance
