Senior Engineer – Electrical – Sensing and Communication Systems (REQ 347)

Overview: Applied Physical Sciences (APS) is seeking a skilled Senior Electrical Engineer to support the development of an advanced inductive power and data acquisition system for maritime applications. This position focuses on designing a robust, low‑noise, high‑integrity DAQ system that operates across an air‑gapped inductive power and communications interface. The ideal candidate has deep experience in mixed‑signal electronics, precision data acquisition, power electronics, magnetics, and embedded communications, along with a demonstrated ability to deliver reliable hardware solutions for harsh or mission‑critical environments. The selected engineer will work within and help guide a multidisciplinary team developing technology intended for US Navy deployment, where high reliability, data fidelity, and environmental resilience are essential. APS provides a dynamic small‑company environment that rewards technical excellence, fosters innovation, and encourages engineers to collaborate directly with teammates and customers. Job Functions and Responsibilities

• Lead the architecture, design, and validation of a low noise, high reliability data acquisition system powered and communicated through an inductive airgap link.
• Develop analog front end circuitry, including high resolution ADC interfaces, filtering networks, clocking, low noise preconditioning, and signal integrity safeguards.
• Design and optimize inductive power transfer systems, including coil and magnetics design, high efficiency driver stages, rectification, regulation, and DC/DC power conversion.
• Implement and validate digital communication methods over an inductive link (modulation schemes, encoding, error correction, data integrity strategies).
• Oversee custom analog/digital PCB development, including schematic ownership, layout review, and compliance with mixed signal best practices.
• Integrate DAQ, power, and communication subsystems into electromechanical assemblies intended for maritime or underwater operation.
• Perform system level troubleshooting and refinement using laboratory instrumentation such as oscilloscopes, multimeters, function generators, and digital probes.
• Collaborate closely with embedded software engineers to ensure correct firmware behavior, sequencing, timing, configuration, and fault reporting across the inductive interface.
• Mentor junior engineers and contribute technical leadership during design reviews, architecture discussions, and prototype evaluations.
• Prepare and present documentation, test plans, analyses, and technical briefings to internal stakeholders and external customers.
• Support field testing and technology demonstrations as needed (up to 10% travel).

Required Skills and Attributes

• BS in Electrical Engineering with 5+ years of relevant experience, or MS with 3+ years’ experience, or PhD with no industry experience. Concentration in mixed signal design, power electronics, or data acquisition systems.
• Expertise designing low noise analog circuitry, including sensor interfaces, ADC based DAQ chains, grounding schemes, and noise floor optimization.
• Demonstrated experience designing high power or high efficiency electronics, including DC/DC converters, magnetics, MOSFET/IGBT based stages, and power amplifiers.
• Strong background in mixed signal PCB design, component selection, and layout review for noise sensitive and high reliability systems.
• Proficiency with microcontrollers, embedded processors, and digital communication interfaces (SPI, I2C, RS422, etc.).
• Experience designing or qualifying electronics for harsh environments, including EMI/EMC considerations and environmental tolerance.
• Strong laboratory-based debugging skills and the ability to diagnose complex system interactions.
• Strong communication skills with the ability to present technical concepts clearly to multidisciplinary teams and customers.
• Able to obtain and maintain a Secret Security Clearance

 Preferred Skills and Attributes

• Experience designing hardware for underwater maritime systems or other mission critical applications.
• Prior experience developing inductive power transfer or magnetic coupling systems.
• Familiarity with Altium Designer for schematic capture and layout review.
• Experience with LTSPICE, MATLAB, or other circuit modeling and data analysis tools.
• Experience mentoring junior engineering staff or leading design teams.
• Familiarity with electromechanical systems, acoustic sensors, or underwater transducer technology.
