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.

APS, a wholly owned subsidiary of the General Dynamics Corporation, offers competitive salaries, excellent benefits, and comfortable working conditions. Candidates must possess or be able to obtain a DoD security clearance. Please note, obtaining a security clearance is a condition of employment which typically requires US citizenship and a thorough background investigation.
