  • Deep expertise in analog, digital, and mixed-signal circuit design, including schematic capture, PCB layout guidance, and component selection 
  • Strong proficiency with Altium Designer or similar professional PCB design tools 
  • Demonstrated experience architecting and delivering battery-powered embedded systems, including power management, DC-DC conversion, Li-ion battery management, and charging circuitry 
  • Experience designing systems using microcontrollers and embedded firmware interfaces, with working knowledge of C-based firmware development 
  • Strong understanding of common embedded communication protocols including USB, I²C, SPI, UART, and BLE 
  • Experience performing electrical analysis and simulation, including signal integrity, power integrity, and noise mitigation in compact electronic systems 
  • Experience designing for and supporting EMC/EMI compliance and testing, including familiarity with IEC 60601, EN 61326, or comparable standards 
  • Demonstrated experience delivering hardware–software integrated products from early concept through verification, validation, and commercialization 
  • Experience working within regulated development environments, including familiarity with FDA design controls, design history files (DHF), and traceable engineering documentation 
  • Exceptional hands-on engineering capability, with a proven ability to troubleshoot complex electrical and system-level issues 
  • Ability to produce clear, rigorous engineering documentation including design analysis, test reports, verification protocols, and design rationale 
  • Strong communication and collaboration skills across multidisciplinary teams including firmware, mechanical engineering, product management, clinical, and manufacturing teams 
  • Ability to communicate complex technical concepts clearly to both engineering peers and executive leadership 

Preferred Qualifications: 

  • M.S. in Electrical Engineering or a related technical field 
  • Experience developing wearable medical devices or compact battery-powered consumer electronics 
  • Experience designing low-power embedded systems for continuous or wearable operation 
  • Experience working within medical device quality systems and regulated product development processes (e.g., FDA design controls, ISO 13485) 
  • Demonstrated success leading complex hardware programs from early development through commercialization 
  • Experience collaborating with contract manufacturers and external development partners during product development and manufacturing scale-up 

Compensation: 

  • Base pay: $140,000–$160,000 per year + bonus + stock option

Race & Ethnicity Definitions

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
