About Prosperous Research Systems

Prosperous Research Systems (PRS) is building a research-grade, contactless brain-computer interface platform for assistive communication and intent-to-output interaction. Our system uses ultrasonic sensing, RF sensing, and machine learning to explore whether intent-related signals can be captured without implants, caps, gels, or wearable headsets.

We are currently approaching MVP and are looking for an electrical engineer to help us iterate our PCB/prototype and move toward a more repeatable, pilot-ready hardware design.

Role Overview

We are seeking an Electrical Engineer with strong PCB design, mixed-signal electronics, and sensor hardware experience to support the next phase of our prototype. This person will help refine our hardware architecture, improve signal acquisition quality, and design/iterate PCB layouts for contactless ultrasonic + RF sensing.

The ideal candidate is comfortable working in an early-stage startup environment where the work involves technical problem-solving, rapid iteration, and translating an experimental concept into a cleaner, more reliable prototype.

Responsibilities

• Design, review, and iterate PCB layouts for PRS’s contactless sensing prototype
• Support mixed-signal circuit design involving analog front-end, digital control, and sensor interfaces
• Assist with ultrasonic transducer driver/receiver circuitry and RF sensing considerations
• Improve signal integrity, grounding, shielding, power management, and noise reduction
• Help select components, sensors, microcontrollers, ADCs/DACs, and supporting circuitry
• Collaborate with the founder and technical partners to define hardware requirements
• Support prototype bring-up, debugging, bench testing, and hardware validation
• Document design decisions, test results, and next-step recommendations
• Prepare the hardware design for future manufacturability and pilot deployment

Ideal Background

• Electrical Engineering, Computer Engineering, or related technical background
• Experience designing PCBs in KiCad, Altium, Eagle, or similar tools
• Strong understanding of mixed-signal circuit design
• Experience with RF systems, antennas, impedance matching, shielding, or low-noise signal acquisition
• Experience with ultrasonic transducers, sensor arrays, biomedical instrumentation, or embedded sensor systems is a major plus
• Familiarity with microcontrollers, ADCs, DACs, SPI/I2C/UART, and embedded hardware interfaces
• Comfortable using oscilloscopes, logic analyzers, signal generators, and other bench tools
• Interest in neurotechnology, assistive communication, BCI, HCI, or accessibility technology

Nice to Have

• Experience with RF/microwave sensing, radar, mmWave, or bio-signal sensing
• Experience with ultrasound hardware or acoustic sensing systems
• Experience with wearable, medical, or research-grade device prototyping
• Familiarity with signal processing, ML data pipelines, or sensor fusion
• Prior startup, research lab, or rapid prototyping experience

Why Join PRS

This is an opportunity to help shape the hardware foundation of a new contactless BCI platform from the ground up. You would play a key role in moving PRS from prototype design toward a functional MVP and early research pilots.

We are especially interested in someone who wants to contribute meaningfully to assistive communication technology and help build tools that may one day support people with severe communication and motor limitations.

Compensation

PRS is an early-stage, pre-seed startup. Compensation structure is flexible and may include contract pay, equity, milestone-based compensation, or a combination depending on fit, availability, and experience.

How to Apply

Please send a short note describing your relevant PCB, RF, ultrasonic, sensor, or embedded hardware experience. Links to past hardware projects, GitHub, portfolio, publications, or PCB examples are encouraged.
