About Paper
Weight AI

At Paper
Weight AI, we're transforming retail infrastructure with
- thin, intelligent shelf sensors. Our
- based,
- free platform turns every shelf into a
- generating Io
T device and delivers
- time inventory visibility—without shelf replacements, environmental compromise, or complex installs. We’ve launched pilots with leading retailers and are preparing for our global expansion.

We’re looking for an Embedded Systems Engineer with a strong
- on background in Electronics, who thrives on building, optimizing, and iterating in a
- velocity R&D environment.

What You’ll Do

You’ll work closely with our Head of Engineering and expert technical advisors to bring our core sensing devices from lab to scale. You will take ownership of electronics development across prototyping, optimization, validation, and
- readiness.

Your Core Responsibilities

• Design and optimize
  - power analog and digital circuits
• Hands-on prototyping, soldering, and
  - up
• Develop, lay out, and iterate on custom PCBs
• Select and source components considering performance, cost, longevity, and power efficiency
• Collaborate on sensor integration (force, pressure, weight, etc. )
• Debug hardware in the lab (oscilloscopes, multimeters, logic analyzers)
• Develop test jigs and validation routines for QA and reliability testing
• Interface with mechanical, firmware, and manufacturing partners
• Support transition from R&D to DFM / DFA-ready product
• Understand Io
  T system architecture and collaborate with firmware and cloud teams for
  -
  - end device functionality
• Participate in field installations

What You Bring

• BSc or higher degree in Electrical Engineering or a related field
• 3+ years of experience in electronics design within an R&D or prototyping environment
• Strong background in PCB layout, power management, and component selection
• Experience with sensor interfaces, signal acquisition, and calibration
• Proficiency in debugging hardware and building quick iterations in the lab
• Willingness to travel internationally

Bonus points for experience with :

• Embedded electronics or hardware systems development
• BLE / Lo
  Ra and embedded communication protocols
• Low-power design principles (especially for
  - powered systems)
• Flexible or printed electronics
• Ultra-thin or
  - constrained product design
• Manufacturing
  - off and collaboration with fabrication houses

Who You Are

• You thrive in a startup R&D setting
• You can own your domain and work across disciplines
• You’re curious, pragmatic, and biased toward
  - world performance
• Proficient in English – oral and written
• Able to work and collaborate with other disciplines, production partners, and technical mentors
