About FluidLogic

At FluidLogic, we're reimagining how humans hydrate. Our Intelligent Hydration systems combine cutting-edge hardware with powerful software to optimize performance, health, and recovery—starting with elite athletes and expanding to everyday adventurers. We believe the future of wellness is precision-driven, personalized, and always evolving—and we're just getting started.

About the Role

We are seeking a Senior Electrical / Hardware Systems Engineer to lead the design and development of embedded hardware systems from concept through production. This role requires strong system-level thinking and hands-on execution across power, sensing, actuation, and communication systems. You will help define hardware architecture, design critical circuits, lead bring-up and debugging, and support scaling products into manufacturing.

This is a role for an engineer who enjoys owning complex systems end-to-end, thrives in fast-moving environments, and is comfortable working across disciplines to bring real products to life.

The ideal candidate is comfortable working across power, digital, and mixed-signal domains, and can design, debug, and scale complex embedded systems in a highly collaborative, cross-functional environment.

What You'll Do

System Architecture & Hardware Development

Define and drive system-level hardware architecture, including partitioning across core subsystems and expansion modules
Design embedded hardware systems including schematics, component selection, and PCB layout guidance
Develop robust power architectures including battery systems, switch-mode power supplies (buck/boost), sequencing, and protection
Design and integrate motor drivers and actuator systems, including power delivery and control considerations
Contribute to development of scalable platform architectures supporting multiple product variants

Hardware Bring-Up & Debugging

Lead hardware bring-up, debugging, and validation of prototypes and production hardware
Perform root-cause analysis of complex hardware issues across power, sensing, and communication systems
Identify and resolve noise coupling issues across mixed-signal systems (power, RF, sensing, and digital domains)
Drive EMI/EMC and ESD design and debugging, including grounding strategy, return path control, shielding, and interface protection

System Integration

Collaborate closely with firmware, mechanical, and product teams to ensure cohesive system integration
Support integration of microcontrollers, sensors, wireless modules, and communication interfaces
Help identify and mitigate system-level risks across electrical, mechanical, and firmware boundaries

Manufacturing & Productization

Support transition from prototype to production, including DFM/DFT and production readiness
Help define manufacturing test strategies and validation processes
Evaluate engineering tradeoffs across cost, performance, reliability, and manufacturability

What Success Looks Like in This Role

Develop a deep understanding of the system architecture, design constraints, and product requirements
Take ownership of key hardware subsystems, driving design improvements and resolving critical technical issues
Lead hardware bring-up, debugging, and validation of new prototypes and iterations
Identify and reduce system-level risks related to power integrity, EMI, signal integrity, and system integration
Contribute to improving hardware reliability, manufacturability, and scalability as the product moves toward production
Communicate clearly across engineering disciplines and build strong working relationships with firmware, mechanical, and manufacturing teams

What You'll Bring

Bachelor’s or Master’s degree in Electrical Engineering or related field
7+ years of experience in hardware design and embedded system development
Demonstrated experience bringing hardware products from concept through production
Strong experience with mixed-signal embedded systems
Experience designing switch-mode power supplies, battery-powered systems, and power distribution
Experience with motor drivers, actuators, or other electromechanical systems
Strong debugging skills across hardware and system-level issues
Proven ability to diagnose and resolve EMI/EMC and ESD issues in complex systems
Solid understanding of noise coupling mechanisms, return path control, grounding strategies, and protection design
Experience working in cross-functional teams including firmware, mechanical, and manufacturing

Preferred

Experience with portable or battery-powered systems
Experience with wireless systems (BLE, NFC, or similar)
Familiarity with manufacturing test development and production scaling
Experience designing platform architectures across multiple product variants
Experience working in consumer electronics or connected device environments

Tools & Technologies

ECAD tools such as Altium Designer (or similar)
Lab equipment including oscilloscopes, logic analyzers, spectrum analyzers, and power measurement tools
Experience debugging embedded systems using MCUs and common communication interfaces (SPI, I2C, UART, etc.)
