About Hextronics

Hex is building the infrastructure for on-demand aerial data. We design and manufacture drone-in-a-box systems that automate repetitive drone operations, taking humans out of the loop so the people who depend on aerial data can move faster. We're a small, agile team, we move fast, take on extreme ownership, and build products in months, not years.

The Role

As an Electrical Design Engineer, you'll own electrical components end-to-end — from architecture through schematic, layout, bring-up, and production. You'll drive PCB designs across our drone and dock platforms, write firmware for board bring-up and validation, and partner closely with our hardware team to ship products that work in the real world.

Responsibilities

• Own the end-to-end design process for electrical subsystems — schematic, layout, bring-up, and validation

• Drive schematic capture and multi-layer PCB layout in Altium

• Lead RF design across drone and dock platforms

• Write C/C++ firmware for board bring-up, diagnostics, and hardware validation

• Define and execute verification, validation, and acceptance testing procedures for development and production hardware

• Drive root cause analysis on hardware issues and ship robust solutions

• Propose and validate system architecture decisions through simulation, calculation, and hands-on analysis

• Work cross-functionally with firmware, mechanical, and manufacturing to ensure system-level performance

Requirements

• Bachelor's in Electrical Engineering or related field

• 1-5 years of professional EE experience with a track record of products through a full development lifecycle

• Expert proficiency in Altium for schematic capture and multi-layer PCB layout

• Deep understanding of analog and digital circuit design, power electronics, and high-speed signal integrity

• Hands-on RF design experience - antenna integration, impedance-controlled layout, link budget analysis, and bench testing with VNAs and spectrum analyzers

• Proficiency in C/C++ for firmware development, particularly for board bring-up, diagnostics, and hardware validation

• Strong experience with simulation tools (e.g., SPICE) and analysis to support design decisions

Nice to Have

• Experience with low-power, long-range protocols like LoRa and Wi-Fi HaLow

• Direct experience taking products through FCC and equivalent international regulatory certification

• Expertise in embedded systems architecture with STM32 microcontrollers — peripheral configuration, power management, and debugging

• Experience with Design for Manufacturing (DFM), Design for Test (DFT), and EMI/EMC pre-compliance

• UAV, robotics, aerospace, or defense industry background
  

What We Offer

• Competitive salary and equity

• Comprehensive and highly subsidized medical, dental, and vision benefits for our team and their families

• The chance to work on electrical hardware that controls physical systems in the field

• A small, technical team where your work ships and matters
