Electronics Design Engineer

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 a Senior Electrical Engineer, you'll own electrical components end-to-end — from architecture through schematic, layout, bring-up, and production. You'll drive RF design 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 Ha Low
• Direct experience taking products through FCC and equivalent international regulatory certification
• Expertise in embedded systems architecture with STM
  32 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
• Health, dental, and vision coverage
• The chance to work on electrical hardware that controls physical systems in the field
• A small, technical team where your work ships and matters
