Electronics Design Engineer

About HextronicsHex 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 RoleAs 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.ResponsibilitiesOwn the end-to-end design process for electrical subsystems — schematic, layout, bring-up, and validationDrive schematic capture and multi-layer PCB layout in AltiumLead RF design across drone and dock platformsWrite C/C++ firmware for board bring-up, diagnostics, and hardware validationDefine and execute verification, validation, and acceptance testing procedures for development and production hardwareDrive root cause analysis on hardware issues and ship robust solutionsPropose and validate system architecture decisions through simulation, calculation, and hands-on analysisWork cross-functionally with firmware, mechanical, and manufacturing to ensure system-level performanceRequirementsBachelor's in Electrical Engineering or related field1-5 years of professional EE experience with a track record of products through a full development lifecycleExpert proficiency in Altium for schematic capture and multi-layer PCB layoutDeep understanding of analog and digital circuit design, power electronics, and high-speed signal integrityHands-on RF design experience - antenna integration, impedance-controlled layout, link budget analysis, and bench testing with VNAs and spectrum analyzersProficiency in C/C++ for firmware development, particularly for board bring-up, diagnostics, and hardware validationStrong experience with simulation tools (e.g., SPICE) and analysis to support design decisionsNice to HaveExperience with low-power, long-range protocols like LoRa and Wi-Fi HaLowDirect experience taking products through FCC and equivalent international regulatory certificationExpertise in embedded systems architecture with STM32 microcontrollers — peripheral configuration, power management, and debuggingExperience with Design for Manufacturing (DFM), Design for Test (DFT), and EMI/EMC pre-complianceUAV, robotics, aerospace, or defense industry backgroundWhat We OfferCompetitive salary and equityHealth, dental, and vision coverageThe chance to work on electrical hardware that controls physical systems in the fieldA small, technical team where your work ships and mattersHex is an equal opportunity employer.
