About the Role

This role is an opportunity to take a technical leadership position within Hidonix’s R&D organization, owning the electrical architecture behind our next-generation robotics systems. As a Senior Electrical Engineer, you will drive system-level design decisions, lead complex hardware development efforts, and mentor engineers while remaining deeply hands-on.

The ideal candidate will design advanced multi-layer PCBs, power systems, RF subsystems, and sensor integrations, taking products from early concept through validation and into low-volume production. This role works closely with mechanical, firmware, robotics, and product teams and is ideal for an engineer who thrives on ownership, rigor, and building hardware that ships.

Role & Responsibilities

Electrical Architecture & PCB Leadership

• Own system-level electrical architecture for complex embedded and robotic platforms.
• Lead end-to-end design of high-complexity, multi-layer PCBs — from schematic capture through layout oversight, fabrication, validation, and revision.
• Define board stack-ups, impedance requirements, power-domain partitioning, and interface strategies for high-performance ARM-based systems.
• Set component selection strategy, qualify critical parts, maintain BOMs, and guide vendor engagement through prototype and low-volume production.
• Review and approve schematics, layouts, and design changes across multiple boards or subsystems.

Power Systems & Battery Architecture

• Architect robust, high-efficiency multi-rail power delivery systems supporting processors, sensors, motors, and communication modules.
• Lead lithium-polymer battery management, charging, protection, and safety architecture for portable and wearable robotic systems.
• Analyze and optimize power integrity, transient behavior, thermal performance, and system efficiency under real-world operating conditions.
• Guide power-related trade studies and risk assessments.

RF & High-Speed System Design

• Own RF subsystem architecture, including antenna strategy, coexistence planning, and module integration for Wi-Fi, Bluetooth, GNSS, and cellular.
• Lead high-speed interface design (DDR, eMMC, USB, MIPI, PCIe where applicable), ensuring signal integrity across complex stackups.
• Use VNAs, spectrum analyzers, SI/PI simulation tools, and lab measurements to validate and optimize RF and high-speed performance.
• Drive EMI/EMC mitigation strategies early in the design cycle.

Sensor, Peripheral & System Integration

• Architect and integrate IMUs, GNSS receivers, barometers, cameras, and other sensing subsystems into low-noise, high-reliability designs.
• Design and review analog front ends, signal-conditioning circuits, protection networks, and grounding strategies.
• Lead performance benchmarking, environmental testing, and design iteration for robustness and manufacturability.

Prototype Bring-Up, Validation & Debug

• Lead prototype bring-up, electrical validation, and design verification at board and system levels.
• Drive structured root-cause analysis for complex hardware failures and guide corrective design actions.
• Set validation strategies, test plans, and acceptance criteria aligned with product and system requirements.
• Collaborate closely with mechanical, firmware, and robotics teams to ensure tight electromechanical integration.

Technical Leadership & Collaboration

• Mentor and technically guide mid-level and junior electrical engineers.
• Lead design reviews and contribute to engineering standards, best practices, and documentation quality.
• Maintain rigorous design documentation, revision control, and release artifacts.
• Participate in roadmap planning, architectural discussions, and cross-functional technical decision-making.

Required Qualifications

• Bachelor’s or Master’s degree in Electrical Engineering, Electronics, or a related field.
• 7–10 years of professional experience in embedded hardware, robotics, or complex electronic systems.
• Deep expertise in multi-layer PCB design and review (Altium, KiCad, or equivalent), including controlled impedance and high-speed layout.
• Strong foundation in analog and digital circuit design, power electronics, and signal integrity.
• Demonstrated experience leading RF design and antenna tuning with lab-based validation.
• Advanced hands-on experience with oscilloscopes, VNAs, spectrum analyzers, logic analyzers, and power analyzers.
• Proven ability to lead complex hardware projects from concept through validation.
• Excellent documentation, communication, and cross-functional collaboration skills.

Preferred Qualifications

• Experience with DDR and other high-speed memory interfaces and SI/PI simulation workflows.
• Strong background in DFM/DFA, EMC/EMI compliance, and thermal design.
• Experience supporting product certification and regulatory validation.
• Prior experience mentoring engineers or acting as a technical lead.
• Hands-on prototyping, soldering, and rework experience with fine-pitch components.

Other Requirements

• Must be a U.S. Citizen or permanent Green Card holder.
• Must be within commuting distance of Santa Monica, CA.

Why Join Hidonix

• Take ownership of core electrical architecture for cutting-edge robotics systems.
• Work with a top-tier, multidisciplinary R&D team.
• Collaborative, high-trust engineering culture with real technical influence.
• Fast-paced, innovation-driven environment that values depth and rigor.
• Flexible PTO and comprehensive benefits supporting work–life balance.
• Competitive salary: 125-130K annually, depending on experience.
