About The Role
Armatrix develops snake-like robotic arms for inspection and intervention in confined and hard-to-reach industrial environments. Our robots integrate multiple motors, motor drives, encoders, sensors, communication buses, power converters, and distributed electronic control systems within mechanically constrained robotic links. Building reliable electronics in this environment requires solving difficult problems involving electromagnetic interference, grounding, coupling, voltage fluctuations, signal degradation, thermal constraints, and system-level electrical reliability. We are looking for a Senior Embedded Hardware Engineer to own these challenges.
At Armatrix, you will work across the full robotics stack, from mechanical design and actuation systems to control - contributing to R&D, prototyping, and deployment of high performance robotic systems that push the boundaries of flexibility, accuracy, and safety. As a Founding Engineer, you’ll shape our core stack, make fundamental design choices, and own systems that will set new benchmarks for what’s possible in robotics.
Responsibilities and Duties
You will own the electrical robustness of Armatrix’s robotic systems. Your primary responsibility will be to ensure that motors, motor drives, encoders, sensors, embedded controllers, communication networks, and power systems operate reliably together despite electrical noise, switching transients, long cable runs, compact packaging, and changing load conditions. This is not primarily a firmware-development role. A separate embedded software engineer will own low-level firmware and device drivers. You will work closely with that engineer to define hardware interfaces, debugging provisions, electrical limits, and system-level mitigation strategies. You will be expected to identify the root cause of difficult electrical failures and redesign the hardware or system architecture so that the problem does not recur.
Electronic System Integrity
- Diagnose and resolve conducted and radiated EMI, including capacitive, inductive, and common-impedance coupling across motors, drives, power electronics, sensors, communication buses, and control circuits.
- Ensure reliable operation of communication and feedback interfaces such as EtherCAT, CAN, RS-422, BiSS-C, SSI, SPI, UART, Ethernet, and differential encoder links. Analyze signal rise times, reflections, ringing, impedance discontinuities, termination, skew, jitter, and crosstalk.
- Design and validate power-distribution architectures for motors, motor drives, embedded controllers, encoders, sensors, and end effectors.
- Design and review mixed-signal embedded PCBs used in robotic systems. Hardware Debugging and Root-Cause Analysis
- Lead investigation of intermittent electrical issues such as unexplained resets, encoder jumps, communication errors, sensor drift, and unstable measurements.
- Build test setups that simulate motor switching, cable length, actuator loading, supply fluctuations, and external disturbances.
Minimum Qualifications
- Bachelor’s or Master’s degree in Electrical Engineering, Embedded Systems, or a related field.
- Proven experience in circuit simulation, PCB design, and debugging techniques.
- Basic familiarity with communication protocols and related hardware challenges.
- Experience with RTOS and real-time firmware design is highly desirable.
- Hands-on expertise with simulation tools (e.g., LTSpice, PSpice) and PCB design software (Altium, Eagle, KiCad).
- Strong professional experience designing and debugging embedded electronic hardware.
- Demonstrated experience resolving EMI, grounding, coupling, signal-integrity, or power-integrity problems.
- Strong understanding of analog and digital circuit design.
- Ability to debug systems using oscilloscopes, differential probes, current probes, etc.
Benefits
- Competitive compensation
- Flexible work timings
- Medical Insurance
- Relocation Assistance (if applicable)
