Full Job Description
We are seeking an Electrical Hardware Engineer to design, develop, and test hardware for our access control readers and controllers. You will join a small hardware team, report to the Lead Electrical Engineer, and work closely with firmware, product, manufacturing engineering, validation, and our PCBA CMs.
You will work alongside the Lead Electrical Engineer on every stage of development, from architecture and component selection through production release, and take ownership of your own projects over time. The work spans RF, power, digital, and PCB layout across the entire design lifecycle, and you will see your designs ship as products in the field.
Duties/Responsibilities
Create schematics and PCB layouts, and select components based on cost, lifecycle status, and supply risk
Simulate and analyze circuits to verify designs before and after layout
Tune antennas and characterize RF performance for 125 kHz, 13.56 MHz HF, and BLE interfaces
Bring up prototypes and characterize power rails and digital interfaces
Run environmental tests and EMC/ESD pre-compliance scans
Write design documentation, test reports, and troubleshooting guides
Support production at our PCBA CMs by reviewing build reports, resolving assembly defects and yield issues, and root-causing production test failures
Support manufacturing engineering, firmware, and validation teams on DFX, production test fixtures, security validation, and interoperability testing
Troubleshoot hardware issues in production and in the field
Required Skills/Abilities
Bachelor's degree in Electrical Engineering, Computer Engineering, or a related field
2+ years of embedded hardware experience. Internships, co-ops, and graduate research in hardware design count toward this.
Experience with schematic capture and PCB layout tools
Knowledge of microcontrollers (e.g., ARM Cortex-M) and interfaces such as Ethernet, RS-485, I2C, SPI, and UART
Understanding of power supply design, including buck/boost converters and LDOs
Familiarity with RF and wireless technologies (e.g., Bluetooth, NFC, RFID)
Hands-on experience with oscilloscopes and logic analyzers
Ability to work independently and communicate clearly with firmware, product, and manufacturing teams
Willing to travel domestically and internationally, 5 to 20 days per year
Nice to Haves
Experience working with PCBA contract manufacturers, including prototype and production builds
Experience owning the design of a hardware product through production
Antenna design and RF tuning experience for 125 kHz, 13.56 MHz, or 2.4 GHz interfaces
Direct background in the Physical Access Control System (PACS) industry
Familiarity with OSDP, secure elements, and cryptographic hardware
Experience with design for manufacturing (DFM), design for test (DFT), and cost optimization
Hands-on experience with spectrum analyzers and VNAs
Experience with environmental, EMC, and ESD testing
Knowledge of embedded firmware development in C/C++
Experience with Altium Designer
Experience with signal integrity, power integrity, thermal, or RF simulation
