Electrical Engineer

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.
