Embedded Software (Firmware) Design Engineer - Mid / Senior level

Tri‑Tec is seeking a Mid to Senior Embedded Software Firmware Design Engineer with seven to ten years of experience developing embedded systems for electromechanical products in an R and D environment. This role requires strong embedded‑software capability, hands‑on electrical and PCB‑level knowledge, and the ability to design and implement sensor‑data processing functions that support advanced actuator control.

You will collaborate with Senior Electrical, Software, Firmware, and Mechanical Engineers to design, implement, troubleshoot, validate, and maintain embedded software and firmware for valve actuators installed aboard current and future United States Navy Destroyers, Frigates, Submarines, and Aircraft Carriers.

Responsibilities include embedded‑control development, sensor‑data acquisition and processing, communication‑interface implementation, and system‑level integration.

This position is contingent upon award of contract. If the anticipated contract is awarded, official hiring date would be in January/February 2027.
