Full Job Description

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.

Additional responsibilities include participation in configuration management, testing, qualification, and continuous improvement of both legacy and newly developed software. You will contribute to innovative and patentable technologies and support all phases of product development within a small, highly collaborative engineering team.

Requirements
Seven to ten years of embedded‑software design experience
Fluency in the C programming language
Experience writing code for embedded microprocessors and microcontrollers
Strong understanding of debugging fundamentals and use of debugging tools
Experience developing sensor‑data acquisition pipelines and implementing sensor‑data processing algorithms for embedded systems
Strong electrical and PCB‑level knowledge suitable for an R and D environment including schematic interpretation, signal‑integrity considerations, and hardware bring‑up
Understanding of standard communication protocols and microcontroller peripherals including GPIO, I2C, SPI, UART RS‑232 and RS‑485, CAN, timers, counters, PLLs, reset generators, clocking, power management, ADCs, and PWM
Ability to work collaboratively to solve complex engineering problems
Bachelor’s degree in Electrical Engineering (preferred), Computer Engineering (second), Computer Science (third)
Preferred Experience
NXP ARM processor
Designing/testing to the requirements of quality and reliability standards such as DO-178, SS-473
Fieldbus (Profibus, Modbus) and fiberoptic communications
Configuration Management practices and tools
Electromechanical actuators and motion control systems
In-depth troubleshooting and debugging of assembly level code, off-board/inter-IC communication, signal integrity, power, PCB, and other hardware related problems
Experience in hands-on R&D environments including prototyping, bench testing and iterative design.
Qualifications
US citizenship is mandatory due to defense contracts requirements. Background check will be performed.
Minimum bachelor’s degree in Electrical Engineering (preferred), Computer Engineering (second), Computer Science (third)
7 to 10 years of Embedded Software Design work experience
Must have strong English reading and writing skills

Pay: $125,000.00 - $140,000.00 per year
