Summary

Heatcon develops composite repair controllers serving aerospace, defense, wind energy, and industrial composite repair markets. Our product architecture is built on embedded Linux platforms (ARM-based SoMs), featuring real-time process control, web-driven HMI, secure networking, data logging, and role-based access control.

We are seeking a Software Development Engineer to design and maintain embedded Linux application software for our next-generation controller platform, while also supporting and sustaining legacy products built on Microchip PIC microcontrollers. This role bridges high-level application development with low-level hardware interfacing: you will work closely with our Embedded Systems and Electrical Engineers to integrate hardware drivers, board-level firmware, and real-time control loops with the application layer.

Essential Duties and Responsibilities include the following.

Other duties may be assigned.

Develop and maintain application software on embedded Linux platforms (e.g., Toradex Verdin iMX8M Plus / Torizon OS)

Implement cure execution engine, data logging, recipe/library management, and system diagnostics

Develop system services for USB, Wi-Fi, Ethernet, Bluetooth, and cloud connectivity

Implement user authentication, role-based access control, and device security

Support secure over-the-air (OTA) and offline (USB) software update mechanisms

Implement and tune PID control loops for thermal cure processes

Develop real-time or near-real-time control software with deterministic timing requirements

Apply industrial process control principles to composite repair heating applications

Ensure safe and reliable operation under fault conditions (watchdogs, fail-safes, alarm handling)

TCP/IP networking, HTTP/FTP services, SMTP email notifications

Secure data export via USB and network

Remote diagnostics and telemetry

Device management platform integration using pub/sub messaging and message broker architectures (e.g., MQTT, AMQP, or similar)

Maintain and troubleshoot bare-metal firmware on legacy controller products built on Microchip PIC microcontrollers (PIC16/PIC18/dsPIC)

Diagnose and resolve field issues reported by customers

Port or bridge legacy functionality to the new embedded Linux platform where appropriate

Develop and execute unit, integration, and regression tests

Support compliance validation (UL, IEC, accessibility)

Participate in milestone design reviews

Maintain software revision control (Git) and release documentation

Supervisory Responsibilities

This position does not have supervisory responsibilities, but may provide guidance to less senior members of the engineering staff.

Minimum Qualifications

Strong proficiency in embedded Linux application development

Strong C programming skills, including experience with bare-metal microcontroller firmware

Experience interfacing with hardware peripherals via serial buses (RS-232, RS-485, SPI, I C)

Ability to read electrical schematics and hardware reference documentation

Experience with multi-threaded applications, IPC, and concurrency in resource-constrained environments

Familiarity with real-time or near-real-time control concepts

Preferred Qualifications

Experience with ARM-based Linux SoMs (e.g., NXP i.MX8, Toradex Verdin)

Experience with Microchip PIC microcontrollers (MPLAB X, XC8/XC16 compilers)

Experience writing or modifying custom Linux device drivers and kernel modules

Experience working with ADCs, DACs, and signal conditioning for sensor integration

Hands-on experience with oscilloscopes, logic analyzers, and JTAG/SWD debug tools

Experience implementing and tuning PID con
