Firmware Engineer Remote Internship Jobs in Virginia

Senior Embedded Engineer - Smart energy systems - Remote!

Senior Embedded Firmware Engineer (100% Hands-On IoT)

Location: 100% Fully Remote (EST Timezone Preferred)

Compensation: $145,000 - $190,000 Base Salary + Full Benefits

Role Type: Permanent, Full-Time Individual Contributor (IC)

About the Opportunity

We are a rapidly growing, private equity-backed technology leader building intelligent networks of connected commercial infrastructure. Our IoT platform harnesses real-time edge telemetry and automated automation systems to optimize operations and deliver resource efficiency for enterprises and utilities nationwide.

We are looking for a hands-on Senior Embedded Firmware Engineer to join our newly restructured engineering team. This is a 100% technical individual contributor role with zero people management. You will focus entirely on designing, implementing, and deploying low-level C/C++ code that interfaces directly with physical silicon and microcontrollers on custom circuit boards.

If you thrive on bare-metal architecture, device-to-cloud telemetry, and debugging physical hardware, this role offers complete technical ownership in a stable, fully remote environment.

What You Will Do

• Firmware Development: Write highly efficient, real-time code in C/C++ for resource-constrained, microcontroller-based IoT hardware nodes.

• Driver Architecture: Design and maintain low-level device drivers for onboard sensors, actuators, and various wired/wireless communication modules.

• System Integration: Develop secure telemetry pipelines and robust Over-the-Air (OTA) firmware update streams to push cloud-managed upgrades using protocols like MQTT and HTTP/HTTPS.

• Hardware Debugging: Troubleshoot physical board-level issues and analyze system architecture using JTAG/SWD, oscilloscopes, and logic analyzers.

Absolute Requirements (Must-Haves)

To be successful, candidates must have a foundational understanding of physical hardware and electronic systems. Profiles focused purely on application-level or desktop software development cannot be considered.

• Education: Bachelor's degree in Electrical Engineering, Computer Engineering, Computer Science, or a related technical field.

• Core Experience: 5+ years of embedded firmware development paired with 3+ years of hands-on IoT systems engineering.

• Languages: High proficiency in C/C++ for embedded targets, and Python for custom internal scripting and tooling.

• Microcontrollers: Production experience working directly with ARM Cortex-M, STM32, Microchip, or similar hardware platforms.

• Hardware Protocols: Hands-on experience with physical serial communication layers: SPI, I2C, UART, RS-485, USB, and Ethernet.

• Operating Systems: Direct development experience utilizing an RTOS (FreeRTOS, Zephyr, or similar) AND building embedded Linux systems via Buildroot.

• Diagnostic Tools: Deep comfort using physical laboratory equipment to isolate firmware defects (JTAG, SWD, oscilloscopes, and logic analyzers).

Preferred Skills

• Exposure to industrial automation, building automation networks, or energy management systems.

• Familiarity with wireless communications (Wi-Fi, Bluetooth/BLE, LoRa/LoRaWAN, or cellular integration).

• Networking protocols like Modbus, CoAP, and TCP/IP stacks.

• Experience with embedded GUI development utilizing tools like LVGL or TouchGFX.

Benefits

• Mission-Driven: A rewarding career directly combating climate change.

• Growth Industry: Stable, well-funded company in the booming green-tech and utility tech sectors.

• Comprehensive Benefits: Competitive pay, full health/wellness coverage, and 401(k).
