About the Role

ConnectDER is seeking a hands-on technical lead for its firmware engineering team. This role involves owning the device software system end-to-end, defining architecture, breaking down work, and driving iterative delivery. You will write production code and delegate tasks, focusing on the IslandDER digital interface which complies with a new device-to-device communication standard.

Responsibilities

Own the overall device software architecture.
Break complex requirements into well-scoped workstreams, delegate with clean interfaces, and guide the team while staying hands-on.
Architect and implement the safety-critical software, owning the FMEA, safety case, and NRTL certification.
Design and implement revenue-grade metering systems, including data acquisition, signal processing, and calibration.
Partner with electrical engineering to co-define requirements, drive board bring-up, debug across the boundary, and influence hardware design.
Own the secure firmware-update path, including secure boot, code signing, and the key-management system.
Maintain a modern CI/CD pipeline and testable code.
Take systems from prototype to mass production.

Requirements

Bachelor's degree in Electrical Engineering, Computer Engineering, or Computer Science.
7+ years in firmware engineering with a track record of shipping new products at scale.
Exacting commitment to clear, thorough technical documentation and design diagrams.
Discipline to drive a complex safety certification (e.g., IEC 61508 / IEC 60730 / UL 1998) to completion.
Experience leading the technical direction of a project, architecting the approach, partitioning workstreams, and shipping code.
Expert in C, C++, and/or Rust.
Deep experience debugging embedded systems via oscilloscopes, logic analyzers, and JTAG/SWD.
Deep bare-metal/RTOS firmware experience on modern 32-bit microcontrollers (ARM Cortex-M or similar), including low-level architecture and multi-core memory optimization.
Sophisticated use of AI coding agents paired with full ownership; ability to explain every significant decision shipped.
Bias for fast iteration and judgment to size effort to business value.
Communication skills to explain complex requirements to diverse stakeholders.
Master's degree in Electrical Engineering, Computer Engineering, or Computer Science (Preferred).
Prior experience taking safety-critical software through NRTL certification (Preferred).
Matter/Thread device commissioning (SPAKE2+/PASE, setup-code or QR pairing) (Preferred).
Experience with I2C, UART, SPI, CAN/CAN-FD, and Ethernet (Preferred).
Experience with build systems (Make, CMake) (Preferred).
Experience with test automation and CI/CD (Preferred).
Embedded TCP/IP networking (e.g., lwIP); experience implementing WireGuard or similar secure tunnels on a real-time embedded platform (Preferred).
Reverse-engineering CAN protocols or developing custom evaluation tools (Preferred).
Experience configuring and using an RTOS for multi-threaded, timing-critical applications across metrology, safety, and communications (Preferred).
Experience with PX5 or ThreadX (Preferred).
Experience designing or operating a code-signing / PKI system for firmware (key custody, signing pipeline, secure boot verification, key rotation and revocation) (Preferred).
Familiarity with relevant standards, e.g., UL 1741/IEEE 1547, UL 3141, UL 2900 (cybersecurity), and ANSI C12.1 (metering) (Preferred).
Selected candidates must pass a criminal history background screening and a reference check.
Must be able to show proof of work authorization.
