Job Senior Firmware Engineer

Senior Firmware Engineer

Join AMETEK Power Instruments, an innovative leader in electronic instrumentation for the electric utility and process industries. We specialize in delivering top-tier products like fault recorders, annunciators, and turbine engine sensors that measure and monitor power generation, transmission, and end-user assets. If you're ready to make a real impact in the energy and manufacturing sectors, we invite you to bring your expertise and passion to our team.

We are developing the next generation of our high-accuracy revenue metering platform for generation, transmission, and industrial power measurement. We are seeking a hands-on Senior Firmware Engineer to work shoulder-to-shoulder with our hardware design team through the full development cycle — from schematic review and board bring-up to a shipping, field-deployable product.

• Hands-on embedded Linux development: building and configuring the kernel, writing and debugging device drivers, and working with a board support package (BSP); experience with Yocto, Buildroot, or a comparable build system
• Board bring-up of new hardware in close partnership with HW designers — powering up first articles, validating power rails, clocks, resets, and boot, and triaging early hardware/firmware issues
• Low-level lab debugging and probing: confident use of oscilloscopes, logic analyzers, JTAG/SWD debuggers, multimeters, signal generators, and bus decoders to root-cause issues at the signal level

• 10+ years of hands design experience such as below.
• Proven experience writing firmware applications in C/C++ for timing critical requirements.
• Designing and implementing low-level serial interfaces and protocols — UART, SPI, I2C, and similar.
• In-circuit and source-level debugging with GDB and IDE-based debug tools (e.g., Eclipse, VS Code).
• GCC/G++ tool chains and cross-development workflows (Linux- and Windows-hosted).
• Understanding of embedded memory architecture: program flash, RAM, nonvolatile storage, and file systems.
• Ability to read and interpret electronic schematics.
• Solid grasp of signal processing fundamentals, including frequency-domain analysis (FFT, DFT, Goertzel), digital filtering (FIR), sampling theory (up/down sampling), and time- and frequency-domain measurement techniques.
• Designing, implementing, and testing features in an existing, long-lived code base.

• Use of AI Development Tools such as Github CoPilot, Claude Code, Grok Code etc.
• Digital signal processing and data acquisition as applied to AC/DC Metering devices.
• Metrology fundamentals — accuracy, precision, resolution, and calibration — and familiarity with revenue-grade accuracy targets (e.g., 0.05% class).
• Experience implementing PQ recording features: waveform capture, high-speed RMS, harmonic logging, and PQDIF export.
• Knowledge of metering and substation communication protocols: DLMS, IEC 60870-5-102, IEC 61850, DNP 3.0, and Modbus (RTU/TCP).
• Familiarity with metering and power quality standards across regions — ANSI C12.20 (accuracy classes), C12.1 (code for electricity metering), C12.19 (end-device tables), and C12.18/C12.21/C12.22 (communications); IEC 62052/62053 metering; IEC 61000-4 EMC immunity series (4-2, 4-3, 4-4, 4-5, 4-6) IEEE C37.90.1; and the IEC 61000-4 EMC immunity series (4-2, 4-3, 4-4, 4-5, 4-6).
• Experience with relay test sets and power system simulators (e.g., Omicron, Doble).
• Familiarity with electrical wiring and safe handling of high voltage (up to 600 V).
• Demonstrated ability and willingness to use AI tools to improve productivity, decision-making, work quality, and to reduce costs. The successful candidate must be able to identify appropriate AI use cases and critically evaluate AI-generated outputs.

• Competitive compensation, holiday pay, and paid time off
• Great benefits package that includes health, vision, and dental insurance
• 401(k), plus matching
• Flexible spending accounts (FSAs), health savings account (HSA) with AMETEK contribution, life insurance, disability insurance, and family medical leave
• Paid parental leave
• Employee referral program
• Tuition reimbursement program
