Senior Research Engineer, Structural Dynamics & Vibrations

Gridware • San Francisco, CA

10d • Onsite

About The Position

Gridware is a San Francisco-based technology company dedicated to protecting and enhancing the electrical grid. We pioneered a groundbreaking new class of grid management called active grid response (AGR), focused on monitoring the electrical, physical, and environmental aspects of the grid that affect reliability and safety. Gridware’s advanced Active Grid Response platform uses high-precision sensors to detect potential issues early, enabling proactive maintenance and fault mitigation. This comprehensive approach helps improve safety, reduce outages, and ensure the grid operates efficiently. The company is backed by climate-tech and Silicon Valley investors.

We are seeking a creative, hands-on Senior Mechanical Research Engineer with significant vibration and dynamics experience to lead complex mechanical sensing problems on edge grid intelligence products with real-world impact.
You will become an expert in how our grid sensor signals — accelerometer, IMU, and other mechanical-measurement signals — behave in the real world across diverse infrastructure. You will investigate sensing performance via exploratory data analysis, dynamics modeling coupled with bench and full-scale testing. You will also support design improvements, and validate improvements using test infrastructure you develop. You will define mechanical sensing requirements, develop measurement-chain improvements, and help mature new mechanical sensing capabilities.
The focus is on understanding the mechanical phenomena that affect the grid, including measurement performance, validation, and technology transfer, rather than product design or implementation.

Requirements

• Senior-level experience: PhD in Mechanical Engineering, Aerospace Engineering, Engineering Mechanics, or a closely related field plus 3+ years of relevant industry experience or MS in one of those fields plus 6+ years of relevant industry experience in owning open-ended, research-driven mechanical sensing or signal-quality problems.
• Strong fundamentals in vibrations, dynamics, and structural response, with the ability to connect those fundamentals to real signals — extracting physical meaning through modal analysis, impact identification, source separation, frequency-domain feature extraction, and transient classification.
• Track record of owning ambiguous sensing, signal-quality, or measurement-performance problems from characterizing through validation.
• Scientific computing: comfortable writing analysis pipelines in Python, MATLAB, or equivalent to investigate and report system performance to broad audiences.
• Experience collecting high-quality mechanical measurements: have built and run custom measurement setups using accelerometers, IMUs, force/strain transducers, and standard lab instrumentation (DAQ and related tools).
• Strong technical judgment, communication, and cross-functional collaboration.
• Experience leading technically complex work with multiple stakeholders and deadlines.

Nice To Haves

• Experience with deployed IoT fleets (tens of thousands of devices) and developing observability for long-term sensor performance — telemetry design, health metrics, calibration drift monitoring.
• Experience designing system validation plans with explicit acceptance criteria and building or owning repeatable test infrastructure.
• Embedded DSP exposure — applying DSP to real sensor signals on resource-constrained devices.
• Experience optimizing sampling and signal processing on constrained compute devices to reduce power and storage.
• Experience in sensor coexistence testing.

Responsibilities

• Develop mechanical sensing performance requirements. Select and evaluate new sensors for current and new mechanical sensing capabilities.
• Root-cause mechanical sensor signal issues from fleet to bench: use fleet telemetry (time-series + metadata) to isolate failure patterns, modes and signatures, test hypotheses via dynamics modeling and benchtop reproduction, contribute to design solutions, and partner with HW, FW, and SW engineering to implement them.
• Characterize and validate how diverse infrastructure types — different pole materials, geometries, and equipment configurations — affect mechanical signal behavior. Translate findings into design guidance, device installation requirements, monitoring and data aggregation methods.
• Develop and own test methods to characterize and validate mechanical sensor performance across diverse and variable operating conditions.
• Develop hardware-in-the-loop test infrastructure to reproduce real-world mechanical phenomena Gridware technology detects. Run hardware-in-the-loop tests to validate changes to our tech stack (from phenomena → hardware → automation → customer).
• Develop signal quality observability for mechanical sensors: sensor trust metrics, quality scoring, and gating criteria for downstream uses of data.
• Mentor team members. Raise the technical rigor of experiments, analysis, and validation work across the team.
• Collaborate closely with product managers, data scientists, automation engineers, SW/HW/FW engineers, as well as non-technical teams such as customer success, field teams, and manufacturing.

Benefits

• Health, Dental & Vision (Gold and Platinum with some providers plans fully covered)
• Paid parental leave
• Alternating day off (every other Monday)
• “Off the Grid”, a two week per year paid break for all employees.
• Commuter allowance
• Company-paid training
