James Dónal Cronin

SharkNinja, Inc. · Needham, MA

• –Lead hardware and firmware development for early-stage consumer product concepts, taking ideas from sketch to working bench prototype to give leadership fast, data-backed go/no-go decisions.
• –Design and run electrical and thermal characterization, including multi-channel temperature and power logging and sensor response analysis, to define safety and performance margins.
• –Develop sensing and control prototypes for new smart-home product concepts, evaluating sensor options and embedded architectures.
• –Rapidly prototype on ESP32 and RP2040 (Raspberry Pi Pico) across thermal, time-of-flight, and gesture sensing to prove feasibility before formal development.
• –Build custom Python tooling to automate data conversion, visualization, and curve-fitting, shortening test-to-insight turnaround for the wider team.
• –Partner with industrial design, firmware, and test teams; advise colleagues on bench power-electronics safety practices.

Pison Technology Inc. · Boston, MA

• –Designed, tested, and integrated electrical systems and hardware modules for Pison's neural interface technology.
• –Developed and executed automated test protocols for hardware prototypes, including signal-integrity checks and debugging of electrical subsystems.
• –Performed real-time data acquisition and analysis of electrical signals during system bring-up and validation.
• –Applied statistical analysis to prototype datasets to uncover trends that informed design optimization and reliability improvements.
• –Collaborated with firmware, software, and product teams to resolve hardware issues and improve system performance.

Gilbane Building Company · Boston, MA

• –Supported management of the $80M HarbourVest project (256,000 SF, 11 floors), coordinating multi-disciplinary teams against tight schedules and budgets.
• –Worked with MEP consultants on electrical, mechanical, and plumbing designs; reviewed BIM models for clash detection across disciplines.
• –Conducted inspections for NEC and ASHRAE compliance, resolving non-conformances with design engineers and contractors.

Prochem Engineering Ltd · Kilkenny, Ireland

• –Delivered MV/LV electrical designs for pharmaceutical and manufacturing facilities using AutoCAD, Revit, and ETAP: schematics, single-line diagrams, and cable schedules.
• –Calculated electrical loads and short-circuit capacities to size transformers, switchgear, and circuit breakers; coordinated equipment procurement.
• –Designed lighting systems in DIALux to CIBSE standards and developed energy-efficient power distribution layouts.

Institute of Image-Guided Surgery (IHU) · Strasbourg, France

• –Built a fully functional out-of-scale GI tract prototype and its accompanying Android app for the FLUX project; tested and validated the design.
• –Explored sensor integration techniques and presented results to cross-functional teams, refining the design from feedback.
• –Helped draft an EU Call for Tender proposal to secure project funding.

Flextronics Ltd. · Cork, Ireland

• –Worked with engineers on production-line robotics; shadowed specialists in RF and PCB manufacturing and test.
