Lucy Willis

MECHANICAL ENGINEER

Skills Overview

Lucy is an experienced mechanical design engineer with a strong background in delivering complex products across consumer appliances, medical devices, and electromechanical systems. She brings end-to-end design capability, from early concept development through to detailed design, analysis, and validation. Methodical and self-motivated, Lucy combines her strong technical understanding with clear communication, working effectively both independently and within multidisciplinary teams.

PRODUCT DEVELOPMENT & MECHANICAL DESIGN – Lucy has a strong foundation in mechanical systems and is able to derive designs from engineering first principles, calculations, and engineering standards. She is confident working from early concept development and prototyping, through to production-ready components.
ENGINEERING SOFTWARE & DOCUMENTATION – Lucy is highly experienced in creating 3D models, technical drawings, and managing engineering BOMs. She is proficient in Siemens NX, SolidWorks, and PTC Creo,and several PDM, ERP, and CRM software packages. She brings expertise in drafting standards, including GD&T, with formal training in BS 8888 and ISO GPS standards
PRODUCTION & MANUFACTURING ENVIRONMENTS – Lucy has a strong intuitive understanding of design for manufacture (DFM) and design for assembly (DFA). She is highly experienced designing components for machining, injection moulding, sheet metal fabrication, and complex welded assemblies. She thrives working hands-on in workshop environments, helping to bridge the gap between analysis, design intent, and real-world manufacture.
ENGINEERING STANDARDS & REGULATIONS – Lucy has extensive experience working in highly regulated environments. She is comfortable navigating engineering standards, risk management, and verification and validation processes, and has hands-on experience producing the documentation required to support compliant, production-ready designs.

PERSONAL STATEMENT

I’ve always loved solving puzzles, which makes engineering a perfect fit for me. Having a career that allows me to do that every day has been incredibly rewarding. I’ve developed the skills to turn ideas into real products, build things that improve people’s lives, and develop technology that makes a real difference.

Outside of work, I enjoy getting outdoors through tramping and trail biking. I bring the same curiosity and determination from these hobbies into my work and am excited to keep growing as an engineer.

Project Experience

SIEMENS HEALTHINEERS

Magnet Dry Technology

Led the cryogenic system design for superconducting MRI magnets as part of the development of DryCool technology, reducing helium volume requirements while maintaining superconducting temperatures (–269 °C). Responsible for end-to-end system design, ensuring compliance with technical requirements and project schedules, and overseeing other design engineers. Contributed across the full product development lifecycle, from requirements definition to detailed manufacturing documentation. Produced and maintained 3D models and engineering drawings using Siemens NX and Teamcenter, managed engineering BOMs, and refined designs based on thermal and structural analyses to ensure performance.

Fisher & Paykel Healthcare Breathing Set

FISHER & PAYKELL HEALTHCARE

Breathing Circuit Design

Led the design, development, and validation of disposable and reusable breathing circuit sets for respiratory humidifiers within a regulated medical device development programme. Delivered end-to-end design and manufacture of plastic injection-moulded components, including part and tooling design, hands-on CNC machining, and in-house moulding to support rapid prototyping and validation. Worked extensively within international medical device standards, supported by comprehensive verification, validation, and statistical analysis. Contributed to the product release process, including the successful completion of a 510(k) submission for US market approval.

Fisher & Paykel Appliances Belt Drive Motor

FISHER & PAYKELL TECHNOLOGIES

Belt Drive Cost Down Project

Mechanical design engineer on a value engineering project for a belt-driven BLDC motor, focused on improving cost efficiency while maintaining performance and reliability. Responsibilities included performing structural (FEA) analysis on proposed design changes to validate mechanical integrity, conducting risk assessments and developing design verification plans (DVPs). The project required close communication with magnetics specialists and China-based manufacturing engineers to ensure successful implementation.

Rangehood ‘Clean Air’ Project

Mechanical development of an innovative range hood aimed at redefining how customers achieve a fully “clean” kitchen environment. Core responsibilities included the design and fabrication of test rigs and prototypes, development of structured test plans using design of experiments (DOE), and detailed analysis of results. The project required regular technical communication with the China-based parent company, including three project visits to Qingdao, to support collaboration, testing, and product development.
