CNC Machinist
"passionate about driving innovation and efficiency on the factory floor"
Please tell us about your experience in the aerospace field
I’m currently working as a CNC Machinist at Safran, specialising in 5‑axis milling and precision manufacturing. My work combines hands-on machining with a strong academic foundation, enabling me to translate complex engineering principles into real-world results. I’m passionate about driving innovation and efficiency on the factory floor, especially through integrating Lean and sustainable manufacturing practices. Whether it’s reducing energy consumption, minimising material waste, or optimising toolpath strategies, I’m committed to continuous improvement and eco-conscious engineering. With previous experience working at Dyson, Broadway Engineering, and Safran, I’ve built great knowledge of the aerospace industry as a whole.
Could you share how you became interested in pursuing aerospace
Aerospace was never my main interest, manufacturing engineering is/was. The engineering sector is huge, and most of the precision work I look for is in aerospace and automotive/motorsport. The use of exotic materials, rapidly emerging technologies, and advancements in manufacturing capabilities, make these sectors great places to be. There’s always something new to learn, and there’s always something around the corner to get involved with next.
My site provides resources for high schoolers interested in aerospace and aviation. What advice would you give them?
Take in as much as you can. There’s some great knowledge in this area. With technology advancing at a rapid rate, the only way to get a full understanding of the processes and constraints in this industry is to listen. Experienced engineers are your best friends, and are always happy to help. We’re very much a supportive industry and will always promote young engineers to learn and develop.
Could you tell us about any challenges or surprises you’ve encountered—perhaps something that turned out differently than expected?
Nothing happens right first time, and nobody is expecting it to. Whether it be an idea, a physical process, or anything else, if it goes wrong, don’t dwell. Learn from mistakes and use them as the foundation for building your knowledge and skillset. The best engineers aren’t the ones that get everything right, they’re the ones that have the ability to identify a root cause issue and set out clear intentions/steps to rectify and eliminate them.
Please share a fun fact
A Boeing 747 has over 6 million parts. Including more than 170 miles of wiring and 5 miles of tubing.
