Graduate Engineer

I’m currently a graduate engineer doing my placement in the Systems & Test function and working on high-speed flight. I’m still learning in my placement and every time something “clicks” it feels like an achievement. Recently, I got to co-host a bake-off with a colleague, and it turned out to be a blast which I’m pretty happy about!

Back in university, cycling was my jam for both wellness and convenience. After asking around at work, I found out how the cycle2work scheme works and within a week of finding a bike I liked, my application was approved. Being able to buy accessories with the scheme was quite convenient as well!

Cycling gives me my daily cardio and with Oxford’s traffic spiking by 8.2% in 2022, cycling feels like the eco-friendly way to go.”

“I am a Graduate Engineer at Reaction Engines, currently in my final year of the graduate scheme. Having lived abroad for many years, I have realised how enriching it is to meet people with different cultures, backgrounds, and stories, and how fundamental being exposed to all of this was for my personal growth.

I am passionate about ED&I because I believe sharing and embracing differences will make us better individuals, both on a personal and professional level. This is why I recently joined the amazing ED&I team we have at Reaction Engines as part of the ED&I Newsletter editorial team. Having the opportunity to contribute to such an important piece of work is invaluable for me. Seeing how engaged people are, and how open they are to sharing their stories, makes me incredibly proud of being part of this community.”
