Experience

Associate AIV and Flight Software Engineer

ClearSpace | September 2025 – Present

Working within AIV/Software to develop hardware emulators, FlatSats and flight software.

AIV Simulation Intern

ClearSpace | April 2025 – September 2025 (6 months)

Working to facilitate closed loop HIL testing and supporting the development of closed loop flight software validation facility.

BEXUS 37 - Project SOBER Payload & Mechanical Co-Lead

REXUS/BEXUS Programme | September 2024 – December 2025 (1 year 4 months)

As the Payload and Mechanical Engineering Co-Lead, I oversaw a team of five members to complete the mechanical design of a stratospheric balloon payload. This involved not only technical work but also rigorous systems engineering documentation, regular design reviews, and interactions with our industry stakeholders. The programme is supported by experts from ESA, DLR, SSC, Rymdstyrelsen, ZARM and EuroLaunch. BEXUS 37 launched successfully in October 2025 from Esrange Space Center in north Sweden with the longest flight time ever recorded as part of the BEXUS programme.

AOCS Team Lead

QMSEDS | October 2024 – July 2025 (10 months)

I served as the Attitude and Orbital Control System (AOCS) Lead for QMSEDS during the 2024/25 UKSEDS Satellite Design Competition, run in partnership with Airbus and Skyrora. Our team successfully designed, integrated, and presented a 3U CubeSat focused on rendezvous and proximity operations. I led the AOCS subsystem from preliminary analysis through to final integration and testing, guiding the team through the Critical Design Review (CDR) - where we scored 10/10 - and contributing to the overall success of the project, which was awarded Best Presentation for its systems engineering traceability and cross-team collaboration.
