Harry Pjetri

Passionate and aspiring engineer, keen to get hands on with projects and drive to completion. Primarily I am mechanically biased however I have varied experience spanning into electronics, control systems and structures. Designing, engineering and creating is not only a job for me but also carries into my hobbies. Excited to grow and contribute to the world we live in and a safer, more technologically advanced future.

Mechanical / Design Engineer at Atomic Weapons Establishment (AWE) (2024-12 – Present)

Design and develop process systems and safety-critical equipment within a regulated nuclear production environment.

• Develop conceptual and detailed mechanical designs for manufacturing systems using CAD and engineering analysis.
• Apply first-principles modelling and simulation to substantiate design decisions and optimise system performance.
• Develop and iterate production and containment equipment (e.g. furnaces, coating systems, cooling systems).
• Incorporate design-for-manufacture and design-for-reliability principles to enhance robustness and reduce downtime.
• Ensure design compliance with nuclear safety standards (e.g. ONR, DNSR), site licence conditions and ALARP principles.
• Produce rigorous technical justifications, supported by calculations and empirical data, to validate design suitability.
• Act as delegate for the Senior Engineer, contributing to design reviews and informed technical decision-making.
• Mentor graduates and apprentices, supporting their development in engineering standards, processes and best practice.
• Coordinate with multidisciplinary teams, managing activities through defined stage gates for efficient project delivery.

Mechanical Engineer at Transport for London (TfL) (2023-09 – 2024-12)

Supported mechanical design and implementation of critical data-centre HVAC, chilled-water and control systems.

• Assisted in producing and reviewing technical drawings, specifications, and performance calculations.
• Worked with senior engineers and multidisciplinary teams to deliver integrated engineering solutions.
• Took part in site inspections, installations, and commissioning, providing clear technical input.
• Followed strict health, safety, quality, and environmental standards in all engineering activities.

Engineering Internship at HGI Structures (2022-08 – 2023-09)

Supported structural design and analysis for residential extensions, refurbishments, and small commercial projects.

• Assisted in preparing drawings, calculations, and technical documentation under guidance from senior engineers.
• Conducted site visits and surveys to collect measurements and assess existing structural conditions.
• Contributed to the development of structural solutions using timber, steel, and reinforced concrete.
• Reviewed architectural plans to identify structural requirements and coordination issues.
• Supported the production of reports, sketches, and design notes for client and contractor use.
• Collaborated with engineers, architects, and contractors to support smooth project delivery.
