- Develop and manage retrofit-specific design strategies, including tie-ins to live systems, redundancy planning, outage and staging strategies, and resilience design.
- Conduct or oversee technical due diligence of existing data centre facilities, including capacity unlock assessments (power, cooling, and white space).
- Prepare and review detailed design drawings, schematics, schedules, technical reports, and tender documentation.
- Manage project scope, budget, programme, and contracts - identifying and mitigating scope creep, risks, and live-environment constraints.
- Liaise directly with clients (hyperscale, colocation, and enterprise operators), contractors, and vendors to ensure project goals are achieved with zero operational disruption.
- Drive quality assurance and governance across all assigned projects, adhering to WAP/PTW protocols in live environments.
- Mentor and support the development of junior engineers and graduate staff within the retrofit workstream.
- Support business development by contributing to proposals, client presentations, and technical strategies for retrofit opportunities across EMEA.
- Champion innovation in live-environment engineering and contribute to the continuous improvement of Ethos' retrofit delivery model.
- Lead electrical system tie-in strategies for live power distribution upgrades, including UPS changeovers, busbar modifications, and generator integration in operational environments.
- Bachelor's or Master's degree in Electrical Engineering or a related discipline.
- Minimum 8 years' experience in building services engineering, with at least 3 years focused on data centre or mission-critical projects.
- Demonstrable experience working in live, operational data centre environments - including brownfield upgrades, M&E replacements, or phased refurbishments.

- Proven expertise in electrical building services design for live data centre environments, including LV/MV power distribution, UPS systems, standby generation, busbar upgrades, and life safety systems.
- Experience delivering electrical upgrades within operational mission-critical facilities - including live switchgear replacements, UPS changeovers, and phased distribution upgrades.
- Strong working knowledge of AutoCAD, Revit MEP, Bluebeam, and Microsoft Office; experience with ETAP, Amtech, or DIALux for calculations.
- Excellent understanding of IEC, CIBSE, BS, IS, and EN standards applied to retrofit and live-environment projects.
- Experience producing single-line diagrams, schematics, and technical drawings for complex electrical retrofit scopes.
- Familiarity with commissioning, power system coordination studies, and compliance documentation for live data centre upgrades.
- Excellent communication and presentation skills, with confidence in client-facing settings.
- Strong organisational and problem-solving abilities, capable of managing multiple concurrent retrofit projects.
