Senior Electrical Engineer

Overview

Enspec is evolving its manufacturing capability, and this role sits at the heart of that shift. We are looking for a Senior Electrical Engineer who combines deep technical expertise with hands-on manufacturing experience. You will lead the delivery of high-quality engineered products—harmonic filters, PFC equipment, and wider power-quality systems—through accurate design, robust manufacturing packs, thorough testing, and strong root-cause analysis.

You’ll act as a technical authority within our manufacturing environment, ensuring our products meet IEC/BSI standards, comply with grid codes, and are built reliably, safely, and to spec. You will also support onsite surveys to inform accurate design data, taking a share of the responsibilities currently held by junior engineers as the team develops.

This role requires initiative, high technical standards, and the ability to bridge design with real-world manufacturing and testing.

Manufacturing Delivery & Engineering Support

• Produce complete, accurate, and manufacturable engineering packs—including schematics, BOMs, wiring diagrams, layouts, build instructions, and test plans.
• Provide real-time technical support to the manufacturing team during assembly, wiring, build, and FAT.
• Lead fault diagnostics and root-cause analysis for manufacturing issues, field returns, or test failures.
• Own engineering change control and ensure updates flow efficiently into manufacturing documentation.
• Coordinate and lead factory acceptance testing (FAT), including test documentation, witness testing and compliance checks.
• Ensure all manufactured systems meet IEC, BSI and other relevant UK and international standards.

Design & Technical Leadership

• Lead the design and development of advanced electrical systems such as harmonic filters, power factor correction systems, switch gear interfaces and LV/HV assemblies.
• Validate designs through calculation, simulation, or modelling as appropriate.
• Drive continuous improvement in manufacturability, product quality, and design consistency.

Technical Standards & Compliance

• Maintain working knowledge of IEC/BSI standards for design, manufacturing, testing, and safety.
• Ensure all designs and manufactured items comply with internal quality procedures and external certification requirements (ISO, grid codes, client specifications).
• Support documentation and risk assessments relating to electrical safety, test procedures, and compliance.

Site Surveys & Client Interface

• Conduct electrical site surveys to capture measurements, installation constraints, and integration requirements.
• Prepare clear survey reports to feed into accurate design and manufacturing planning.
• Support pre-installation and post-installation technical queries.

Testing, Validation & Quality Assurance

• Lead end-to-end testing and validation of products—including insulation testing, functional testing, continuity checks, harmonic filter tuning checks, etc.
• Develop test rigs, procedures, and commissioning documentation to support consistent product validation.
• Identify failure modes and implement corrective and preventive actions (CAPA).
• Work closely with manufacturing, engineering, procurement, and project teams to ensure smooth product delivery.
• Provide technical mentorship to junior engineers and technicians, helping them build diagnostic and manufacturing-readiness skills.
• Support cross-functional initiatives to improve quality, reduce build time, and strengthen standardisation.

Qualifications and Requirements

• Bachelor’s degree in Electrical Engineering or a related field; a Master’s or higher is preferred.
• Significant hands-on experience in electrical engineering, with a focus on design and development of electrical systems.
• Extensive experience in the renewable energy sector and related industries.
• Deep understanding of electrical standards and regulations, both national and international.
• Proven track record of technical innovation and practical application in electrical engineering.
• Proficient in using advanced electrical engineering software and tools for design and analysis.
• Excellent problem-solving skills with the ability to tackle complex technical challenges.
• Strong project…
