Job Title: Senior Electrical Engineer

Salary: From £60k (depending on experience)

Location: Washington, UK (NE37 3HB)

Overview

Enspec is scaling up its manufacturing capability, and this role sits right at the centre of that growth. We’re looking for a Senior Electrical Engineer who brings strong technical knowledge together with practical, hands-on manufacturing experience. You will take ownership of delivering high-quality engineered products, harmonic filters, PFC equipment, and other power-quality systems, through precise design work, solid manufacturing documentation, rigorous testing, and effective root-cause investigation.

You’ll serve as a technical point of reference within our manufacturing operations, making sure our products meet IEC/BSI standards, align with grid code requirements, and are manufactured safely, reliably, and to specification. You will also contribute to on-site surveys that feed accurate data into the design process, gradually picking up responsibilities currently handled by more junior engineers as the team grows.

The role calls for initiative, high technical standards, and the ability to connect design thinking with practical manufacturing and testing realities.

The Role

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, switchgear 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).

Collaboration, Mentorship & Cross-Team Work

• 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 management skills with experience leading technical projects to successful completion.
• High level of attention to detail and commitment to quality.
• Excellent written and verbal communication skills, particularly in technical documentation.
• Ability to work independently and as part of a collaborative technical team.

Preferences

• Proficiency with electrical CAD/design tools (e.g., AutoCAD Electrical, EPLAN, or similar).
• Experience in the design of reactive power compensation and power quality systems from 11 kV to 400 kV, including harmonic filters and associated equipment.
• Demonstrated ability to mentor and develop junior engineering talent.
• Commitment to continuous learning and staying updated with the latest advancements in electrical engineering.

Benefits

• Competitive salary based on experience.
• Flexible working hours and a supportive work environment.
• Opportunities for career growth and advancement within a dynamic and growing company.
• Training and development opportunities to enhance your skills and knowledge.
• 24 days of holidays plus bank holidays.

At Enspec, we believe every employee is critical to our success. We prize good people, ambition, and hard work. We offer a range of flexible employee benefits along with career development opportunities.
