5 Things That Can Improve a Technical CV

A strong technical CV should make three things clear quickly: what you do, where you have done it and what difference your work made. Recruiters and hiring managers need enough technical detail to assess your suitability, but they also need a document that is easy to scan.

This is particularly important across engineering, power generation, nuclear, renewables, data centres and infrastructure. These sectors often recruit for specialist roles, so a generic CV can hide relevant experience that could otherwise help you secure an interview.

Here are five practical ways to improve a technical CV.

Start Your Technical CV With a Precise Professional Profile

Your opening profile should identify your discipline, level of experience, sectors and strongest technical areas.

Avoid introductions such as:

“I am a hardworking and motivated engineer looking for a new opportunity.”

This statement could describe almost anyone. Instead, make the first few lines specific:

“Electrical engineer with eight years’ experience supporting HV systems, commissioning and maintenance across utility-scale power and renewable energy projects. Experienced in contractor coordination, testing, technical documentation and safe delivery within regulated environments.”

The second example gives a recruiter useful search terms immediately:

• Electrical engineer
• HV systems
• Commissioning
• Maintenance
• Power projects
• Renewable energy
• Contractor coordination
• Testing
• Regulated environments

Your profile should be accurate and targeted to the role. Do not add technologies, certifications or responsibilities that you have not genuinely used.

Show Evidence, Not Just Responsibilities

A technical CV should explain what you achieved, not simply list your job description.

A weak bullet point might say:

“Responsible for maintenance of electrical equipment.”

A stronger version could say:

“Planned and coordinated preventative maintenance for electrical systems across an operational generation site, maintaining accurate records and escalating safety-critical defects through the site reporting process.”

The improved version describes the work, environment and level of responsibility without making an unsupported numerical claim.

Where you have legitimate figures, include them. Examples may include:

• Project value
• Team size
• Number of assets or sites supported
• Capacity of a plant or facility
• Duration of a programme
• Reduction in downtime
• Improvement in completion rate
• Number of contractors coordinated

Only use figures you can verify. If confidentiality prevents you from naming a client or project, describe the scale without revealing sensitive information. For example:

“Supported commissioning activities on a large UK infrastructure project, coordinating technical documentation, test records and contractor interfaces.”

This is more useful than simply writing “involved in commissioning.”

Put Relevant Technical Keywords in Context

Applicant tracking systems and recruiters often search for technical terms. However, a long list of keywords without evidence can make a CV look artificial.

Instead of placing every term in a disconnected skills section, show how you used it. For example:

“Produced and reviewed electrical testing documentation, supported commissioning activities and worked with contractors to resolve defects before handover.”

This provides context for terms such as electrical testing, commissioning, defect resolution, contractor management and handover.

Use the terminology that appears in the job description where it accurately reflects your experience. For engineering roles, relevant terms may include:

• AutoCAD or other design tools
• PLCs, SCADA or control systems
• HV and LV systems
• Planned and reactive maintenance
• Commissioning
• FAT and SAT
• RAMS
• Permit-to-work systems
• Root-cause analysis
• Asset integrity
• CDM or other relevant safety requirements
• Quality assurance and technical documentation

Do not keyword-stuff your CV. A recruiter should be able to understand it naturally.

Make Your Technical CV Easy to Read, Parse and Print

Your CV may be reviewed by both a recruiter and an Applicant Tracking System (ATS). These systems extract information from your CV to identify details such as job titles, employers, dates, skills and qualifications.

Keep your CV simple and text-focused so important information can be read accurately. Avoid putting key information inside images, graphics, text boxes or decorative elements. Complex layouts and multiple columns can also affect the order in which some systems read your CV.

A few simple rules can help:

• Use clear, standard section headings such as Professional Experience, Qualifications and Technical Skills
• Keep important information as selectable text rather than images
• Avoid photos, logos, charts, skill bars and unnecessary graphics
• Use a straightforward layout, with a single-column format being the safest option when you do not know which system will process your CV
• Avoid putting important information in headers, footers or text boxes
• Use standard fonts and clear formatting
• Check that you can select and copy the text from your finished PDF

Your CV does not need to look plain, but design should support readability rather than compete with the information.

The priority is making sure both people and recruitment systems can quickly understand your experience.

Remember that your CV may be viewed digitally or printed. Check that text remains clear and readable when printed, particularly if you have used lighter colours or greyscale text.

Make Qualifications, Certification and Eligibility Easy to Find

Technical recruitment often depends on specific qualifications, site access requirements or professional registrations. Do not make the reader search through several pages to find them.

Create a clear section covering relevant items such as:

• Degree, HNC, HND or apprenticeship
• Incorporated or Chartered Engineer status
• ECS, CSCS or other site cards
• CompEx, ATEX or hazardous-area experience
• IOSH, NEBOSH or relevant safety qualifications
• HV authorisation
• Welding, inspection or quality certifications
• Nuclear, defence or security-clearance eligibility
• Driving licence
• Right to work in the UK
• Willingness to travel or work away from home

Only include certifications that are current or clearly label those that have expired. If a certification is renewable, include the expiry date where appropriate.

Location and mobility are also important. A candidate may be technically suitable but unavailable for a site-based role. State whether you are based near the project, willing to relocate, available for regular travel, comfortable with site, shift or offshore work, and available for contract or permanent employment. This can remove uncertainty early in the process.

Tailor Your Technical CV to the Role

One CV rarely performs equally well for every engineering position. Tailoring does not mean rewriting your whole career history. It means prioritising the experience most relevant to the vacancy.

For a data-centre engineering role, you might emphasise critical environments, electrical or mechanical systems, UPS and standby generation, BMS or controls, planned maintenance, incident response, availability and resilience, and shift work.

For a renewable energy role, you might highlight wind, solar or battery storage projects, grid connection, electrical testing, construction or commissioning, O&M, asset management, contractor coordination and HSE performance.

For nuclear recruitment, relevant experience may include safety-critical systems, configuration control, quality assurance, regulated procedures, outage or maintenance work, nuclear baseline or site experience, security clearance, and ALARP or formal risk-management principles, where applicable.

The underlying lesson is simple: make the evidence relevant to the employer’s problem. Our guide to optimising your LinkedIn profile covers a similar principle for how recruiters find and assess you online.

If you are concerned about your current employer seeing changes to your profile, you do not need to publish every detail of your current role. Keep your profile accurate while focusing on your established skills, experience and previous achievements.

A Practical Technical CV Structure

A practical engineering CV might use this order:

1. Name and contact details
2. Technical profile
3. Core technical skills
4. Professional experience
5. Key projects
6. Qualifications and certifications
7. Professional memberships
8. Additional information, including location, travel and work eligibility

For most experienced engineers, two to four pages is usually enough to provide detail without becoming difficult to read. The correct length depends on your career history, project experience and seniority. Relevance matters more than an arbitrary page limit.

What Current Skills Demand Means for Your CV

The UK clean energy workforce is expected to require significant growth. Skills England and DESNZ project a 71% increase in employment across 31 clean energy priority occupations between 2025 and 2030. These occupations include electrical engineers, mechanical engineers, engineering technicians, project engineers, process engineers and engineering professionals (GOV.UK).

The same assessment identifies inspecting and testing structures and equipment, installing systems and equipment, and maintaining electrical and electronic equipment as leading technical skill areas across clean energy priority occupations. It also highlights the importance of numeracy, planning, adaptability, collaboration, problem-solving and digital literacy (GOV.UK).

This means your CV should not focus only on job titles. It should demonstrate the practical skills behind them. Our UK engineering skills shortage briefing and 2026 energy salary guide give more context on where that demand is concentrated.

The international picture is also relevant. The IEA reports that more than half of surveyed energy organisations face critical hiring bottlenecks, particularly in applied technical roles. Engineers with clear evidence of safety, quality, commissioning, maintenance, digital and project skills may therefore find opportunities across multiple countries and sectors (IEA).

Frequently Asked Questions

What should be included in an engineering CV?

Include a technical profile, relevant skills, employment history, project evidence, qualifications, certifications, professional memberships and practical information such as location, travel availability and right to work.

How long should a technical CV be?

There is no universal required length. It should be long enough to demonstrate relevant experience but concise enough to scan easily. Experienced engineers may need several pages, while early-career candidates can often provide sufficient detail in fewer pages.

Should I include every technology I have used?

Include technologies relevant to the role and explain how you used them. Avoid long, unsupported lists of software, systems or equipment.

Should achievements include numbers?

Yes, where the figures are accurate and can be disclosed. Verified figures can show scale and impact, but unsupported numbers should never be added simply to make a CV look stronger.

Is a cover letter still useful for engineering jobs?

A short, targeted cover letter can be useful when the role requires an explanation of motivation, relocation, sector transition, project relevance or transferable experience. It should add context rather than repeat the CV.

What is the most important improvement to make to a technical CV?

Make the first page clearly relevant to the target role. A recruiter should quickly understand your discipline, experience level, technical strengths, project environment and availability.
