How to Write a Low Voltage Engineer Resume (2026 Guide With Examples)

A low voltage engineer resume that just says "responsible for low voltage" gets filtered out. When recruiters screen low voltage engineers, they look for one thing: can you design and integrate ELV systems that work together and build. A resume that wins interviews speaks in systems, design, and integration results. Here is how to write it.

What a low voltage engineer must prove

• ELV systems: security (CCTV/access/alarm), building automation, network, structured cabling, AV.
• Design: system design, device count, topology, selection, drawings.
• Integration: system integration, head-end, interfaces, platform, protocols.
• Delivery: installation, commissioning, testing, handover, support.

In one line: your resume should answer "what ELV systems did you design, how was the device count and topology, did integration work, and did it commission."

Don't just list duties, show systems and integration

Use concrete outcomes and quantify them:

• ❌ "Responsible for low voltage" — shows nothing.
• ✅ "Designed ELV systems — CCTV/access, structured cabling, and building automation — with device counts and topology, integrated to a head-end and platform over protocols, and commissioned with testing and handover" — systems, design, integration, and delivery.

Things you can quantify: projects / systems / devices, CCTV / access / cabling, integration / head-end / protocols, commissioning / testing / handover. For methods, see how to quantify resume achievements.

How to write the skills section

Group your low voltage skills so a reviewer can scan them:

• ELV systems: security (CCTV/access/alarm), building automation, network, structured cabling, AV, PA
• Design: system design, device count, topology, selection, drawings, standards
• Integration: system integration, head-end, interfaces, platform, protocols
• Delivery: installation, commissioning, testing, handover, support
• Tools: CAD, network, integration, testing

For structure, see how to list skills on a resume.

Low voltage engineer vs building electrical engineer

These roles work together but differ, so make your focus clear:

• Low voltage engineer: owns the ELV/systems — security, automation, cabling, and integration.
• Building electrical engineer: see how to write a building electrical engineer resume, owns the power services — distribution, lighting, and protection.

If you do both, say so, but lead with the systems and integration depth. Related role: how to write a building services engineer resume. Related role: electrical engineer. Tailor to the target with how to tailor your resume to a job description.

Common mistakes

• "Responsible for low voltage" with no data: no system, design, or integration detail.
• No systems: security, cabling, and automation are the core ELV scope — surface them.
• No integration: head-end, platform, and protocols show your integration ability.
• No delivery: commissioning, testing, and handover show your work builds.
• Vague claims: "strong ELV experience" loses to "designed CCTV/access and cabling, device counts and topology, integrated to a platform, commissioned and handed over."

Frequently Asked Questions

What should a low voltage engineer resume highlight?

Highlight ELV systems, design, integration, and delivery. Use projects/systems/devices, CCTV/access/cabling, integration/head-end/protocols, and commissioning/testing/handover data to prove what ELV systems you designed, how the device count and topology were, whether integration worked, and whether it commissioned — not just "responsible for low voltage."

How do I quantify a low voltage engineer resume?

Use system and integration metrics: the projects and devices, CCTV, access, and cabling, integration, head-end, and protocols, and commissioning and handover. For example, "designed CCTV/access and structured cabling with device counts and topology, integrated to a head-end and platform, commissioned with testing and handover" says far more than "responsible for low voltage."

Should a low voltage engineer resume mention integration?

Yes — integration is the core value of ELV. Multiple systems must work together through a head-end and platform, so whether you can design systems and integrate them is exactly what recruiters want to see. Put your systems, design, and integration work together, and describe outcomes honestly. An engineer who can design ELV systems, integrate them, and commission is worth far more than one who just "did low voltage" — so make the systems, design, and integration concrete.

How is a low voltage engineer resume different from a building electrical engineer's?

A low voltage engineer owns ELV/systems — security, automation, cabling, and integration; a building electrical engineer owns power services — distribution, lighting, and protection. A low voltage resume should emphasize ELV systems, integration, and commissioning, while a building electrical resume leans toward power distribution and lighting. Different focus — tailor to the target role.

The core of a low voltage engineer resume is proving you can design and integrate ELV systems that work together and build. Speak in systems, devices, integration, protocols, and commissioning data, lead with results, and your resume will compete.
