Job description

As a Technical Manager, you’ll be the technical authority for Renewable energy installations across your region. You’ll work closely with our subcontractor network and the office-based project management team to make sure every job is done safely, compliantly, and to a standard you’d be proud of.

Day to day, that means:

• Owning installation quality across your region — conducting remote reviews and on-site audits (both during and after installation) to maintain Sunsave’s standards
• Being the go-to technical voice — advising the wider Operations team on solar PV, battery storage, and EV charger installation best practice
• Onboarding new subcontractors — assessing capability, setting expectations, and helping new teams get up to speed as the network grows
• Problem-solving on live jobs — supporting installers and project managers when things don’t go to plan, and making sure customers aren’t left waiting
• Championing compliance — staying on top of building regulations, MCS standards, and Part P requirements, and making sure the business does too
• Travelling to site when needed — this isn’t a desk job, but it’s not full-time on the tools either. Expect a mix of site visits, remote work, and occasional trips to Sunsave’s London HQ for team events and planning

Where this can lead

This is a management role with real scope to grow. As Sunsave expands, there’s a clear path into senior operations leadership — whether that’s managing multiple regions, leading on technical compliance, or building efficient installation processes for new products. We’ll support you with management development so you can grow into the role and beyond it.

Knowledge, Skills & Experience

• Qualified electrician with at least 3 years’ hands-on experience in solar PV, battery, or EV charger installations
• 18th Edition IET Wiring Regulations (City & Guilds or equivalent)
• NVQ Level 3 in Electrical Installation
• ECS Gold Card
• Solid working knowledge of MCS regulations and installation best practice
• Good communicator who can work with subcontractors, customers, and office teams alike
• Full UK driving licence

Desirable (upskill training can be offered)

• Inspection and testing qualifications (City & Guilds 2391 or 2394/5 or equivalent)
• Experience managing or mentoring other installers or subcontractor teams

What we offer

The practical stuff:

• Competitive salary £40-50k + bonus
• Laptop and phone provided
• Equity
• Private health insurance and mental health support
• Monthly wellbeing benefits (via Juno)
• Enhanced maternity and paternity leave

Team & culture:

• Joining a close-knit team with a great culture
• Fortnightly company socials and quarterly team outings in London (travel expenses paid)

Our Values

We’re building something big in UK solar, and we want people who care about doing it properly. Three things matter most to us:

• Take pride in the work. We set high standards because our customers deserve it and because good work speaks for itself.
• Put the customer first. Every decision starts with what’s best for the homeowner. That’s how you build a reputation worth having.
• Back each other. We’re one team. We share what we know, give honest feedback, and don’t let egos get in the way.
