Technical Trainer in City of London

Here at Complii, we are on the lookout for a Technical Trainer to play a key role in delivering impactful training across our growing organisation. This role focuses on building technical capability within our workforce, particularly within our fire division, while also supporting broader learning and development initiatives across the business. This is a primarily remote role, however, regular travel to sites will be required based on business needs. Some weeks you may be out on-site, while at other times there may be little to no travel.

You will play a critical role in shaping how training is delivered across Complii, ensuring learning is engaging, accessible, and aligned to business needs. From day one, the priority is delivering high‑quality training solutions, supporting employee development across both technical and non‑technical areas, and helping to build a strong culture of continuous improvement.

What you receive for joining us: We believe in rewarding expertise and accountability, which is why we offer a competitive salary. This includes 25 days holiday plus bank holidays, an additional day off for your birthday, a collaborative and supportive working environment, and the opportunity to work closely with senior leaders who value knowledge sharing, engagement, and continuous development.

Here is a look at some of the things you will be doing:

• Designing and delivering engaging training programmes across the business, covering both technical and non‑technical topics tailored to different learning styles and levels of experience.
• Facilitating training sessions through a mix of face‑to‑face, on‑site, and virtual formats to ensure accessibility and engagement.
• Working closely with stakeholders to identify learning needs and develop solutions that enhance both technical capability and overall employee performance.
• Supporting the development and maintenance of training content, ensuring materials are practical, relevant, and aligned with business and industry standards.

Can you show experience in some of these areas?

• Strong technical background within fire, water, or electrical disciplines, ideally combined with experience delivering or supporting training.
• Proven ability to design and deliver training programmes within a multiple stakeholder, business‑focused environment.
• Strong facilitation and presentation skills, with the ability to engage audiences at all levels and explain technical concepts clearly.
• A proactive, organised, and detail‑oriented approach, with the ability to manage multiple priorities and contribute to continuous improvement.

If you feel you have the skills and drive to make an impact, even if you don’t meet every requirement above, we’d still love to hear from you. You could be an experienced engineer looking to step away from the tools and move into a training role, with a passion for developing others, if so, get in touch.
