About Diagonal J

Moving Recruitment in the Right Direction







Controls and automation engineering recruitment. Talent engine.

Our Company

Diagonal J Ltd is a specialist engineering recruitment agency for controls, automation and associated disciplines.

Our history in recruitment which has been focused solely on controls systems engineering gives Diagonal J a real edge over generalist agencies or even engineering specialists when it comes to truly understanding the skills and experience of engineers and managers within this niche.

Deploying across multiple sectors including water, energy, defense, pharma, food and beverage, manufacturing, FMCG and covering disciplines in electrical, mechanical, software, project engineering, and management, Diagonal J covers all aspects of controls and automation.

Based in Reading, Berkshire, we operate UK wide: From Plymouth to Aberdeen, from Inverness to London, through to Oxford, Bristol and Cardiff, back to Southampton and up to Nottingham, Liverpool and York, the whole of the UK is covered.



Our Philosophy

We recognise employees as the most important asset in any business and their innovation and skills are the key factors in driving any successful organisation. Moreover, instability and staff turnover result in reduced profitability and excessive costs. It is essential to embrace a practice that builds teams based on so much more than pure technical competence.

Our philosophy is not simply to match candidates to a job they are qualified and experienced to deliver. The personal fit is important too – this means they are aligned with their manager about their career path, they have joined a team environment and structure which fits their own way of working and they are suited to contribute to the company success and benefit from it.

This approach ensures that clients receive a service which provides real value in terms of time and money saved and ensures a cohesive team for long term success and stability.

Our Values

We’re Proactive

As well as covering the usual bases, we can offer that crucial bit more…

For clients, we access those candidates that conventional recruitment channels simply cannot reach. Through our own database and networks, we can approach high-quality professionals who are happily employed but would be open to an interesting opportunity that suits them well.

For candidates, we can offer a more bespoke representation with approaches to specifically targeted employers of choice and roles that reflect your personal objectives.

We search continuously to find the professionals who don’t typically use recruitment agencies or job boards. Our experience of the market, our focus on controls and automation and our relationships with individuals in the market means we are best placed to fill positions with the right people.


We’re Collaborative

For many recruitment agencies in the UK, filling a position is often a box ticking exercise. We take a different approach at Diagonal J, we work collaboratively with candidates and clients to make the right connection.

We will support the recruitment of successful candidates and the onboarding process to avoid the last minute complications that can otherwise all too often arise. We will add value to your business by providing you with people who will grow your business in the long term.


We’re Adaptive

Our processes are designed to make sure that we locate the highest calibre candidates and support applicants and clients throughout the whole process.

However, we are not constrained by a rigid company policy. Our approach to bespoke services means that we are happy to discuss tailoring aspects of the process according to client need.

Additionally, we can adapt our searches to suit the needs of the client to account for commercial, special technical or confidentially issues.

Likewise, for candidates we can meet the needs of a more discreet or specific representation where required.
