Data, Technology & Leadership Recruitment
We work with mission-led, cultural and heritage organisations, and selected greentech firms. On the roles that are hard to fill and costly to get wrong.
It starts with the right person
A role left open costs you. A role filled by the wrong person costs you more, and you do not always see it coming.
Xist4 finds the data, technology, AI and leadership people who can do the work, fit the environment and want to stay.
Get that right, and everything downstream gets easier.
Who we help
We work with organisations where specialist recruitment earns its place: mission-led, cultural and heritage organisations, selected greentech firms, and ambitious technology start-ups and scale-ups.
In mission-led, cultural and heritage organisations, we help teams hire the data, technology and leadership people they need to modernise, protect their systems and deliver what they are there to do. These are often small teams, working with real constraints, where one poor hire can carry a heavy cost.
In greentech, we work with companies electrifying transport, energy and the built environment. That includes public EV charging networks, smart charging and energy flexibility, battery technology and analytics, fleet electrification software, smart buildings and commercial IoT. These organisations sit where software, data, infrastructure, hardware and operations meet, and they need people who can build systems, improve platforms, make sense of complex data and lead teams through growth and change.
We also support ambitious technology start-ups and scale-ups building engineering, data and leadership teams. Less a sector than a kind of organisation: moving quickly, hiring carefully, and unable to afford a key hire going wrong.
The roles we recruit for
We recruit across leadership, software engineering, data science, AI and machine learning, data engineering and architecture, business intelligence, cyber security, cloud, infrastructure and specialist technical roles.
These are not easy roles to define, find or close. They build the platforms, protect the systems, turn data into decisions and hold the technology together.
In greentech, they may also sit close to infrastructure, hardware, operations and the physical systems behind electrification and connected environments.
Before we start a search, we take the time to understand your organisation, your team and what the role really needs to deliver.
Then we find the person who can do it.
Talent spotlight: Real people, real impact
Every week, we introduce a small selection of specialists we are currently speaking with across data, technology, cyber security, AI and leadership.
If someone looks relevant to a role you are hiring for, or a team you are building, get in touch and we will tell you more.

The Xist4 Candidate Journey Blueprint
Hiring rarely falls apart because there are no candidates. It falls apart because good candidates lose momentum, go quiet, or take another offer while the process drags.
The Blueprint is how we stop that. Every search has a clear structure, candidates who actually hear back, and a live feedback loop so you always know where things stand.
Sector expertise
We’ve built deep knowledge in the sectors where specialist recruitment earns its place.
Mission-Led, Cultural & Heritage Greentech Startups & Scale-ups
Ready to hire? Let’s talk.
If you need a recruitment partner to run the search properly, we can help. We manage the process from brief to offer, keeping candidates engaged and you informed the whole way.
Recruiting it yourself?
The Hiring Campaign Diagnostic is a two-day review of your brief, job description, salary, sourcing plan and candidate journey before you go fully to market.
It helps you spot the problems that could cost you weeks: the wrong salary, a weak advert, unclear role definition, poor sourcing routes or a process that good candidates will not wait around for.
£1,500, fixed. You get a straight written readout you can act on.
Our core specialisms
We specialise in the roles that shape strategy, turn data into decisions, protect critical systems and keep modern technology platforms running.
From senior leaders to hands-on specialists, we recruit across:
Infrastructure & Cloud Platforms
We recruit the cloud and infrastructure specialists who keep your systems running, your platforms secure and your organisation ready to scale. From cloud architects to DevOps engineers, these are the people modern digital businesses depend on.
Learn more
Senior Appointments
We find leaders who set direction, build high-performing teams and make hard decisions well. Whether you need a CTO, CISO, CDO or Director-level specialist, we look for people with the vision, capability and character to lead in complex, fast-moving environments.
Learn more
Cyber Security
We help you hire the specialists who protect your systems, your data and your reputation. From SOC analysts to information security leaders, we find people who take security seriously before something goes wrong.
Learn more
Data Engineering & Architecture
We connect you with data engineers and architects who design the pipelines, platforms and frameworks everything else relies on. Without them, data sits in silos. With the right ones, it flows where it needs to go.
Learn more
Data Science, AI & Machine Learning
We recruit data scientists, machine learning engineers and AI specialists who do more than run models. They ask the right questions, build production grade solutions and give organisations the capability to make better decisions and build smarter products.
Learn more
Business Intelligence & Insights
We recruit BI professionals who turn numbers into clarity. These are the people who help you understand what is working, what is not and where to focus next.

The people other recruiters passed over
Some of the best people I have placed had already been overlooked by everyone else.
The wrong background on paper. A gap that made people hesitate. A CV that did not quite sell what they could really do.
That is why we look past the obvious shortlist. We hire for what someone can actually do, how they think, and where they are heading, not only where they have been.
Get that right, and you build a stronger, more interesting team than the one the obvious search would have given you.
Principles
Good recruitment should leave more behind than a filled vacancy.
We work with organisations that care about decent work, fair pay, equal opportunity and long-term fit. In practice that means helping clients make better hiring decisions, treating candidates properly, and backing roles where people can do good work and build something that lasts.
Our approach is guided by UN SDG 8: decent work and economic growth. Fair, thoughtful recruitment that is actually useful, not the fastest CV in the inbox.
