We are a dedicated recruitment partner for smart buildings and commercial IoT — focused on the technology, data, AI and leadership talent that turns sensor and building data into lower energy use, fewer faults and better-used space. Xist4 runs specialist recruitment desks by sector, and this one does only smart-building technology and data.
The engineers who build a platform that pulls BACnet, Modbus and MQTT data from thousands of sensors, normalise it to a common model like Brick or Project Haystack, and run fault detection over it are scarce — and they rarely sit on a generic job board. Because this desk works only in smart buildings and IoT, through a software and data lens, we know where that talent sits. We take a clear, detailed brief and screen hard against it, so you see people who match what you actually need, not whoever has the right words on a CV.
We recruit the disciplines we know best, applied to the built environment — from the edge gateway up to the analytics and leadership layer that sits above your building systems.
Backend and platform engineers building the cloud platforms that ingest BACnet, Modbus and MQTT telemetry from across a building or portfolio and turn it into something applications can use.
Data engineers and architects building the time-series pipelines and stores that move sensor data at scale and normalise it to a common model like Brick or Project Haystack.
Data scientists and ML engineers building the fault detection, anomaly and predictive-maintenance models — and the occupancy and energy forecasting — that turn building data into decisions.
Embedded and edge software engineers writing the firmware and on-gateway logic that collects, normalises and processes sensor data close to the building before it reaches the cloud.
Cloud, DevOps and SRE engineers who keep connected-building platforms reliable, and security engineers who protect those platforms and the building data they hold.
CTOs, CDOs and VP/Head of Engineering, Data and Product who set the roadmap and build the teams behind smart-building and IoT products.
We recruit using the titles the smart-building and IoT market actually uses. The specialism comes from the domain, not a bolt-on label.
They understood our building-data platform better than the generalist agencies we had tried for years. The shortlist was small, relevant and fast.
Straight, honest conversations from the first call. They put me forward for roles that actually fit, not just whatever was open.
We built our first building-analytics data team with their help. They got the hiring order right and kept every candidate engaged.

Whether you need to fill a hard software, data or IoT vacancy, or want to sharpen your brief before going to market, we can help.
We work with PropTech and smart-building software companies, IoT platform vendors, and the property and facilities businesses building their own teams — filling the software, data and leadership roles that decide whether a product ships.
Smart-building software is a small, fast-moving world. The best platform, data and ML engineers are rarely on job boards, and a generalist agency working ten sectors at once does not know who they are. Because this desk does nothing but smart-building and IoT software, we already know the market and the people in it — and we screen every shortlist hard against a clear brief before it reaches you.
Years building relationships with smart-building and IoT software, data and platform professionals in the UK means we reach passive talent quickly. Our EU and US networks are smaller but growing — both are markets we are actively building into.
We take a clear, detailed brief, then screen hard against it — competency-led questions, more than one pass, and a strong sense of what good looks like for the role. You meet people who match what you actually asked for, not a CV with the right words on it.
No competing briefs and no noise. Every conversation on this desk is a smart-building software conversation, which keeps our knowledge and shortlist current.
A structured search with consistent communication and a live feedback loop, so strong candidates stay engaged and offers do not fall apart.

Tell us about the brief and we will tell you exactly how we would find them.
If you build data platforms, write edge firmware, train models or lead teams in the smart-building and IoT world, we will help you find the right move — not just the next one.
We work across the smart-building software and data stack, from hands-on specialists to technical leadership. Typical roles include:
Honest conversations, a genuine grasp of the roles and the market, and no spray-and-pray. We only put you forward for roles that fit your skills and what you actually want next, and we keep you informed at every stage.
If you are looking for your next mid, senior or leadership-level move and want to work with forward thinking businesses please get in touch.
A clear, structured search that keeps scarce smart-building specialists engaged and clients informed from brief to offer.
We learn your platform, roadmap and team before we approach a single specialist.
We tap a deep, smart-building and IoT network — not job boards — and engage people who genuinely fit.
We screen rigorously against the brief — competency-led questions, more than one pass — so you meet people who match what you asked for.
We manage offer, notice and onboarding so your hire fits and stays from day one.
"If you want to go fast, go alone. If you want to go far, go together."

Whether you are hiring or looking for your next role, we would love to hear from you.
Before a role goes live, or after it has stalled, find out whether your hiring campaign is actually set up to work.
It is a standalone product. You are not buying a search. You are buying the work a good agency does before it runs one — your brief, your salary, your advert, your sourcing and your candidate journey, taken apart and handed back to you as a report you can act on yourself. Everything an agency does to get a role filled, without handing the role to one. Built on 26 years of specialist recruitment.
People use it for two reasons. The first is before a role goes live, to find the problems while they are still cheap to fix. The second is when a campaign is already running and not working — four weeks in, nothing decent through the door, and no clear reason why. At that point you have something genuinely useful: live data. Real response rates, real drop-off, real feedback. More often than not, that data makes the problem easier to pin down.
For context: a campaign that runs eight to twelve weeks and turns up nobody worth hiring rarely costs less than £15,000 in management time, advertising and lost productivity — before you count the role sitting empty. The Diagnostic is £1,500, and there is no obligation to use Xist4 for the search itself.
Ten areas that decide whether a campaign works, each rated red, amber or green, with market data and specific fixes. No vague feedback. You see what to fix, what to leave alone, and what is quietly costing you the hire.
Where and how to advertise the role, in what order, and how to keep it visible past day one instead of peaking on the first morning and fading.
Specific actions for your role and your market that you can act on this week. Built around the job in front of you, not lifted from a checklist.
We walk you through the findings, answer your questions and agree next steps, so you leave with a plan rather than a document to file.
Tell us the role and where the campaign is up to. We will send the full Diagnostic breakdown and answer any questions — no obligation to use Xist4 for the search.
We are a focused recruitment partner for the smart-building and commercial IoT world, connecting employers with the software, data and leadership talent behind intelligent, well-run buildings.
This is Xist4's dedicated smart-building desk — building-data platforms, IoT and analytics software, and the data and leadership layer around them. It is a deliberately narrow practice, and that focus is what lets us understand the sector, know the market, and reach specialists a generalist agency cannot.
Good hiring is not about filling a seat. It is about finding someone who raises the bar, fits the team and stays. We take a human, structured approach to every search and treat candidates and clients with the same honesty.
Smart-building and IoT software is all this desk recruits in, through a software, data and leadership lens.
A clear, detailed brief and competency-led screening, done thoroughly. We know the sector and the market, so we know what good looks like for the role.
Clear communication, fair process and no spray-and-pray. People first, always.
A deep UK network in smart-building and IoT software, built over years rather than bought from a database. Our EU and US networks are smaller but growing, as we build into both.
