A family-owned technology firm in Lisburn, Northern Ireland, that makes sensors, software and services for electricity networks and railways.
Camlin Group makes monitoring technology for the electricity grid and the railways. Its hardware sensors are fitted to transformers, overhead power lines, low-voltage supply points, trains, overhead rail wires and signalling power equipment, and its software turns the readings into warnings, so that operators can find faults early and plan maintenance rather than waiting for something to break. Products include TOTUS for transformers, LineSIGHT for locating faults on overhead lines, PRESense for low-voltage networks and the Sapient data platform on the energy side, and PanVue, RoofVue, CatVue, CarVue and the Theia analytics platform on the rail side.
The company has two main parts, Camlin Energy and Camlin Rail. It says its mission is to help operators modernise their networks, prevent power cuts, improve safety and support the shift to cleaner energy, electrification and a more resilient grid. Camlin was founded in 2008 by Co Tyrone industrialist John Cunningham and is run by his sons, Peter as chief executive and Michael as chief operating officer. It is described in the press as family-owned.
Camlin is headquartered at Ferguson Drive in Lisburn, Northern Ireland, and a trade report puts its workforce at around 650 people. The company also operates in Great Britain, Europe, North America, Australia and Asia, with North American offices in the Atlanta and Chicago areas. Its customers include UK utilities and US rail operators such as Amtrak, SEPTA and Caltrain. In June 2026 Siemens Energy announced an agreement to acquire Camlin, expected to complete before the end of 2026 subject to approvals, and the chief executive said customers should expect business as usual with the leadership team staying in place.
The company was named in the Sunday Times 100 Tech 2026 ranking of the UK's fastest-growing private technology companies, which is based on three years of sales growth. Camlin's own pages do not describe its culture or values in detail, so we do not make claims about them here. What the public material does show is a firm that designs, develops and manufactures its own monitoring equipment as well as writing the analytics software, so electronics engineers, software teams and field engineers work in the same business. Its stated aim of preventing outages and supporting decarbonisation gives the work a clear purpose.
A company like this employs electronics and hardware engineers, embedded software developers, data scientists and AI specialists, cloud and platform engineers, manufacturing and test technicians, project engineers who install and commission systems on utility and rail sites, and sales, customer support and finance teams. It has a presence in both energy and rail, so there are varied sectors to learn about. People who are interested in how electricity and trains actually work, and in technology that keeps them running, will find plenty to explore.
