The sector is growing, and that growth shows up in the number of people it employs. MOD expenditure with industry supported a total of 272,000 direct jobs in 2023/24, an increase of 11% compared to the previous financial year, according to the MOD's supported employment estimates for 2023/24. That builds on the year before, when the total number of MOD-supported UK jobs reached 239,000 in 2022/23, an increase of 6% on the previous financial year the MOD's 2022/23 estimates.
Fresh investment keeps adding demand. More than 1,700 new jobs are being created across the UK defence sector following at least £1.4 billion in foreign direct investment committed since July 2024 a 2025 GOV.UK announcement. And the sector has pulled hard on talent for a while now: surveyed recruitment grew by 17.8% in 2022 a 2024 GOV.UK release on the defence sector. For a specialist role like human factors, that means you're competing for a small pool of people in a market that keeps expanding.
Human factors sits between engineering, psychology and safety. The person reduces the chance of human error by shaping how someone uses a system: a cockpit display, a control room, a maintenance process, a piece of protective equipment. When a role is new, nobody inside the organisation has done it before, so there's no existing job description to copy and no clear picture of where the person sits.
That matters because the sector is still growing fast, and the supported workforce has risen two years running, from 239,000 jobs in 2022/23 to 272,000 in 2023/24 MOD employment estimates. A vague advert in a tight market gets ignored. A sharp one, naming the standards, the clearances and the systems the person will touch, tells the right specialist this role was written for them.
Start with the problem, not the title. Name the system or programme the specialist will improve, the standards they'll work to, and who they'll report to. Be clear about whether the role is design-focused, assurance-focused or both, because those attract different people. Set out what good looks like in the first three months, so someone can picture the remit even though nobody has held it before.
Then move quickly. With investment creating more than 1,700 new defence jobs since July 2024 GOV.UK, specialists have options, and a slow process loses them. Keep your stages tight, give feedback fast, and make the first conversation count.
