Does Your OT Security Hire Need to Be On-Site?
A role can involve industrial systems without requiring every task to happen at a plant. It can also be advertised as remote while demanding enough site travel to make that label misleading. The useful question is which responsibilities require physical presence, how often they arise, and who will cover them.
Decide that before the search begins. Work location affects who can realistically accept the job, what they need to organize at home, and how the employer will support the work. A clear arrangement also gives candidates a fair way to compare the opportunity with their current position.
Start with a month of real work
List the assignments the person is likely to handle: site discovery, design review, control deployment, investigations, documentation, meetings with operations, and preparation for maintenance windows. For each one, ask what requires being there. Walking down an unfamiliar installation is different from reviewing an approved design with a team you already know.
Include the work around the technical task. A change might be prepared remotely but require attendance for commissioning and handover. An investigation might begin with remote analysis but need a local engineer to verify equipment or gather approved evidence. Identify those dependencies instead of assuming that remote access covers them.
Separate planned visits from urgent response
Planned travel and emergency availability are different commitments. A candidate who can spend a scheduled week at a plant may be unable to reach it within an hour. If the business needs someone nearby for urgent work, state the response expectation and explain the backup arrangement when that person is unavailable.
NIST's OT security guidance addresses the safety, reliability, and performance requirements that shape this work. The staffing implication is practical: agree who has the local knowledge and authority to support operational decisions. Being able to connect to a system does not establish that a remote employee can perform every task safely or independently.
Three workable arrangements
| Arrangement | A role it could suit | What to make explicit |
|---|---|---|
| Primarily at one site | An engineer working closely with daily plant activity and frequent local changes. | Normal hours, physical work areas, occasional travel, and after-hours coverage. |
| Hybrid at a defined location | A position combining regular site coordination with design, analysis, and documentation. | Required site days, flexibility during project periods, and the commuting expectation. |
| Home-based with site travel | A position supporting several facilities with established local engineering contacts. | Expected trips, typical duration, notice, eligible home locations, and emergency arrangements. |
Explain what the travel percentage means
A percentage alone tells a candidate very little about their calendar. One overnight trip most months feels different from a long commissioning visit followed by several weeks at home. Describe the usual pattern, the longest likely trip, and any periods when visits become more frequent.
For a fictional multi-site role, a useful description might say: 'Home-based within the approved hiring region, with planned visits to operating sites. Most visits last two or three days. Major deployments can require a full week. The manager agrees the travel schedule in advance, with separate arrangements for urgent incidents.' The employer should replace each detail with its actual expectation.
Discuss travel expenses, booking arrangements, weekend travel, and time outside normal hours before an offer. Candidates should not have to infer these terms from a sentence that says 'travel as needed.' If relocation is necessary, make that clear at the start of the search.
Plan the first months separately
An established employee may work effectively from home because they know the equipment, the people, and the informal paths for getting help. A new hire may need more time on-site to build that understanding. Describe the initial site visits or onboarding period separately from the long-term arrangement.
Also identify local support. If the position depends on a plant engineer for physical access or technical confirmation, agree that person's availability with their manager. A remote model becomes difficult when the local assistance exists only as an assumption in the hiring plan.
Put the arrangement in the hiring brief
Use the same location description in the advertisement, recruiter conversations, interviews, and offer. Include the primary work location, approved geographic boundaries, travel pattern, and response responsibilities. Once those details are settled, the search can focus on people who can do the work and sustain the arrangement.
