The problem

The Last Ten Per Cent of a Project Eats the Margin

A machine can be fully built, fully wired and physically finished, and still be worth nothing to the customer. Between "installed" and "producing at the agreed rate, tested, accepted and signed off" lies commissioning — and it is the phase where projects lose their margin. The mechanical build ran to plan; the commissioning ran three weeks over because there was nobody who could take the system from powered-up to proven.

The reason this phase is so dangerous is that it sits at the intersection of everyone else's assumptions. The designer assumed the sensors would be positioned as drawn. The installer assumed the sequence would be as specified. The customer assumed acceptance would take two days. Commissioning is where all of those assumptions meet reality at once, under a delivery deadline, in front of a customer who is now paying attention.

A commissioning technician is the profile built for that intersection. Unlike a maintenance technician, who sustains a system that already works, a commissioning technician proves a system for the first time — which is a genuinely different skill. Making a new machine work is not the same as keeping a working machine running, and the calm, methodical temperament it requires is rarer than either raw diagnostic skill or project urgency alone.

  • The gap between "installed" and "accepted" is where project margin is lost
  • Commissioning collides with every upstream assumption at once, under deadline
  • FAT and SAT acceptance is a formal, evidenced process, not a demonstration
  • Handover and training determine whether the customer's team can actually run it
  • The temperament — methodical under pressure, in front of the customer — is scarce

Role overview

What a Commissioning Technician Actually Does

A commissioning technician brings new equipment into operation and proves that it meets specification. The work begins where installation ends: powering up in a controlled sequence, testing functions individually and then together, setting parameters, finding and clearing the inevitable start-up faults, and building the evidence that the system does what the contract says it does.

A large part of the role is the formal acceptance process. Factory Acceptance Testing (FAT) proves the system at the builder's site before shipment; Site Acceptance Testing (SAT) proves it again in the customer's real conditions. Both are evidenced procedures with sign-off, not informal demonstrations, and a commissioning technician who cannot run them methodically will cost the project its acceptance milestone regardless of how well they diagnose.

The role ends with handover: documentation completed, the customer's operators and maintenance team trained, and the early-life problems resolved before the technician leaves. Commissioning technicians work for machine builders, system integrators and equipment suppliers, and the role is heavily project- and travel-based — often weeks on a customer site, sometimes abroad.

When your company needs this profile: when you build, integrate or supply equipment that must be proven and accepted at a customer's site. If the work is sustaining equipment that already runs, you want maintenance or service; if it is deep control-system work, an automation technician. Commissioning is the profile you hire to get from installed to accepted.

Responsibilities

Typical Responsibilities

Explore

Bringing equipment into operation

Powering up in a controlled sequence and taking the system from static to running safely.

Functional testing

Proving each function individually, then proving they work together under real conditions.

Parameter setting and adjustment

Tuning the system to meet the specified rate, quality and behaviour, not just to move.

FAT and SAT support

Running the formal acceptance procedures and producing the evidence that supports sign-off.

Site acceptance

Proving the system in the customer's real conditions, which are never quite the drawings.

Clearing start-up faults

Finding and resolving the early-life problems that only appear once the system actually runs.

Training the customer

Handing over to operators and maintenance so the customer's team can run and keep it.

Project travel

Working on customer sites for the duration of commissioning, frequently away and sometimes abroad.

Skills

Relevant Skills and Experience

Profiles may have experience with the areas below. Commissioning draws on broad technical skill, but the differentiator is rarely a specific technology — it is method and temperament under acceptance pressure.

The best diagnostic technician in your maintenance team is not automatically a good commissioning technician. Commissioning rewards a particular disposition: methodical sequencing, disciplined record-keeping, comfort being the visible technical authority in front of a customer, and the patience to prove a thing rather than assume it. Test for that disposition directly, because it does not show up on a skills list and it is the thing that most often fails.

  • Functional testing — structured, sequenced proving of a system
  • FAT and SAT procedures — running formal acceptance with evidence
  • PLC and control systems — reading behaviour and setting parameters
  • Mechanical and electrical breadth — enough to work across the whole system
  • Fault finding — resolving start-up problems that have no maintenance history
  • Documentation — producing acceptance records and handover packs
  • Customer training and communication — being the face of the project at handover
  • Safety during start-up — energising and testing untested equipment safely

Equipment

Equipment and Systems They Commission

Commissioning experience is best assessed by what a candidate has taken from installed to accepted, and whether they owned the acceptance or merely assisted.

  • Production lines
  • Automated systems
  • Robotic cells
  • Packaging and filling machines
  • Conveyor and handling systems
  • Machine tools
  • Process equipment
  • Industrial control systems

Verification

What Employers Should Verify

  • Owned versus assisted

    Did they run acceptance and sign-off, or assist a lead? The difference is the whole role.

  • FAT and SAT experience

    Actual formal acceptance procedures, not informal demonstrations.

  • Equipment commissioned

    What they took from installed to accepted, and how close it is to your systems.

  • Temperament under deadline

    Methodical and evidence-driven, or fast and assuming? Test it explicitly.

  • Customer-facing ability

    They are the project's face at acceptance and handover. Have them explain a handover to you.

  • Documentation discipline

    Acceptance without evidence is not acceptance. This is non-negotiable for the role.

  • Travel willingness, precisely

    Commissioning means weeks away, sometimes abroad, at project notice. Confirm the specifics.

  • Formal qualification

    Useful context; the acceptance track record matters more.

  • Language ability

    A customer-facing, documentation-heavy role. Verify against your projects' languages.

  • Work permit requirements

    Cross-border commissioning raises posting and permit questions. Confirm with the competent authority.

Recruitment

Recruiting Commissioning Technicians Through Candidate Force

  1. Define the role

    Be explicit about acceptance ownership, travel and the systems involved. These filter harder than any technology.

  2. Explore profiles

    Review commissioning technician profiles on Candidate Force and see what they have taken to acceptance.

  3. Post the vacancy

    State the travel and the project pattern honestly. Commissioning offers are declined most often over travel.

  4. Review applications

    Assess against acceptance ownership, method and customer-facing ability.

  5. Manage the next steps

    Verify qualifications, language and work authorisation individually.
