Role · PLC & Controls
Engineers who own the control system end to end — architecture, specifications, network and safety design, vendor coordination and acceptance sign-off. Verified and escrow-protected.
A controls engineer owns the control system as a system. Where a PLC programmer executes within a defined architecture, the controls engineer defines it: the functional specification, the controller and network architecture, the electrical and safety concept, the interfaces between machines and vendors, and the acceptance tests — FAT and SAT — that decide when the system is actually done. On a greenfield line or a multi-vendor integration, this is the role that keeps twenty moving pieces coherent.
It is also the role where a bad hire costs the most, because the mistakes are architectural: an undersized network, a safety concept bolted on late, interfaces nobody owns until they fail during commissioning. We screen controls engineers on design and integration judgment — not just code — and certify them in the PLC & Controls track at three levels, so you can put verified seniority on the decisions that are hardest to undo.

Indicative blended hourly-rate ranges by region, aligned with our live /rates benchmarks. Development work sits toward the middle of each range; on-site commissioning carries a premium. Platform escrow fee is 15% (5% for founding customers).
Every engineer passes a practical AI technical screener before they can be matched at all. Beyond that, they can earn certification in this track at three sequential levels — each higher level requires holding the one below it. Exams mix auto-graded multiple-choice with AI-scored scenario and analysis questions; results are reviewed by a platform admin before any certificate is issued, failed attempts carry a cooldown before retake, and only certified engineers can be assigned to your project.
Solid fundamentals — executes well-specified ladder/ST work under some guidance.
Owns a scope end to end, makes sound design decisions, delivers with minimal oversight.
Architects control systems, handles difficult commissioning and safety, leads technically.
Scope the work and break it into milestones — our AI intake helps structure the brief before any engineer sees it.
You are matched with pre-screened engineers certified in this track — filter by platform depth and certification level.
Funds for each milestone are held in escrow before work starts — the engineer knows the budget is real; you keep control of release.
Review each milestone deliverable and release payment on acceptance. If something is contested, a defined evidence-based dispute path protects both sides.

When the shape of the system is still open. If you are specifying a new line, coordinating several machine builders, choosing the network and safety architecture, or migrating a plant standard, someone has to own those decisions and their documentation — that is controls engineering. If the design exists and the work is writing and commissioning logic inside it, a PLC programmer is the better-priced fit.
The functional design specification, controller and network architecture, the safety concept and its required performance levels, I/O and interface definitions between vendors, the FAT/SAT test plans and their sign-off, and technical leadership through commissioning. On milestone-based projects those artifacts — spec approved, design review passed, FAT passed, SAT passed — map naturally onto escrow stages.
At the architecture level the thinking transfers well — network segmentation, safety design and interface discipline are platform-independent. Implementation detail is not, so on our platform you still filter by the installed base the engineer has actually delivered on. For dual-platform plants, a common pattern is one architecture owner plus platform-specific programmers.
Like every engagement: scoped into milestones with funds held in escrow and released as each stage is accepted. Design-heavy scopes typically milestone on documents and reviews (spec, design review, FAT) before site work. Verification is the same as all tracks — a practical AI screening at onboarding that sets your verified score, plus PLC & Controls certification at three levels, reviewed by an admin before issue. Only engineers holding a valid platform certification can be officially assigned — in the PLC & Controls track, if the project requires it.
