Instrument Designer

The IC&E Designer - Smart Instrumentation (SI) formerly known as SPI/INtool and AutoCAD, is an essential partner and member of the IC&E Engineering team and plays a key role supporting BD/RD facilities in safe, reliable, and compliant operation. This position provides hands‑on IC&E design execution and documentation support, with a strong emphasis on Smart Instrumentation (SI) content, formerly known as SPI/INTools including AutoCAD-based design execution and drawing updates, as an individual contributor.

This role focuses on field verification, as‑built reconciliation, and execution of approved design changes in Smart Instrumentation (SI) and AutoCAD in support of MOCs, routine maintenance, and capital work.

Responsibilities

Perform field walkdowns and site surveys to verify existing instrumentation and electrical installations.

Execute as‑built reconciliation by translating verified field conditions and redlines into accurate design documentation.

Creation and update of loop data (Loop module).

Wiring and termination design entries (Wiring/Termination modules).

Instrument tag creation and updates tied to approved changes (Instrument Index / tag register).

Verification of Smart Instrumentation (SI) design content (e.g., spec sheet module, instrument index) against field installations and drawings.

Provide CAD‑based IC&E design support for Management of Change (MOC), routine maintenance, and capital projects.

Create, revise, and maintain IC&E design drawings in AutoCAD including:

Wiring diagrams and cable schedules

Motor schematics

Control loop drawings

Panel, marshalling cabinet, and enclosure drawings

General arrangement and installation drawings

Coordinate with IC&E engineers, reliability personnel, and site staff to ensure Smart Instrumentation (SI) design data and AutoCAD drawings accurately reflect approved and as‑built field conditions.

Support Process Safety Management (PSM) requirements by ensuring documentation is accurate, current, and audit‑ready.

Identify discrepancies between Smart Instrumentation (SI), drawings, and field conditions and work them to resolution through established design workflows.

Manage multiple design assignments concurrently and work independently to agreed schedules.

Communicate clearly and proactively with IC&E and site stakeholders.

Required Qualifications

High school diploma or GED with additional advanced specialized coursework in CAD, SmartPlant (INtootls) drafting, instrumentation technology, or electrical design.

Strong working knowledge of AutoCAD for industrial design applications.

Demonstrated hands‑on experience using Smart Instrumentation (SI) for design execution.

Minimum 5 years of industrial IC&E design or CAD drafting experience.

Experience performing field verification and producing accurate as‑built documentation.

Experience working in operating, PSM covered facilities.

Preferred Qualifications

Associate degree in Electrical, Instrumentation or related Drafting & Design Technology.

Extensive experience executing AutoCAD and Smart Instrumentation (SI) design in brownfield environments.

Experience supporting Management of Change (MOC) design execution.

Experience with electrical and instrumentation systems in industrial process facilities.

Strong understanding of IC&E design document lifecycles and as‑built closeout.

10+ years of industrial IC&E design or drafting experience.
