What You'll Be Doing

Job Scope: Generally responsible for performing routine designs of less complex engineering assignments using theoretical knowledge and practical design methods. This work will be performed under direct supervision.

Primary responsibilities will include but not be limited to:

• Lead development and technical review of complex equipment layouts, piping plans, sections, isometrics, fabrication details, tie-in packages, and general mechanical drawings.

• Translate process and project requirements into coordinated mechanical design packages using P&IDs, line lists, piping specifications, equipment data, vendor drawings, laser scans, and field verification.

• Establish design approaches for difficult brownfield installations, including routing, access, maintainability, constructability, lifting, outage, and sequencing constraints.

• Perform checking and quality reviews of drawings, models, BOMs, MTOs, and vendor information produced by internal and external designers.

• Lead field walkdowns and design verification; resolve discrepancies and ensure redlines and final as-builts are accurately incorporated into plant records.

• Apply and interpret plant standards and applicable mechanical and piping codes and specifications, escalating engineering judgments to the responsible engineer when required.

• Coordinate multidisciplinary design interfaces and facilitate model, constructability, and design reviews with engineering, operations, maintenance, safety, construction, and vendors.

• Develop or improve drafting practices, standard details, design workflows, drawing templates, and quality-control checklists.

• Provide design input to estimates, schedules, execution plans, procurement packages, vendor reviews, bid evaluations, and construction work packages.

• Resolve complex field design questions and support construction, commissioning, turnover, and project closeout while maintaining appropriate engineering approvals.

• Identify and communicate design risks, scope gaps, cost impacts, and schedule constraints to project leadership.

• Set a good example with all rules and regulations to achieve 100% universal compliance with HS&E procedures and regulations.

• Participate in or lead design reviews, constructability reviews, safety audits, surveillances, pre-startup activities, and lessons-learned reviews.
