Design Manager

Position Overview

The Design Manager leads the design function for DSI's Off-Site Manufacturing division, taking mechanical (HVAC and plumbing) scope for mission-critical and data-center projects from concept through modularization, detailed design, shop fabrication packages, and field installation drawings. The role owns design quality, schedule, and constructability for prefabricated modules, skids, racks, and multi-trade assemblies, and is the primary design interface between customers, engineers of record, DSI project teams, and the fabrication shop.

Key Responsibilities

Design Leadership

Lead modularization strategy for each project: define module boundaries, break points, transport envelopes, rigging/lifting provisions, and site connection points.

Manage development of module design packages — P&IDs, general arrangements, piping isometrics, structural frame/skid drawings, hanger and support details, and bills of material.

Produce and release shop fabrication packages (spool drawings, weld maps, cut lists, nesting) to the fabrication floor on schedule; manage revision control and as-built close-out.

Coordinate design with engineers of record, structural engineers, and customer engineering teams; resolve RFIs and drive design decisions to closure.

Enforce compliance with contract drawings, project specifications, and applicable codes and standards (ASME B31.1/B31.9, ASHRAE, IMC/UPC, AWS D1.1, customer welding and passivation specifications).

BIM / VDC & Coordination

Own the OSM BIM execution plan; set modeling standards, LOD 400 detailing requirements, and Revit/Fabrication content libraries.

Run multi-trade clash detection and coordination sign-off for modules; ensure field-ready models feed layout, fabrication, and QA/QC.

Drive design-for-manufacturing and design-for-assembly (DFMA) practices to reduce shop hours, rework, and field labor.

Team Management

Hire, develop, and manage a team of design engineers, modelers, and detailers; set priorities, review work, and manage workload across concurrent projects.

Establish design KPIs — hours per module, drawing release on-time %, rework/ECN rate, RFI cycle time — and report them monthly.

Build standards, templates, and a library of typical module designs to accelerate repeat data-center product lines.

Preconstruction & Project Support

Support estimating and business development with conceptual module layouts, quantities, and design-hour estimates during pursuits.

Participate in project kickoff, constructability reviews, and factory acceptance testing; support commissioning with design documentation.

Coordinate with Production, Quality, Procurement, and Project Management to align design releases with the fabrication schedule and material lead times.
