The Senior Design Integration Engineer provides execution leadership and full design integration ownership for a complex facility and site development project. This role actively manages design interfaces, assumptions, constructability, and change impacts across facility, piping, structural, vendor, and site disciplines.

This position is focused on risk reduction and schedule protection, not just drawing production. The Senior Design Integration Engineer serves as an execution-focused extension of Valar leadership, ensuring evolving inputs are translated into coordinated, buildable designs and that downstream construction issues are identified and resolved early.

This role does not perform nuclear reactor physics or licensing work. 

Primary Roles & Responsibilities

Design Integration & Interface Ownership

Own and manage design interfaces across:

Facility layout

Piping systems

Structural systems

Vendor equipment and skids

Site utilities and infrastructure

Ensure consistency and alignment across drawings, models, and vendor inputs

Serve as the technical point of integration between disciplines

Assumptions & Design Basis Management

Validate, document, and track design assumptions, including:

Equipment loads and envelopes

Clearances and maintenance access

Elevations and interfaces

Construction sequencing constraints

Identify assumption changes early and assess downstream impacts

Execution-Focused Design Development

Translate evolving project inputs into coordinated, buildable designs

Ensure layouts reflect real-world installation, access, and sequencing needs

Challenge incomplete, conflicting, or high-risk inputs before they reach construction

Constructability & RFI Prevention

Lead constructability thinking across disciplines

Identify and resolve:

Installation conflicts

Access and maintenance issues

Temporary support and sequencing concerns

Proactively reduce RFIs, rework, and field-driven design changes

Piping & Structural Support

Provide hands-on support for:

Piping layout, routing, and support concepts

Structural framing, foundations, platforms, and supports

Perform basic piping and structural calculations as required to validate layouts and concepts

Coordinate piping and structural elements to ensure compatibility and buildability

Clash Resolution & Change Management

Lead Navisworks model coordination and clash resolution

Resolve conflicts across disciplines rather than simply reporting them

Manage and communicate change impacts to drawings, models, schedule, and execution sequence

Leadership & Coordination

Act as an execution-focused extension of Valar project leadership

Support coordination meetings and design reviews with practical, build-oriented input

Provide clear recommendations and decision support to leadership

Core Competencies

Interface ownership and accountability

Proactive risk identification and mitigation

Practical, execution-oriented engineering judgment

Strong communication across technical and non-technical stakeholders

Schedule and cost protection mindset

Explicit Non-Responsibilities

Does not perform reactor physics, nuclear analysis, or licensing activities

Does not replace Valar’s core nuclear engineering team

Does not function as a purely drafting or production-only role

Value & Benefits to Valar

Issues identified early, when they are fastest and least expensive to resolve

Reduced RFIs, rework, and field-driven changes

Cleaner coordination across disciplines and vendors

Improved schedule confidence and execution predictability

Lower total project cost despite higher hourly rate

Risks to Valar

Higher upfront hourly cost compared to production-only roles

Requires commitment to proactive execution and early decision-making 

Education / Certifications

Bachelor’s degree in:

Mechanical Engineering

Structural Engineering

Civil Engineering

Professional Engineer (PE) license not required but considered a plus

Experience & Background

12–18+ years of progressive experience

Background in one or more of the following environments:

Industrial facilities

Energy or power projects

Nuclear-adjacent facilities (non-licensing)

Heavy construction or shipyard environments

Demonstrated history of execution leadership, not just design support

Proven ability to operate independently and make sound engineering judgments

Knowledge, Proficiencies & Familiarities

Expert-level proficiency in AutoCAD

Advanced 3D modeling capability

Expert Navisworks coordination and clash resolution experience

Strong working knowledge of:

Piping systems and layout principles

Structural systems and load paths

Construction sequencing and field execution realities

Ability to integrate vendor data and incomplete inputs effectively
