About the role:
Own the Portsmouth project interface-management system and drive closure of the cross-functional, contractual, technical, physical, schedule, and organizational interfaces that create execution risk. This role converts interface management from a register into an operating discipline that assigns ownership, dates, decisions, handoffs, and escalation paths across the owner team, EPC/EPCM contractors, utilities, OEMs, infrastructure providers, and external stakeholders.
What success looks like in the first 6-12 months
Single interface-management framework, register, ownership model, and escalation process operating across the program. Critical interfaces across generation, transmission/interconnection, water, gas/fuel, site infrastructure, permitting,
OEM packages, tenants/customers, and EPC/EPCM scopes assigned and actively managed.
Interface agreements, battery limits, inputs/outputs, required-by dates, and decision dependencies reflected in engineering, procurement, construction, and the integrated master schedule.
High-risk interfaces reviewed routinely with accountable owners and unresolved items escalated before they affect critical path or field execution.
DOR/RACI and contractor handoffs remain current as scopes, contracts, organizations, and execution sequencing evolve.
Key responsibilities
Develop and administer the owner-side interface-management strategy, procedure, register, governance cadence, and escalation model.
Identify and structure technical, physical, contractual, schedule, information, organizational, and external interfaces across all major Portsmouth workstreams.
Assign interface owners, counterparties, deliverables, required-by dates, acceptance criteria, dependencies, and closure evidence; challenge ambiguous or ownerless interfaces.
Lead recurring interface reviews with Project Delivery, Engineering, Program Controls, Procurement, Commercial, Permitting, Construction, utilities, Owner Engineer, PMO, EPC/EPCM, and OEM teams.
Ensure battery limits and scope boundaries are explicit across EPC/EPCM packages, owner-furnished equipment, transmission/interconnection, gas/fuel, water, enabling works, controls, commissioning, and tenant/customer requirements.
Coordinate with Program Controls so key interface milestones, constraints, dependencies, and decision dates are embedded in the integrated master schedule and risk process.
Coordinate with Engineering & Technical to drive timely resolution of multidisciplinary design interfaces, technical inputs, design criteria, vendor data, and utility requirements.
Coordinate with Commercial and Procurement where unresolved interfaces create scope gaps, change exposure, claims risk, procurement ambiguity, or contractual responsibility questions.
Support construction and commissioning readiness by confirming interface closure before work-front release, system turnover, energization, startup, and performance testing.
Escalate unresolved or conflicting interfaces with clear facts, owner/counterparty position, schedule/cost
consequence, recommended decision, and latest responsible date.
Key interfaces
Project Director, Delivery; Director, Engineering & Technical; Director, Program Controls & Governance; Commercial; Procurement; Permitting; Gas/Fuel Supply; Construction/Site Delivery; Operations.
PMO, Owner Engineer, EPC/EPCM contractors, OEMs, utility/interconnection teams, gas and water providers, site development partners, commissioning teams, and external consultants.
Tenant/customer technical teams, local agencies, infrastructure providers, and SoftBank functions where owner decisions or shared responsibilities affect execution.
Required qualifications
Bachelor degree in engineering, construction management, project management, or related technical field.
10+ years of experience on large capital projects in power, utilities, oil and gas, transmission, industrial infrastructure, data centers, or comparable complex programs.
Demonstrated experience managing multidisciplinary interfaces across owner, EPC/EPCM, OEM, utility, consultant, and external stakeholder organizations.
Strong understanding of interface registers, battery limits, DOR/RACI, schedule dependencies, change control, design coordination, construction readiness, and commissioning handoffs.
Experience identifying scope gaps and resolving issues that cross engineering, procurement, commercial, schedule, permitting, construction, and operations boundaries.
Strong facilitation and executive communication skills with ability to force clarity without creating unnecessary process.
Ability to operate effectively in a matrix organization and drive closure without full line authority.
Preferred qualifications
Experience with gas-fired power generation, transmission/substations, utility interconnections, gas pipelines, water infrastructure, or hyperscale data center programs.
Experience on multi-billion-dollar EPC/EPCM programs with multiple prime contractors and owner-furnished equipment packages.
PMP, PgMP, PE, AACE, or equivalent project/engineering credential.
Experience with interface-management or requirements-management systems integrated with PMIS, schedule, document control, or risk tools.
Experience supporting commissioning, energization, system turnover, and operations-readiness interfaces.
Leadership attributes
Relentless closer: focuses on getting interfaces resolved, accepted, and documented rather than merely tracked.
Integrator with authority: can convene senior technical and commercial stakeholders and force clear accountability.
Execution minded: prioritizes interfaces based on critical path, field readiness, safety, quality, and commercial exposure.
Low-ego operator: works across organizational boundaries without competing for scope ownership.
High judgment: distinguishes material interfaces from administrative noise and escalates only what requires
leadership attention.
