About Rubix 

At Rubix, we design and deliver end-to-end AI data center infrastructure — from site origination and development through to long-term operations. We partner with customers to scale AI with speed, efficiency, and sustainability, backed by secured land, power access, and accelerated delivery models. 

What Impact You Will Have 

As Planning Manager, you will help Rubix deliver complex data center projects with greater predictability. You’ll build and manage integrated schedules, surface risks early, and keep project teams aligned from planning through commissioning and turnover. 

What You’ll Do 

Own integrated project schedules 

• Develop and maintain master schedules across design, procurement, construction, commissioning, and turnover. 

• Use critical path analysis to identify risks, dependencies, and schedule impacts before they become blockers. 

• Track progress against baselines and provide clear updates on milestones, slippage, and recovery options. 

Bring structure to planning 

• Facilitate planning sessions with internal teams, contractors, consultants, vendors, and delivery partners. 

• Align project schedules with scope, procurement plans, resource assumptions, and key decision points. 

• Create scheduling standards, templates, reporting cadences, and planning tools that can scale across projects. 

Support better project decisions 

• Prepare schedule reports, lookaheads, forecasts, and executive updates that make timing risks easy to understand. 

• Partner with delivery, design, construction, procurement, cost management, and operations teams. 

• Capture lessons learned and use schedule data to improve future planning and delivery performance. 

What You’ll Need 

• 5+ years of planning, scheduling, project controls, or construction delivery experience. 

• Experience supporting large-scale data center, mission-critical, industrial, infrastructure, or complex construction projects. 

• Advanced experience with Primavera P6 and strong understanding of critical path method scheduling. 

• Ability to manage multiple schedules, stakeholders, milestones, and reporting needs at once. 

• Willingness to travel to project sites as needed. 

What Will Make You Stand Out 

• Direct experience with hyperscale, colocation, or AI infrastructure data center projects. 

• Experience planning projects from early development through commissioning and handover. 

• Knowledge of Lean planning, pull planning, 4D planning, earned value, or schedule risk analysis. 

• Direct knowledge of data center construction processes and sequencing to be able to build schedules from scratch to detailed versions without detailed input at every stage. 

• Comfort building scheduling processes in a high-growth environment. 

• Strong communication skills and the ability to turn complex schedule data into clear recommendations. 

• Experience with scheduling techniques and market leading processes available to enhance the process leading to improvements in efficiency and Delivery timelines. 

What We Offer 

• Exposure to high-impact investment decisions in a rapidly growing AI infrastructure platform 

• Opportunity to work across the full asset lifecycle—from origination through operations 

• Direct collaboration with senior leadership and cross-functional teams 

• A fast-paced, entrepreneurial environment with strong growth potential
