Senior Network Capacity Planner

About the Team

We are seeking an experienced, highly motivated Senior Network Capacity Planner to join our Infrastructure Capacity team. CoreWeave is a dynamic, high-growth technology company, and for this role we especially want someone who independently tackles ambiguous, complex capacity questions and improves how the team solves them.

As a Senior Network Capacity Planner, you will make sure our global data center network infrastructure is optimized for scalability and efficiency. You will own network capacity forecasting and planning in partnership with Network Engineering, Supply Chain, and Finance, at a scale and complexity that spans multiple regions or architecture domains. You will set the standards and processes other planners build on, refine how the broader team approaches capacity modeling, forecasting, and tooling, and mentor others along the way. This role requires deep technical fluency in network design topologies and capacity planning and forecasting models, plus the judgment to balance risk, data, and business priorities in your recommendations.

Key Responsibilities:

• Own capacity forecasting models for network infrastructure across backbone, metro, data center, and edge networks. Continuously refine and automate them, improving the underlying methodology rather than just running the existing model.
• Partner independently with Network Engineering and architecture teams to align physical infrastructure with logical network architecture designs. Flag design trade-offs before they become capacity constraints.
• Own network hardware and optical component forecasting (e.g., switches, routers, optics, transceivers) end-to-end. Anticipate how priorities and lead times will change, align with Finance and Supply Chain Procurement, and adjust supply planning and procurement recommendations to match.
• Own bandwidth, port, and optical transport capacity forecasts based on customer growth, product expansion, and usage patterns, weighing competing signals and evidence to make high-confidence recommendations.
• Independently analyze network utilization trends, identify systemic bottlenecks or inefficiencies, and drive the resulting optimization work to completion.
• Lead scenario and what-if analysis for high-stakes decisions on network expansions and build-outs, and present clear recommendations to stakeholders and leadership.
• Collaborate with data center, compute, and GPU planning teams to keep infrastructure capacity aligned across the board, helping teams reach agreement when priorities conflict.
• Own the process for gathering forward-looking requirements and lead-time visibility from Supply Chain teams, and refine it as the team and portfolio scale.
• Own KPIs and dashboards that track network hardware forecast accuracy and network capacity. Make sure they surface the right signals early and clearly for both technical and non-technical audiences.
• Drive requirements and adoption for planning tools, data pipelines, and automation that improve forecasting and visibility, and mentor other planners in using them effectively.
• Mentor and provide technical guidance to other Network Capacity Planners, building a supportive environment through coaching and knowledge sharing as the team grows.

Qualifications:

• Bachelor’s degree in Electrical or Industrial Engineering, Telecommunications, Supply Chain Management, or a related field, or equivalent practical experience.
• 8+ years of experience in network hardware forecasting, capacity planning, network engineering, or infrastructure planning roles, including demonstrated ownership of complex, multi-region or multi-domain initiatives.
• Deep understanding of IP networking, optical transport systems, and data center interconnect architectures, with a track record of improving how a team approaches capacity planning, not just applying existing models.
• Strong working knowledge of routers, switches, and related metrics (e.g., bandwidth, utilization, port density), enough to engage credibly with Network Engineering on design trade-offs.
• Advanced proficiency with data analysis tools such as Excel, Google Sheets, SQL, Looker, or Tableau, including building and maintaining tools or pipelines others on the team rely on.
• Strong analytical, modeling, and forecasting skills, with the judgment to balance risk, incomplete data, and competing input when making high-stakes recommendations.
• Demonstrated ability to work across infrastructure, engineering, supply chain, and business teams, building trusted partnerships and bringing teams into alignment when priorities conflict.
• Experience mentoring or providing technical guidance to less-senior planners or engineers.
• Comfort anticipating how priorities will change in a high-growth, fast-paced environment and adjusting plans proactively rather than reactively.
• Excellent verbal and written communication skills, including the ability to represent capacity planning in cross-functional and leadership-level discussions.

Preferred Skills:

• Experience with network monitoring, inventory management, or capacity planning tools (e.g., NetBox, Grafana).
• Experience formally mentoring or training junior planners or engineers.
• Experience representing network capacity planning in executive-facing forums (e.g., MBR/S&OP).

We support and encourage an entrepreneurial outlook and independent thinking. We foster an environment that encourages collaboration and enables the development of innovative solutions to complex problems. As we get set for takeoff, the organization’s growth opportunities are constantly expanding. You will be surrounded by some of the best talent in the industry, who will want to learn from you, too. Come join us!
