The Senior Capacity Planning Engineer brings both technical depth and cross-functional instincts to operate effectively at the intersection of supply chain strategy and global infrastructure delivery. You perform at your best under pressure and exhibit poise grace and competence. You can balance strategy and tactics and are always several chess moves ahead of the status quo. You can influence to the net benefit of F5 and InfrastructureEngineering and operate with extreme independence.
In this role you will own the alignment between F5s supply planning strategy and its infrastructure capacity needs ensuring the right compute networking and storage resources are available at the right time in the right locations to support a global infrastructure footprint that is actively growing.
This is a cross-functional role by design. Youll work directly with Supply Chain Network Engineering Infrastructure Operations Finance Product Sales and Procurement as the connective layer that turns capacity signals into supply decisions and supply constraints into planning inputs. The job is ensuring F5s infrastructure can deliver the performance its customers depend on.
Requirements:
- Be Kind
- Define and execute supply planning strategies that keep inventory levels optimized compress lead times and ensure F5s supply commitments stay consistently ahead of global infrastructure expansion.
- Drive capacity planning from end to end with accountability for hardware deployments that simultaneously meet performance standards cost targets and delivery timelines.
- Work closely with Product and Engineering to understand how roadmap commitments translate into infrastructure demand and push back with data when forecasted demand doesnt align with available or procurable capacity.
- Engage with vendors and OEM partners on hardware roadmaps supply chain lead times and capacity-relevant product transitions. Understand the procurement landscape well enough to factor it into your planning assumptions especially in constrained supply environments.
- Collaborate with Procurement to build sourcing strategies that are risk-aware budget-aligned and structured to support F5s infrastructure objectives at scale.
- Engage Infrastructure Operations and Data Center teams to optimize deployment processes sharpen workflow efficiency and hold on-time delivery commitments across both new site launches and existing infrastructure.
- Build and continuously refine demand forecasting models that tie infrastructure requirements directly to business growth signals traffic patterns and shifting customer needs.
- Define utilization thresholds headroom targets and refresh cycles that balance cost efficiency against performance risk and operational resilience.
- Raise the operational ceiling of the capacity planning function by identifying and implementing tools methodologies and process improvements that increase speed analytical depth and planning accuracy.
- Advance the teams use of AI-driven analytics and forecasting techniques applying them where they meaningfully improve the quality of strategic decisions and the scalability of infrastructure planning.
- Deliver data-driven capacity insights and concrete recommendations to senior leadership via clear real-time reporting artifacts providing the analytical grounding needed to make confident infrastructure investment and resource allocation decisions.
What Youll Bring
Required Qualifications
- 8 years of experience in infrastructure capacity planning infrastructure engineering or a closely related discipline with a track record of owning capacity planning functions.
- Demonstrated expertise in compute capacity planning at scale including hands-on experience building demand forecast models defining utilization policies and managing capacity roadmaps across large multi-site production environments.
- Hyperscale or SaaS background: Youve done this at a company where infrastructure runs at scale.
- Compute architecture depth: You understand compute and network hardware at a level that lets you reason about generations form factors power envelopes memory and storage configurations and what those choices mean for capacity math.
- Broad infrastructure literacy: You dont need to be a network or security engineer but you need to understand how network bandwidth security appliance capacity and physical data center constraints interact with compute capacity planning and you need to be able to work fluently across those domains to produce a single integrated capacity model.
- Strong analytical and modeling skills: Proficiency in tools and methods for building validating and communicating capacity models whether thats Python SQL advanced Excel or purpose-built capacity planning platforms. The tool matters less than the rigor. The result however must be a dashboard queryable agentic AI or other real-time artifact not a PowerPoint deck.
- Operational credibility: Youve been close enough to production infrastructure to understand what utilization numbers mean what breaks when capacity runs out and how to translate that operational reality into planning decisions that engineering and operations teams will trust and follow.
- Clear executive-ready communication: You can write a crisp capacity briefing present it to a VP defend your assumptions and translate complex infrastructure analysis into the language of business risk and investment.
- Proficiency with monitoring and observability tools (e.g. Prometheus Grafana Datadog).
- Solid knowledge of system performance metrics (CPU memory disk IOPS network throughput).
- Experience with capacity forecasting methodologies and workload modeling.
- Bachelors degree in computer science Engineering or a related field or equivalent practical experience
