In this role you will be the connective tissue between our Infrastructure organization and the rest of engineering, driving the rollout of critical, cross-cutting programs that affect how we build, operate, and secure our platform at scale. You will juggle a high volume of parallel efforts across cloud infrastructure, FinOps, build systems, software migrations, security operations, and more, keeping each moving, supporting teams to be successful, and escalating quickly when capacity or priority decisions need to be made. This is not a role for someone who waits to be told what to do. It's a role for someone who drives. How you'll make a difference • Own the rollout of infrastructure initiatives across engineering. Drive programs from planning through completion, coordinating across teams that don't report to you and don't always have capacity to prioritize infrastructure work. Keep things moving. • Manage a high volume of concurrent efforts. At any given time you'll be tracking security operations improvements, FinOps initiatives, build system changes, software migrations, and other cross-cutting infrastructure programs simultaneously. Clear prioritization and status visibility are non-negotiable. • Hold teams accountable and escalate when needed. You know how to build the relationships and create the visibility that keeps infrastructure work from getting deprioritized. When a team genuinely lacks capacity, you surface that quickly, bring the right people into the conversation, and get a trade-off decision made — not absorb the delay quietly. • Develop a way to provide program health continuously. Establish and maintain clear, actionable reporting on the status of all infrastructure rollouts. Leadership should always know what's on track, what's at risk, and what decisions are needed from them. • Partner with Infrastructure leadership on planning and prioritization. Work closely with engineering and SRE leadership to build and maintain a rolling roadmap, sequence work across teams, and ensure infrastructure investments align with engineering and business priorities. • Define clear ways of working across teams. Create frameworks, templates, and coordination models that make it easier for infrastructure and product engineering teams to work together effectively. Build the playbook as you go. • Develop deep technical fluency in the programs you own. You don't need to write the code, but you need to understand what's being built, why it matters, and what the technical risks are well enough to ask the right questions, identify blockers early, and represent the work credibly to engineering leadership. • Drive automation and operational excellence. Challenge manual processes wherever you find them. Partner with infrastructure teams to identify opportunities to centralize and automate change rather than default to simply assigning out the same work to different teams. Who you are • Technically fluent. You've worked closely with infrastructure, SRE, or platform engineering teams. You understand security operations, cloud infrastructure, CI/CD, and software migrations well enough to engage substantively, not just track status. • A driver, not a facilitator. You move work forward. You follow up, push back, escalate, and hold people accountable, constructively, but consistently. You don't wait for the next meeting to surface a problem. • Influential and relationship-driven. You know that infrastructure work gets done through trust, not authority. You build strong relationships across engineering teams, understand what motivates different stakeholders, and use that context to create alignment • AI-first in how you work. You don't just talk about AI, you use it daily to move faster, work smarter, and do more with less. You bring that mindset to the teams you work with and actively look for opportunities to automate, accelerate, and improve how programs are run. • Comfortable with high volume and ambiguity. You can manage many parallel workstreams without losing track of any of them, and you don't need a clean problem statement to get started. • Clear and direct communicator. You tailor your message by audience, engineering teams need different information than engineering VPs, and you make it easy for leadership to understand status and make decisions quickly. • Outcome-oriented. You measure success by realizing the impact and what improves, not by the quality of your tracking. Preferred experience (guidance, not gates) • 8+ years of experience in technical program management within a fast-paced product engineering environment, ideally SaaS or high-growth tech. • Demonstrated experience driving large-scale infrastructure rollouts across multiple engineering teams. • Familiarity with cloud infrastructure, FinOps, security operations, and software migration programs. • Strong fluency in tools such as Jira, Linear, Asana, or Smartsheet. • Track record of managing competing priorities and delivering results without direct authority over engineering teams. Nice to haves • Experience in both infrastructure and product engineering contexts. • Familiarity with FinOps frameworks and cloud cost optimization programs. • Experience building or evolving TPM practices in a nascent or growing function. • Hands-on with CI/CD tooling, build systems, or security c
