[Hiring] Senior Director, Site Reliability Engineering @WEX

Role Description

As the Senior Director of SRE, you will be the architect leader of resilience for our global mobility platform, leading a high-performing organization of engineers dedicated to ensuring that our services—from real-time GPS tracking and dispatching to global payment processing—are seamless, scalable, and secure.

• Define the multi-year SRE roadmap, pivoting from reactive firefighting to proactive, automated platform health.
• Oversee infrastructure that supports millions of concurrent trips across diverse geographic regions, accounting for local regulatory and latency requirements.
• Own the end-to-end incident lifecycle, fostering a blameless culture focused on root-cause analysis (RCA) and permanent remediation.
• Deploy AI/ML models to analyze historical telemetry data to predict capacity "hotspots" and system fatigue hours before they manifest.
• Partner with Product and Engineering VPs to balance innovation speed with reliability via strictly enforced Service Level Objectives (SLOs) and Service Level Indicators (SLIs).
• Work closely with product and commercial partners to drive, prioritize, and work backwards from the customer requirements and exceed expected outcomes.
• Drive effective monthly, weekly, and quarterly mechanisms to plan, execute, and audit workstreams.
• Optimize a massive global cloud footprint (AWS/GCP/Azure), ensuring performance doesn't come at the cost of unsustainable burn.
• Champion "Infrastructure as Code" (IaC) and self-service tooling so that developers can deploy safely without manual intervention.
• Establish a robust and clear engineering roadmap to maintain clarity and motivation for the engineering team.
• Maintain career growth plans and provide monthly and quarterly feedback for individuals’ continual progress.
• Establish measurement of metrics-driven dev productivity across Mobility SRE org.
• Comfortably present, influence, and communicate to the senior leadership team.
• Provide regular updates and insights to senior leadership on the challenges and opportunities within the Mobility domain.
• Effectively manage up, across, and down with tangible written strategy documents or plans.

• Excellent leadership, team-building, and dynamic decision-making skills.
• Ability to deal with ambiguity and thrive in a fast-paced, dynamic environment.
• Excellent verbal and written communication skills.
