Objective of the Role

Responsible for driving the strategic direction, operational excellence, and continuous evolution of site reliability engineering practices across critical systems and services. This role leads a team of SRE engineers and complex initiatives, ensuring high availability, scalability, and performance. The Senior Lead of SRE fosters cross-functional collaboration, anticipates future infrastructure needs, and aligns SRE practices with business and product priorities, while cultivating a culture of ownership, automation, and resilience and driving operational excellence with engineering teams.

Main Responsibilities

• Build, lead, and inspire high-performing SRE teams, fostering a culture of operational ownership, engineering excellence, and continuous learning.
• Define and execute the strategic roadmap for SRE, integrating best practices in reliability, incident management, observability, and infrastructure automation in alignment with business and product goals.
• Elevate observability across the stack by designing and enforcing standards for telemetry, structured logging, distributed tracing, and service-level dashboards. Ensure 100% coverage of business-critical systems with actionable metrics and alerting along with the engineering teams.
• Act as the technical escalation point for the most complex production issues, leading hands-on incident response and deep root cause analysis in large-scale, low-latency, event-driven architectures.
• Champion automation-first infrastructure practices, enforcing IaC, immutable deployments, and auto-remediation patterns that reduce manual intervention and accelerate delivery.
• Drive architectural and operational improvements through close partnership with Product Engineering, Platform, Security, and Architecture teams. Proactively identify and mitigate systemic reliability risks and performance bottlenecks.
• Lead the definition, adoption, and review of SLIs, SLOs, and Error Budgets, ensuring they are embedded into engineering and product decision-making processes.
• Operationalize change management, chaos engineering, and DR strategies, validating readiness through frequent simulations and failover exercises.
• Mentor and develop SRE leads and senior engineers, scaling internal capabilities and reinforcing technical depth across the organization.
• Represent SRE in architecture boards, and business reviews, aligning engineering reliability strategies with company-wide objectives.
• Promote a culture of autonomy and proactive engineering, encouraging teams to own their services end-to-end with accountability and resilience thinking.
• Serve as a cultural leader within Spin, fostering psychological safety, ownership, and a sense of mission to serve millions of people across LATAM with secure, reliable financial technology.
