M2 - Infra Sr Lead - SRE

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. 

Required Knowledge and Experience 

• Bachelor’s degree in Computer Science, Software Engineering, or related field (or equivalent experience). 

• 10+ years of experience in SRE, DevOps, or Software Engineering roles, with at least 4+ years in leadership roles. 

• Strong experience leading distributed SRE or platform teams in complex, production-scale environments. 

• Deep understanding of reliability engineering principles, cloud-native infrastructure on AWS, observability, and incident response. 

• Hands-on experience with infrastructure as code, CI/CD pipelines, containers, and orchestration tools. 

• Strong architectural and performance optimization skills across cloud and hybrid infrastructure. 

• Demonstrated ability to influence and collaborate across engineering, product, and business teams. 

• Familiarity with regulatory and security frameworks relevant to infrastructure reliability. 

• Excellent communication and leadership skills, with experience presenting to senior stakeholders. 

• Strategic thinking, systems-level problem solving, and a proactive approach to continuous improvement.
