Senior Site Reliability Engineer (SRE) Team Lead

About the Job

At XP Venture Labs, we partner with ambitious companies to solve complex technology challenges and accelerate growth. Our teams are composed of highly skilled engineers, architects, and technology leaders who bring deep technical expertise and real-world delivery experience. We don’t operate as traditional consultants. We embed as strategic partners to aid in designing scalable systems, modernizing platforms, improving reliability, and helping our clients navigate high-impact technical decisions with confidence.

From cloud architecture and distributed systems to platform engineering and large-scale modernization initiatives, we specialize in solving the kinds of problems that demand precision, experience, and a relentless focus on outcomes.

About the Role

The Senior Site Reliability Engineer (SRE) Team Lead plays a critical role in ensuring the reliability, scalability, performance, and security of our production systems. This position blends deep technical expertise with hands-on leadership, operational excellence, and close cross-functional collaboration across Engineering and DevOps. The ideal candidate fosters a strong culture of reliability, designs resilient and scalable infrastructure, and mentors a high-performing SRE team that proactively prevents issues rather than simply reacting to them.

This is a high-impact leadership opportunity at a pivotal stage in our growth. As we scale our platform to support major company-wide initiatives, you will help shape the future of our reliability strategy. You’ll have the autonomy to evaluate and introduce new tools and technologies, establish best practices, and define the standards and operational procedures that will guide the SRE function moving forward.
