LeanData helps the world’s fastest-growing companies automate, simplify, and accelerate revenue.

We are looking for a Senior Site Reliability Engineer to lead the strategic evolution of our cloud infrastructure. Reporting directly to the SVP of Engineering, this role is designed for a builder - someone who wants to move beyond maintenance and into the realm of architectural transformation.

You will have the autonomy to evaluate our existing AWS footprint and lead the charge in modernizing our environment. Your mission is to take a high-velocity system and implement the best practices, guardrails, and automated architectures that will support our next 10x of scale. You will be the primary authority on reliability, performance, and infrastructure security.

Please note: This is a hybrid role based in our Santa Clara, CA office, with an in-office schedule of two days per week – Monday and Wednesday.

Key Responsibilities

• Architectural Modernization: Lead the design and implementation of a scalable, "Cloud-First" AWS architecture. You will drive the transition toward fully automated, state-of-the-art Infrastructure as Code (Terraform).

• High Availability & Resilience: Design and implement robust Disaster Recovery (DR) and Business Continuity plans, moving our services toward a zero-downtime deployment model.

• Performance & Capacity Engineering: Own the strategy for capacity planning and autoscaling. You will optimize our compute resources (EC2, Lambda) to handle bursty traffic patterns with precision and cost-efficiency.

• Advanced Observability: Define our monitoring and alerting philosophy using New Relic for deep APM and system insights. Partner this with IncidentIO to ensure we catch and resolve issues before they impact customers.

• Streamlined CI/CD: Partner with feature teams to refine Change Management and CI/CD pipelines, ensuring code moves from "commit" to "production" safely and predictably.

• Cloud Security: Harden our network architecture and application security posture, including WAF management and secure service-to-service communication.

The Tech Stack

• Cloud Infrastructure: AWS (EC2, Lambda, SQS, SNS, ALB, API Gateway, S3, WAF).

• Observability & Incident Response: New Relic (APM/Infrastructure), IncidentIO.

• Automation & Tools: Terraform, Redis/Elasticache, Shell Scripting, NPM/PM2.

• Application Ecosystem: NodeJS, Python, C#, Angular, Apex.

• Integration: Salesforce Managed Packages, MSFT Dynamics365.

Who You Are

• Experienced Architect: 5+ years of experience in SRE, DevOps, or Systems Engineering, with a proven track record of managing complex AWS environments.

• Proven Incident Commander: You demonstrate calm, decisive leadership during high-pressure outages. You have extensive experience running blameless postmortems and, crucially, driving the remediation work needed to prevent recurrence.

• Observability Pro: You have deep experience configuring New Relic (or similar platforms) to create meaningful dashboards, SLIs, and SLOs.

• Automation Advocate: You believe that manual intervention is a bug. You have deep experience with Terraform and a "Code-First" approach to infrastructure.

• Strategic Problem Solver: You can look at a complex, "needs-based" architecture and formulate a clear, prioritized roadmap to move it toward industry best practices.

• Collaborative Leader: You enjoy working with feature engineers to help them build "reliability-by-design" into their services.

• Education: A Bachelor’s degree in Computer Science, Engineering, or a related technical field (or equivalent professional experience).
