Lead Site Reliability Engineer (SRE)

Description: Lead all production incidents: triage, coordinate response across engineering teams, communicate status to stakeholders, and drive resolution.
Own the incident management process end-to-end: detection, escalation, communication, resolution, and post-mortem.
Write and maintain incident runbooks to enable faster response and reduce dependency on individual knowledge.
Conduct blameless post-mortems after every significant incident. Track follow-up actions and ensure they are completed.
On-Call Operations.
Own and lead the on-call rotation: define schedules, escalation policies, and response expectations.
Continuously improve on-call quality by reducing alert noise, eliminating false positives, and ensuring alerts are actionable.
Analyze on-call patterns to identify recurring issues and drive permanent fixes with engineering teams.
Observability & Monitoring.
Own the observability stack: Datadog (infrastructure monitoring, APM, logging) and Sentry (error monitoring).
Build and maintain dashboards, alerts, and SLOs that provide meaningful visibility into platform health.
Ensure application performance monitoring covers critical user flows and API endpoints.
Identify gaps in observability coverage and systematically close them.
Security Incident Response.
Lead the response to security incidents (data breaches, unauthorized access, credential compromise) in coordination with the Head of Security & Compliance.
Ensure security-related alerts are properly configured in the monitoring stack and escalation paths are clear.
Participate in penetration test remediation validation and post-incident security reviews.
Reliability & Process Improvement.
Drive reliability improvements across the platform by identifying systemic weaknesses (single points of failure, missing redundancy, inadequate failover).
Collaborate with engineering squads to improve deployment practices, rollback procedures, and change management.
Establish and track SLOs/SLIs for critical services and report on reliability trends.
5+ years of experience in Site Reliability Engineering, DevOps, or Production Engineering at a technology company.
Proven experience leading production incidents end-to-end: from initial triage through cross-functional coordination to resolution and post-mortem. This is the core of the role.
Deep, hands-on proficiency with Datadog or similar observability platforms (e.g., Dynatrace, New Relic, Grafana, Prometheus), including infrastructure monitoring, APM, log management, dashboard creation, and alert configuration. You will own our observability platform using Datadog.
Strong working knowledge of Kubernetes in production, specifically AWS EKS. You must be able to troubleshoot pod failures, resource constraints, networking issues, and deployment problems independently.
Solid experience operating AWS managed services in production environments, including RDS, Amazon MQ, and OpenSearch. You should be comfortable diagnosing performance issues, understanding failover behavior, and tuning configurations.
Experience with Sentry or equivalent error monitoring platforms for application-level issue detection and triage.
Proven ability to design and manage on-call rotations, define escalation policies, and build alerting strategies that minimize noise while catching real issues.
Experience defining and tracking SLOs/SLIs to drive reliability decisions and prioritize engineering effort.
Excellent communication skills in English, both written and verbal. This role requires clear, composed communication during high-pressure incidents as well as thorough post-mortem documentation.
Willingness to be on-call outside of standard working hours. This is a startup environment where the CTO and Director of Engineering are themselves on-call. This role is expected to lead that effort and share the same commitment to platform availability.
Nice to have.
Experience establishing an SRE function from scratch at a growing company.
Proficiency in Python, ideally with exposure to Django or FastAPI web application stacks.
Experience with security incident response processes.
Background in B2B SaaS or platform companies.
Experience with CI/CD pipelines and deployment automation (ArgoCD or similar).
