You will operate as a peer to the DevOps and Platform Engineering leads driving a unified reliability strategy across the organization.

Your core mandate: ensure Obsidian detects every system failure before customers doand communicates proactively when issues arise.

This is a hands-on technical leadership role with high ownership and visibility reporting directly to the CTO. You will architect and implement systems that handle real-world complexity: upstream SaaS dependencies sparse and noisy data and mission-critical enterprise workloads.

Key Responsibilities:

• Map and instrument critical system paths for top-tier enterprise customers

• Expected sparse/low-signal scenarios
• Establish tiered incident communication:
• Public status page for all customers
• Direct outreach for high-priority accounts
• Define and begin rollout of SLI/SLO standards across microservices
• Develop self-service instrumentation tooling enabling engineering teams to own observability
• Implement baseline-aware anomaly detection across all connectors (beyond static thresholds)
• Mature incident response processes including:
• Structured post-mortems
• Continuous reliability improvements

Required Qualifications

• 7 years in SRE production engineering or similar roles
• 2 years operating as a technical lead
• Deep expertise with:
• AWS and/or GCP
• Kubernetes Helm
• Observability stack (Prometheus Grafana)
• CI/CD systems (GitLab CI/CD ArgoCD)
• Proven experience building monitoring for multi-tenant SaaS systems with complex data pipelines
• Strong debugging skills across distributed microservices and legacy systems
• Hands-on engineering mindset able to instrument services directly not just configure tooling
• Track record of building or significantly improving incident detection and response systems

Preferred Qualifications

• Experience in B2B SaaS serving enterprise or financial customers
• Familiarity with third-party SaaS connector ingestion patterns
• Experience building anomaly detection systems or baseline-aware alerting
• Experience implementing customer-facing status pages and incident communication frameworks

Why This Role

• Direct impact: Work closely with the CTO and shape company-wide reliability strategy
• Greenfield opportunity: Build a detection and reliability platform from the ground up
• Technically challenging: Solve for multi-tenant systems with upstream dependencies and sparse data
• High stakes: Protect systems relied upon by major financial institutions

What Success Looks Like

• Obsidian consistently detects and diagnoses issues before customers are impacted
• Clear proactive communication builds customer trust during incidents
