Why this role matters
This role is critical to how our platform scales and stays reliable. As an SRE Lead, you will shape our infrastructure foundations, define our approach to resilience and observability, and ensure our systems are ready to grow at the same pace as our product. You will work closely with the engineering team and our DevOps partners, bringing both leadership and hands-on expertise. This is a role where strategic thinking meets real execution, with a direct impact on product stability and long-term growth.
What you will do
- Drive resilience and reliability improvements across our infrastructure
- Design and implement monitoring, alerting, and observability practices (SLIs/SLOs, dashboards, alert hygiene)
- Lead incident response culture: reduce MTTR, create playbooks, and ensure we learn from every incident
- Collaborate with our external DevOps team — guiding priorities, reviewing proposals, and ensuring consistency
- Keep our Kubernetes clusters (running on our hardware) healthy, scalable, and predictable
- Partner with product engineers to make deployments smooth and safe
- Write and maintain technical documentation for infra and ops processes
Evolve our Helm-based deployments, GitHub CI/CD pipelines, and automation workflows
About you
- You have solid experience running Kubernetes in production.
- You have strong knowledge of observability stacks (Prometheus, Grafana, Loki, etc.)
- You have a proven track record in incident management: designing processes, running postmortems, and preventing recurrence.
- You are familiar with Helm, GitHub Actions, and containerized workflows
- You have experience working in an SRE culture: SLOs, error budgets, and balancing reliability with delivery speed.
- You have strong communication skills and can confidently lead conversations with both engineers and external partners.
- You are comfortable operating both hands-on (debugging pod crashes, tuning alert rules) and at a higher level (roadmaps, resilience strategies).
