Lead Tech SRE

This is a fully remote position, open to applicants in Europe.

📋 Description

• Take responsibility for the target architecture of Kestra Cloud on GCP, encompassing dedicated stacks for each customer, templating, versioning, regional deployments, and the progression from Beta to GA.

• Create design documents, RFCs, and ADRs that translate product requirements into actionable infrastructure tasks.

• Establish SLOs and error budgets for each service and tier.

• Lead a team of three, which includes two Site Reliability Engineers (SREs), while remaining actively involved in hands-on tasks.

• Break down specifications into manageable work items, delegate tasks, review outputs, resolve issues for the team, and set standards for Terraform, Helm, and GitOps.

• Automate the provisioning, upgrades, scaling, backups, migrations, and decommissioning of customer instances.

• Oversee Kestra Cloud releases utilizing ArgoCD and GitHub Actions, which includes managing progressive rollouts, rollback procedures, and ensuring upgrade safety.

• Implement observability through metrics, logs, traces, and alerting systems.

• Manage on-call duties and incident response activities, including rotations, running runbooks, conducting blameless postmortems, and following up on issues.

• Plan for capacity and manage autoscaling effectively.

• Lead GCP FinOps initiatives, ensuring cost visibility per customer, optimizing resource usage, and managing committed usage and spot instances appropriately.

• Strengthen the platform's security with network policies, workload identity, secrets management, and audit trails to meet SOC 2 standards.

• Integrate platform improvements back into Kestra core engineering efforts.

• In the first six months: audit the existing architecture, publish the GA architecture and SLOs, create a practical roadmap, and achieve milestones in provisioning, observability, and safe upgrades.

⛳️ Requirements

• A minimum of 8 years' experience in Site Reliability Engineering, platform engineering, or infrastructure engineering.

• At least 2 years of experience in leading the technical direction of a team or platform.

• Extensive, production-level Kubernetes expertise, including the operation of cluster fleets at scale.

• Strong experience with Google Cloud technologies, specifically GKE, IAM, VPC, private clusters, load balancing, and managed data services.

• Equivalent proficiency in AWS or Azure does not replace the need for Google Cloud expertise.

• Proficient in Terraform, including creating scalable module structures and managing state layouts.

• Ability to design and write specifications, articulate trade-offs, assign tasks, and deliver projects effectively.

• Significant on-call and incident management experience, including conducting postmortems and implementing sustainable fixes.

• Experience in SaaS operations with paying customers and well-defined SLOs.

• Fluency in English.

• Comfort in working independently within a fully remote setting.

• A pragmatic approach to making technical decisions.

• Nice to have: experience with untrusted or user-defined code workloads, fleet control planes, GCP FinOps, SOC 2 or ISO 27001 audits, workflow orchestration, or JVM production environments.
