Senior Site Reliability Engineer

📋 Job Overview

We are looking for a Senior Site Reliability Engineer (SRE / DevOps) to take ownership of production infrastructure across two SaaS platforms: Userflow and Beamer. You will be responsible for the reliability, scalability, security, and cost efficiency of both platforms, which operate on separate technology stacks across US and EU regions. Together, they serve more than 52 million end users, making infrastructure performance and uptime critical to the customer experience. This is a hands-on, senior-level individual contributor role with significant autonomy and direct collaboration with the CTO and engineering team.

🏢 About Userflow

Userflow is a product adoption platform that helps businesses guide users toward realizing the full value of their products. Its capabilities increasingly include AI-powered experiences.

🎯 The Role

You will establish reliability standards, strengthen infrastructure automation, lead incident response, and ensure the platforms can scale as a small engineering team continues to ship rapidly using AI-powered development tools. We are looking for someone who can independently make technical decisions, take ownership of production environments, and balance reliability with development speed.

✅ Key Responsibilities

• Reliability Engineering: Define, implement, and maintain Service Level Objectives (SLOs) for critical customer-facing workflows, including SDK delivery, authentication, the product builder, and AI-powered features.
• Cloud Infrastructure: Own and evolve production infrastructure across GCP and/or AWS, including Kubernetes, networking, autoscaling, and infrastructure upgrades across US and EU regions.
• Database Operations: Manage ClickHouse and relational databases, including PostgreSQL or MySQL, with responsibility for replication, backups, recovery testing, and capacity planning.
• Infrastructure as Code: Maintain and improve infrastructure automation using Terraform or similar tools, covering cloud resources, networking, and Cloudflare configuration.
• Monitoring and Observability: Own observability systems using Grafana, Sentry, and related tools. Establish actionable alerting and maintain visibility into production health.
• Incident Management: Lead on-call operations, production incident response, root cause analysis, and postmortems. Drive preventive improvements based on incident findings.
• Security and Isolation: Implement rate limiting, tenant isolation, and dedicated infrastructure environments for enterprise customers.
• CI/CD and Deployment: Build and maintain reliable deployment pipelines, progressive delivery processes, and fast rollback mechanisms to support frequent releases without compromising production stability.
• Cost Optimization: Monitor and optimize infrastructure spending, including cloud resources and AI/LLM usage.
• Compliance: Support security controls, documentation, and evidence collection for SOC 2 compliance.

📌 Required Qualifications

• 7+ years of experience in SRE, DevOps, Platform Engineering, or a closely related role.

• Strong written and verbal communication skills, with the ability to collaborate directly with engineers and executive leadership.
• English proficiency: C1 or C2, with the ability to communicate technical decisions clearly in a distributed, international team.

⭐ Desirable Experience

• Experience using AI coding agents such as Claude Code or similar tools for infrastructure automation and engineering workflows.
• Advanced experience with the Grafana ecosystem, including Prometheus, Loki, and Grafana OnCall.
• Previous experience supporting SOC 2 or ISO 27001 audits.
• Experience operating embedded JavaScript SDKs or mobile SDKs at scale.
• Experience managing dedicated infrastructure or isolated environments for enterprise SaaS customers.
• Experience optimizing cloud infrastructure and AI-related operational costs.

🎁 Benefits

Compensation: USD-based, to be determined based on experience and technical expertise.
