Senior Platform/Site Reliability Engineer

Our client is a rapidly growing enterprise software organization that acquires and scales B2B SaaS products. They are building a shared cloud platform that serves as the engineering foundation for a growing portfolio of enterprise applications. This platform provides standardized infrastructure, deployment, observability, automation, and reliability capabilities across multiple products while enabling future growth without proportionally increasing operational complexity.

The organization is investing in modern platform engineering practices, cloud-native technologies, Infrastructure as Code, AI-assisted engineering, and operational automation to build a scalable, highly reliable engineering ecosystem.

They are looking for an experienced Senior Platform & Site Reliability Engineer to take ownership of the shared platform, establish engineering standards, and design the infrastructure that supports multiple enterprise SaaS products. This is a hands-on technical leadership role where you will influence platform architecture, developer experience, operational reliability, and engineering best practices.

Working Hours: This role requires daily collaboration with a U.S.-based engineering team. Candidates must be available to work until at least 3:00 PM EST (U.S. Eastern Time), with flexibility to work beyond these hours when business needs require.

Responsibilities

Platform Engineering

• Own the architecture and operation of the shared platform, including CI/CD, observability, deployment automation, secrets management, and developer tooling.
• Define, implement, and enforce platform engineering standards across multiple products.
• Build and maintain Infrastructure as Code using Terraform or OpenTofu, ensuring all infrastructure is version-controlled, reviewed, and provisioned through automation.
• Develop self-service platform capabilities that enable engineering teams to deploy independently.

Event Streaming & Data Processing

• Design and maintain event streaming infrastructure supporting real-time processing workloads.
• Build and support batch processing infrastructure alongside live transactional systems.
• Ensure reliability, scalability, performance, and cost efficiency of platform services.

CI/CD & Deployment

• Automate recovery for common pipeline failures and improve deployment reliability.
• Implement release management strategies, rollback mechanisms, and deployment patterns such as canary or blue-green deployments where appropriate.

Observability & Site Reliability

• Own and maintain the observability platform using Grafana, Prometheus, Loki, CloudWatch, and related monitoring tools.
• Define Service Level Objectives (SLOs), error budgets, and reliability metrics across multiple products.
• Build intelligent alerting and monitoring solutions that provide actionable diagnostic information.
• Design incident response processes, escalation procedures, and post-incident review practices.
• Implement safe automated remediation for well-understood operational scenarios while ensuring human oversight for complex incidents.

Platform Expansion & Integration

• Assess newly onboarded products for infrastructure maturity, Infrastructure as Code coverage, observability, and security.
• Plan and execute platform integration and modernization initiatives while minimizing operational disruption.
• Support the adoption of standardized platform capabilities across multiple engineering teams.

Engineering Automation

• Leverage AI-assisted engineering tools and automation where appropriate to reduce operational overhead.
• Automate infrastructure provisioning, CI/CD workflows, monitoring, secrets management, and operational tasks while maintaining engineering oversight for high-impact decisions.
