Title: Senior Site Reliability Engineer
Job Family/Job Family Group: Engineering
Job Level: Senior

About the Role

As a Senior Site Reliability Engineer, you'll join a dedicated, 100% remote team working closely with a major global client in the healthcare and life sciences industry. You will play a pivotal role in ensuring the reliability, scalability, and security of public-facing services by implementing SLOs, automating toil, and managing robust observability platforms. We are looking for someone who is highly communicative, proactive, and thrives in an open, tech-centric culture. You must be comfortable taking the initiative, mentoring fellow engineers, and confidently communicating technical solutions in fluent English to both technical peers and client stakeholders.

Responsibilities:

• Implement and maintain SLOs, SLIs, and error budgets for owned services to balance reliability with feature development.
• Build and maintain observability across services using metrics, logs, traces, and alerting to ensure actionable signals tied to user impact.
• Lead capacity planning, load testing, and resilience testing for critical, public-facing services.
• Automate manual processes and toil to improve operational efficiency, minimize human error, and streamline CI/CD pipelines.
• Contribute to the platform's reliability through Terraform and Kubernetes configuration on AWS, strictly adhering to Cloud Platform standards.
• Participate in on-call rotations and incident management, responding with urgency, troubleshooting complex issues, and driving blameless postmortems.
• Mentor and guide other engineers, fostering a culture of operational excellence, knowledge sharing, and continuous learning within the team.

About You

The essentials:

• Strict geographical requirement: You must be currently residing in Costa Rica (role is 100% remote within the country).
• Extensive hands-on experience as a Site Reliability Engineer managing production systems, including implementing SLOs, error budgets, and incident response.
• Working proficiency managing infrastructure with Kubernetes and Terraform on AWS environments.
• Deep experience with observability platforms (such as Datadog) and designing effective, actionable alert systems.
• Strong scripting and programming skills (e.g., Python, Go) for automation and custom tooling.
• Outstanding communication skills and fluent English; you must be proactive, participate actively with your camera on, and comfortably articulate technical solutions without relying on AI-generated scripts.

Not a Must but a Plus:

• Experience using agentic AI tools (e.g., Claude Code, MCP-based integrations) to automate engineering or operational workflows with appropriate guardrails and human oversight.
