This is a unique opportunity to join a mission-driven environment and play a key role in ensuring the reliability, scalability, and performance of AWS-hosted business applications.

As part of a cross-functional engineering team, you will work to improve observability, automate operational processes, and lead incident response and continuous improvement efforts. This role is ideal for a mid-level engineer with cloud and software engineering experience who is eager to deepen their expertise in site reliability engineering, learn from senior staff, and help build a culture of reliability.

ESSENTIAL DUTIES AND RESPONSIBILITIES

• Define and implement service-level indicators (SLIs) and service-level objectives (SLOs) for cloud-based applications.

• Build, configure, and maintain monitoring, alerting, and dashboarding solutions using AWS CloudWatch, X-Ray, and third-party tools such as DataDome.

• Leverage advanced AWS observability tools (e.g., CloudWatch Synthetics, Contributor Insights) to proactively monitor system health.

• Contribute to the development and implementation of a structured on-call support process.

• Implement, monitor, and maintain site protection and bot mitigation solutions to defend against automated attacks and ensure application availability.

• Investigate incidents, security events, and operational anomalies, perform root cause analysis, and lead postmortem processes.

• Identify operational inefficiencies (“toil”) and automate workflows using AWS Lambda and CloudFormation.

• Assist in maintaining and enhancing CI/CD pipelines and deployment processes.

• Collaborate with development, QA, cloud, and DevOps teams to ensure reliability, scalability, and security are embedded into system designs.

• Document systems, processes, incident findings, compliance activities, and reliability best practices.

• Stay current with AWS, SRE, and observability trends and recommend improvements.

• Evaluate and support the rollout of new AWS services and features.

• Perform other related duties as assigned.

KNOWLEDGE & SKILLS

• Strong analytical, troubleshooting, and problem-solving abilities.

• Hands-on experience with AWS CloudWatch (metrics, logs, dashboards, alarms).

• Familiarity with AWS X-Ray for distributed tracing.

• Experience with CloudWatch Synthetics and Contributor Insights for proactive testing and analysis.

• Knowledge of AWS CloudTrail for auditing and investigations.

• Experience using AWS Athena for log analysis.

• Proficiency with AWS CloudFormation.

• Experience automating workflows with AWS Lambda or similar tools.

• Understanding of AWS services such as API Gateway, CloudFront, and Elastic Load Balancer (ELB).

• Experience with site protection or bot mitigation tools (e.g., DataDome, Cloudflare).

• Scripting or programming experience in Python, Bash, or Node.js.

• Excellent communication and documentation skills.

• Growth-oriented and eager to adopt emerging tools and practices.

REQUIREMENTS

• Bachelor’s degree in computer science, engineering, or related field (or equivalent experience).

• 3+ years of experience in cloud engineering, DevOps, infrastructure, or observability (AWS required).

• Experience applying SRE principles (prior SRE experience preferred).

• Background in monitoring, incident response, or reliability in production environments.

• Experience working in Agile, cross-functional teams.

• Passion for building and improving reliability practices.
