Incident Response and Operations

• Participate in production on-call rotations and help improve incident response processes.
• Lead technical investigations and serve as incident commander during major production incidents when appropriate.
• Troubleshoot complex failures across applications, cloud infrastructure, networking, and databases.
• Conduct blameless postmortems and drive corrective actions to prevent recurring failures.
• Develop and maintain operational runbooks, escalation procedures, and recovery playbooks.

Database Reliability and Disaster Recovery

• Maintain and improve the availability, performance, and recoverability of relational databases hosted on AWS.
• Work with Amazon Aurora and RDS, including backups, restores, replication, monitoring, and failover.
• Implement and validate point-in-time recovery and database backup strategies.
• Plan and execute database migrations and infrastructure changes with minimal or no downtime.
• Contribute to disaster recovery planning, recovery testing, and high-availability architecture.
• Help establish and validate recovery time objectives (RTOs) and recovery point objectives (RPOs).

Engineering Collaboration

• Partner with backend, AI/ML, and security engineers to incorporate reliability into system architecture and development workflows.
• Review infrastructure and deployment changes for operational risks.
• Contribute to engineering standards for deployment safety, capacity planning, observability, and disaster recovery.
• Identify opportunities to simplify infrastructure, improve developer productivity, and reduce operational overhead.
• Mentor other engineers on infrastructure reliability, operational troubleshooting, and production engineering practices.

Required Qualifications

• Production experience: 5+ years of hands-on experience operating production systems on AWS, including responsibility for the reliability, security, and availability of business-critical applications.
• Experience at scale: Demonstrated SRE, platform engineering, or DevOps experience supporting mission-critical systems serving thousands of users or operating under similarly demanding availability and reliability requirements.
• AWS expertise: Strong experience with AWS networking, VPCs, IAM, KMS, Secrets Manager, SQS, Lambda, and production cloud architecture.
• Infrastructure as code: Advanced Terraform experience, including module design, state management, reusable infrastructure patterns, and safely applying changes to production environments.
• Observability: Hands-on experience designing production monitoring, logging, distributed tracing, dashboards, and alerting using Datadog or comparable observability platforms.
• Reliability engineering: Experience defining or implementing SLIs, SLOs, error budgets, and actionable alerting strategies.
• Incident response: Proven experience participating in production on-call rotations, troubleshooting high-severity incidents, coordinating technical incident response, and contributing to lasting corrective actions.
• Database operations: Strong experience operating relational databases on AWS, including RDS or Aurora, backup and restore, point-in-time recovery, replication, failover, and production migrations.
• Distributed systems: Strong understanding of distributed architectures, networking, failure modes, scalability, and production performance troubleshooting.
• Deployment engineering: Experience with CI/CD, deployment automation, release safety, rollback strategies, and operational readiness.
• Automation: Proficiency in Python, Go, Bash, or another programming or scripting language used for infrastructure and operational automation.
• Ownership and collaboration: Strong technical judgment, clear communication, and demonstrated ability to independently investigate and resolve complex production problems.

Preferred Qualifications

• Experience with Amazon Aurora or RDS MySQL in high-availability production environments.
• Experience designing and testing cross-region disaster recovery, automated failover, and multi-region architectures.
• Experience leading major production incidents as incident commander.
• Deep experience with Datadog APM, logging, metrics, dashboards, and monitors.
• Experience with Docker, Kubernetes, Amazon ECS, or EKS.
• Experience operating production applications with demanding uptime, latency, throughput, or recovery requirements.
• Experience implementing blue-green deployments, canary releases, and automated rollback mechanisms.
• Experience with database performance tuning, replication issues, schema migrations, and zero-downtime deployment strategies.
• Familiarity with AWS Organizations, multi-account infrastructure, least-privilege access controls, and infrastructure security.
• Experience with performance testing, load testing, chaos engineering, or fault injection.
• Experience supporting applications in government, defense, or highly regulated environments.
• Familiarity with FedRAMP, NIST 800-53, DoD security requirements, or AWS GovCloud.
• Experience supporting real-time systems, secure communications, AI/ML workloads, or data-intensive platforms.
• Experience helping establish reliability practices, operational standards, or SRE processes across multiple engineering teams.
• Active or previously held U.S. government security clearance.

What Success Looks Like

Success in this role means our production systems become more reliable, observable, secure, and easier to operate.

You will help create an environment where infrastructure changes are predictable, deployments are safe, failures are detected quickly, and recovery procedures are documented and tested.

You will improve the quality of monitoring and incident response, reduce recurring operational issues, and automate manual work that slows down engineering teams.

You will work closely with developers to improve how services are designed and deployed, helping ensure reliability is built into our software rather than addressed only after problems occur.

Most importantly, you will help BluJuniper scale its products and engineering organization while maintaining the operational standards required for mission-critical systems.

What We Are Looking For

We are looking for a deeply technical, pragmatic engineer who has personally operated production systems where downtime and performance failures have real consequences.

The ideal candidate has experience troubleshooting complex production issues, managing AWS infrastructure, automating deployments, improving observability, and implementing resilient database and recovery strategies.

You should be comfortable working directly in Terraform, investigating distributed application failures, reviewing database recovery procedures, and collaborating with software teams to improve production reliability.

You take ownership of problems, think proactively about failure scenarios, and know how to balance operational reliability against engineering speed.

This is not a role focused solely on responding to alerts or maintaining existing infrastructure. We want someone who will actively improve our systems, automate operational work, and help engineers deliver reliable software more effectively.
