Lead Site Reliability Engineer

Do you want to help make the world safe from cyber attack? 
At Corelight, we believe that the best approach to cybersecurity risk starts with the network.  Attackers can evade endpoint detection, firewalls and many other technologies - but they can’t avoid leaving digital footprints on the networks they traverse.  Built on open-source innovations from Zeek, Suricata and YARA and refined through years of real-world use,  Corelight transforms network footprints from physical, virtual and cloud networks into actionable insights.   Our customers use these insights to speed incident response and proactively hunt for threats.  

As a  Lead Site Reliability Engineer (SRE), you will ensure the stability, performance, and security of our Federal region’s cloud platform. You’ll manage infrastructure and operations with a focus on availability, latency, performance optimization, monitoring, incident response, and capacity planning. This role requires maintaining a FedRAMP-compliant environment and working closely with teams to meet the highest standards of security and compliance.

We adopt an "everything as code" approach, leveraging automation and best practices to create an efficient, reliable, and scalable infrastructure. You will be instrumental in maintaining core infrastructure services that are robust, secure, and capable of processing high volumes of data seamlessly.

The successful candidate must be a U.S. Person and may need to perform work that the U.S. government has specified can only be carried out by a U.S. citizen on U.S. soil.

What You’ll Do

• Collaborate with software engineering teams to ensure the reliability, performance, and security of the Federal region’s infrastructure.
• Design, implement, and manage FedRAMP-compliant infrastructure and systems.
• Establish continuous monitoring, logging, and auditing processes to ensure compliance with FedRAMP controls.
• Partner with security teams to conduct security assessments and implement necessary controls.
• Design and implement scalable infrastructure solutions that support multi-region growth.
• Drive automation efforts, enabling infrastructure and platforms to scale efficiently with a focus on compliance.
• Stay up-to-date on best practices, evolving security threats, and FedRAMP guidelines to maintain a strong security posture.
• Deploy and maintain cloud-native services in AWS that are resilient and elastic.
• Participate in 24x7 incident response and on-call rotations.
• Plan for capacity and work with teams to prepare for platform growth.

Technical Skills

• 8+ years of experience building and operating FedRAMP environments or similarly regulated systems.
• Expertise in AWS services (e.g., EC2, S3, RDS, Lambda, ECS/EKS, Glue, EMR, Redshift, OpenSearch, VPC).
• Deep understanding of the FedRAMP framework, controls, and compliance requirements.
• Proficiency in programming languages such as Python, Go, or Java.
• Experience with big data technologies (Hadoop, Spark, Kafka).
• Strong skills in Infrastructure as Code (IaC) tools like Terraform, CloudFormation, or Ansible.
• Knowledge of containerization and orchestration tools like Docker and Kubernetes.
• Experience with CI/CD tools such as Jenkins, GitLab CI, or CircleCI.
• Proven track record in building and scaling platforms with high availability, resilience, and strict SLO objectives.
• Strong experience with Unix/Linux systems and cloud providers, ideally AWS.

Soft Skills

• Excellent leadership and team management capabilities.
• Strong problem-solving and analytical skills.
• Exceptional communication and collaboration abilities.
• Ability to thrive in a fast-paced, dynamic environment and handle multiple priorities effectively.
