About The Role

Kai is seeking a highly skilled Senior DevOps Engineer to design, build, and maintain secure, scalable, and reliable infrastructure for our cybersecurity platform. This role bridges development, operations, and security — ensuring fast and secure delivery of software in a security-driven environment where your decisions directly impact the products protecting some of the world's largest enterprises.

You will play a key role in embedding security into the DevOps lifecycle (DevSecOps), improving system resilience, and supporting mission-critical applications.

What You'll Do

Design, implement, and manage cloud infrastructure (AWS, Azure, or GCP) with a focus on security and scalability
Design and own network architecture — including environment segregation, service communication patterns, and infrastructure security design in partnership with the security team
Automate infrastructure using Infrastructure as Code (Terraform, CloudFormation, etc.)
Build and maintain CI/CD pipelines, including GitOps-based continuous deployment using ArgoCD, to enable rapid and secure software delivery
Own and optimize the observability stack — metrics, logs, and distributed tracing — as a highest-priority investment in system visibility, incident response, and reliability
Collaborate with engineering and security teams to enforce DevSecOps best practices and embed security into every stage of the delivery lifecycle
Work with the security team to balance deployment speed with security constraints across environments, solving the security-speed tension in POC and production deployments
Collaborate closely with engineering teams to increase developer velocity — faster code pushes, cleaner CI/CD, and fewer deployment blockers
Ensure systems meet security and compliance standards (e.g., SOC 2, ISO 27001, FedRAMP)
Integrate security tools (e.g., vulnerability scanning, secrets management) into pipelines
Troubleshoot production issues and lead root-cause analysis for complex incidents
Optimize system performance, reliability, and cost efficiency
Mentor junior engineers and promote DevOps culture across teams

Required

WHAT YOU'LL BRING

Bachelor's degree in Computer Science, Engineering, or a related field (or equivalent experience)
7+ years of experience in DevOps, SRE, or platform engineering
Strong experience with:
Cloud platforms (AWS, Azure, or GCP)
Containers and orchestration (Docker, Kubernetes)
CI/CD tools (Jenkins, GitLab CI, GitHub Actions)
GitOps and continuous deployment tooling — ArgoCD or equivalent
Experience designing network architecture — environment segregation, service communication, and infrastructure security patterns
Experience with infrastructure automation and configuration management
Proficiency in scripting/programming (Python, Bash, or Go)
Deep understanding of Linux systems and networking
Experience implementing and optimizing monitoring, logging, and observability solutions, including distributed tracing
Strong problem-solving skills in complex distributed systems — CI/CD pipeline optimization, system reliability, performance tuning, and cross-team collaboration
Cloud security mindset — understanding of cloud security, compliance, and DevSecOps practices

Preferred

Experience in cybersecurity or DevSecOps environments
Familiarity with zero-trust architecture and identity/access management
Knowledge of compliance frameworks (FedRAMP, NIST, SOC 2)
Experience with secrets management tools (Vault, AWS Secrets Manager)
Background in incident response and security operations
