Senior DevOps Engineer

Daylight is a security services company delivering Managed Agentic Security Services (MASS), including MDR, threat hunting, security data lake, and more, through a fundamentally different architecture than traditional security services providers.

Daylight's architecture combines an agentic platform that runs the full cycle from detection to response with security experts from IR and threat hunting backgrounds. The platform collects identity and business context across systems to investigate alerts and continuously learns your environment. Security experts validate decisions, feed insights into the platform, optimize detections, and take over in case of an incident.

The result: security teams move from firefighting to strategic work.

We're looking for a Senior DevOps Engineer to join our Infra & Security team and help build, scale, and optimize our cloud infrastructure. You'll join a small, hands-on team where DevOps goes beyond traditional operations. You'll take ownership of infrastructure challenges end to end — building new solutions, adapting existing technologies, and continuously improving our production environment.

Responsibilities:

• Design, build, and maintain scalable, reliable, and secure cloud infrastructure in a high-scale production environment.
• Build and manage Kubernetes infrastructure, IaC, and CI/CD pipelines.
• Identify infrastructure and operational needs, evaluate build-versus-buy options, and drive solutions from design to production.
• Collaborate with engineering and security teams to improve system reliability, performance, and security.
• Troubleshoot complex production issues and drive them to resolution.
• Participate in on-call rotations.
• Leverage AI-powered development tools and build AI-driven solutions to improve automation, efficiency, and infrastructure operations.

Requirements:

• 4+ years of hands-on experience as a DevOps Engineer in high-scale production environments.
• Experience working with at least two cloud providers (AWS, GCP, or Azure).
• Strong hands-on experience with Kubernetes and Infrastructure as Code (Terraform preferred).
• Hands-on software development experience in Go or Python, beyond scripting and Infrastructure as Code.
• Experience with CI/CD, GitOps, and modern DevOps tooling.
• Solid understanding of cloud infrastructure, security, and production operations.
• A proactive, versatile, and hands-on mindset, with broad technical experience and the ability to independently identify challenges and drive solutions end to end.
• Hands-on experience using AI-powered development tools and building AI-driven solutions for engineering workflows and automation.

Nice to have:

• Experience in a cybersecurity company.
• Experience with large-scale distributed systems and data-intensive environments.
