Senior DevOps Engineer

What we do:

Halcyon is the industry’s first dedicated, adaptive security platform that combines multiple proprietary advanced prevention engines along with AI models focused specifically on stopping ransomware.

Who we are:

Halcyon was formed in 2021 by a team of cyber industry veterans after battling the scourge of ransomware (and advanced threats) for years at some of the largest global security vendors. Comprised of leaders from Cylance (now Blackberry), Accuvant (now Optiv), Fireye and ISS X-Force (now IBM), Halcyon is focused on building products and solutions for mid-market and enterprise customers.

As a remote-native, completely distributed global team, we recognize great talent can exist anywhere. We invite you to apply to a job you’re interested in and we'll work a plan to meet your needs.

The Role

As a Senior DevOps Engineer, you’ll take technical ownership of our cloud infrastructure and DevOps practices. You’ll help us design resilient systems, scale infrastructure, mentor engineers, and collaborate across product, platform, and security teams.

Responsibilities

• Help us build secure infrastructure on AWS using Terraform, Kubernetes, and related tooling.
• Own and improve CI/CD workflows, enabling fast and reliable deployments across teams.
• Advise and support your fellow DevOps engineers, fostering autonomy, quality, and professional growth.
• Define and track operational metrics, including deployment success rate, infrastructure cost, scaling efficiency, and recovery time.
• Drive incident readiness and response, ensuring strong observability and alerting across systems.
• Collaborate cross-functionally to align infrastructure goals with broader product and platform objectives.

Skills and Qualifications

• 8+ years of experience in cloud infrastructure and DevOps engineering, with 3+ years in senior or leadership level roles.
• Deep experience with AWS and infrastructure-as-code tools (Terraform preferred).
• Proficient with Kubernetes and deployment tooling such as Helm.
• You know CI/CD inside and out—GitHub Actions, ArgoCD, Jenkins, whatever gets the job done.
• You can script in Python, Bash, or something similar.
• Familiarity with observability tools such as Prometheus, Grafana, CloudWatch, Datadog, or ELK/OpenSearch.
• Strong understanding of cloud security practices: IAM, encryption, secure network design, compliance.
• Proven ability to mentor, lead technical initiatives, and drive strategic outcomes.
• Solid understanding of systems performance and reliability, with experience improving deployment reliability and infrastructure scalability.
• Comfortable working in a polyglot environment (e.g., Scala, C#, Python).
• You’ve got strong opinions on infrastructure—and the humility to evolve them.
• You care about security, performance, and doing things the right way.
• You’re collaborative, curious, and not afraid to get in the weeds.

Bonus Skills and Qualifications

• You’ve worked with Kafka, Postgres, DynamoDB, or OpenSearch.
• You’ve designed for multi-region, high-availability environments.
• You’ve played with service mesh tools like Istio.
• AWS certifications? Cool, but not required.
