Kubernetes Engineer / Hybrid / Chelmsford, MA

This company is a leading provider of access control and security management solutions, delivering innovative technology that helps organizations protect people, assets, and facilities around the world. As the company continues its cloud-native transformation, they are investing heavily in modern DevOps practices, Kubernetes, CI/CD automation, observability, and infrastructure modernization. This is an opportunity to work across Azure, Digital Ocean, Kubernetes, TeamCity, Docker, Prometheus, Grafana, and a broad cloud-native ecosystem while helping shape the future of the platform.

This is not a maintenance-focused DevOps position. We are looking for a technology enthusiast who enjoys researching new tools, automating everything possible, and driving continuous improvement. You'll have ownership over engineering environments, deployment tooling, CI/CD pipelines, and observability while collaborating closely with teams supporting production AKS environments. If you enjoy solving complex infrastructure challenges, working directly with customers on real-world deployments, and influencing technical direction, this role offers significant visibility, autonomy, and growth opportunities.

Required Skills & Experience

• Deep Linux expertise, including system administration, troubleshooting, performance tuning, and containerized workloads
• Strong Docker experience, including knowledge of Docker Swarm environments
• Production Kubernetes administration and troubleshooting experience
• Experience supporting on-premises software deployments and customer-hosted infrastructure
• CI/CD pipeline experience with TeamCity, GitHub Actions, GitLab CI, Jenkins, or similar tools
• Experience building deployment packages, installers, or deployment automation for customer environments
• Hands-on experience with monitoring, observability, logging, and alerting platforms
• Experience with load testing and performance testing tools such as k6, Locust, or JMeter
• Understanding of messaging systems such as RabbitMQ, NATS, or similar technologies
• Relational database experience, preferably PostgreSQL
• Strong scripting and automation experience with Python, Bash, Go, or similar languages
• Experience with Git-based source control workflows
• Solid networking knowledge including DNS, TLS, VPNs, load balancing, and firewall concepts
• Strong technical documentation and communication skills
• Customer-facing experience supporting installations, upgrades, or technical deployments

Desired Skills & Experience

• Prometheus and Grafana implementation and administration experience
• Infrastructure-as-Code experience using Terraform, Ansible, or similar tools
• Experience with Mend.io or comparable SAST/SCA security platforms
• Redis and Elasticsearch administration experience
• Azure cloud experience and Azure certifications (AZ-104, AZ-400)
• Digital Ocean infrastructure experience
• Experience supporting air-gapped or highly restricted customer environments
• Familiarity with SOC 2 compliance and security best practices
• Experience with AI-assisted engineering tools such as GitHub Copilot or Claude
• Exposure to physical security, access control, or IoT-related technology platforms
• Experience introducing and driving adoption of modern DevOps tooling and best practices
