Senior Cyber Security Engineer (DevSecOps)

ECI•Boston, MA

About The Position

The Cyber Security Engineer (DevSecOps) builds and maintains the automation, pipelines, and integrations that keep ECI’s flagship security platform running. This is a hands-on, implementation-focused role: you will write production Python, ship CI/CD and infrastructure-as-code, and build and operate detection and response workflows in the Elastic Stack (Elasticsearch, Logstash/Beats, Kibana). It suits an engineer with a strong software-development foundation who wants to own the build-and-deploy side of security operations and turn manual work into reliable, automated systems. You will report into and implement the standards set by the Cybersecurity Architect.

Requirements

Degree in Computer Science or Cyber Security, or equivalent hands-on experience
2+ years building software in a professional setting, with strong Python development (services, automation, and APIs, not only light scripting)
Hands-on experience with the Elastic Stack (Elasticsearch, Logstash/Beats, Kibana) for log ingestion, detection, or analytics
Practical CI/CD experience, including automated testing, build pipelines, and secure deployment workflows
Working knowledge of infrastructure-as-code (Terraform, Ansible, or Salt) and configuration management
Proficiency with Git/GitHub in a collaborative engineering workflow
Experience with REST APIs, webhooks, and integrations in automation workflows
Familiarity with core security concepts: logging, alerting, threat detection, and incident response
Working knowledge of Linux and Windows and their security implications
Strong problem-solving mindset and clear written and verbal communication

Nice To Haves

Experience automating detection and response workflows in a SIEM/XDR (Elastic preferred; Splunk or Microsoft Sentinel a plus)
Working knowledge of the MITRE ATT&CK framework and its use in detection engineering
Exposure to SOAR, MISP, or Sigma and detection-as-code practices
Foundational cloud security on AWS or Azure (IAM, shared responsibility model, basic compliance)
Exposure to container security and Kubernetes hardening
Interest in applying AI tooling to security automation

Responsibilities

Build and maintain Python automation, services, and integrations that improve detection, response, and customer experience across the security platform
Develop and operate CI/CD pipelines and infrastructure-as-code (Terraform, Ansible) to deploy and maintain security tooling
Build and tune detection and response content in the Elastic Stack: data ingestion, parsing and normalization, detection rules, and Kibana dashboards
Integrate security tools and data sources using REST APIs, webhooks, and SOAR playbooks
Containerize and deploy workloads with Docker and Kubernetes following secure-deployment practices
Write tests, documentation, and runbooks for the workflows and scripts you ship
Work alongside the Cybersecurity Architect to implement the platform’s reference architecture and detection standards
