DevOps Engineer

About the Role

We are looking for an experienced DevOps Engineer to join our infrastructure/platform team under our sister company,

AngelHack Developer Labs

. You will design, build, and maintain scalable cloud infrastructure and CI/CD pipelines, with a strong focus on AWS and Red Hat OpenShift environments. This role has a strong

DevSecOps

component — you will be expected to embed security practices throughout the development and deployment lifecycle, not treat it as an afterthought.

Key Responsibilities

Infrastructure & Platform

Design, implement, and maintain infrastructure-as-code (IaC) for AWS cloud environments

Deploy, manage, and optimize containerized applications on Red Hat OpenShift (OKD/OCP)

Manage Kubernetes/OpenShift clusters, including scaling, upgrades, and patching

Troubleshoot and resolve infrastructure, networking, and deployment issues

CI/CD & Automation

Build and maintain CI/CD pipelines to support development and release cycles

Automate repetitive operational tasks to improve deployment speed and reliability

Implement pipeline security gates (e.g., automated approval blocks on failed scans)

DevSecOps / Security Integration

Embed security checks across the SDLC ('shift left') — including static application security testing (SAST), dynamic testing (DAST), and software composition analysis (SCA)

Perform container/image vulnerability scanning before deployment to OpenShift (e.g., Trivy, Clair, Red Hat ACS/StackRox)

Manage secrets securely using tools like HashiCorp Vault, AWS Secrets Manager, or OpenShift Secrets

Implement policy-as-code and compliance-as-code (e.g., Open Policy Agent, OPA Gatekeeper) to enforce security and governance guardrails

Apply IAM least-privilege principles across AWS and OpenShift RBAC configurations

Monitor for security vulnerabilities, misconfigurations, and compliance drift in infrastructure and pipelines

Support security audits, vulnerability remediation, and incident response processes

Collaborate with security teams to align with organizational compliance frameworks

Monitoring & Reliability

Implement and maintain monitoring, logging, and alerting solutions (e.g., Prometheus, Grafana, ELK/EFK)

Support disaster recovery, backup strategies, and incident response procedures

Document infrastructure architecture, security controls, runbooks, and operational procedures

Requirements

Practical experience with

Red Hat OpenShift

(deployment, cluster management, operators, RBAC)

Solid understanding of containerization technologies (Docker, Kubernetes)

Experience with CI/CD tools (e.g., Jenkins, GitLab CI, GitHub Actions, Tekton)

Working knowledge of security scanning tools (SAST/DAST/SCA — e.g., SonarQube, Snyk, Checkmarx, OWASP ZAP)

Experience with container/image scanning tools (Trivy, Clair, Aqua, or Red Hat ACS)

Familiarity with secrets management tools (Vault, AWS Secrets Manager)

Proficiency in scripting languages (Bash, Python, or Go)

Familiarity with configuration management tools (Ansible, Chef, or Puppet)

Understanding of networking fundamentals (DNS, load balancing, firewalls, VPNs)

Experience with monitoring/logging tools (Prometheus, Grafana, ELK/EFK stack)

Strong problem-solving skills and ability to work independently under pressure

Good communication skills and ability to collaborate across Dev, Ops, and Security teams

Good to Have

Red Hat Certified Specialist in OpenShift Administration (or equivalent)

Security certifications (e.g., CompTIA Security+, Certified Kubernetes Security Specialist - CKS)
