DevOps Engineer II

About the role

You'll be part of a high-performing DevOps team responsible for evolving our cloud infrastructure, CI/CD pipelines, and observability frameworks across environments. You'll have the autonomy to design, build, and optimise our infrastructure systems while enabling developer productivity at scale.

What you'll do

• Design, build, and maintain CI/CD pipelines for all HackerRank environments from development to production.
• Automate infrastructure using Terraform, Docker, and Kubernetes (EKS), ensuring scalability and reproducibility.
• Lead and evangelise DevOps best practices across engineering teams, CI/CD hygiene, observability, and cost-efficient architectures.
• Implement and maintain monitoring, alerting, and incident response systems using tools like OpsGenie, New Relic, and ELK.
• Optimise the performance and utilisation of key systems such as Redis, RDS, Redshift, ElasticSearch, and Kafka.
• Partner with security and platform teams to ensure compliance, resilience, and threat protection across cloud environments.
• Contribute to cloud cost optimisation initiatives and infrastructure efficiency projects.

Who you are

• Bring 3+ years of experience in DevOps, SRE, or Cloud Infrastructure Engineering roles.
• Deep expertise with AWS (and ideally some exposure to GCP), including EKS, EC2, S3, SQS, and IAM.
• Strong experience with Terraform, Docker, Kubernetes, and Linux (Ubuntu)
• Hands-on scripting or coding skills in Python or Java.
• Solid grasp of monitoring, alerting, and performance tuning principles.
• Strong collaborator who can partner with developers, QA, and leadership teams to drive platform improvements.

Even better if you have

• Experience implementing ArgoCD, Jenkins, or other CI/CD orchestration tools.
• Background in security engineering, threat modelling, or penetration testing.
• Knowledge of observability frameworks and modern APM tools (New Relic, Prometheus, Grafana).
• Proven track record in cost optimisation and infrastructure scaling for high-traffic systems.
• Experience working with multi-cloud or hybrid environments.

You will thrive in this role if

• Bring a builder's mindset to automate processes, simplify workflows, and empower others through effective tools.
• Being passionate about reliability, scalability, and developer experience.
• Enjoying owning systems end-to-end and solving production challenges hands-on.
• Balances technical depth with empathy, understanding that infrastructure is successful only when developers can move faster and safer.
• Take pride in creating calm out of complexity and designing systems that just work.
