- Evaluate complex technical problems across application systems, business processes, and delivery pipelines, and develop engineering solutions that meet specific business requirements.
- Collaborate with development teams, business users, and technology stakeholders to define operating standards, resolve technical issues, and recommend engineering improvements.
- Develop and enforce security measures across the software delivery lifecycle, ensuring system design supports compliance with applicable policies and technical standards.
- Act as a technical authority for junior and mid-level engineers, providing guidance, code review, and hands-on support to elevate team capability.
Required Qualifications & Skills
- 4 to 8 years of experience in software engineering, systems development, or DevOps with demonstrated delivery in complex technical environments.
- Hands-on experience with CI/CD tooling, including Git-based workflows, pipeline configuration, and automated build and deployment processes.
- Practical knowledge of Kubernetes and OpenShift for container orchestration, including Helm chart development and cluster management.
- Working knowledge of Linux administration and shell scripting to support automation, system configuration, and operational tasks.
- Experience delivering and managing software projects end-to-end, from planning and design through to testing and production deployment.
- Ability to work autonomously in a fast-paced environment, managing competing priorities and adapting to changing technical or business requirements.
- Bachelor's degree in a relevant field or equivalent practical experience.
Beneficial Skills & Qualifications
- Experience with AWS cloud services, including infrastructure provisioning, managed services, and cloud-native deployment patterns.
- Background in observability engineering, including setting up APM tools such as AppDynamics or Datadog to monitor application performance in production.
- Experience defining and measuring SLOs and SLIs for production services, translating reliability targets into actionable monitoring and alerting strategies.
