• Conduct unit, integration, and system testing of any code produced and projects contributed to, utilizing prior background and experience.

• Demonstrate high skill in programming language proficiency, with mastery in at least one primary language area.

• Write unit tests for test-driven implementations with minimal guidance.

• Exhibit skilled knowledge of database and data architectures, and how to securely access and incorporate them throughout the execution lifecycle of an application.

• Identify potential opportunities for code optimization.

• Provide input for code reviews and help with environment build deployment (local mockups and CI/CD), release notes, and build notices.

• Create any necessary development documentation as necessary, such as: use cases, user requirements, design specifications, technical specifications, process flows, data flow diagrams, sequence diagrams, communications diagrams, etc.

• Review code to proactively identify and mitigate potential issues and defects and help to identify sources of defects as well as troubleshoot various forms of code.

• Collaborate regularly with various peers in group settings across multiple divisions within CME Group to help produce applied examples of reference architectures and help establish the next generation of secure SDLC at CME Group through implementation projects.

What You'll Bring:

• A Bachelor's or Master's degree in Computer Science, Information Systems or other related field; or equivalent work experience.

• 6+ years of application development and/or infrastructure engineering experience.

• 2+ years of active hands-on experience with application deployments in the Cloud (AWS, GCP, Azure).

• Experience in using DevSecOps tools and frameworks for managing infrastructure as code like (or similar to) CloudFormation, Terraform, Chef, Puppet, Ansible, etc.

• Experience with DevSecOps tools such as Jenkins, Maven, Git, and Ansible.

• Experience working with containers and container systems such as Docker and Kubernetes.
