• Ensure application designs align with the broader architecture blueprint, integrating infrastructure and platform considerations into every build decision.
• Mentor and coach mid-level developers and analysts, providing technical direction and distributing work effectively across the team.
• Apply sound judgement when evaluating technical risk, ensuring solutions are compliant, secure, and aligned with applicable standards.

Required Qualifications & Skills

• Practical experience with relational and non-relational databases, including Oracle, SQL, and MongoDB.
• Cloud platform experience using OpenShift and Kubernetes, with working knowledge of build tools such as Gradle or Maven.

• Subject matter expertise in at least one core area of applications development, such as backend architecture, cloud infrastructure, or API design.
• Demonstrated ability to lead project delivery end-to-end, from planning through implementation.
• Master's degree in a relevant technical field.
• Clear and confident written and verbal communication skills, with the ability to translate technical concepts for varied audiences.
