• Take proofs of concept through to completion, from hypothesis and prototype to a hardened, supportable production feature.
• Establish and evolve the front-end design system and component library.
• Build and consume REST APIs and define clear front-end/back-end contracts.
• Instrument applications for performance, error tracking, and usage analytics.
• Write and maintain automated tests (unit, component, integration, end-to-end).
• Package and deploy applications via Docker and Kubernetes using CI/CD pipelines.
• Provide technical mentorship on front-end practices and the responsible use of AI development tooling.

Required Qualifications

• Proven experience in Python development and REST API development.
• Minimum of 3 years of hands-on experience with Git-based source control and CI/CD pipelines.
• Minimum of 2 years of hands-on experience with containerized deployment (Docker, Kubernetes).

• Experience with cloud services, with AWS being preferred.
• Bachelor's degree in Computer Science, Engineering, or a related discipline.

Preferred Qualifications

• Experience with Django.
• Experience establishing or scaling a design system or shared component library.
• Experience with design tooling (Figma or equivalent) and AI-assisted design-to-code workflows.
• Experience with internal tools or platform engineering.
