• Data Strategy & Infrastructure: Manage full-lifecycle deployments on AWS and Heroku. Optimize relational databases (PostgreSQL), design efficient schemas, and research advanced storage concepts (e.g. hashing, sharding) and distributed ETL processing.
• UI/UX & Product Collaboration: Partner closely with UI/UX designers and product owners to translate complex user workflows into responsive, intuitive web and desktop interfaces (utilising Tailwind CSS).
• Technical Leadership & Culture: Conduct deep-dive R&D, maintain high engineering standards through code reviews and continuous CI/CD improvement, and mentor team members via workshops and collaborative technical discussions.

ROLE REQUIREMENTS
