We’re looking for an experienced engineer to act as a technical steward for the Bank.Green website, our primary public-facing platform, working alongside another senior engineer already on the project. Technical decisions are made in a collaborative, consensus-driven way, vs. than top-down.
What difference will you make?
The platform serves roughly 5,000 pages, the majority of which are repeatable, programmatically generated bank profile pages built from shared templates and structured data. As a result, performance, caching, SEO, and build efficiency are key concerns.
This is a hands-on but flexible role, suited to someone who enjoys maintaining and improving real-world infrastructure that thousands of people rely on.
