Tech Customisation Engineer

Requirements:

• 7+ years of backend or full-stack engineering, with real experience adapting or localizing an existing product for a new market or region, not building greenfield.
• Comfortable reading and working within someone else's architecture rather than designing from scratch.
• Experience with configuration-driven or plugin/extension-based customization patterns, as distinct from forking a codebase.
• A genuinely detail-oriented documentation habit: this role's value is largely in the delta register being trustworthy, not just existing.
• AI-first, 10x mindset uses AI tooling to keep the delta register and customization work moving at 10x pace across two live sites, rather than tracking divergences by hand.

Nice-to-have:

• Prior work spanning multiple deployment sites or regions on a shared core product (e. g., multi-tenant or multi-country background).
• Comfort with git-based merge/rebase strategy for long-lived customized forks.
