Senior Frontend Engineer

Senior Frontend Engineer Engineering | Sydney, AU | Full-time - Hybrid Reports to: Piers Symons, COO & Co-Founder About Earlytrade Earlytrade is a B2B fintech company built for the construction industry. We help general contractors and subcontractors improve cash flow through a platform that gives subcontractors more control over when they get paid and on what terms. The result is a fairer, more transparent way to manage working capital across the construction supply chain. We’re building the product layer for workflows where trust is earned in seconds and lost just as fast. This is a role for someone who wants to turn complex financial and operational systems into software that feels fast, sharp, and decisive for real users making high-stakes decisions every day. The Role We’re hiring a Senior Frontend Engineer to own and evolve the product experience across Earlytrade’s customer-facing applications and shared frontend platform. This role sits at the intersection of product clarity, technical quality, and delivery speed: you’ll shape how complex financial and operational workflows are presented to users, while raising the bar on architecture, accessibility, consistency, and frontend craft across the stack. We’re looking for an engineer who takes ownership of the frontend from architecture to accessibility, raises the bar on code quality, and can evolve a mixed frontend estate with good judgment: strengthening what works, modernizing what doesn’t, and helping shape how the product grows.
