What will I be doing?

• Own and evolve the architecture of Fin's web platform.


• Define the long-term technical strategy for the web team, focusing on scalability, performance, developer productivity, observability, and system reliability.


• Collaborate closely with marketing, design, analytics, and data science stakeholders to ensure the platform supports their goals with accuracy, performance, and agility.


• Lead and influence the design and implementation of MarTech systems for event tracking, attribution, funnel reporting, A/B testing infrastructure, and more.


• Partner with engineers across web, infrastructure, and data to create a high-quality, cohesive technical ecosystem.


• Mentor and elevate engineers across the team and organisation - providing guidance on architecture, data modeling, system design, and engineering best practices.


• Set the standard for technical excellence in reliability, maintainability, code quality, and operational readiness.


• Provide technical leadership and insight to Engineering Managers, Product Managers, and executive stakeholders - communicating risks, trade-offs, and opportunities clearly.

• Experience in a high-scale growth-focused web environment.

• Strong understanding of web analytics and data instrumentation - experience with event tracking SDKs, Google Tag Manager, or similar.


• Comfortable working in and supporting full-stack codebases - even if this role is not UI-heavy, a solid frontend architecture awareness is valued.
