Staff Software Engineer

Your mission is to make DigitalZone's architecture hold together as the business multiplies. DZ has grown into several product verticals. With that growth comes drift: forked services, duplicated capabilities, and per-team divergence that quietly raises the cost of every future change. You will architect and deliver solutions that span multiple teams, drive convergence of shared services, and set the technical bar that other engineers work to. This is a multiplier role: your impact is measured by what several teams ship well, not by what you ship alone.

What you'll do
- Architect systems spanning multiple teams, anticipating future use cases and designing to minimise the cost of change rather than optimising for the current sprint.
- Drive convergence of shared services across business units, actively resisting fork-and-diverge, and reducing the drift .
- Set code quality, testing and review standards for your teams, including the conventions that make AI-assisted development safe at speed. Review for maintainability and system fit, not just correctness.
- Lead the difficult investigations: diagnose issues spanning your domain and adjacent ones, and mentor others on systematic debugging rather than solving it for them.
- Own observability for your domain and build a culture of it across teams, using both operational and business metrics to drive stability and performance work.
- Lead secure design reviews and partner with the security function to apply DZ's security strategy across your teams including how secrets and PII (passport and telecom identifiers) are handled to policy.
- Partner with fraud and risk stakeholders to build controls into your domain, balancing fraud loss and chargeback exposure against customer friction on a payment surface that carries real abuse exposure in different market.
- Ensure epics and cross-team dependencies are broken down, understood and resolvable without teams waiting on each other, and drive short cycle time.
- Mentor within and beyond your team, facilitate cross-team decisions with genuine buy-in, and decide engineering work for your teams based on strategy, contributing to org-level engineering strategy as it takes shape.
