Staff React Engineer | Immediate Start | FTC | ASAP to May 2027

Our client, a leading technology business, is modernising a legacy CRM onto a recent React front-end, with AI capability being built directly into the platform. As Staff Engineer, you'll own the front-end architecture that gets it there.

The opportunity

You'll own how the new React app coexists with the legacy CRM during transition, things like iframe embedding, shared auth/session behaviour, and migration sequencing, while setting the technical direction multiple squads will follow, as AI-driven features get built into the product itself.

What you'll do

- Own front-end architecture for a major CRM modernisation effort, including AI-powered product capability
- Set component architecture, state management and testing standards across squads
- Make and own high-impact technical decisions on complex, multi-squad initiatives
- Define API contracts and integration standards with backend engineers (REST/GraphQL)
- Tackle the most ambiguous front-end problems no one else has untangled yet
- Mentor engineers and raise the technical bar across teams

What we're looking for





- Over 10 years in front-end development, React and TypeScript experience at scale
- Proven experience leading a front-end migration or rewrite that coexisted with a legacy system
- Track record of driving architectural decisions across teams, including through disagreement
- Strong hands-on use of agentic AI tools to boost developer productivity (coding assistants, AI-driven testing/debugging workflows)
- Comfortable shaping backend/API contracts even if front-end is your core specialism
- Solid grasp of SOLID principles, accessibility (WCAG) and performance at scale

Why this role

- Genuine Staff-level scope, architecture ownership, not just execution
- Ground-floor involvement in embedding AI into a live production platform
- Flexible working, home or Sydney/Brisbane offices, your call

Location & contract

Ideally based in Sydney or Brisbane, but not essential. Fixed-term contract until 31 May 2027. Candidates must be able to start before 1 September 2026, so immediate availability is preferred.
