The Role
This is a hands-on Senior Frontend Engineering position within a team building next-generation AI-driven video forensic and evidence analysis tooling. You'll take real ownership of the user experience behind complex investigative workflows, video review, transcription, timeline analysis, streaming and AI-assisted insights.

* Write robust test coverage using Vitest and Playwright
* Optimise performance across bundle sizes, Core Web Vitals and query caching
* Review code and uphold strict TypeScript standards and security best practices
* Collaborate with product and design to take features from requirements through to production
What You'll Need
* Expert-level React with modern patterns across SPA applications
* Strong experience with modern build tools (Vite, Turbo, webpack) and monorepo management
* A pragmatic approach, you understand the trade-offs between abstraction and clarity
Nice to Have

* AWS CDK, Tailwind CSS, Shadcn/Radix components
* Zod validation and Playwright E2E testing
Why Apply
