Senior Software Engineer - Frontend UI

Role purpose

The Core Applications team is doing greenfield work, introducing new concepts and capabilities to our suite of UI products on a modern React + TypeScript stack.

As a Senior Software Engineer, you'll own significant portions of the codebase, drive technical decisions, and mentor fellow engineers. You'll collaborate closely with a distributed team across Australia and the US. This is a high-ownership role on a small, self-organizing team with direct visibility into a major product milestone.

How you contribute

• Build and ship features on the new agent desktop in React + TypeScript + Nx, using AI coding agents as part of the daily workflow.

• Review and approve pull requests and provide constructive feedback that raises overall application quality.

• Mentor fellow engineers and help set the technical bar for the team.

• Collaborate async-first with engineering, product, and design across distributed time zones.

• Contribute to architectural decisions and async planning via written documentation, Jira, and Confluence.

Skills, competencies and qualifications

Required:

• Strong React and TypeScript proficiency; experience with other modern frameworks (Vue, Angular, Svelte) is a good signal.

• Testing experience with Jest and/or Playwright, with an understanding of the value of thorough test coverage.

• Able to operate autonomously on a small, fast-paced team; fills gaps and makes reasonable calls without constant direction.

• Strong written communication and collaboration skills for a remote, async-first, distributed environment.

• Comfortable conducting code reviews, providing constructive feedback, and mentoring less experienced engineers.

• Prior experience using AI coding tools and a genuine willingness to evolve those skills as the space changes.

• Bachelor's degree (or equivalent) in a relevant discipline.

Desirable:

• Prior experience in CCaaS, agent desktop, or UI platform roles.

• Familiarity with TanStack Query and Zustand.

• Web accessibility knowledge; familiarity with WCAG standards and building accessible UIs.

• Monorepo and micro-frontend architecture experience; Nx preferred, but PNPM, Lerna, and other tools are good signals.

• Experience with WebSockets or real-time application development.

Other requirements

• Working shift must be aligned to overlap with Pacific working hours.

• This position requires the ability to be On Call.
