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
