This is a career-defining opportunity to play a crucial role in a hyper-scale AI company that is transforming the future of autonomous systems, energy, and the built environment.
As our Senior Applications Platform Engineer you'll join the Applications Platform team who are responsible for the shared application layer of Hive Controllers.

Build and maintain: Shared UI infrastructure, app-shell behaviour, layout systems, and reusable platform components.
Develop integration layers: Between frontend applications, cloud services, Hive workflows, and hardware/domain models.
Improve: Reliability, maintainability, and developer velocity across the monorepo.
Drive: Technical design, debugging, code review, and architectural cleanup for cross-cutting systems.
Partner with: Product, design, cloud, and hardware teams to deliver coherent end-to-end solutions.
Mentor: Engineers and help raise the team's standards for quality, testing, and technical decision-making.
