Senior Mobile Software Engineer

Senior Mobile Software Engineer at Braintrust for Taskrabbit

THIS IS ~3 MONTH CONTRACT. MUST BE ABLE TO OVERLAP 2-3 HOURS WITH PACIFIC TIME ZONE

Taskrabbit’s Tasker & Supply engineering team focuses on building and maintaining functionality to enhance Tasker’s experience of our platform. Our objective is to provide Taskers with a quality experience to better accept and complete jobs for their Clients.

In this project-based contract role, you will be brought on to accelerate a critical, high-visibility architectural migration: the implementation of our new Mobile Backend-for-Frontend (BFF), TanStack Query refactor, and GraphQL removal. Because 60-70% of this migration requires deep React Native refactoring, you will be pivotal in absorbing this integration load.

As a senior engineer, you'll be expected to dive in quickly, propose creative software-design solutions, and de-tangle the complex into the simple. We believe strongly in test-driven development and code reviews. You'll have the opportunity to work closely with multiple engineering teams and cross-functional partners to execute these deliverables. Join us in creating a better everyday life for everyday people. Join us in transforming lives one task at a time.

• Collaborating with design and product management to ensure the UI/UX remains flawless during the architectural swap

Qualifications
