Palantir Foundry Developers

Palantir Foundry Developer (Contract – 6–12 Months) . . 

Seeking Palantir Developers for large-scale enterprise transformation built on Palantir Foundry, centered on the Unified Data Layer (UDL) platform. The platform consolidates data from hundreds of disparate source systems (including 30+ ERPs and operational databases) to deliver authoritative program performance visibility across schedule, cost, earned value, financial, material, and operational data.

The environment is business-led, executive-facing, and highly iterative. Requirements evolve rapidly as business leaders shape direction. Contractors will work under  IT leadership, integrated into existing agile sprints, and are expected to produce visible, usable outputs from the first sprint.

•        Partner closely with backend engineers, product owners, and business stakeholders to deliver tangible progress that executives can see and react to

•        Improve the usability and clarity of business applications without waiting for perfect functional specifications

•        Contribute to frontend standards, component reuse, and documentation where it supports team velocity

Required

•        3+ years of backend engineering experience in production data environments

•        Ability to work effectively with ambiguity, incomplete requirements, and rapidly shifting priorities; Mature, autonomous working style with strong professional judgment
