Job Description:

Palantir builds applications that help customers organize, understand, and make decisions based on their data. Because these applications serve different roles within an organization's workflow, users frequently have multiple applications open at once, and expect them to work together seamlessly. While backend services handle much of this coordination, delivering a truly fast and responsive experience requires applications to also directly interact with each other through client-side frameworks running in the browser. Building these frameworks is uniquely challenging: every Palantir application plays a distinct role and has its own set of first-class UX concepts, yet the frameworks need to integrate cleanly into all of them. Success requires both strong API design skills and a keen eye for user experience.

Job Responsibility:

Work with cross-application frameworks end-to-end, from low-level technical implementation to high-level UX decisions
Work extensively with core web APIs (Broadcast Channels, Service Workers, Local Storage) to enable real-time communication between applications
Help develop an Electron application that extends and enhances these workflows through Electron-specific capabilities
Build relationships with teams across the company and develop a deep understanding of different codebases and their architectural patterns
API design: create interfaces that are ergonomic, portable, and powerful enough to enable complex user interactions

Requirements:

2+ years of frontend software engineering experience
Strong frontend coding skills: clean, effective code with proficiency in JavaScript and an understanding of how web technologies work
Bachelor's degree in Computer Science or related field, or equivalent understanding of algorithms, performance, and systems design
Strong written and verbal communication skills
Eligibility and willingness to obtain a US Security clearance

Nice to have:

Passion for collaborating across teams and quickly ramping up on unfamiliar codebases
Creative problem-solving skills and excitement about designing novel user interactions
Experience building high-quality software in a fast-paced CI/CD development environment
Ability to ramp up quickly and autonomously
willingness to learn continuously, work independently, and make decisions with minimal supervision
Drive to unlock and improve user workflows while maintaining engineering quality
