Job description

A World-Changing Company

Palantir builds the world’s leading software for data-driven decisions and operations. By bringing the right data to the people who need it, our platforms empower our partners to develop lifesaving drugs, forecast supply chain disruptions, locate missing children, and more.

The Role

Palantir Foundry is an end-to-end platform for data-driven decision-making. We're transforming the way organisations securely integrate their data, so they can then build reliable, critical applications atop that unified foundation. Our customers use Foundry to perform rich analyses that drive core operations within their organisations. They can also build sophisticated, full‑fledged programs, such as common operating pictures, alert‑triaging inboxes, and resource allocation planning tools driven by rich‑ML models.

As a Full Stack Engineer focused on application development in Foundry, you will be responsible for crafting the tools used by thousands of users to build the sophisticated applications that power their businesses. You will architect and develop interfaces, state management, and access patterns to support data-intensive workflows that are both powerful and approachable. You may spend one day interviewing users to better understand their needs and identifying product gaps to improve, and the next day reviewing customer context and brainstorming approaches to handling intricate UX needs with your teammates.

You’ll regularly be faced with sophisticated technical problems, requiring you to scope out the solution design and find an incremental path to shipping the new features. As part of this, you will own APIs and schemas that power your frontend code, or work with other backend engineers to develop them together.

We're hiring engineers who are passionate about solving real-world problems and empowering both customer app builders and end-users to do their work optimally.

Frontline

Foundry Software Engineers may be offered the opportunity to Frontline, an exclusive program unlike any other. This unique, short-term assignment involves being embedded with customers, allowing you to work directly with users and gain firsthand insight into how our products are used and the challenges our customers face. Frontliners operate across a broad spectrum of responsibilities, much like a startup CTO. They work in small teams to own the end-to-end execution of high‑stakes projects, from architecture and building custom web apps to conducting workshops and strategizing with executives. No two days are alike, and the experience feeds directly back into our development process, helping to refine and enhance our products.

Core Responsibilities

• Working as part of a community of engineers building shared frontend tooling to enable teams across Foundry
• Designing and building high‑scale data‑intensive APIs
• Developing interactive workflow UIs
• Building products that make technical concepts accessible for non‑technical users
• Creating low‑code/no‑code WYSIWYG tools that enable application builders within Foundry to build products for their users

Technologies We Use

• Typescript, React, and GraphQL are central to our frontend development.
• Blueprint as a reusable front‑end component library.
• A combination of open-source and internal technologies that suit the problems at hand.
• Industry‑standard build tooling, including Gradle, Webpack, GitHub, and CircleCI.

What We Value

• Passion for improving user workflows and building user interfaces that enable users to tackle their problems while maintaining engineering quality.
• Ability to work collaboratively in teams of technical and non‑technical individuals and understand how technical decisions impact users.
• Skill and comfort working in a constantly evolving environment with dynamic objectives and iteration with users.
• Experience brainstorming and iterating with product designers.
• Experience building high‑quality software in a fast‑paced CI/CD development environment.
• Proven ability to learn continuously, work independently, and make decisions with minimal supervision.
• Ability to learn new technology and concepts, even without in-depth experience.
• Active UK Security clearance, or eligibility and willingness to obtain a UK Security clearance is beneficial but not necessary.

What We Require

• 2+ years of frontend software engineering experience.
• Strong frontend coding skills using clean, effective code, regardless of framework, and existing proficiency in JavaScript with an understanding of web technologies.
• Familiarity with data structures, loading patterns, frontend frameworks, and other technical tools and concepts.
• Proficiency with programming languages such as JavaScript/TypeScript or similar.
• Strong written and verbal communication skills.
