Description

A Software Engineer in Palantir's Defense Applications team will marry Palantir's Foundry and AIP platform technologies with domain expertise to create exquisite domain-specific workflows and interfaces.

As an engineer on a defense application team, you'll be responsible for owning, not just executing, user-facing feature additions or enhancements. You'll spend time hands-on with customers and forward-deployed engineers to design solutions that not only meet the need but deliver value rapidly to support customers in ever-changing environments.

The dynamic nature of the defense applications teams make for, on average, shorter project cycles with high ownership at the individual contributor level but demand flexibility, practicality, and responsibility. The highly autonomous nature of teams means you will transition from mentee to mentor quickly as you build unique expertise in specific applications and features.

Palantir's engineering culture puts a premium on everyone having the skills and willingness to teach and learn, regardless of tenure. The best Palantir engineers form strong convictions quickly (to avoid analysis paralysis when every day counts) but hold them weakly, always ready to revise their opinion and update their world view when new ideas or additional data points are presented.

What We Value

  • Autodidacticism: we push boundaries and are constantly reinventing ourselves, you’ll never stop learning new things.
  • Collaboration: These are small teams solving hard problems, it only works when we pool our abilities and play off each person’s strengths.
  • Creativity and problem solving: You’ll be given objectives and goals, not blueprints and instructions.
  • Dependability: Palantir’s engineering culture is built on a foundation of trust and requires every developer to own their own outcomes and communicate proactively when confronted with the unexpected.

What We Require

  • 2+ years of frontend software engineering experience
  • Strong frontend coding skills: regardless of which frameworks you use or how you learned them, we're looking for people who can write 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
