Process heterogeneous sensor data for real-time state estimation and threat detection, integrate sensors and effectors, build LLM/AI-driven decision systems, and engineer scalable, reliable, fail-safe solutions for tactical and operational missions while collaborating with multidisciplinary teams.

Contribute production-quality code to Palantir products (Gotham, Foundry, Apollo) across the full product lifecycle. Collaborate with engineers, PMs, designers, and users; prototype, implement, and ship features. Learn on the job with mentorship and opportunities to engage directly with customers to understand real-world use cases.

Join Palantir Production Infrastructure to build and operate large-scale platforms (Rubix, Apollo) and core deployment, observability, and Kubernetes-based PaaS tooling. Own full product lifecycle, collaborate with cross-functional teams, and deploy software supporting civil and defense customers while learning from a paired mentor.

Develop and ship production-quality software for Palantir's Gotham defense product. Work across the product lifecycle on features like geospatial tools and release infrastructure, collaborate with cross-functional teams, and be mentored while contributing code and prototypes to mission-critical systems.

Build and ship scalable software for Palantir Gotham across the full product lifecycle. Collaborate with cross-functional teams, work directly with users to understand problems, and contribute high-quality code while paired with a mentor. May involve field visits to customers to learn mission needs.

Interns contribute production infrastructure code across deployment, observability, and environment platforms (Kubernetes PaaS, Apollo, Rubix). Paired with a mentor, they design, implement, and ship features, collaborate with cross-functional teams, and may observe field deployments with government or defense partners.

Develop, integrate, and field autonomy software for expeditionary unmanned aircraft (V-BAT/X-BAT). Own features from software-in-the-loop to live flight tests, collaborate with aircraft and perception teams, lead technical integration, support field deployments and mission testing, and troubleshoot hardware/software issues.

Develop, integrate, and field autonomy capabilities for novel platforms (space, maritime, unmanned helicopters). Own end-to-end integration from software- and hardware-in-the-loop to live tests, partner with platform and cross-functional teams, support on-site testing, debug hardware/software issues, document designs, and improve integration and testing processes.

Lead technical strategy and engineering for autonomy on new platforms (space, maritime, contested logistics). Define architecture, guide development and integration, mentor senior engineers, support testing and deployments, resolve complex hardware/software integration issues, and transition R&D into operational programs.

Develop, integrate, and field autonomy software for launched effects platforms, owning features from design through live flight testing. Drive technical execution, collaborate with autonomy, perception, and vendor teams, support system bring-up and field operations, and implement C2 interoperability and deployment processes. Travel to tests and customer exercises to support mission execution and debugging.

Lead technical delivery and integration of autonomy software for launched effects, including autopilot integration, multi-agent coordination, and fleet-scale deployments.
