Collaborate with security, infrastructure, and operations teams to support compliant and reliable deployments.
Learn and apply enterprise architecture standards, secure development practices, and platform development guidelines.
Develop proficiency in Palantir Foundry development frameworks, ontology-driven application development, and enterprise data integration patterns.
Leverage modern development tools, including AI-assisted engineering tools where appropriate, to improve productivity and quality.
Continuously build technical knowledge in software engineering, data engineering, and platform-based application delivery.

Qualifications:

Bachelor’s Degree and minimum 4 years of prior relevant experience. Graduate Degree and a minimum of 2 years of prior related experience. In lieu of a degree, minimum of 8 years of prior related experience.

Preferred Additional Skills:

Experience developing software applications using modern programming languages such as Python, Java, TypeScript, JavaScript, or similar.
Experience with full stack software development, including frontend development, backend services, APIs, and data-driven applications.
Experience working with relational or non-relational databases, data transformation logic, and systems integration.
Understanding of software engineering best practices including version control, code reviews, unit testing, debugging, and CI/CD concepts.
Experience working in agile development environments and collaborating with cross-functional teams.
Strong problem-solving, communication, and teamwork skills.
