Senior Palantir Foundry Developer

CommNet LLC is seeking a Senior Palantir Foundry Developer to support the Office of the Assistant Secretary of the Army for Acquisition, Logistics and Technology, ASA(ALT). This is a senior, hands-on individual-contributor position. The selected developer must be capable of independently designing, developing, troubleshooting, and delivering production solutions in Palantir Foundry. This is not an entry-level, training, general data analyst, project management, or advisory position. Candidates whose experience is limited to viewing dashboards, completing Foundry training, managing teams that used Foundry, or working alongside developers without personally performing the development will not meet the requirements. Responsibilities The Senior Palantir Foundry Developer will: Design, develop, configure, test, deploy, and maintain production solutions in Palantir Foundry. Design and maintain Foundry Ontology object types, properties, relationships, interfaces, actions, and supporting data models. Build operational applications, dashboards, forms, and workflows using Foundry Workshop. Develop and maintain datasets, pipelines, transformations, Functions, and application logic. Translate operational and business requirements into scalable technical solutions. Work directly with government customers, business users, data owners, and technical stakeholders to gather and refine requirements. Independently evaluate incomplete or changing requirements and recommend practical implementation approaches. Troubleshoot application, Ontology, permissions, data, transformation, synchronization, and workflow issues. Perform root-cause analysis and implement durable corrections rather than temporary workarounds. Enhance existing Foundry applications while minimizing disruption to current users and operational processes. Validate data quality, transformation results, application behavior, and user access. Document solution architecture, configuration decisions, dependencies, interfaces, deployment procedures, and changes. Participate in Agile planning, demonstrations, reviews, retrospectives, and iterative delivery activities. Explain technical constraints, risks, alternatives, and recommendations to both technical and nontechnical stakeholders. Take ownership of assigned capabilities from requirements development through production delivery and sustainment. Required Qualifications Applicants must meet all of the following requirements: Active DoD Secret security clearance at the time of application. United States citizenship. Five or more years of professional experience in software development, data engineering, enterprise application development, or a closely related technical discipline. At least two years of recent, hands-on Palantir Foundry development experience in a production environment. Demonstrated experience independently delivering substantial Foundry application capabilities. Demonstrated experience designing and maintaining Foundry Ontology object types, properties, relationships, and actions. Demonstrated experience building applications, dashboards, forms, and workflows in Foundry Workshop. Experience developing and maintaining Foundry datasets, pipelines, and transformations. Ability to explain specifically what you personally designed, configured, coded, tested, deployed, or repaired. Experience translating user or business requirements into implemented technical solutions. Experience troubleshooting existing Foundry applications across multiple technical layers. Ability to work independently without relying on another developer to design or complete core implementation tasks. Strong analytical and root-cause problem-solving skills. Strong written and verbal communication skills. Experience working directly with business users or customers to refine requirements and demonstrate solutions. Ability to operate effectively in a remote, cross-functional delivery environment. Ability to adapt quickly to evolving requirements, priorities, and customer needs. Preferred Qualifications The strongest candidates will also have experience with several of the following: Three or more years of hands-on Palantir Foundry development. Delivery of two or more production Foundry applications or major application capabilities. Foundry Pipeline Builder. Foundry Code Repositories. Foundry Functions. Foundry Action Types. Foundry interfaces and linked object models. Foundry Slate. Python development. TypeScript development. Dataset transformation development and testing. Data lineage, monitoring, validation, and failure recovery. Role-based access control and Foundry permissions. Enterprise data or operational workflow applications. Application performance analysis and optimization. Army, Department of Defense, or federal government programs. Agile software delivery. Working in an integrated prime contractor and subcontractor environment. Supporting customer demonstrations, technical reviews, and executive briefings. Documenting applications for sustainment, transition, and future development. A college degree is not required when the candidate can demonstrate the necessary technical experience and capability. What Success Looks Like Take an operational problem from initial discussion through a deployed Foundry solution. Develop an appropriate Ontology rather than simply using an existing object model. Build functional Workshop applications that support real business workflows. Understand how applications, Actions, Functions, Ontology objects, backing datasets, transformations, and permissions interact. Diagnose problems methodically across the application and data stack. Communicate effectively with both developers and operational users. Distinguish personal contributions from the accomplishments of the broader project team. Defend technical design choices and explain reasonable alternatives. Deliver working capabilities with limited technical supervision. Candidate Verification Process CommNet uses a skills-based evaluation process. Resume terminology alone will not determine whether a candidate advances. Candidates selected for consideration should expect: A verification interview focused on specific Foundry projects and the candidate’s individual contributions. A live technical discussion using a synthetic, unclassified Foundry scenario. Questions involving Ontology design, Workshop applications, forms, Actions, Functions, datasets, transformations, permissions, and troubleshooting. Follow-up questions based directly on claims made in the candidate’s resume and application responses. A customer-facing discussion evaluating communication, technical judgment, requirements analysis, and problem-solving ability. Verification of the candidate’s active security clearance. Candidates will not be asked to disclose classified information, proprietary source code, customer data, screenshots, or another employer’s confidential information. Generic descriptions of Foundry, memorized product terminology, unverifiable project claims, or answers that do not distinguish the applicant’s personal work from the work of the broader team will not advance. Application statements and resume claims must be supportable during a live technical discussion. Application Instructions Applicants should submit a resume that clearly identifies: The Palantir Foundry applications or capabilities they personally developed. The Foundry components they personally used. Their specific responsibilities on each project. Whether the solution was used in development, testing, or production. Their experience with Ontology, Workshop, Actions, Functions, datasets, transformations, Python, and TypeScript. The current status and level of their security clearance. Their earliest potential start date. Do not include classified information, proprietary code, customer-sensitive details, or confidential screenshots. Why CommNet LLC?
