Preferred * Lakehouse platforms (Databricks, Spark, Delta Lake, Unity Catalog) * Knowledge graphs (Neo4j, Neptune) * Enterprise search (Sinequa, OpenSearch) * Natural-language-to-SQL * AI observability, inference cost and latency optimization * Multi-modal AI over documents, imagery, or telemetry * Graduate degree or published open-source work in applied AI ## Description We are looking for a Principal Software Engineer to set the technical direction for how Blue Origin finds, reasons over, and acts on its enterprise knowledge. As a senior individual contributor, you'll own the architecture of our agentic AI platform - the lakehouse, knowledge graph, retrieval systems, and natural-language interfaces that help engineering, manufacturing, and mission teams find critical data in seconds, not days. You'll lead through technical credibility, not reporting authority - staying hands-on, writing production code, and proving out the hard parts yourself. Your impact is enterprise-wide. Your work reaches engineers designing engines, technicians building vehicles, quality teams investigating anomalies, and mission teams in flight, and is increasingly reused by other products through shared APIs and MCPs. 2. Responsibilities * Own the architecture and roadmap for Blue Origin's agentic AI, retrieval, and semantic reasoning platform. * Stay hands-on across the full stack - write production code, build reference implementations, and prove out the hard parts yourself rather than delegating and reviewing. * Design shared capabilities for reuse - exposed through documented APIs and MCPs - so other teams and products adopt them instead of rebuilding data and AI foundations. * Set architecture direction across the platform portfolio (ingestion, knowledge graph, enterprise search, natural-language-to-SQL, multi-modal evidence), establishing reusable patterns and CI/CD, IaC, and release standards. * Mentor senior / mid-level engineers and steward the standards, ADRs, and reference implementations that raise the whole team's bar. * Establish AI evaluation and observability as engineering disciplines: regression suites, accuracy thresholds, and release gates, plus tracing and metrics (latency, cost, hallucination rate, relevance) on every production surface. * Make AI output defensible - set the standard that answers trace to source-grounded evidence with provenance, access control, and confidence, and drive retrieval and generation quality through offline and online evaluation., Applicants for employment at Blue Origin must be a U.S. citizen or national, U.S. permanent resident (i.e. current Green Card holder), or lawfully admitted into the U.S.as a refugee or granted asylum. Background Check * Required for all positions: Blue's Standard Background Check * Required for Certain Job Profiles: Defense Biometric Identification System (DBIDS) background check if at any time the role requires one to be on a military installation * Required for Certain Job Profiles: Drivers who operate Commercial Motor Vehicles with a Gross Vehicle Weight (GVW), Gross Vehicle Weight Rating (GVWR) or combination of power unit and trailer that meets or exceeds 10,001 lbs. and/or transports placardable amounts of hazardous materials by ground in any vehicle on a public road while in commerce, may be subject to additional Federal Motor Carrier Safety Regulations including: Driver Qualification Files, Medical Certification (obtained before onboarding), Road Test, Hours of Service, Drug and Alcohol Testing, vehicle inspection requirements, CDL requirements (if applicable) and hazardous materials transportation/shipping training. * Required for certain Job Profiles: Ability to obtain and maintain Merchant Mariner Credential, which includes pre-employment and random drug testing as well as DOT physical
