Software Engineer III - Applied AI

Application close date:

At Blue Origin, we envision millions of people living and working in space for the benefit of Earth. We’re working to develop reusable, safe, and low-cost space vehicles and systems within a culture of safety, collaboration, and inclusion. Join our team of problem solvers as we add new chapters to the history of spaceflight! 

We are seeking a skilled and self-directed Software Engineer III - Applied AI to join our enterprise search and AI team. You'll take meaningful ownership over the architecture and delivery of agentic, workflow-driven search and discovery platforms - powering enterprise knowledge graphs and AI-assisted retrieval systems that help Blue Origin teams find critical data in seconds.
 

At this level, you will drive technical decisions, mentor junior engineers, lead cross-functional delivery, and bring rigor to the areas that matter most: retrieval quality, LLM evaluation, frontend engineering depth, and system observability. You will help mature the team's standards in these areas and set the example for how we build production-grade AI applications.
 

• Lead full-stack development of search, RAG (Retrieval-Augmented Generation), and agentic AI applications using Python, TypeScript/React, and Java
• Own retrieval pipeline quality: design and maintain evaluation harnesses for chunking strategies, embedding models, reranking, and end-to-end RAG response quality; drive improvements through offline and online evals
• Build and maintain LLM evaluation frameworks - including automated regression suites, human preference datasets, and task-specific benchmarks - to ensure consistent, trustworthy AI output
• Architect and deliver production-grade React frontends with deep component design, accessible UI patterns, state management (Redux, Zustand, or equivalent), and performance profiling
• Establish observability standards for AI systems: distributed tracing, structured logging, LLM-specific metrics (latency, token cost, hallucination rate, retrieval relevance), dashboards, and alerting
• Design and operate AWS-based infrastructure (ECS/EKS, Lambda, OpenSearch, S3, CloudWatch) using Infrastructure as Code (Terraform/CDK); champion DevOps practices including CI/CD, automated testing gates, and release management
• Collaborate with other engineers to integrate embedding models, vector databases, and reranking systems into production-ready pipelines
• Mentor junior engineers in engineering craft, testing discipline, and AI product quality
• Partner with product, design, and mission stakeholders to translate complex requirements into durable technical solutions
• Contribute to engineering standards, ADRs, and team knowledge bases

• Bachelor's degree in Computer Science, Software Engineering, or a related field
• 5+ years of software engineering experience, with demonstrated ownership of production systems
• Fluent with LLMs as a development tool - spec-driven development, and building AI-first features
• Hands-on experience building and maintaining LLM/RAG pipelines (from embedding and retrieval through reranking and prompt design) and evaluation frameworks (offline evals, regression testing, relevance scoring, hallucination detection)
• Strong frontend engineering skills: React (hooks, context, custom component libraries), TypeScript, state management, accessibility, and performance optimization
• Solid backend development in Python and/or Java; REST and GraphQL API design
• Experience with observability tooling: structured logging, distributed tracing (OpenTelemetry, X-Ray, or equivalent), metrics dashboards (CloudWatch, Datadog, Grafana), and alerting
• AWS cloud experience: ECS/EKS, Lambda, S3, OpenSearch, CloudWatch, IAM
• Familiarity with Infrastructure as Code (Terraform, CDK, or CloudFormation)
• Strong CI/CD practices: automated test gates, deployment pipelines, rollback strategies
• Excellent communication and cross-functional collaboration skills; ability to represent engineering decisions to non-technical stakeholders

• Experience with enterprise search platforms (Sinequa, Elasticsearch, OpenSearch)
• Knowledge graph or graph database experience (Neo4j, Amazon Neptune)
• AWS certification (Solutions Architect, Developer, or Machine Learning Specialty)
• Experience with agentic AI frameworks (LangChain, LlamaIndex, AutoGen, CrewAI)
• Background in AI system reliability engineering
• Familiarity with data visualization (D3.js, Plotly, Recharts) or 3D rendering (Three.js)
• Experience in aerospace, defense, or manufacturing industries
