**Published:** October 1, 2026 - **Apply:** https://blueorigin.wd5.myworkdayjobs.com/BlueOrigin/job/Greater-Seattle-Area/Software-Engineer-III-Core-Platform_R72867 ## About the Role * Languages: Go, Java, JavaScript/TypeScript, Python * Frontend: React * APIs & Messaging: REST, GraphQL, NATS, event-driven architectures * Workflow & Rules: workflow-orchestration and business-rules / decision engines (orchestration and rules expressed as data, not code) * Cloud: AWS and cloud-native services * Infrastructure & DevOps: Docker, Kubernetes, Terraform, CI/CD pipelines * Observability: distributed tracing, centralized logging, metrics dashboards * Databases: relational (e.g., PostgreSQL) and NoSQL * AI Tools: Claude Code, Codex, and equivalent AI-assisted development tools * Source Control & Collaboration: Git, code reviews, design reviews, * 5+ years of professional experience in software development and production deployment. * Proficiency in at least one statically typed language (Go or Java) and one dynamically typed language (JavaScript/TypeScript or Python). * Strong foundations in computer science fundamentals - algorithms, data structures, distributed systems, and object-oriented design. * Proven track record of shipping production software end-to-end, from design through deployment and ongoing operations. * Hands-on experience with AWS services and cloud-native application development. * Working knowledge of REST and/or GraphQL API design and integration patterns. * Experience with asynchronous APIs and message brokers (e.g., NATS, Kafka, or similar), and designing API/event contracts consumed by other engineering teams. * Solid understanding of relational and NoSQL databases, including schema design and query optimization. * Experience with CI/CD pipelines, automated testing strategies (unit, integration, end-to-end), and deployment best practices. * Familiarity with containerization and orchestration tools such as Docker and Kubernetes. * Experience supporting production systems on-call, including incident response and postmortem practices. * Demonstrated habit of using AI-assisted development tools (such as Claude Code, Codex, or equivalent) as a core part of your engineering workflow - and the engineering judgment to know when to trust, question, or override what AI generates. * Strong communication skills - you can articulate complex technical concepts clearly, engage constructively in design discussions, and own outcomes. * Ability to deliver working solutions even with ambiguous or evolving requirements. * Must be a U.S. citizen or national, U.S. permanent resident (current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum., * Experience with workflow orchestration or business-process/rules engines and configuration-/data-driven system design - building systems where behavior is expressed as data rather than code. * Familiarity with event-driven architectures and asynchronous messaging patterns at scale. * Experience building real-time / event-streaming data systems. * Experience building or consuming GraphQL APIs, including schema design and federation concepts. * Frontend experience with React - component architecture, state management, and performance optimization. * Exposure to infrastructure-as-code tools such as Terraform or AWS CDK. * Experience with distributed tracing and observability platforms (e.g., Datadog, OpenTelemetry). * Experience extending or integrating commercial enterprise platforms (e.g., ERP, PLM, MES, or similar). * Experience integrating AI/LLM APIs (e.g., Claude, OpenAI, or similar) into backend services or platform workflows. * Familiarity with prompt engineering and understanding of how to apply generative AI responsibly within enterprise platform contexts. * Experience evaluating AI-generated code for correctness, security, and production readiness. * Track record of mentoring junior engineers through code reviews, design discussions, and technical guidance. * Experience in aerospace, manufacturing, or supply chain domains is a plus but not required. ## Description Platform Development & Architecture * Design, build, and operate scalable, highly available backend services and APIs that serve as the backbone of Blue Origin's enterprise platform. * Develop and own microservices and distributed system components using Go and Java, following clean architecture and domain-driven design principles. * Build and evolve the centralized, managed API layer and shared data-model management - designing API and event contracts that many teams depend on, with backward compatibility and versioning as primary constraints. * Build systems whose behavior is expressed as data, not hardcoded logic - configuration- and schema-driven workflows and decision tables that non-developers can change without a code deploy. * Architect robust integrations between internal systems and commercial platforms using REST, GraphQL, message queues, and event-driven patterns. * Propose and implement optimal technical architectures, presenting your designs clearly to peers and stakeholders. Cloud Infrastructure & Operations * Build and maintain cloud-native solutions on AWS, leveraging managed compute, storage, database, and networking services. * Develop and maintain infrastructure-as-code to support reliable, repeatable deployments across environments. * Own the reliability of your services - participate in on-call rotations, respond to incidents, conduct root cause analyses, and implement lasting fixes. These systems sit in the critical path of real operations, so uptime is non-negotiable. * Establish and uphold observability best practices including monitoring, alerting, logging, and distributed tracing. Real-Time Data & Full-Stack Contributions * Build real-time, event-driven data pipelines that ingest high-volume streams and serve both downstream systems and live dashboards. * Build and enhance web interfaces using React and modern JavaScript/TypeScript to deliver seamless experiences on top of platform services. * Collaborate with frontend engineers and designers to integrate APIs with user-facing applications efficiently and reliably. Engineering Excellence * Write well-tested, maintainable code and champion quality through code reviews, automated testing strategies, and CI/CD pipeline best practices. * Leverage AI-assisted development tools - including Claude Code, Codex, and equivalent AI assistants - to accelerate delivery, improve code quality, and explore smarter approaches to complex engineering problems. * Evaluate and thoughtfully integrate AI/LLM capabilities into platform services where they create measurable value - with a clear eye on reliability, security, and governance guardrails. * Identify and resolve complex software issues across the full stack - from service logic and database performance to deployment configuration and client integration. * Contribute to team standards, playbooks, and documentation that raise the technical bar across the team. Collaboration & Growth * Partner closely with Senior and Principal Engineers to deliver on the team's ambitious roadmap. * Work cross-functionally with product managers, business stakeholders, and engineers across the Serenity Platform to translate requirements into reliable platform capabilities. * Actively participate in design reviews, sprint ceremonies, and technical discussions - your voice and perspective matter here., 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.
