Software Development Engineer III

Job description

Application close date: Applications will be accepted on an ongoing basis until the requisition is closed. 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! This role is part of Enterprise Technology (ET), where we’re developing the digital infrastructure needed to build the road to space, with an emphasis on digital capabilities required to advance Blue Origin’s mission. Enterprise Technology is the center of excellence for digital technology at Blue Origin, providing oversight and governance to align technology and business strategies. Software Development Engineer III – Platform Software Services (PSS) About the Role We're a team of collaborators, doers, and problem-solvers relentlessly committed to a culture of safety and innovation. This position will directly impact the history of space exploration and requires your dedication and keen attention to ensure safe and repeatable spaceflight. Join us in lowering the cost of access to space, fulfilling Blue Origin's vision of millions living and working in space to benefit Earth. As part of our Enterprise Technology (ET) team, you'll help build the digital infrastructure essential for the road to space. This is a platform engineering role — you'll be building the thing that builds the thing. We are looking for a skilled and motivated Software Development Engineer III to join our Platform Software Services (PSS) team, part of the Serenity Platform within Enterprise Technology. PSS owns and operates the business-critical backend services, APIs, and system integrations that power Blue Origin's core mission capabilities — spanning aerospace engineering, manufacturing, supply chain, mission operations, and beyond. You'll join a high-impact team that operates at the intersection of reliability and innovation, building the foundational platform layer that hundreds of engineers and business teams depend on every day. If you're passionate about building scalable, resilient backend systems and want your work to matter, this is your team. How We Build on PSS We build with an AI-assisted mindset — using tools like Claude Code, Cursor and other leading AI assistants to move faster, think bigger, and tackle harder problems. AI is a first-class part of how we design, develop, debug, and review software on PSS — not an afterthought. You'll be expected to adopt, evaluate, and advocate for AI tooling responsibly, with a clear eye on production reliability, security, and governance. The best engineers on our team don't just use AI — they know when to trust it, when to question it, and when to override it. Platform Scale & Impact PSS services power mission-critical workflows across engineering, manufacturing, supply chain, and mission operations — supporting hundreds of internal users and applications across Blue Origin. Our services handle high-throughput event processing, complex system integrations, and real-time data flows that teams across the company depend on around the clock. At this scale, reliability and scalability aren't aspirational — they're the baseline. The platform you help build directly determines how fast Blue Origin moves. What You'll Work With • Languages: Java, Python, JavaScript/TypeScript • Frontend: React • APIs & Messaging: REST, GraphQL, SQS, SNS, event-driven architectures • Cloud: AWS (DynamoDB, RDS, ECS, Lambda, S3, CloudWatch, and more) • Infrastructure & DevOps: Docker, Kubernetes, Terraform, CI/CD pipelines • Observability: Distributed tracing, centralized logging, metrics dashboards • Databases: Relational (PostgreSQL/RDS) and NoSQL (DynamoDB) • AI Tools: Claude Code, Cursor and equivalent AI-assisted development tools • Source Control & Collaboration: Git, code reviews, design reviews Key Responsibilities 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 Java and Python , following clean architecture and domain-driven design principles • 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 services such as DynamoDB, RDS, SQS, SNS, Lambda, ECS, and CloudWatch • 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 • Establish and uphold observability best practices including monitoring, alerting, logging, and distributed tracing Full-Stack & UI Contributions • Build and enhance web interfaces using React and modern JavaScript/TypeScript to deliver seamless user 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, Cursor 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,
