Software Engineer III Core Platform Software

Software Engineer III Core Platform Build scalable platform services powering enterprise workflows at Blue Origin's Serenity Platform.

Location: Seattle

Job Tags: Software

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.

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 Engineer III to join our Core Platform team within the Serenity Platform. Core Platform owns and operates the foundational layers that the rest of the company builds on — a centralized, managed API layer with shared data-model management, the event-driven messaging that moves data reliably between systems, the workflow-orchestration and business-rules engines that let behavior change through configuration rather than code, and the real-time data pipelines that tie it all together.

These layers span 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 platform layer that engineers and business teams across Blue Origin depend on every day. If you’re passionate about building scalable, resilient systems — and want your work to matter — this is your team.

We build with an AI-assisted mindset — using tools like Claude Code, Codex, 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 here — 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.

Core Platform services power mission-critical workflows across engineering, manufacturing, supply chain, and mission operations. 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. We’re also building the next generation of this platform — configurable workflow orchestration, data-driven business rules, and real-time data infrastructure for high-rate operations. 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.

• Languages:
  
  Go, Java, JavaScript/Type Script, 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)
