Slingshot Aerospace is hiring a Platform Software Engineer

About the Role

Shape the foundation of a next-generation integration platform that powers mission-critical aerospace operations. As a Platform Software Engineer, you'll play a central role in designing and evolving a secure, multi-tenant system that connects diverse partners through robust APIs and real-time data workflows.

What You’ll Do

  • Lead architectural direction for APIs, event-driven services, and data pipelines, creating reference designs that guide long-term scalability.
  • Build and maintain high-throughput, low-latency systems with comprehensive observability, error resilience, and validation.
  • Design REST and GraphQL interfaces alongside event-based communication using Kafka, CloudEvents, and message queues.
  • Ensure platform compliance from inception, aligning with NIST 800-53, FedRAMP, and DoD Impact Levels, and contribute to authorization-to-operate documentation.
  • Develop and enhance the API Developer Hub, including lifecycle tooling, documentation, testing frameworks, and self-service onboarding.
  • Integrate third-party models and simulations—including AI/ML and space operations software—with standardized tooling and clear integration patterns.
  • Collaborate across engineering, security, product, and government stakeholders to deliver reliable, auditable systems.
  • Mentor team members on integration best practices, operational rigor, and sustainable development pace.

What We’re Looking For

  • 5+ years of software engineering experience focused on enterprise integration or API platforms, with at least 2 years leading architectural design.
  • Proven work with REST, GraphQL, event streaming (Kafka, queues), and contract testing.
  • Hands-on experience with AWS services including API Gateway, Lambda, and EKS, and infrastructure-as-code tools like Terraform or CDK.
  • Strong background in containerization (Docker, Kubernetes, Helm) and CI/CD pipelines using GitHub Actions or similar.
  • Proficiency in Java/Kotlin, Python, and working with PostgreSQL and MongoDB.
  • Experience implementing API security controls: rate limiting, secrets management, and key-based authentication.
  • Track record of deploying AI/ML or LLM features into production-grade APIs.

Nice to Have

  • Direct experience with federal compliance frameworks such as NIST 800-53, FedRAMP, or DoD ILs, especially in air-gapped or classified environments.
  • Background in fast-paced startups or product-driven organizations.
  • Familiarity with React for contributing to developer-facing frontend tools.
  • Collaboration with SRE and DevOps teams on observability, infrastructure tooling, and reliable deployments.
  • Experience testing integrations through contract and end-to-end test strategies.
  • Exposure to space, aerospace, or simulation technologies such as HLA/DIS.

Why This Work Matters

You’ll contribute to systems that support global security, disaster response, climate monitoring, and space operations. This role offers the chance to influence platform direction, work with government partners, and grow as a technical leader in an environment that values curiosity, initiative, and real-world impact.
