Job description

Redwire is an innovative space and defense technology company driving advanced capabilities across the aerospace sector. We are looking for a leader who can contribute to concept of operations development, mission solution design, and strategic analysis for spacecraft programs supporting National Security Space. This includes work spanning space domain awareness, space resiliency, mission autonomy, structures, sensors, and next-generation space systems.
The Data Software Engineer serves as the technical authority responsible for architecting, scaling, and governing the graph-centric data infrastructure that powers the company's simulation, analytics, and digital-engineering ecosystems. This role blends backend engineering, high-performance data processing, and advanced graph-based modeling to ensure that data relationships, APIs, and integration workflows are coherent, scalable, secure, and aligned with mission and product objectives. You will design and optimize knowledge-graph schemas, build high-throughput data services in Python/C++/Rust, define robust data-access and governance patterns, and collaborate closely with simulation, systems engineering, frontend, and DevOps teams to deliver reliable, mission-critical data capabilities across aerospace, defense, and other regulated environments.
Major Responsibilities
  • Architect and scale knowledge-graph infrastructure supporting simulation, analytics, and digital-engineering workflows.
  • Design and optimize graph schemas for large, interconnected, and evolving data domains.
  • Develop high-throughput backend services in Python, C++, or Rust for data-intensive workloads.
  • Implement robust data-access layers including indexing, query optimization, and governance patterns.
  • Build and maintain secure APIs across REST, GraphQL, and gRPC ecosystems.
  • Ensure reliability and observability through logging, metrics, tracing, contract validation, and automated testing.
  • Collaborate across engineering teams to define clean integration boundaries and support mission-critical workflows.
  • Support CI/CD and DevOps integration for backend services and data pipelines.
  • Enforce secure data practices including authentication, authorization, secrets management, and encryption.

Ideal Experience
  • STEM foundation - Bachelor's degree in Computer Science, Engineering, Mathematics, or STEM related field, or equivalent experience.
  • Backend & data-service development - 1-5 years building backend systems, APIs, and data-driven services.
  • API design expertise - REST, GraphQL, schema design, versioning, and integration best practices.
  • High-performance backend programming - Python, C++, or Rust for distributed and performance-critical systems.
  • Database schema & modeling - Relational (PostgreSQL), graph (Neo4j), and document databases.
  • Data-access architecture - Indexing, query optimization, and governance for large-scale data domains.
  • Service reliability fundamentals - Observability, error handling, contract validation, automated testing.
  • API & data security - Authentication, authorization, secrets management, encryption.
  • CI/CD integration - Experience integrating backend services into CI/CD pipelines.
  • Cross-functional collaboration - Ability to work with simulation, systems engineering, frontend, and DevOps teams.

Desired Skills
  • Multi-protocol API development - REST, gRPC, SOAP, GraphQL.
  • Graph-based data modeling - Metadata lineage, digital-thread architectures, agent-reasoning structures.
  • High-throughput data APIs - Streaming systems, binary formats, performance tuning.
  • HPC-adjacent workflows - Simulation data, scientific computation, data-dense analytics.
  • Microservice architectures - Containerized deployments and service-to-service communication.
  • API design for diverse consumers - Interfaces for UIs, pipelines, and automated systems.
  • Regulated industry exposure - Aerospace, defense, or other high-integrity domains.
  • Open-source contributions - Backend frameworks, API libraries, database tooling, schema governance systems.
  • Security eligibility - U.S. Citizen; able to obtain and maintain DoD Secret clearance (TS/SCI preferred).
