AI/ML applications, including LLM-based tools, RAG architectures, or NLP
Backend service development using modern frameworks (e.g., Spring Boot), with REST API design, systems integration, and database interaction (relational and cloud-hosted)
Workflow automation platforms and BPM tooling (e.g., Camunda, BPMN process definitions), including audit instrumentation and notification services
Cloud platforms (AWS, Azure) for storage, compute, monitoring, and certificate management
Agile workflows, CI/CD pipelines (e.g., Jenkins), and rapid prototyping of internal software tools
Excellent written and verbal communication skills, with the ability to clearly convey complex technical information to a wide range of audiences.
Experience consolidating fragile, multi-step manual processes or legacy scripts into unified, automated software applications.
Demonstrated ability to bring industry knowledge of modern software practices to drive innovation within established teams.

Responsibilities

Providing software systems engineering skills to space, ground, and launch systems in the national security, civil, and commercial domains.
Designing and developing backend services and REST APIs that integrate with enterprise systems, cloud platforms, and data sources to deliver reliable, scalable solutions.
Building and maintaining data ingestion pipelines — including metadata extraction, content indexing, change detection, and automated job monitoring — that enable enterprise-wide search and data access.
Extending and enhancing workflow automation systems, including process definitions, business validation logic, audit logging, and notification services, to replace manual processes across the organization.
Identifying opportunities to adopt emerging technologies — including AI/ML and large language model applications — to solve existing organizational challenges and predict future needs.
Leveraging cloud platforms and modern tooling to replace brittle legacy systems with maintainable, automated solutions that reduce cross-system dependencies.
Collaborating with teams across the corporation to develop cross-domain solutions and engaging with customers to deliver software that addresses their most challenging problems.
