You’ll work alongside multidisciplinary teams of engineers, researchers, data scientists, and domain experts to rapidly transition cutting-edge technology into operational capability.

Key Responsibilities:

• Design, develop, and deploy advanced AI systems with reasoning and decision-making capabilities.
• Build and support LLM orchestration frameworks using technologies such as Lang Chain, Llama Index, Lang Graph, and emerging agentic AI platforms.
• Develop scalable MLOps infrastructure for model training, evaluation, deployment, governance, and monitoring.
• Create developer tooling, APIs, adapters, and interfaces for AI-native applications.
• Integrate multi-modal data sources including text, imagery, geospatial, sensor, and structured datasets into cohesive analytic pipelines.
• Implement retrieval-augmented generation (RAG), prompt engineering, and fine-tuning workflows.
• Scalable Infrastructure & Distributed Systems
  • Architect and develop cloud-native microservices and distributed systems supporting high-throughput workloads.
  • Build real-time streaming and event-driven platforms capable of processing large-scale data pipelines.
  • Design and optimize ETL/ELT workflows, data lakehouse architectures, and large-scale analytics systems.
  • Deploy and manage containerized applications using Docker and Kubernetes.
  • Support CI/CD pipelines, Infrastructure as Code (IaC), and automated deployment strategies.
  • Contribute to systems operating across secure, classified, and edge environments.
• Mission-Critical Engineering
  • Build resilient production systems with robust monitoring, logging, tracing, and observability.
  • Ensure software quality, security compliance, and ethical AI best practices.
  • Develop capabilities supporting geospatial analytics, time-series processing, and data fusion.
  • Troubleshoot and optimize performance across distributed applications and AI workloads.
  • Contribute to secure communications and fault-tolerant system architectures.
• Technical Leadership
  • Lead technical initiatives, architecture discussions, and engineering best practices.
  • Translate complex and ambiguous requirements into actionable engineering solutions.
  • Mentor engineers through code reviews, technical guidance, and collaborative problem-solving.
  • Help establish architectural standards, development workflows, and software quality practices.
  • Collaborate across engineering, research, operations, and stakeholder teams.
  • Support technical planning, roadmap development, and proposal efforts.

Required Qualifications:

• One of the following combinations of education and experience:
  • PhD with relevant software engineering experience
  • Master’s degree with progressive software engineering experience
  • Bachelor’s degree with substantial professional software engineering experience
  • Equivalent combination of education, technical training, and professional experience
