Airflow Developer Jobs in Kennewick, WA (NOW HIRING)

PNNL’s AI & Data Analytics Division, part of the National Security Directorate, focuses on developing computational solutions for national security challenges.

We are seeking an exceptional Lead Software Engineer to architect and build next‑generation AI systems that span agentic AI platforms, large‑scale data orchestration, and real‑time intelligence processing.

Who You Are

An experienced engineer who bridges infrastructure, AI/ML, and production software. You have built highly scalable systems from scratch, led impactful initiatives, and turned complex problems into solutions. You are comfortable architecting distributed systems and fine‑tuning large language models.

What You’ll Build

• AI‑Native Systems: Agentic AI with dynamic reasoning, LLM orchestration, MLOps platforms, and multimodal reasoning pipelines
• Scalable Infrastructure: Microservices across security enclaves, real‑time streaming, petabyte‑scale ETL, data lake/mesh architectures, and Kubernetes/CI‑CD for classified & edge environments
• Production Systems: Secure AI deployments, observability across enclaves, ethical AI compliance, and geospatial/time‑series intelligence data fusion
• Technical Leadership: Lead engineers on high‑impact, ambiguous scope; drive architecture and strategy; build roadmaps from cutting‑edge research; mentor teams

What You Bring

• Engineering Leadership: Expert Python and another language (C#/.NET, Go, C++); experience establishing best practices, advanced CI/CD, and architecting distributed systems
• AI/ML Architecture: Production agentic AI experience; deep expertise with PyTorch/TensorFlow/JAX and LLM orchestration; LLM optimization and end‑to‑end ML platform design
• Cloud & Distributed Systems: Enterprise‑scale architecture across AWS/Azure/GCP; Docker, Kubernetes, IaC; event‑driven systems (Kafka, RabbitMQ); API design mastery; polyglot persistence
• Data Platform Engineering: Cloud‑native pipelines & orchestration (Airflow, Prefect); data lakehouse architectures; distributed computing (Spark, Flink, Ray); petabyte‑scale optimization and modern data formats
• Leadership & Communication: Mentoring teams, articulating strategy to executives, balancing delivery with technical excellence, and driving cross‑functional collaboration

What Makes This Role Unique

You will work at the intersection of cutting‑edge AI research and production engineering, building platforms that process the nation's most sensitive intelligence data while shaping technical strategy.

National Interest Project Examples
