This is a Hybrid position; the candidate will be in the office (Reston, VA) 3 days a week.
What You’ll Do
Design and build microservices supporting the platform’s Sense → Predict → Orchestrate → Measure model
Integrate real-time data feeds (ATC, manifests, border processing, detection/security, kiosks, e-Gates) and contribute to the AI Detection Algorithm Marketplace
Build and operate adapters/connectors that normalize diverse source schemas (e.g., FIXM/AIXM, AODB, airline feeds) to a canonical event model
Deliver features like dynamic staffing allocation, lane management, passenger routing, and predictive maintenance
Develop calibrated predictive models (queue/wait, connection-miss, baggage, crowding, disruption propagation) and integrate LLM/RAG components for explanation and recommendation — keeping generative AI off the numeric prediction path
Work in an Agile/SAFe team with systems engineering, DevSecOps, and QA
Implement privacy-by-design and zero-trust controls (tokenization, policy-scoped access, data minimization, retention/expiry)
Write clean, tested code and use AI-assisted tools to speed development and improve quality
Support troubleshooting, performance tuning, and continuous improvement to reduce wait times and increase throughput
Implement modern automated testing strategies, including unit, integration, contract, end-to-end, and deterministic replay/backtesting
Minimum Qualifications
BS/BA degree and 5 years related experience OR Master’s with 2 years of related experience; 4 years of related experience in lieu of degree
Ability to obtain/maintain Public Trust; U.S. citizenship is required
Hands-on experience with microservices and at least one modern language (Java, Python, C++)
Experience with AI-assisted engineering tools and/or AI/ML-enabled systems
Experience with event-driven / streaming architectures (e.g., Kafka, Pub/Sub) and stream or batch data processing
Experience building and consuming APIs (REST/gRPC, OpenAPI/AsyncAPI) in distributed systems
Experience enhancing and maintaining existing software systems while preserving operational stability
Ability to navigate large, complex distributed systems and translate them into higher-level architecture
Agile experience; understanding of APIs and distributed systems
Preferred Qualifications
1 year software development experience supporting a related industry border/aviation customer (TSA, CBP/ICE, eu-LISA, Frontex, airport operators, airlines)
SAFe, Kafka/event streaming, cloud (AWS/Azure/GCP), Docker/Kubernetes, CI/CD, and DevSecOps experience
Stream processing (Apache Beam/Dataflow, Flink, or Spark) with windowing and out-of-order/late-data handling
Machine learning for tabular/time-series data (gradient-boosted trees, quantile/survival models) and model calibration/evaluation (Brier, pinball loss, AUC-PR)
MLOps: feature stores, model serving, model registry, and drift/skew monitoring (Vertex AI, Kubeflow, MLflow, or Feast)
LLM/RAG application development: embeddings, vector search (e.g., pgvector/FAISS/Qdrant/Vertex Vector Search), and model-gateway design
Infrastructure as Code (Terraform) and GCP-native services (GKE, Cloud Run, BigQuery, Firestore/Redis)
Zero-trust networking and privacy engineering (VPC/VPC-SC, mTLS, IAM, tokenization, consent/retention); familiarity with NIST 800-53, CMMC, or FedRAMP/ATO
Observability with OpenTelemetry (Cloud Logging/Monitoring/Trace or Grafana/Prometheus)
TypeScript/React for operator/traveler/executive experiences and real-time data visualization
Aviation/transport data standards (FAA SWIM, FIXM/AIXM, METAR/TAF) and simulation/queueing concepts
