AI Native Software Developer

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 4 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
