Deliver high-quality backend services following Safe Agile Practices
Proactively identify and resolve issues with AI services, APIs, and model serving infrastructure.
Deploy comprehensive monitoring and alerting for backend AI systems, implementing auto-remediation where possible to ensure system availability and reliability.
Employ a security-first, testing, and automation strategy, adhering to backend engineering and MLOps best practices.
Collaborate with cross-functional teams, including data scientists, front-end engineers, data engineers, and business stakeholders, to understand requirements and deliver robust backend solutions.
Keep up with the latest trends and technologies, evaluating and recommending new tools, frameworks, and architectures to improve backend AI capabilities.

What You'll Bring:

Backend API Development (50%):

Design and develop robust, scalable RESTful APIs and GraphQL services for AI/ML applications.
Build backend services for LLM-powered applications, including RAG systems, document processing pipelines, and knowledge bases.
Implement secure API endpoints for model inference, prompt orchestration, and AI service integration.
Develop asynchronous processing workflows for long-running AI tasks (document analysis, batch predictions).
Create middleware and service layers to abstract complex AI functionality for front-end consumption.
Design and implement caching strategies, rate limiting, and API versioning for production AI services.
Build event-driven architectures using message queues (SQS, SNS, EventBridge) for scalable AI workflows.
Ensure APIs meet security, authentication, and authorization requirements for Federal environments.
Implement comprehensive error handling, logging, and observability for AI services.

MLOps & Infrastructure (30%)

Build and maintain ML model serving infrastructure using AWS SageMaker, Lambda, and containerized deployments.
Integrate AWS AI services (Bedrock, Textract, Comprehend) into backend pipelines and APIs.
Develop CI/CD pipelines for automated testing, deployment, and rollback of AI services.
Implement model versioning, A/B testing frameworks, and canary deployment patterns.
Create data preprocessing and feature engineering pipelines using PySpark and Databricks.
Build orchestration workflows for multi-step AI processes (ingestion → preprocessing → inference → post-processing).
Develop monitoring and alerting systems for model performance, latency, cost, and availability.
Collaborate with data scientists to produce ML models and transition from prototype to production.
Implement vector databases and semantic search capabilities for RAG architecture.
Manage prompt templates, model configurations, and AI service parameters as code.

Performance & Support (20%)

Optimize backend performance for high-throughput AI workloads and real-time inference.
Monitor and troubleshoot production issues including latency, errors, and cost optimization.
