What You’ll Be Launching 

Seeking a Senior Python Engineer to design and deliver secure, scalable, high performance data processing and intelligent application platforms. This on site role (Washington DC–Baltimore area) requires deep expertise in Python, FastAPI, distributed event-driven systems, MongoDB, and in memory datastores such as Redis. The engineer will contribute to system design, build production-ready services and pipelines, and apply best practices across ingestion, transformation, streaming, AI integration, and secure delivery workflows. Experience with RAG systems and Agentic AI workflows is strongly preferred.

Your Mission (Should you choose to accept it)  

• Develop Python-based ETL frameworks, orchestration layers, and high-throughput data pipelines.


• Implement and optimize real-time, event-driven streaming architectures using Kafka and/or RabbitMQ.


• Build and scale FastAPI microservices with strong focus on performance, resilience, security, and observability.


• Design MongoDB schemas, indexing strategies, and aggregation pipelines with attention to performance.


• Implement caching layers, session management, and high-speed data access using Redis or similar in-memory stores.


• Contribute to the design and implementation of RAG pipelines, vector search integrations, and retrieval optimization.


• Implement Agentic AI workflows using LangChain and Crew AI.


• Apply Secure SDLC practices across coding, code review, CI/CD, and deployment.


• Participate in architecture reviews and contribute to engineering standards for distributed systems.


• Troubleshoot complex data, system, and performance issues in production environments.


• Support containerization, Kubernetes-native deployment patterns, and AWS cloud integrations.

Pre-flight Checklist
