Data & Architecture
•Design and optimize DynamoDB schemas for performance and scalability
•Work with time-series data in TimescaleDB and vector embeddings in Pinecone
•Build serverless workflows with AWS Step Functions
•Contribute to architectural decisions as the platform scales
Infrastructure & Integrations
•Write and maintain Infrastructure as Code using AWS CDK (TypeScript)
•Integrate third-party services (Stripe payments, video AI, search)
•Process and manage video files with FFmpeg and S3
•Build event-driven systems with Kinesis and Lambda
Security & Reliability
•Implement security best practices across backend systems
•Monitor performance with CloudWatch and resolve incidents
•Identify and address scalability risks proactively
Must Have Skills:
•4+ years of software engineering experience
•Extensive experience building scalable backend services specifically using Python and the FastAPI.
•Hands-on experience designing and deploying production-grade architectures using AWS and serverless architecture
•Experience with design and optimization of NoSQL (DynamoDB preferred) schemas for high-performance, large-scale applications.
•Solid experience managing cloud infrastructure using AWS CDK, or infrastructure as code
•Experience integrating complex third-party APIs. For example, for payment processing (Stripe) and identity management (Firebase Auth).
