Senior Python / Gen AI Backend Engineer

Apply directly at VotersAI website (https://votersai.com/careers), a silicon valley, USA based start-up building a patent-pending, multi-tenant intelligence platform on AWS. We are hiring a senior Python engineer with generative-AI experience to build our serverless backend and AI features across our data and messaging systems.

What you will do

• Build production Python services on AWS Lambda: data filtering and query services, email and SMS/MMS messaging pipelines, scheduling, and high-throughput sync and ingest consumers.
• Build generative-AI features on AWS Bedrock (Claude) and comparable LLM APIs: real-time content classification and moderation, retrieval-augmented generation, and LLM-driven workflows.
• Work across three data planes: DynamoDB (NoSQL), Amazon RDS PostgreSQL (relational), and ClickHouse (analytics) — modeling, querying, and optimizing each.
• Design and document REST APIs on API Gateway and integrate third-party APIs (messaging, email, payments, data vendors).
• Engineer for correctness and scale: strict multi-tenant data isolation, idempotency and deduplication, and high concurrency.

Required experience

• Minimum 5 years of professional backend engineering experience is required; expert in Python (3.12+) and production AWS Lambda / serverless (boto3).
• Demonstrated generative-AI / LLM application experience: AWS Bedrock or the Anthropic / OpenAI APIs — prompt engineering, few-shot design, tool and function calling, retrieval-augmented generation, and evaluation of model output.
• Strong in BOTH NoSQL and relational databases: DynamoDB (single-table design, GSIs) AND PostgreSQL (schema design, complex SQL, transactions).
• REST API design and implementation behind API Gateway; integrating third-party APIs. Testing and version-control discipline.

Preferred

• ClickHouse or other OLAP / columnar analytics; large-scale query optimization.
• Vector stores and embeddings; retrieval-augmented generation over mixed structured and unstructured data.
• Model Context Protocol (MCP).
• Geospatial work (routing, Mapbox); multi-tenant SaaS; political-technology or regulated-communications experience.
• You will be working on patent pending technology. Strong Math background preferred.Location: Pune India
