Job Description
Key Responsibilities:

Design and implement scalable web services and APIs to handle high request volumes, low latency, and strict reliability requirements.
Build and maintain frontend features in React and TypeScript, delivering robust, testable UIs connected to complex backend flows.
Own document ingestion and parsing pipelines, including OCR, structured extraction, schema mapping, and validation.
Lead LLM integrations: RAG pipelines, embeddings, prompt engineering, fine-tuning or adapters, hallucination mitigation, and evaluation.
Drive architectural decisions for data pipelines, inference infrastructure, caching, and retrieval at scale.
Mentor peers, lead code reviews, and improve engineering quality through observability, testing, and CI/CD.
Collaborate with product, data science, and operations teams to prioritize and ship high-impact features.


Required Skills & Qualifications:

Senior level. 8+ years of backend engineering experience, 5+ years of full-stack experience or equivalent working on a team with defined SDLC.
Strong Python backend experience (web frameworks such as FastAPI, Flask, or Django), and familiarity with async programming.
Experience building and operating high-volume web systems: load shaping, rate limiting, caching, and horizontal scaling.
Production experience with containers, Docker, Kubernetes, or serverless patterns, and cloud services (AWS, GCP, or Azure).
Strong systems design and debugging skills, with the ability to make tradeoffs for speed and reliability.
Clear communicator, collaborative with product and cross-functional teams.
Test-driven development, automated testing, CI/CD pipelines, and observability (metrics, logging, tracing).
Solid understanding of distributed systems, data consistency, error handling, and retries.
Demonstrated experience with LLMs and document parsing: retrieval-augmented generation, embeddings, vector databases, OCR libraries, and pipeline orchestration.
Professional experience with React and TypeScript building production UIs.


Nice to have:

Prior work in insurance or regulated industries; familiarity with policy documents, claims flows, and compliance constraints.
Experience with message queues (Kafka, RabbitMQ), workers (Celery), and ETL/data pipelines.
Knowledge of security and privacy considerations (PII handling, HIPAA, or SOC 2).
Familiarity with vector databases (Pinecone, Milvus, Weaviate) and embedding models.
Experience with LLM tooling and frameworks (LangChain, LlamaIndex, OpenAI/Anthropic SDKs, Hugging Face).
