Role Summary
We are looking for a Senior FullStack Engineer, AI to own and evolve Delta Exchange's suite of AI-powered products. You will work across multiple production AI applications: conversational support agents, RAG-powered search, code-generation copilots, and trading-strategy assistants. This is a hands-on role where you architect solutions around our existing stack, build retrieval pipelines, improve frontends with product sense, optimise inference costs, and run evaluations, collaborating closely with the product team.
Key Responsibilities
Design, build, and maintain production AI applications end-to-end: backend, frontend, and inference services.
Architect RAG systems using vector databases, embedding models, and chunking strategies optimised for accuracy and latency.
Build agentic workflows with tool/function calling, multi-step reasoning, and structured output parsing, with accuracy and control as priority.
Write and iterate on system prompts, few-shot examples, and prompt chains to maximise output quality.
Implement function calling, tool-use patterns,



and structured JSON/XML output handling using frontier and lightweight models from providers like Anthropic and OpenAI.
Drive cost optimisation: model selection, caching, token budgeting, and request batching at scale.
Build and maintain evaluation frameworks to measure accuracy, relevance, hallucination rates, and regression across prompt and model changes. Experience with observability tools (Sentry, Opik, etc.) is a must.
Work with message queues (RabbitMQ), caching layers (Redis), and relational databases (PostgreSQL) powering AI service backends.
Deploy and manage AI services on Kubernetes with CI/CD pipelines on AWS/GCP.
Integrate AI capabilities with third-party platforms (Telegram bots, chat widgets, etc.).
Contribute to architectural decisions: model selection, hosting (cloud APIs vs. self-hosted), and build-vs-buy trade-offs.
