Description
We are a fast-growing company at the forefront of engineering innovation and AI automation, seeking an experienced AI Engineer to help develop intelligent, scalable agentic systems integrated into modern software development lifecycles. This hands-on engineering role blends software development, AI experimentation, and product innovation. The successful candidate will play a key role in architecting agent-based systems, leveraging advanced frameworks such as LangChain and LlamaIndex, and deploying real-time AI capabilities integrated deeply with SDLC processes.
We also look favorably on candidates with:
- Experience designing RAG (Retrieval-Augmented Generation) or CAG systems using vector databases and hybrid retrieval techniques.
- Knowledge of LLM security challenges, including prompt injection and adversarial attacks.
- Familiarity with prompt evaluation frameworks and metrics such as truthfulness, helpfulness, and toxicity.
- Hands-on experience with developer-focused AI tools (e.g., Copilot, Cursor), including a deep understanding of their architecture and scalability.
