What You'll Be Doing

Design and build AI-powered SDLC solutions, including code generation, automated code reviews, intelligent testing, and documentation.
Develop MCP-based tools and extensions that give AI systems access to relevant engineering context and tools.
Apply context engineering techniques to improve the accuracy, reliability,



and relevance of LLM-powered workflows.
Build LLM-integrated workflows across CI/CD pipelines.
Work with LLM orchestration, prompt engineering, structured outputs, and tool calling.
Develop and integrate RAG-based solutions using embeddings and vector databases.
Implement evaluation, observability, monitoring, and guardrails for AI systems.
Work closely with engineering and product teams to identify new opportunities for AI-driven automation and productivity.

What We're Looking For

5+ years of software engineering experience, ideally in backend or full-stack environments.
Strong programming experience with Java, Python, JavaScript, or Kotlin.
Hands-on experience integrating LLMs into software engineering or product workflows.
Good understanding of RAG, embeddings, vector databases, and LLM orchestration.
Experience with MCP, context engineering, or agentic workflows.
Solid understanding of soft
