Full Job Description

## Accountabilities Design and orchestrate end-to-end AI-driven workflows across the software development lifecycle, from requirements definition to deployment, operations, and continuous improvement. Architect agent-based systems that enable autonomous execution of engineering tasks, promoting an AI-first approach to software delivery. Build and evolve specialized AI agents for development, QA, DevOps, product management, and operational support functions. Define strategies for context management, prompt engineering, and token optimization to ensure efficient and reliable LLM performance. Structure and maintain knowledge bases, architectural decision records (ADRs), and technical documentation to ensure consistency and reuse across AI systems. Develop evaluation frameworks (Evals) to monitor agent quality, accuracy, and behavior, driving continuous improvement and reducing hallucinations. Ensure compliance with internal standards, security policies, and architectural governance across all AI-driven systems. Act as a technical reference for the evolution of AI platforms and multi-agent ecosystems applied to software engineering. Requirements: Strong background in Software Architecture, Platform Engineering, or Senior Software Engineering roles with enterprise-scale systems experience. Proven experience designing distributed systems, APIs, and microservices-based architectures. Hands-on experience with Agentic AI workflows, AI engineering, or applying LLMs within the software development lifecycle. Strong expertise in prompt engineering, context management, and optimization of LLM interactions. Ability to translate business logic and technical knowledge into structured workflows and agent-based heuristics. Solid understanding of observability, monitoring, and system behavior analysis in production environments. Experience with scalable system design and engineering best practices, including reliability and performance considerations. Strong analytical thinking, probl
