Agentic Systems Engineer

Requirements

• A mindset that sees AI not as a tool, but as a new execution layer. You design systems where agents act, validate, and evolve software - not just assist humans.
• Proven experience integrating LLMs, MCP servers, and multi-agent systems into real engineering workflows - not experiments, but production-oriented pipelines.
• Hands-on work with frontier models such as Claude Opus 4.x, GPT-5.x Codex or similar - using them for structured reasoning, code generation, validation, orchestration, and system design.
• Strong understanding of context engineering and token economics - including prompt architecture, reusable memory patterns, retrieval layers (RAG), persistent state management, and optimizing token consumption for long-horizon agent workflows.
• Ability to design guardrails for autonomous systems - validation layers, policy enforcement, compliance checks, circuit breakers, and architectural constraints that keep AI-driven systems stable and safe.
• 4+ years of strong Java (Spring/Spring Boot) or Kotlin experience in production environments - enabling you to validate, constrain, and refine what AI agents generate.
• Deep understanding of distributed systems and scalable backend architectures in high-throughput, low-latency environments.
• Experience designing resilient microservices capable of operating under financial-grade reliability and regulatory requirements.
• Comfort building observable, introspectable, automation-friendly systems - because agents cannot safely operate opaque services.
• Strong communication skills to collaborate effectively in a global AI-first organization where engineering, data, compliance, and product intersect.
