Company:** FinDev Employment type: FULL_TIME

FinDev is looking for a Senior AI Engineer / AI Architect (Agentic Systems). We are seeking a strong engineer for an electronic trading project who knows how to build production AI systems and complex AI agents. This is not a vacancy for prompt engineering or developing simple chatbots. We primarily need a strong software engineer who has been deeply involved with LLMs for the past few years and knows how to design agentic systems, orchestration platforms, and robust AI infrastructure.

Responsibilities:

• Design and develop production AI agents and multi-agent systems.
• Build the orchestration layer: reasoning, tool calling, state management, workflows.
• Integrate LLMs with internal services, APIs, analytical systems, and data.
• Determine where an AI agent is needed and where a deterministic workflow is more reliable.
• Design distributed architecture: queues, retries, rate limiting, fault tolerance.
• Optimize LLM latency and cost: caching, model routing, parallel execution.
• Build evals, regression testing, and mechanisms to protect against hallucinations.
• Ensure auditability, explainability, and human-in-the-loop for AI systems.

Requirements:

• ✔ 8+ years of professional Software Engineering experience.
• ✔ Strong Python skills.
• ✔ 2+ years of hands-on experience with LLM systems in production.
• ✔ Real-world experience developing AI Agents, not just LLM integrations.
• ✔ Tool calling, orchestration, structured outputs.
• ✔ Strong System Design and Distributed Systems knowledge.
• ✔ Experience with production-grade architecture, scalability, and fault tolerance.
• ✔ Understanding of evaluation, hallucination mitigation, and reliability of LLM systems.
• ✔ English B2+.

Will be a significant plus:

• ➕ Multi-agent systems and agent orchestration.
• ➕ LangGraph, OpenAI Agents, or similar frameworks.
• ➕ MCP and RAG.
• ➕ Kafka / RabbitMQ / Redis.
• ➕ Docker and Kubernetes.
• ➕ Experience optimizing LLM inference latency and cost.
• ➕ Fintech, financial services, or electronic trading experience.

This vacancy is likely not suitable if your experience is primarily related to:

• prompt engineering and simple chatbots;
• Data Science / ML without a strong software engineering background;
• AI research without production experience;
• LLM API integrations without agentic systems;
• backend development without practical experience with modern LLMs.

What we offer:

• A complex project at the intersection of AI, distributed systems, and electronic trading.
• An international team of strong engineers.
• Fully remote work format.
• Locations: Poland, Portugal, Spain, Georgia.
• Relocation package.
