AI Tech Lead (f/m/d)

Your mission

We’re looking for a Senior Technical Leader to define and drive the architecture of Juno – the agentic AI layer at the core of our platform. You are the central technical authority on how our agents are designed, orchestrated, and deployed at scale, making the hard architectural calls from multi-agent coordination patterns to production infrastructure. This is a deeply hands-on role: you’re in the code every day, prototyping new approaches, setting the bar for engineering quality, and solving systems problems. If you want to be the person who shapes how agentic AI actually works in production – not in theory – then this is the role for you.

How we work: Agentic-First Engineering
At JTL, AI-assisted development is not optional – it’s how we build. Engineers on our team actively use tools like GitHub Copilot, Claude Code, Cursor, or similar AI coding assistants as part of their daily work. We expect you to bring experience with these (or similar) tools.

Your responsibilities

• You own the end-to-end system architecture for agentic AI applications, from high-level design through production deployment and scaling to observability.
• You design and build multi-agent orchestration systems using frameworks such as LangChain, LangGraph, CrewAI, AutoGen, Semantic Kernel, or custom orchestration layers.
• You architect scalable, fault-tolerant backend services with Python (FastAPI, async patterns) and clean API contracts (REST, GraphQL, gRPC) used by internal teams and external clients.
• You implement cloud deployment strategies on Azure (AKS, Azure AI Services, Functions) or other clouds, including infrastructure-as-code, CI/CD pipelines, and cost control.
• You design integration patterns to connect agents securely and extensibly with external tools, APIs, databases, and enterprise systems.
• You establish architecture standards, design patterns, and engineering best practices for the AI engineering team (code quality, testing, security, documentation).
• You evaluate emerging agentic AI technologies, LLM providers, and tooling, and present technical recommendations and trade-off analyses to management.
• You mentor and develop junior and mid-level engineers through architecture reviews, code reviews, and knowledge-sharing sessions.

Your profile

• You have 8+ years of professional experience in software engineering, including at least 3 years in a senior, staff, or architect role with a focus on system design.
• You have expert-level Python skills: asyncio, FastAPI or equivalent async frameworks, Pydantic, dependency injection, and modern packaging (Poetry / uv).
• You have a strong track record in designing and building production APIs (REST, GraphQL, or gRPC) as well as event-driven / microservice architectures.
• You have hands-on experience building applications with agentic AI frameworks (LangChain, LangGraph, CrewAI, AutoGen, Semantic Kernel, or similar).
• You have in-depth knowledge of LLM integration patterns: prompt management, tool use / function calling, retrieval-augmented generation (RAG), vector stores (Pinecone, Weaviate, Qdrant, pgvector), and context-window optimization.
• You have experience with production cloud deployments on Azure: container orchestration (Kubernetes), serverless compute, networking, and infrastructure-as-code (Terraform, Pulumi, or CloudFormation).
• You have a solid understanding of distributed systems fundamentals: messaging (Kafka, RabbitMQ, SQS), caching (Redis), database selection, and observability (OpenTelemetry, Prometheus, Grafana).
• You have excellent communication skills and can convey complex architectural decisions to both technical and non-technical stakeholders.
