AI engineer

Role - AI engineer
Location: Phoenix, AZ (Onsite)
Fulltime

Must Have Technical/Functional Skills

• 10+ years of experience building large-scale distributed systems + strong experience with LLM systems, agentic workflows or advanced ML infrastructure
• AI engineers with recent NodeJS/Javascript/Typescript experience
• Proven ownership of complex, cross-cutting agentic systems spanning multiple teams or products.
• Strong engineering fundamentals across backend systems, APIs, data pipelines, and cloud infrastructure.
• Deep experience across the agentic AI stack, including planning, tool use, memory, and evaluation.
• Fluency with AI-assisted and agentic development workflows.
• Comfort operating in ambiguous problem spaces and translating them into shipped, reliable autonomous systems.
• Ability to influence technical direction and align teams without formal authority.
• Experience in workflow engines, async processing, queues, and streaming systems.
• Languages: NodeJS/Javascript/Typescript,Python, Go
• APIs and services: REST, gRPC
• Cloud and infrastructure: AWS and/or GCP, Kubernetes
• Distributed systems: event-driven architectures, including Kafka
• Orchestration Frameworks: LangGraph, LangChain, AirFlow, etc
• Integration of commercial and open-source LLMs into agentic workflows
• Agent and orchestration frameworks such as LangChain, LlamaIndex, Semantic Kernel, or CrewAI, with strong judgment about when to use frameworks versus building lighter-weight primitives
• Model-level work using PyTorch and the Hugging Face ecosystem (embeddings, fine-tuning, inference tooling), with some exposure to TensorFlow
• Strong schema, validation, and state management practices using tools such as Pydantic (Python) and Zod (TypeScript)
• Experience building agentic systems in fintech or other regulated industries.
• Experience as a founding engineer or early technical leader in AI-driven products.
• Demonstrated success delivering technically complex autonomous systems that customers actively rely on.
• Meaningful contributions to open-source AI or agentic frameworks.
• Familiarity with fine-tuning, model optimization and inference pipelines is a plus.

Roles & Responsibilities
• Drive technical direction for agentic AI initiatives, influencing architecture patterns, autonomy boundaries, and system design.
• Design, build, and operate production-grade age ntic AI systems used across multiple products.
• Own and evolve shared agentic AI capabilities, including:
• Agent frameworks and orchestration layers
• Planning, tool use, and memory strategies
• Retrieval and grounding (RAG) pipelines
• LLM infrastructure, inference, and model gateways
• Evaluation, observability, and safety tooling for autonomous systems
• Lead technical design reviews and help teams navigate tradeoffs involving autonomy, safety, reliability, scalability, and cost.
• Partner across teams to deliver complex, cross-cutting agentic AI initiatives from concept to production.
• Evaluate emerging models, techniques, and agentic patterns and translate them into practical, enterprise-ready improvements.
• Mentor senior engineers and raise the technical bar for agentic AI development through example and influence.
