Job description


Position Summary
The Senior AI Engineer, Agentic Systems (Python/React/AWS/AI) will design, build, deploy, and operate production-grade agentic AI systems that support enterprise-scale use cases. The role emphasizes shipped production experience, system reliability, orchestration, monitoring, debugging, and the ability to expose enterprise capabilities as tools or skills for LLM-powered agents.
Core Responsibilities
  • Build and operate production agentic AI systems, including deployed, monitored, and debugged agents running at scale.

  • Own agentic use cases end-to-end, partnering directly with business stakeholders from problem definition through delivery and operational support.

  • Design orchestration patterns for autonomous or semi-autonomous agents using modern agent frameworks and production orchestration layers.

  • Develop enterprise capabilities as tools or skills for LLMs, enabling agents to interact with business systems and workflows in a controlled, scalable way.

  • Engineer reliable backend services for agentic workloads, with emphasis on Python-based development and integration with Java service layers where required.

  • Implement and support production infrastructure for AI workloads, including environments where Kubernetes and model-serving components such as vLLM may be part of the stack.

  • Evaluate and communicate system failure modes, including the ability to walk through shipped systems, operational issues, debugging approaches, and mitigation strategies.

  • Collaborate with vendor, engineering, and business teams to deliver solutions with limited ramp-up time, consistent with expectations for senior contract engineering talent.

  • Maintain a production-first engineering standard, ensuring the role does not over-index on framework familiarity at the expense of real deployment experience.

Required Qualifications
  • 7+ years of software engineering experience, with demonstrated experience building and shipping production systems.

  • Hands-on production experience with agentic AI or GenAI applications, including deployment, monitoring, debugging, and operating agents at scale.

  • Comfortable in a senior contract delivery model where the expectation is faster delivery and limited ramp-up investment.

  • Core expectations (must have exposure across all):

  • Software engineering: Proficiency in Python (preferred) or Java, with solid fundamentals (clean coding, testing, APIs, debugging, performance, and maintainability).

  • Cloud engineering: Working knowledge of at least one public cloud provider-AWS preferred-including hands-on familiarity with deploying/running services, IAM/security basics, logging/monitoring, and common managed services.

  • AI/ML exposure: Practical exposure to AI/ML concepts and workflows (e.g., model integration patterns, basic ML lifecycle understanding, evaluation basics), sufficient to ramp into agent development with minimal hand-holding.

  • Preferred experience (strong differentiators):

  • Hands-on experience integrating with frontier model APIs (e.g., OpenAI or similar), including prompt design, tool/function calling, streaming, and reliability/cost considerations.

  • Familiarity with advanced agent architecture concepts such as memory, guardrails/assurance, and MCP (Model Context Protocol) or similar patterns for tool interoperability.

  • Experience with conversational/agent frameworks or platforms, such as LangGraph, CrewAI, Rasa, Decagon, or equivalent orchestration frameworks, including building multi-step workflows and tool-based agents

Preferred Qualifications
  • Experience with LangGraph as a production orchestration layer.

  • Experience with vLLM or comparable model-serving infrastructure.

  • Experience in regulated-industry or financial-services technology environments, especially where enterprise scale and production-path stakes are important.

  • Experience working with business stakeholders to deliver end-to-end AI use cases, not only platform or prototype work.

  • Ability to operate in an onsite or hybrid delivery model, especially in a market such as NYC where the attachment notes a deeper finance-AI contractor pool.

  • Position the role as a senior contract role with a production-delivery bar, not as an entry-level GenAI experimentation role.

  • A 12-month engagement is reasonable for senior contractors, though onsite expectations may narrow the candidate pool.

  • If submissions are limited, relax requirements in this order: Java first, onsite days second, and do not relax the production-experience bar.

Suggested Must-Have Screening Criteria
  • Can clearly describe at least one agentic AI system they personally helped ship to production.

  • Can explain failure modes, monitoring, debugging, and operational lessons learned from a shipped system.

  • Has strong Python capability and either strong Java experience or willingness to work daily with a Java service layer.

  • Has practical experience with LangChain, LangGraph, Kubernetes, or comparable production AI infrastructure.

  • Demonstrates ability to own use cases end-to-end with business stakeholders.
