AI Engineer/Staff Software Engineer – Agentic Development

Job Title: AI Engineer/Staff Software Engineer – Agentic Development

Location: Hoboken, NJ (first preference is local/ remote ok but travel required when needed)

Duration: 6 Months

Job Summary:

We are seeking a highly skilled AI Engineer who can define and scale how our engineering organization builds simulation software with AI agents. This role requires deep fluency in "loop engineering" with tools like Claude Code: designing the feedback loops, guardrails, and workflows that let AI agents safely and effectively contribute to production codebases. You'll need to understand the full agentic software development lifecycle, from context design through evaluation, deployment, and observability, while also being a hands-on expert across our core stack.

This is a staff-level role: you'll collaborate with other engineers to set technical direction, define best practices for agentic development across teams, and remain deeply hands-on in architecture and code.

Key Responsibilities:

AI & Generative AI Development

• Design and implement "loop engineering" workflows using Claude Code and similar tools, defining how agents plan, execute, test, and iterate on code changes

• Architect Model Context Protocol (MCP) servers and tool schemas that are legible and safe for LLM agents to use

• Define human-in-the-loop checkpoints, autonomy boundaries, and rollback strategies for agent-driven changes

• Build evaluation harnesses and observability practices to measure agent output quality and catch regressions

• Design and review microservice and micro frontend architecture using C4 diagrams and Domain-Driven Design principles

• Drive test-driven development practices across teams, including contract testing between services

• Own technical decisions across our Java microservices, Node.js services, React/micro frontend UI, and Python tooling

Learning Content & Assessment Development

• Design and develop hands-on lab activities, practical exercises, guided projects, and simulations.

• Create technical learning content for AI, cloud, software engineering, and emerging technologies.

• Develop assessment questions including:

o Multiple Choice Questions (MCQs)

o Scenario-based questions

o Coding exercises

o Capstone projects

o Knowledge checks

• Utilize Claude and other AI tools to generate, review, and improve educational content.

• Align content with learning objectives, competency frameworks, and certification standards.

Full Stack Development

• Develop responsive web applications using React.js.

• Build backend services and APIs using Node.js and Express.js.

• Integrate AI services and LLM APIs into web applications.

• Design and implement secure RESTful APIs and microservices.

• Develop dashboards for content management, assessment reporting, and learner analytics.
