The Position

We’re looking to hire a Full-Stack AI Engineer (Agentic Systems) to join our team. This is a high-impact, client-facing role designed for a "plus-plus" version of a developer, someone who doesn't just build, but defines the architecture of how global enterprises adopt agentic workflows. You will serve as a strategic consultant and technical lead, helping regulated industries and Fortune 500 clients transition from traditional development to AI-augmented engineering productivity.

• Strong history of developing AI-powered web applications using React, Next.js, JavaScript, and TypeScript.


• Extensive experience building backend services and APIs with Node.js or Python.


• Track record of productizing early-stage Generative AI prototypes into scalable, production-ready MVPs.


• Solid understanding of cloud-based architectures on AWS and containerization tools such as Docker.


• Well-versed in database management systems, including PostgreSQL and MongoDB.


• Familiar with RAG (Retrieval-Augmented Generation) pipelines, vector databases, or orchestration frameworks.


• Capable of working with GraphQL, microservices, or event-driven systems in fast-paced environments.


• Ability to work through new and difficult issues and contribute to libraries as needed.


• Ability to create and maintain continuous integration and delivery of applications.


• Forensic attention to detail.

• Ability to consistently work 40 hours per week.

What We Offer

• Competitive Salary.


• Paid Time Off (vacation, sick leave, parental leave, and holidays).


• 100% remote work.


• The ability to work with leading startups and Fortune 500 companies.


• Health, dental, and vision insurance.
