We’re hiring an AI Developer with a strong React and Node.js background to build AI driven features and automation for an intelligent staffing platform. You’ll work across LLMs, backend services, and modern front end interfaces to turn messy real world workflows into fast, reliable, production systems.

This role is ideal for engineers who can move between frontend, backend, and AI layers—and enjoy shipping features that make a measurable operational impact.

• Build AI powered features using OpenAI, Anthropic, or similar LLMs
• Design and develop backend services and APIs using Node.js and Express.js
• Create and ship React.js interfaces that surface AI insights and workflows
• Build end to end AI systems including embeddings, RAG pipelines, and automation flows
• Apply prompt engineering, evaluation, and tuning to improve model behavior
• Integrate AI workflows with tools like n8n or Zapier
• Work closely with product and engineering teams to deliver customer facing AI features
• Monitor usage patterns and iterate quickly based on real world feedback
• Communicate clearly with strong written updates in a remote async environment

What We’re Looking For

• 5+ years of experience building production applications with React.js and Node.js
• 2+ years of hands on experience building with LLMs or ML driven systems
• Strong proficiency in Python or Node.js for AI integration workflows
• Experience with REST APIs, backend architecture, and production deployment
• Familiarity with vector databases, embeddings, and retrieval pipelines
• Strong product intuition and ability to turn unclear problems into scoped solutions
• Comfort working in a fast moving, remote environment with written communication as the norm
• English proficiency

Nice-to-Haves

• Experience with fine-tuning or custom model training.
• Background in marketplaces, automation tools, or workflow-heavy products.

How You Would Fit

• Customer first: We build AI around real operational problems
• Written and open: Most collaboration happens in writing
• High ownership: Engineers own systems end to end

What We Offer

• Competitive salary and benefits package. - Opportunity to work on impactful AI projects that improve healthcare staffing and patient care. - Collaborative and inclusive team culture with a focus on professional growth. - Access to cutting-edge tools and cloud technologies. - Flexible work environment with a commitment to work-life balance.
