About this role

Founding Full-Stack Engineer

About Arusto:

Arusto is transforming Learning & Development by automating the creation of tailored learning materials from unstructured content repositories. We work with organizations including a leading private university and a global corporate learning publisher, and we are building what we believe is the first autonomous knowledge-asset creation engine for L&D.

The Role:

We’re hiring a Full-Stack Engineer to join our small, high-ownership, fully remote team. You’ll work across product, infrastructure, and AI-powered workflows to help build and scale a category-defining SaaS platform.

This role is for someone who likes moving fast, taking responsibility, and building real product in a startup environment. You should be comfortable owning features end-to-end, from frontend implementation to backend systems and production deployment.

What You’ll Work On:

  • Build and ship product features across the frontend and backend
  • Develop scalable workflows for content generation, transformation, and delivery
  • Integrate AI capabilities into core product experiences, including LLM-powered workflows and agent-like systems
  • Design and maintain APIs, services, and data pipelines
  • Improve system reliability, performance, and developer velocity
  • Work closely with the founding team on product direction and technical decisions

Core Stack:

  • Frontend: React, Next.js, TailwindCSS, shadcn/ui
  • Backend: Python, Node.js
  • Infrastructure: AWS, GCP
  • Databases: PostgreSQL, Pinecone
  • AI / LLM Tools: Agentic Framworks with Claude/OpenAI

What We’re Looking For

  • Strong experience as a full-stack engineer building and shipping production software
  • Strong frontend skills with React and Next.js
  • Strong backend skills in Python and/or Node.js
  • Experience designing scalable systems and owning features end-to-end
  • Comfortable working independently in a startup environment with limited structure
  • Strong product instinct and bias toward execution
  • Clear communicator who can work well in a small remote team

Nice to Have:

  • Experience integrating LLMs into production products
  • Experience building AI workflows, agents, or tool-using systems
  • Experience with retrieval systems, embeddings, vector databases, or RAG pipelines
  • Experience evaluating model quality, latency, and cost tradeoffs in production
  • Familiarity with prompt engineering, orchestration frameworks, and agent reliability issues
  • Experience deploying and maintaining AI-backed systems on AWS

Important Notes

  • This is a high-commitment role. We are looking for someone focused on building with us long-term.
  • Agency applicants are not a fit for this role.
  • Background check required.

What We Offer

  • Competitive compensation
  • Equity after probation
  • A chance to join a small founding engineering team
  • Meaningful ownership and direct impact on product and company direction
  • The opportunity to help define the future of AI-driven learning
