[Hiring] Senior Full Stack Developer @Lean Layer

5d ago - Lean Layer is hiring a remote Senior Full Stack Developer. 💸 Salary: usd 40,000 - 80,000 per year 📍Location: USA, Brazil

Role Description

Lean Layer is the #1 Rated RevOps Agency on G2, and we’re doubling our consulting and engineering capabilities over the next year. Our reputation is built on excellent results, which means we need to keep hiring exceptional builders. We’re looking for a Senior Full Stack Developer to own and evolve the AI infrastructure that powers both our internal operations and customer-facing deployments.

This role focuses on building and maintaining full-stack systems that integrate data pipelines, LLM orchestration, and enterprise-grade application layers. You will be responsible for developing both the user-facing interfaces and the backend systems that power scalable, reliable, and intelligent applications.

Working closely with RevOps Consultants, Data Engineers, and AI-focused teams, this role ensures that complex AI-driven workflows are translated into robust, usable, and production-ready systems.

The ideal candidate combines strong full-stack engineering skills with systems thinking, enabling them to design scalable architectures, handle real-world data complexity, and build products that balance automation with human-in-the-loop workflows.

Qualifications

  • Enjoys owning systems end-to-end, from UI to infrastructure
  • Thinks in terms of systems, state, and data models—not just features
  • Is comfortable working with real-world complexity, edge cases, and evolving requirements
  • Has a strong bias toward building reliable, maintainable, and scalable systems
  • Understands how to integrate AI into real products, not just prototypes
  • Thrives in small, high-ownership environments
  • Can balance speed of execution with long-term system design

Requirements

  • Strong experience with Python and React/TypeScript
  • Experience designing REST APIs and working with relational databases (PostgreSQL)
  • Familiarity with authentication systems and role-based access control
  • Experience with Docker, GCP (Compute Engine), and CI/CD pipelines
  • Experience building production systems with real data models and workflows
  • Experience working with LLM APIs and handling streaming responses
  • Background in small teams or startups with full-stack ownership

Preferred Experience

  • Experience with vector databases such as ChromaDB or Pinecone
  • Experience building Slack apps (Bolt SDK or similar)
  • Experience developing workflow systems or multi-tenant architectures
  • Experience deploying infrastructure across multiple customer cloud environments
  • Portfolio or examples of past full-stack or systems-level projects
