Job description

Role Summary

We’re hiring a Lead Engineer, Workflow Builder DSL to define and enforce the data‑layer grammar that powers every automation inside HighLevel. Your mission: ensure workflows are valid by construction and programmatically safe to create, through strict contracts, semantic validation, static analysis, and high‑coverage tests. You’ll own the canonical Workflow DSL that represents how workflows are structured, stored, and validated. Your work guarantees that every workflow, whether created in the UI, cloned via snapshot, or generated programmatically, is predictable, version‑safe, and never corrupt.

Responsibilities

• Define the DSL: Design and maintain the canonical syntax and semantics for workflows
• Schema authority: Own JSON Schemas and TypeScript types for validation, linting, and generation
• Programmatic CRUD: Design contracts for safe workflow creation via public and internal APIs
• Validation layer: Implement semantic validators (current POC in Zod; open to alternatives)
• Linting & codemods: Ship tools that enforce structure guardrails and auto‑repair common errors
• Testing discipline: Establish unit, integration, and golden tests for workflow creation paths
• Static analysis: Add graph checks for loops, dangling nodes, and invalid edges
• Cross‑team contracts: Define interfaces with Engine and Snapshot for schema exchange and validation
• Operational ownership: Monitor DSL validation services; ensure 99.9 % availability and low error rate

Requirements

• 7+ years building and owning complex backend systems.
• Deep experience with typed DSLs, ASTs, or schema‑driven architectures
• Fluent in TypeScript and validation frameworks (Zod, Ajv, or JSON Schema)
• Proven history designing public or versioned APIs
• Strong testing discipline and data‑integrity mindset
• Comfortable owning production services and reliability metrics
• Nice to have: compiler/graph background, schema evolution work, or tooling for developer productivity
