Lead Engineer - Workflow Builder DSL

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…
