Full Job Description

Workable is rebuilding how the company operates using agentic frameworks, SOPs, and workflow automation. We are looking for a senior engineer to work directly with the CEO on this. The job is to turn recurring executive and company workflows into reliable tools: Claude skills, plugins, MCP servers, data integrations, internal agents, automation scripts, evals, and monitoring. This is not a role for someone who can only vibe-code demos. You should be able to ship production-grade internal software, reason about security and data access, work in a codebase, use version control properly, debug systems, and decide when an LLM should be used and when deterministic code should do the work. Key responsibilities include: * Build and maintain tooling for an enterprise Claude setup, including skills, plugins, context routing, MCP integrations, internal automations, and agent workflows. * Collaborate with the CEO and functional leaders to identify and codify recurring business workflows. * Convert unstructured operating knowledge into structured, reusable systems. * Integrate Claude securely with internal systems such as Salesforce, BI/data warehouse, Slack, Jira, Zendesk, NetSuite, documentation platforms, and internal repositories. * Rapidly prototype solutions and harden high-value automations for production use. * Implement evaluation frameworks, logging, access controls, monitoring, and documentation to ensure maintainability and reliability. * Make informed decisions on when to leverage LLMs versus deterministic software for correctness and business impact. * Help define internal standards for building and deploying AI-assisted workflows across Workable. **Requirements** ### Must-haves: * Hands-on experience building internal tools, backend services, integrations, scripts, or APIs * Hands-on experience with agentic LLM systems (such as Claude/Claude Code), including tool-calling and MCP-style integrations * Experience with at least one of Python, Ruby, TypeScript, or Nod
