Founding GTM Engineer

This is a foundational role: Sim is hiring our first GTM Engineer to build the company’s go-to-market and RevOps infrastructure from the ground up. You won’t just optimize existing workflows-you’ll architect them. You’ll partner directly with leadership to define, implement, and scale our GTM systems, automations, and data flows. If you want to operate as a technical founder for our GTM function and ship quickly with massive ownership, this role is for you., * Build from zero: Create Sim’s GTM infrastructure from scratch-integrating best-in-class tools like Salesforce, Clay, Gong, enrichment APIs, and more into a seamless automated engine

• Invent internal automation: Design and build AI agents and custom workflows to automate account research, minimize manual tasks, and personalize outreach at scale
• Engineer data flows: Architect the middleware and webhooks that ensure data integrity and sync between Sim’s product, CRM, and internal systems
• Programmatic GTM: Translate top-level GTM strategy into automated workflows, custom internal tools, and data-driven outbound campaigns
• Found and scale: Set the technical standard and shape the DNA of Sim’s GTM/Revenue Operations function for years to come

• 3+ years of experience in GTM Engineering, technical RevOps, or similar technical roles
• Proficiency writing code (Python, JavaScript, or SQL) and familiarity working with APIs
• Track record of integrating, automating, and scaling SaaS and AI tool stacks
• Strong understanding of sales funnels, GTM business logic, and operations
• Experience with modern GTM tools (Clay, Claude Code, Parallel, Unify, Sim, scraping/indexing the web, etc.)
• High bias toward action and “shipping v1 today”-you thrive in ambiguity and fast-paced teams
• Deep ownership mentality; you want end-to-end responsibility for Sim’s GTM architecture and future team

• Foundational impact: You’ll build and define Sim’s GTM infrastructure and shape how agents are sold, deployed, and supported
• Immediate scale: Your work ships to 70,000+ developers and customers right now

• Open source culture: 26,000+ GitHub stars and a passionate developer community
• Competitive compensation: Competitive pay + meaningful equity
