Founding GTM Engineer

About the role

ABOUT SIM

Sim is building the leading platform for AI agents—enabling developers and enterprises to visually create, launch, and manage high-performing agents that automate the world’s workflows. Our mission is simple: agents will run the world, and Sim is the primary means by which that happens. We’re backed by world-class investors including Standard Capital, Paul Graham, Perplexity, SV Angel, and Y Combinator, and we’ve been open source from day one.

We're a small, fast-moving team based in San Francisco, building together in person every day. 70,000+ developers use Sim; your work ships fast and impacts real users at scale. We believe in ownership, excellence, and ambitious builders shaping the future from the ground up.

ABOUT THE ROLE

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.

You'll work full-time, in-person, out of our San Francisco office.

WHAT YOU'LL DO:

- 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

WHAT WE’RE LOOKING FOR

- 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

WHY SIM

- 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

- World-class backers: Series A led by Standard Capital, with Paul Graham, Perplexity, SV Angel, and Y Combinator

- Open source culture: 26,000+ GitHub stars and a passionate developer community

- Competitive compensation: Competitive pay + meaningful equity

- Full benefits: Comprehensive health insurance and relocation support

- Visa sponsorship available
