GTM Lead

Job Description

About the Role

A YC-backed, seed-stage AI developer infrastructure startup in San Francisco is looking for a GTM Lead to own the entire go-to-market function from day one. The company builds sandboxing and testing infrastructure for AI agents — a nascent, fast-moving space that has already hit product-market fit ahead of schedule, with demand outpacing supply.

You'll be the first dedicated GTM hire at a tight-knit four-person team, working directly with the founders to build marketing, tune the sales pipeline, and run the GTM operations that prove what's working. This is a hands-on execution role — you do the work yourself before you build a team. Visa sponsorship is not available for this position.

• Own marketing end-to-end: positioning, messaging, content, launches, and demand generation.

• Co-own story and brand direction with the founding team, then execute the strategy and iterate based on results.

• Tune the sales pipeline by analyzing how leads arrive, get qualified, and where they stall — then fix the bottlenecks.

• Run constant experiments and let data, not opinions, drive what you double down on.

• Reach a technical audience authentically — engineers and platform teams who reject marketing speak.

• Handle GTM ops: tooling, tracking, and reporting that surface what's actually working.

• Write copy, build sequences, and read the numbers yourself until the motion is proven.

• Hire and lead marketers once you've validated the playbook.

Must-haves:

• 3+ years of hands-on B2B growth marketing experience, with direct involvement in taking a company from Series A through Series B — in the room making decisions, not adjacent to them.

• Deep technical fluency: you can explain complex infrastructure or developer tooling concepts to engineers without a translator.

• Proven ability to build and execute an end-to-end B2B marketing function (positioning, messaging, content, demand gen, pipeline tuning) independently.

• Demonstrated track record of running A/B tests and experiments at volume, with data-driven decision-making to match.

• Experience marketing to technical audiences — engineers, platform teams, infrastructure buyers — without falling back on marketing clichés.

• Hands-on GTM ops experience: pipeline tracking, analytics, reporting infrastructure.

• Experience optimizing sales pipelines including lead qualification, bottleneck identification, and conversion improvement.

Strong pluses:

• Background in developer tools, infrastructure, or platform companies.

• Published technical writing under your own name — newsletter, Substack, blog, or documentation with a real audience.

• Experience leading a company through a repositioning or rebrand and measuring its impact on metrics.

• Prior experience hiring and managing marketing team members.

• Base salary: $180,000+ USD annually (commensurate with experience)

• Early-stage equity in a well-funded, high-traction company (Seed stage, backed by top-tier investors)

This role is on-site in San Francisco, CA . Candidates must be based in San Francisco or willing to relocate. Remote or hybrid arrangements are not available for this position.
