GTM Engineer San Francisco · On-site · Full-time Base salary: $100,000–$200,000 USD annually. Equity: 0.2–0.5%. Visa sponsorship is available. Occasional travel may be required. Build the system that brings us customers This is a builder-first role working directly with the founders. As our first GTM engineering hire, you will build Sainapse’s customer-acquisition system with agents, data, code, and experiments. Qualified enterprise demos are the north-star metric. Your work should create useful customer conversations and pipeline, and turn proven internal workflows into product. What you will build An empirical ideal-customer-profile system: discover accounts, enrich data, score fit, segment, and prioritize using downstream outcomes. Research, personalized messaging, sequences, qualification, and booking workflows with reliable attribution and data quality. Experiments across outbound, search, content, paid channels, events, partnerships, and useful tools. Define hypotheses and measurement, then stop, improve, or scale based on evidence. A commercial website that converts: work with the founders, design, and marketing on positioning, pages, copy, proof, and calls to action. Internal Sainapse workflows for research, scoring, qualification, and prospect preparation. Productize what proves useful while keeping pipeline outcomes first. Self-serve experiences such as interactive demos, guided qualification, use-case discovery, and paths into a proof of concept. You will join customer and prospect calls and create account briefs, follow-up, and ROI materials. The founders will own major sales calls, closing, and commercial negotiations. What success looks like In the first month, learn the product and customer history, establish an ICP and measurement baseline, and launch focused experiments. Initial goals are 2–4 qualified demos per week by day 60 and 5–7 by day 90, calibrated with the founders against the baseline and available budget. A qualified demo means a relevant company and stakeholder, a plausible problem, evidence of fit or timing, and a conversation worth founder attention. Calendar bookings alone are not success. Optimize for conversation quality and progression. What you bring Evidence that your work created pipeline or revenue: show the baseline, timeframe, result, and your personal contribution. The ability to build, inspect, and improve systems using agents, APIs, scripts, tools, and data. Experimental and analytical judgment, including knowing when to abandon a hypothesis. Comfort with customer conversations, technical learning, hands-on execution, and clear communication. Ownership from idea through measured outcome. Around 3–6 years of relevant experience is a guide; demonstrated output matters more than credentials. About Sainapse Sainapse builds agent-first software for customer operations, helping teams resolve work across the systems they already use. Our production work spans customer support and document and order workflows, with configurable autonomy and human review. We are also building account intelligence that connects customer signals. We are a small team with broad ownership. We value first-principles thinking, direct communication, thoughtful use of AI, and evidence of customer impact. You will work closely with the founders and our product, engineering, and delivery teams.
