Senior GTM Engineer - AssemblyAI

Why AssemblyAI

AssemblyAI builds the best-in-class Voice AI models powering the next generation of voice applications. Our models serve 600M+ inference calls monthly, process 1M+ hours of audio daily, and power 2 billion+ end-user experiences. The Voice AI space is at an inflection point; we’re looking for folks truly excited to join a small team and help define the future of the industry.

We are one of the most capital-efficient AI companies on the planet - with under 100 people generating roughly $500K ARR per employee, we sit among the top 5 most revenue-dense teams within the fastest-growing AI companies today. That's not an accident; it's a deliberate choice to stay lean, move fast, and give every person on the team outsized ownership and impact.

About the Role

We're hiring our first Senior GTM Engineer to build the systems that power how AssemblyAI finds, wins, and grows customers. This is an engineering role embedded in the revenue organization: you'll own the GTM stack end-to-end — CRM, enrichment, outbound automation, routing, scoring, and the AI agents that increasingly do the work a traditional sales ops team used to do by hand.

You'll sit at the intersection of Sales, Marketing, and Data, making a small team perform like one three times its size.

What You'll Do

• Own the GTM systems stack: Salesforce, outbound and sequencing tools, enrichment providers, and the integrations between them.
• Write code every day. Scripts, internal tools, and small services are most of the job, using tools like Claude Code to build fast.
• Build AI workflows for prospecting, account research, lead scoring, and personalization that actually run in production.
• Turn product usage data (BigQuery, Looker) into signals sellers can act on: usage alerts, expansion triggers, and account health scores.
• Automate territory building and account targeting: sourcing, enrichment, dedupe, and ICP scoring.
• Keep funnel data clean and trustworthy: routing rules, field governance, and attribution.
• Prototype quickly, measure what works, and cut what doesn't; work directly with Sales and Marketing leadership on what to build next.
• Document what you build so it keeps running without you babysitting it.

What You'll Need

• 4+ years in GTM/sales engineering, growth engineering, RevOps with heavy build responsibility, or software engineering with GTM exposure.
• Strong SQL and Python; comfortable owning production automations (APIs, webhooks, scheduled jobs, error handling).
• Solid software engineering fundamentals: you write clean, maintainable code, think in systems, and are at home with version control, code review, and debugging.
• Fluency with AI-assisted development tools like Claude Code as a core part of how you work.
• Hands-on Salesforce depth: objects, flows, routing, and API-level integration work.
• Real experience putting LLMs into workflows — prompt design, evaluation, and knowing when AI is the wrong tool.
• Experience with the modern GTM stack (enrichment platforms like Clay or similar, sequencers, warehouse-native tooling).
• A builder's mindset with an operator's judgment: you scope for business impact, ship iteratively, and measure results in pipeline and revenue.
• Low ego, high ownership, and comfort being the single-threaded owner of an entire domain.
