GTM Engineer

Field sales powers the economy — but most teams are struggling. Reps are buried in admin work, managers are stretched thin, and leaders can’t see what’s really happening in the field. Siro is redefining how field sales teams learn, perform, and win. We started as an AI-powered coaching platform that helped reps improve their outcomes in the field. Today, we’re something much bigger — an intelligent companion that automates sales reps’ tedious admin work, gives managers real-time visibility, and helps executives see around corners. Our platform integrates with systems like Salesforce, analyzing thousands of in-person sales conversations to surface insights, automate workflows, and drive better outcomes across the org. Think Iron Man’s Jarvis for sales — proactive, personalized, and built directly into the tools teams already use. Siro has raised $75M and is backed by world-class investors like Index, Fika, CRV, and SignalFire. We are trusted by leading home-improvement, retail, hospitality, and automotive brands, and powered by a lean team from Meta, McKinsey, Doordash, and Uber. We’re building the future of human-AI collaboration in sales — and we’re just getting started. As Siro's first dedicated GTM Engineer, you'll build the data flows that power how we find and win new customers. From sourcing third party data to managing connections between our CRM, product data, and outbound tools, your role will be critical to helping our company scale. This is a builder role. You'll help shape the systems for our GTM organization’s outbound motion, and over time you’ll analyze the data we generate to determine works best for Siro. The top priority on day one, however, will be executing on roadmap that we’re confident will drive a step change in our SDR team’s effectiveness. Key Responsibilities:

• Build and automate GTM data flows end to end.Turn scoped requirements into triggers and pipelines that source, enrich, and sync data across tools we leverage so that our team can move even faster. You’ll capture the digital signals that enable sellers to focus their efforts on the right accounts.
• Own the GTM data layer.Ensure the data that enters our source of truth systems (CRM, data warehouse) is clean, deduplicated, and trustworthy. Maintain field definitions, integrations, and sync logic.
• Document and maintain what you build.Make sure the systems we create don’t break silently and are easy to understand — so that as our team grows, others can learn to use them quickly.
• Work closely with GTM leaders.Pressure-test scopes, flag material edge cases, estimate effort, and push back when there's a simpler path.
• Refine analysis and reporting.Write the queries and models behind pipeline, funnel, and account-level reporting, so leaders make decisions on real numbers.
• Develop a point of view.Analyze the systems as they operate so that you can make data-driven recommendations for what Siro should build next.
• Evaluate investments.Help determine via technical evaluation when Siro should (and should not) be spending on new platforms or datasets for our team of sellers.

Requirements:

• 3–5 years of hands-on experience in data science, data or analytics engineering, and/or GTM engineering
• Strong Python and SQL skills
• Experience building and maintaining data pipelines, API integrations, and/or ETL workflows
• Comfort working with CRM data (HubSpot or Salesforce) and its messiness
• Experience with GTM tools such as Clay,Freckle.io, and/or Deepline
• A track record of taking a spec from someone else and shipping it reliably, on time, and with strong judgment on edge cases that require accounting for
• An AI-forward mindset, ideally from using LLMs or AI agents inside workflows
• Clear written communications. You can explain a technical tradeoff to a sales leader in a few sentences.
• Curiosity about how sales teams work and what makes them win

Nice to have

• Experience at an early-stage B2B SaaS company
• A technical degree (CS, statistics, math, engineering) or equivalent experience
• Familiarity with outbound platforms such as Nooks, Outreach, and/or Trelllus
