Senior GTM Engineer

Role Overview

• Own the design, build, and maintenance of Clay tables, waterfall enrichment flows, and AI column logic that power Perk's outbound engine.
• Engineer multi-step Clay workflows using webhooks, HTTP API integrations, and conditional branching to automate account and contact sourcing at scale.
• Build and iterate on AI prompt layers within Clay using LLM columns to generate personalised outreach snippets, research account context, and qualify leads programmatically.
• Construct and maintain signal-based prospecting systems that ingest buying triggers (hiring signals, funding events, intent data) and route them into prioritised Clay tables for Sales activation.
• Integrate Clay with Salesforce, Outreach, and data providers (Clearbit, Apollo, LinkedIn, PredictLeads, and others) to maintain clean, enriched, and timely GTM data.
• Evaluate and implement AI tooling, including LLM-based research agents, AI SDRs, and prompt-engineered enrichment flows, to scale outbound relevance without scaling headcount.
• Design and maintain Outreach sequences that incorporate AI-generated personalisation, ensuring high-volume dialling and email campaigns feel 1:1 at scale.
• Identify and automate repetitive GTM operations (list building, data hygiene, routing, deduplication) using Clay, Make, and custom API scripts.
• Maintain a working knowledge of the AI GTM vendor landscape and bring forward well-reasoned recommendations on new tooling.
• Own TAM sourcing and enrichment workflows, building waterfall logic that sequences providers (e.g. Clearbit -> Fullenrich -> LinkedIn) to maximise contact coverage and data completeness.
• Maintain accurate account and contact data across Salesforce and connected GTM tools, with automated hygiene rules to catch decay before it reaches Sales.
• Define and enforce data quality standards for ICP segmentation, territory assignment, and pipeline attribution.
• Configure and maintain the core GTM stack (Salesforce, Outreach, Gong, Clay) to support high-volume outbound activity and ambitious pipeline targets.
• Partner directly with Sales to diagnose productivity bottlenecks and build systems solutions, from routing logic to sequence architecture to dialler integrations.
• Rapidly troubleshoot system and workflow failures to minimise lost selling time during core business hours.
• Serve as the primary systems contact for Revenue Systems and GTM Engineering support, owning issue resolution end-to-end.
• Execute against the Revenue Systems roadmap in partnership with the Senior Manager and central GTM Engineering team.
• Share learnings, workflow templates, and Clay builds with the global GTM Engineering team to drive consistency and compound improvement across regions.
• Provide ground-level feedback to inform roadmap prioritisation, surfacing patterns in what's breaking, slowing, or blocking revenue teams.

Requirements

• 6+ years in GTM Engineering, Revenue Operations, or Sales Operations in a B2B SaaS environment, with a strong technical orientation.
• Hands-on Clay expertise; you have built complex Clay tables, waterfall enrichment flows, webhook integrations, and AI column prompts in a production environment, not just experimented with the tool.
• Direct experience applying AI to GTM workflows: prompt engineering for LLM-based enrichment, AI-powered personalisation at scale, or building/evaluating AI SDR tooling.
• Salesforce proficiency: building and maintaining custom objects, flows, reports, and data integrity logic.
• Familiarity with sales engagement platforms (Outreach or SalesLoft) and their integration with CRM and enrichment tooling.
• Ability to work with APIs, webhooks, and lightweight automation tools (Make, Zapier, or equivalent) without requiring engineering support for every integration.
• Strong data instincts: you build systems that keep data clean, catch decay early, and ensure Sales always operates from a high-quality foundation.
• Experience building signal-based outbound systems using intent data, hiring signals, or funding triggers surfaced through Clay or similar infrastructure.
• Familiarity with data providers in the GTM stack: Clearbit, Apollo, PredictLeads, LinkedIn Sales Navigator, Bombora, or similar.
• Exposure to Gong data and using conversation intelligence to inform outbound strategy or sequence design.
• Experience in a high-growth SaaS environment.
