What is a GTM Engineer: The Complete Guide to Revenue Engineering

The revenue engine is no longer just sales and marketing. As B2B tech stacks become more advanced, data-driven companies are improving their go-to-market strategies. They are using systems thinking and software engineering ideas in their internal revenue operations. This GTM Engineering guide will teach you to design, automate, and scale your revenue systems for future growth.

What Is GTM Engineering?

GTM Engineering is a field. It uses software engineering. Its goal is to automate and improve a company’s go-to-market systems. Where typical software engineering builds products for external customers, GTM Engineers architect and build the internal technology powering sales, marketing, and customer success.

GTM Engineers focus on a technical approach to RevOps. They code the integrations and automated workflows that help drive revenue growth. They apply the DevOps mindset to revenue operations. They use modern engineering methods to create strong systems that grow with the business.

Key differences between GTM Engineering and other functions include:

Scope: Revenue engineering focuses on building scalable revenue systems. Software engineering, while broader, tends to build customer-facing products.
Audience: Internal revenue teams, rather than external customers or end-users.
Approach: Systems-focused, with a DevOps-style emphasis on automation and iteration.
Deliverables: Systems and infrastructure designed to scale and automate revenue operations, rather than finished software products.

Why GTM Engineering Matters

The fragmented nature of revenue tech stacks has created a critical gap in revenue functions:

Tool Complexity: The average B2B marketing tech stack has 45 tools; the average sales stack has 64 (Gartner, 2023). Each new tool or integration introduces significant maintenance overhead. These complex, disparate systems become brittle, difficult to update, and prone to failures.

Data Quality: Bad data costs companies $12.9M/year per company (Gartner, 2021). Cleaning, synchronizing, and setting up proper data hygiene is a huge technical lift for most RevOps teams to handle on their own.

Automation: 80% of high-performing sales teams use 3+ marketing automation tools (Salesforce State of Sales, 5th Edition). These sophisticated systems require considerable engineering capabilities to build.

AI and ML: As revenue teams turn to AI to power modern sales and marketing strategies, the majority lack the technical expertise to actually do it.

The benefits are clear: revenue teams with strong sales-marketing alignment generate 208% higher marketing revenue (HubSpot, 2022). GTM Engineering enables this alignment by giving revenue teams technical, scalable tools.

GTM Engineering vs. RevOps

GTM Engineering is related to, but distinct from, the RevOps function. The two terms often overlap. It is common for an organization to call someone a “GTM Engineer in RevOps” or “GTM Engineer in Growth.”

RevOps

Optimize revenue processes and improve the speed and efficiency of revenue teams.
Lead administration: Data hygiene, list maintenance, and keeping scorecards up-to-date. Planning, forecasting, and setting revenue targets.
Developing and documenting revenue processes and systems to ensure standardization and best practices across the revenue organization.

GTM Engineering

Design and build scalable revenue systems and workflows.
Coding of custom connectors and integrations to automate data flow between systems.
Building API-based integrations using GraphQL and REST.
Designing system infrastructure that can scale with business growth.
Automation of repetitive, error-prone, or high-value revenue processes.

Building and Hiring Your GTM Engineering Team

Team Structure

Embedded in RevOps: Engineers report directly to RevOps leadership and work side-by-side with RevOps Managers.

Growth Team: GTM Engineers join cross-functional growth teams alongside product managers, data scientists, and growth marketing professionals.

Hybrid Model: Engineers split their time 50/50 between Growth and RevOps teams.

Hiring GTM Engineers

Ideally, a GTM Engineer will have a few years of GTM experience in addition to the required technical capabilities. Find people who can explain how technical systems add value to the revenue process.

Example Technical Interview Prompts for GTM Engineers

Design a simple lead scoring algorithm.
Architecture for integrating data from two systems without using a 3rd party integration platform.
Design an automation workflow for moving leads through a multi-touch email nurture campaign.

Real-World Examples and Case Studies

Automating Lead Scoring and Enrichment

One B2B SaaS company automated their lead scoring system using GTM Engineers. Integrating data from their CRM, website analytics, and enrichment tools, a set of lead scoring rules were built and tested, weighting demographic data, engagement data, and traffic sources. This allowed for accurate, objective lead scores that sales reps could trust to be representative and in real-time, based on the latest prospect behavior.

Automated Identification of Expansion Opportunities

Another enterprise software vendor took automation to the next level with an intelligent expansion identification system. Integrating CRM data with product usage analytics and CS tools, GTM Engineers built a system to automatically identify high probability expansion opportunities. The pipeline was then automatically populated with relevant prospect data, flagging for sales teams.

Automated Deal Analysis and Funnel Diagnostics

A consulting firm leveraged GTM Engineering to build machine learning-based deal analytics and diagnostics. Applying ML models to identify patterns in wins and lost deals across firmographic, behavioral, and temporal data, GTM Engineers were able to build automated alerts for at-risk opportunities. Focusing their attention on the deals most likely to convert, sales teams could prioritize efforts and improve close rates.

Future Trends in GTM Engineering

AI-Driven Campaign Orchestration

Automated campaign optimization will advance by leaps and bounds, as machine learning models are applied to test, measure, and optimize campaign messages, timing, and channel mix.

Predictive Revenue Analytics

Analytics will become increasingly predictive and prescriptive, with real-time revenue forecasting and opportunity scoring built-in to guide decision-making about how to allocate limited resources.

Self-Optimizing Workflows

Revenue processes will become more autonomous, with AI systems automatically optimizing and improving upon existing workflows with minimal human intervention.

Unified Revenue Platforms

We will see the emergence of more end-to-end unified revenue operations platforms that include best-of-breed features such as automation, analytics, and AI built-in.

Build Your Own vs. Subscribing

Competitive advantage: Renting allows organizations to access state-of-the-art solutions and infrastructure that would be cost-prohibitive or require specialized expertise to build in-house.
Focus on strategy: Outsourcing technical infrastructure enables organizations to focus more resources on strategic initiatives and innovation instead of development and maintenance.
Return on investment: Renting is more predictable and budget-friendly than building, with monthly recurring expenses and easily adjustable subscription plans.
Total cost of ownership: Building and maintaining custom infrastructure and systems in-house is orders of magnitude more expensive. Factor in the cost of development and infrastructure resources, compute expenses, ongoing maintenance and updates, and a long-term time investment.

When To Build GTM

Renting is a safe default decision that works for most companies. Building is a risky, non-validated strategy that should only be considered in extreme circumstances where your unique business model has very specialized requirements.

When To Rent?

Renting is a low-risk, high-ROI strategy that accelerates your GTM growth initiatives. It allows you to access high-quality infrastructure quickly and focus on using it for competitive advantage instead of building it from scratch.

Conclusion

For smaller and up to mid sized companies, investing in GTM expertise is a significant investment and harder to justify. For larger companies with very specific workflows, the investment makes more sense.
