GTM Engineer (Growth Engineer) - Freelancer

We are looking for a GTM Engineer (Growth Engineer) to design and build the technical systems that power scalable acquisition and revenue growth.

Your role is to turn marketing, sales, and data infrastructure into automated growth engines.

Instead of manually running campaigns or processes, you build the systems, automations, and integrations that make growth repeatable, scalable, and measurable.

You will operate at the intersection of growth strategy, engineering, and data, helping teams move faster by removing operational friction and building robust GTM infrastructure.

You combine technical execution with growth thinking and understand that the most effective GTM strategies are powered by automation, experimentation, and data-driven systems.

You also understand how to structure and activate a Total Addressable Market (TAM), build scoring models, and enable outbound systems that drive targeted acquisition.

You will work in an international environment and must be able to operate professionally in both English and French.

Your mission

• Design and build GTM infrastructure that enables scalable acquisition and pipeline generation

• Structure and operationalize TAMs (Total Addressable Markets) to support targeted growth strategies

• Turn manual marketing and sales workflows into automated systems

• Build and maintain data and automation pipelines connecting marketing, sales, and product tools

• Develop systems for lead enrichment, routing, scoring, and segmentation

• Build and optimize lead scoring models to prioritize high-value accounts and opportunities

• Enable and automate outbound acquisition systems (targeting, enrichment, sequencing)

• Enable faster experimentation by building growth experimentation infrastructure

• Improve the efficiency of GTM teams by eliminating operational bottlenecks

• Create frameworks that allow Growth and Sales teams to test, launch, and scale campaigns faster

• Ensure data flows cleanly across tools, enabling reliable analytics and attribution

What you will work on

• Designing and maintaining GTM systems and growth infrastructure

• Automation workflows across CRM, marketing, and sales tools

• TAM definition, segmentation, and activation workflows

• Lead enrichment pipelines and data workflows

• Lead scoring systems and prioritization frameworks

• Outbound infrastructure (data sourcing, enrichment, sequencing, personalization)

• Experimentation infrastructure for growth initiatives

• Integrations between marketing, sales, and product tools

• Attribution systems and funnel analytics

• Internal tools that accelerate campaign launches and testing

• Building repeatable growth frameworks instead of one-off campaigns

Performance mindset

• Build systems that generate qualified pipeline and measurable business impact

• Replace manual work with automation and scalable infrastructure

• Enable teams to launch and test initiatives faster

• Turn successful experiments into repeatable systems

• Optimize processes for speed, reliability, and scalability

• Design infrastructure that supports continuous GTM experimentation and iteration

• Strong understanding of marketing, sales, and data systems

• Experience building automations, integrations, and scalable workflows

• Experience working with TAM definition, segmentation, and targeting strategies

• Experience building or managing lead scoring and prioritization systems

• Strong understanding of outbound systems and workflows (enrichment, sequencing, targeting)

• Comfortable working with APIs, automation tools, and data pipelines

• Systems-thinking mindset with strong problem-solving skills

• Experience supporting growth experiments and acquisition initiatives

• Comfortable working on client missions and collaborating with cross-functional teams

• Strong collaboration with Growth, Marketing, Sales, and Data teams

• Impact-driven and execution-focused
