Job description

Looking for a experienced GTM Engineer to join the fastest growing outbound agency.

About SalesSourcers

SalesSourcers is a B2B outbound sales agency helping companies generate qualified sales opportunities through cold calling and cold email.

We believe one of the biggest factors in outbound performance happens before an SDR ever picks up the phone or an email is sent: **who we target.**

A great SDR calling the wrong prospects will still produce mediocre results. The best cold email copy sent to the wrong accounts won't perform either.

We're already strong at building targeted lead lists and outbound campaigns for our clients. We're now hiring another experienced **GTM Engineer** to take this to the next level.

The Role

This is not a traditional list-building or data research role.

You'll be responsible for the strategy, data and systems behind our outbound campaigns, ensuring our SDRs and cold email campaigns consistently reach the right companies and people at the right time.

You'll work across multiple B2B clients, each with different markets, ICPs and buying triggers. Your job is to figure out who we should target, why we should target them, when we should reach them and how we can use data and technology to do it at scale.

You’ll have a direct impact on lead quality, SDR performance, meetings booked and pipeline generated for our clients.

Key Responsibilities

ICP & Targeting

• Build highly targeted, high-quality lead lists for cold calling and cold email campaigns
• Translate client offerings into clear and actionable ICPs
• Go beyond basic firmographics and job titles to identify companies with genuine reasons to buy
• Identify buying signals, intent, triggers and market opportunities
• Develop targeting strategies across different industries, markets and personas
• Continuously analyse campaign results and use the data to improve targeting
• Build and improve systems for sourcing, enriching, validating and segmenting prospect data
• Use APIs, AI and automation to improve the speed and quality of our GTM workflows
• Use tools such as Claude Code to automate research and build scalable data processes
• Integrate different data providers and GTM tools into repeatable workflows
• Find new ways to identify prospects that traditional databases and basic filters miss
• Maintain high standards around data accuracy, enrichment and campaign readiness

Cold Email

• Build and manage cold email campaigns from strategy through to execution
• Maintain strong email deliverability across campaigns and infrastructure
• Develop campaign segments and messaging based on ICP, persona and buying signals
• Monitor campaign performance and identify opportunities for improvement
• Continuously test targeting, messaging, offers and campaign structures
• Use campaign data to improve future campaigns and lead-generation strategy

Campaign Performance

• Work closely with our SDR and Account Management teams to understand what is happening on calls
• Analyse which industries, companies, personas and signals are generating the strongest results
• Use call and email performance data to continuously refine campaigns
• Identify underperforming campaigns early and develop new targeting strategies
• Help turn what we learn across hundreds of outbound conversations into better GTM decisions

What We're Looking For

We're looking for someone who is commercially minded, highly technical and obsessed with finding better ways to identify and reach the right prospects.

You should have:

• Extensive experience working as a GTM Engineer or in a highly similar role
• A proven track record building and operating successful B2B outbound campaigns
• Strong experience across both cold calling and cold email GTM strategies
• Advanced experience sourcing, enriching and manipulating B2B prospect data
• Strong understanding of ICP development, segmentation, intent data and buying signals
• Experience building automated GTM workflows and data pipelines
• Strong knowledge of cold email infrastructure and deliverability
• Experience working with APIs, automation tools and AI
• Experience using AI coding tools such as Claude Code
• Strong analytical skills and the ability to turn campaign data into actionable decisions
• The ability to work across multiple clients, industries and campaigns simultaneously
• 2+ years of GTM Engineering Experience
• Experience ats similar agency or SaaS company

What Success Looks Like

Success in this role isn't measured by how many leads you can scrape.

It's measured by whether the data and systems you build help us generate better commercial outcomes.

That means:

• Higher-quality prospect data
• Better SDR conversations
• Higher cold-call conversion rates
• Better cold email performance
• More qualified meetings
• More pipeline generated for our clients
• Less SDR time wasted calling poor-fit prospects
• Faster identification of new markets and opportunities
• Repeatable GTM systems that allow us to scale

Who This Role Is For

This role is suited to someone who enjoys solving difficult GTM problems.

You don't just ask, "How do I find 5,000 companies that match these filters?"

You ask, "What makes a company likely to need this service right now, and how can we identify that at scale?"

If you have extensive GTM Engineering experience, understand outbound deeply and enjoy combining commercial thinking with data, AI and automation, we'd love to hear from you.
