Job description

About SourceCo

SourceCo is a technology-enabled buy-side investment bank specializing in proprietary deal sourcing for private equity firms, family offices, and corporate acquirers. We leverage proprietary software, data enrichment, and automation to identify niche acquisition targets that align with our clients' investment theses.

What are we looking for:

SourceCo finds companies for PE firms, family offices and corporate acquirers before they're for sale. We map 2M+ companies every week and our team has 1,000+ conversations with founders every month.A client might ask for a phase two clinical trials operator with at least nine trial managers. No database can find that. The GTM engineer builds what does: the data, enrichment, sending and calling systems behind every search we run.You'll work side by side with our CEO, who built the scrapers and ran the outreach behind three platform acquisitions before SourceCo. Our clients are PE firms, so accuracy comes first: a small miss at step one becomes a big one by step five.You don't need to know our tools, and we teach the M&A. What we can't have is someone who needs to be told what to build.

Responsibilities:

Shared systems (about 70% of the role)

• Build and run the pipeline that finds companies matching a client's criteria, enriches them and finds the right owner's contact details.
• Run our email sources in price order and verify every hit before anything is sent.
• Automate inbox setup: type in a domain, and the sending domains, inboxes and warm-up set themselves up.
• Join email, calls, LinkedIn and direct mail into one record per owner, so a reply on one channel stops the others.
• Build campaign reporting that pulls straight from our tools, so nobody updates a spreadsheet by hand.

Client problems (about 30%)

• Join client calls when a search isn't producing meetings, find the cause, and fix it in the system so it stays fixed.
• Turn each one-off fix into something every client benefits from.

The stack

• Clay (enrichment), Smartlead (sending), HeyReach (LinkedIn), PhoneBurner (calls), n8n (automation), Claude Code (building), plus our own data warehouse and platform. Any of it can be swapped when something better comes along.

Requirements:

• You've built systems other people rely on: outbound, data pipelines, enrichment or automation, with results you can show.
• Comfortable with APIs, webhooks, SQL and scripting. Clay and n8n experience helps, and you'll learn the rest fast.
• You care about accuracy. You check the data before it goes out.
• You can explain a problem clearly on a client call and to the team.
• You see a problem and fix it without waiting to be asked.

Nice to have

• Experience with Smartlead, HeyReach, PhoneBurner or similar tools.
• Building with Claude Code or other AI coding tools.
• Outbound for a B2B services business or a finance audience.

Compensation

$115,000 to $145,000 base for US hires, plus a bonus tied to the deals we close. Outside the US: $60,000 to $95,000 USD base, with the same bonus. Fully remote.

Why Join SourceCo?

• Work side by side with our CEO, who built the scrapers and outreach behind three platform acquisitions before SourceCo.
• The hardest target in GTM: private-company owners no database can find.
• Your systems run behind 2M+ companies mapped every week.
• A bonus tied to the deals we close.
• Fully remote, and we teach the M&A.
