# B2B marketing systems builder

A remote contract role at a B2B company I work with. I share who the company is once we're talking.

## What the B2B marketing systems builder does

Build the AI workflows that run paid media, tracking and reporting for B2B companies, then run them: weekly reviews that propose changes for approval, lead-to-deal checks and client reports.

- Build scheduled AI workflows that pull Google Ads, LinkedIn Ads and HubSpot data and flag what needs attention
- Turn written playbooks into workflows, with a person approving any change to ad spend
- Check conversion tracking against the CRM, from first lead to closed deal
- Make and check approved ad changes in Google and LinkedIn
- Build the monthly report each company gets
- Write down how each workflow works so someone else can run it

## What the B2B marketing systems builder role needs

- You've run Google Ads or LinkedIn Ads for B2B companies and judged them on pipeline, not form fills
- You've set up and checked conversion tracking against a CRM like HubSpot or Salesforce, where leads turn into deals weeks later
- You've built automations that call APIs, using Claude, MCP servers, n8n, Make or your own code
- A plus: you've marketed to technical or regulated buyers, like security, fintech or data
- You've done this work for B2B companies, where a sale takes weeks or months and a sales team follows up on leads
- You use Claude or a similar AI tool every day and can show something you built with it
- You live in North or South America and overlap with US Central hours
- You're on Slack during US Central business hours, reply in real time and write clear, fluent English
- You work from a shared task list, report back on what you finished, and turn repeat tasks into automations
- You work as an individual, not through an agency

## Hours and pay for the B2B marketing systems builder role

**Contract. 10 to 15 hours a week to start. $60 to $90 an hour.**

It's fully remote and part-time, and the work starts as soon as the right person is found.

## How to apply for the B2B marketing systems builder role

Apply through the short form. It takes about 10 minutes, and every applicant goes through it, so please don't apply by DM or email. If your application fits, I'll reach out, tell you who the role is for and set up a short video call. Finalists do a short paid test at their own rate before anyone starts.
