Work Location: In person

You will own the end to end implementation and operation of AI powered outbound campaigns for our clients. That means taking a client brief, understanding their target market, building the systems that research and engage prospects, and making sure those systems run reliably without hand holding.

This is not a "connect two Zapier steps and call it automation" kind of role. You will be designing multi step workflows where AI agents research companies, enrich data through APIs, personalize messaging intelligently, and deliver outputs into client tools. Each campaign is a custom system with moving parts that need to work together cleanly.

What your weeks will look like:

You will onboard new clients, understand their ICP and outreach goals, then build and deploy the technical infrastructure to execute those campaigns. You will monitor live campaigns, troubleshoot when something breaks, and optimize for better results over time. You will hop on video calls with clients when needed, but the bulk of your time is building and maintaining systems that work.

Specifically, you will:

Build and manage complex n8n workflows that pull data from multiple sources, enrich it through APIs and AI, and deliver personalized outputs. Design Airtable bases that structure client data, automate processing, and integrate with external tools. Set up and manage email infrastructure: domains, deliverability, sending sequences. Use AI tools (Claude, GPT) to build research and personalization layers into client workflows. Handle client onboarding, ongoing communication, and technical troubleshooting. Own your campaigns. When something breaks at 2 PM on a Tuesday, you fix it. When a client asks why response rates dropped, you investigate and have an answer.

Who This Is For

You are someone who figures things out. You read documentation, test until it works, and do not give up when the first approach fails. You have strong technical intuition even if you are not a traditional developer. You understand how APIs work, how data flows between systems, and how to debug when something is not behaving as expected.

You follow AI developments closely. Not casually. You know the practical performance difference between Claude Opus 4.6 & GPT 5.4 🙃, you have opinions on which tools are overhyped, and you have probably built something with AI that you are proud of, even if it was just for yourself.

You are hungry. Not in a cliché motivational poster way. You genuinely want to get better at what you do, you take ownership of your work, and you do not need someone checking in on you every few hours to make sure you are making progress.

Core skills (non negotiable):

• n8n: You have built workflows and understand how nodes, data flow, and error handling work.
• AI tools: Regular, meaningful use of Claude or ChatGPT. You know how to prompt effectively and understand the limitations.
• Technical aptitude: You pick up new tools fast and figure things out from documentation, not tutorials.
• English proficiency: Written and spoken. You will be communicating with international clients.

Great to have (you can learn these on the job):

Experience with cold email and outbound systems (Smartlead, Instantly, or similar). Understanding of email deliverability (SPF, DKIM, domain setup). API integration and webhook experience. Data enrichment workflows using tools like Apollo, web scraping, or similar.

Work Setup

Fully remote. Work from anywhere. 5 day week. You manage your own schedule as long as the work gets done and you are available for client calls when needed.

Why This Role Is Different

You are not joining a company to work on traditional endangered tech job, but working with AI all day long, and deploying it's outbound systems for clients. You are building and running AI infrastructure for organizations that most people only see on TV. The problems you solve are genuinely novel. There is no tutorial for most of what we do. You will learn faster here in 3 months than you would in years at most places, because we operate at the intersection of AI, automation, and high stakes client work.

If you are the kind of person who gets excited about building systems that actually work in the real world, not just demos, this is your role.

How to Apply

If you have a portfolio of n8n workflows, Airtable bases, or any AI projects you have built, include links. We value what you have actually built over what is listed on your resume. Practical proof of work is valued 100x than just writing cool things in your application.

AVOID WRITING USING AI ANYWHERE IN YOUR APPLICATION. WE WORK WITH AI ALL DAY. ANY APPLICATIONS WRITTEN USING AI WILL NOT BE READ AND WILL BE REMOVED BY OUR AI QUALIFIER AGENT ITSELF 🙂
