Full Stack AI Automation Engineer in United Kingdom

Full Stack AI Automation Engineer

Nobody hands you a ticket. You sit inside real US service businesses, find the work that should not be done by hand, and build the thing that removes it.

Remote · Latin America · $3,500-$4,500 USD/month · Full-time · Independent Contractor · Monday to Friday · 9 AM-5 PM ET

Why this role exists

Our client runs established US service businesses with real operations behind them: call centers, field teams, schedules, invoices, and customers who call when something breaks. They are not software companies, and that is the point. There is a lot of work happening today that a good engineer could automate, and nobody in house is going to build it.

What you'll own

• Sit with the operating team, learn the workflow, and identify what is worth automating

• Build and ship full stack applications and internal tools, end to end

• Build AI automations and agents on top of existing systems: phone, email, scheduling, CRM, billing

• Integrate systems that were never designed to talk to each other, through APIs, webhooks and databases

• Ship prototypes fast, put them in front of real users, and iterate on what comes back

• Keep what you build running, and document it well enough that the business is not dependent on you being awake

• Explain your work to people who are not technical, and say no when an idea is not worth building

Why this is interesting

• The problems are real and the constraints are real. Not a backlog someone else wrote, and not a demo. Things that break when they break

• Full stack plus LLMs plus whatever the integration needs. You pick the tools and you own the call

• You work across more than one business, so you learn to get to the real problem fast and ship something useful before anyone loses interest

What we're looking for

• 4 or more years building software end to end, frontend and backend

• Strong in TypeScript or Python, comfortable with APIs, databases and cloud deployment

• Real automations built with LLMs, not demos. OpenAI, Claude or similar, wired into systems people actually use

• n8n, Make, Zapier or your own code to connect tools that do not integrate

• AI coding tools used every day as part of how you build

• Strong English in speech and writing. You can sit in a call with a business owner and come out with the right problem

• You ship. You have built and launched things on your own, and you would rather have something working on Friday than perfect in a month

Bonus

• Service businesses: home services, field operations, call centers, logistics

• Telephony or voice AI platforms

• You have been the only engineer on something and it survived

• Data pipelines or reporting on top of operational systems

What success looks like

First 90 days

• By day 30 you understand how the business runs and you have shipped your first automation, small but in production

• By day 60 you have delivered something the team uses daily and you are bringing your own list of what to build next

• By day 90 there is work that used to take hours a week and now takes none, and the owner can name it

Ongoing

• You find the problems yourself instead of waiting for a ticket

• What you build stays running and other people can maintain it

• The business measures the hours you gave back, and the number keeps growing
