Hire an AI automation engineer, a freelancer or an agency?
By the Codivated team · Updated
Hire an in-house AI automation engineer when you have a steady backlog of automation work and someone senior to direct it. Use a freelancer for one well-defined automation. Use an AI agency or consultancy when you need someone to decide what to build, build it to production, and stay accountable for results. Many companies hire a person to fix what is really a missing system or a missing plan.
Why is this decision so common right now?
Because "AI automation engineer" has become a catch-all. In our review of recent public job posts from companies hiring for AI work, many asked for one person to map every workflow, pick the tools, build agents in n8n or code, connect the CRM and ERP, and train the team. That's three jobs: strategy, engineering and change management. A single hire rarely covers all three.
How do the options compare?
| In-house engineer | Freelancer | Agency or consultancy | |
|---|---|---|---|
| Best for | A steady, long backlog of automation work | One defined automation with a clear spec | Deciding what to build and shipping it to production |
| Who decides what to build | You | You | Shared; they should push back |
| Time to start | Months to hire | Days | Weeks |
| Accountable for results | Through management | For the deliverable | For the outcome, if the contract says so |
| Watch out for | Hiring before you know what you need | Hand-off with no one to maintain it | Strategy decks with nothing running |
When should you hire in-house?
When automation is now a permanent part of how you operate, you have at least a year of work queued, and someone senior can set priorities and review the work. A good first in-house hire often comes after an outside team has built the first agents and the patterns: the hire then extends something that works instead of starting from a blank page.
When is a freelancer the right call?
When the job is clear and contained: "when a form comes in, create the record, enrich it and notify the rep", built in n8n, Make or Zapier. Write the spec, agree how it's tested, and make sure the credentials and the workflows live in your accounts, not theirs. Our n8n vs custom agent guide helps check whether the job fits a workflow tool.
When do you need an agency or consultancy?
- You don't yet know which workflows are worth automating, or in what order.
- The work touches your core systems, customers or money, and needs approvals, logging and testing.
- You want agents in production in weeks, with someone accountable if they don't work.
- You need your team trained and the workflow redesigned, not just a build.
What should you ask before hiring anyone?
- What have you put into production that people still use, and what broke?
- How will you test it before it touches real work?
- Who owns the accounts, code and workflows when you're done?
- Which actions will need a person's approval, and how will that work? (See human in the loop AI agents.)
- How will we know it worked: what number, measured how?
Should you pay by the hour?
For a person on your team, yes. For an outcome, usually not. When one experienced builder runs many agents in parallel, hours stop matching value. Fixed-scope projects for builds, and a retainer for ongoing advice and care, line up the incentives better. That's how we work: an advisory retainer for priorities and roadmap, with builds priced as fixed-scope projects.
Common questions
What does an AI automation engineer do?
Builds and maintains automations and agents: connecting tools, writing the workflows or code, adding AI steps, and keeping them running as your systems change.
Can one person run our whole AI program?
Rarely at first. Strategy, engineering and adoption are different skills. A fractional AI leader plus builders often fits better; see fractional chief AI officer.
How do we avoid getting locked in to an agency?
Keep everything in your accounts, require documentation and a handover, and make sure your team can see and change the rules the agents follow.
