Fractional GTM engineer in Australia. The outbound machine, built in code.

GTM is short for go-to-market: everything a business does to find customers and win them. A GTM engineer builds the machinery behind it. Clay, which coined the title in 2023, defines the practice as “building automated revenue systems using AI, data enrichment, and workflow automation”, and describes the role as an internal product team for sales and marketing: find the problem, ship a prototype, scale what works.

Day to day that means four kinds of work. Data: who is in your market, with the right contact for each company. Signals: the moments that make someone worth contacting now, such as a job ad, a funding round, a new location, a post they engaged with or a conference they are speaking at. Activation: sequences, LinkedIn and email copy that use those signals. And plumbing: replies routed into the CRM, suppression lists kept current, and reporting on meetings booked rather than emails sent.

Everett Berry, who runs GTM engineering at Clay, puts the build order as data quality first, then fixing broken processes, then new plays (GTM Council). I work the same way. Most outbound that “does not work” is a list problem.

The titles overlap, and plenty of people hold two of them. The useful difference is what each one is measured on.

Partly. Sales ops people have been gluing tools together for years, and some of what is sold as GTM engineering is a Clay table with a nicer invoice. Kyle Poyar found more LinkedIn posts about the role than companies hiring for it: for every GTM engineer job ad there were 14 RevOps ads and 92 SDR ads, and about 45% of people with the title work at agencies or as consultants (Growth Unhinged).

What is new is the cost of building. A list that took an SDR a fortnight now takes an afternoon of agents and a few dollars of data, and a script can rebuild it on the morning of the send. So the work has moved from operating tools to building small systems, and that is a different skill from running a CRM. Postings agree: Bloomberry found SQL and Python in 38% of GTM engineer job ads and new postings up 205% year on year (Bloomberry).

Most GTM engineering content is written by tool vendors, so it assumes their tool. I build most systems as scripts and agent workflows in Claude Code, connected to Apify for scraping, Apollo for contact data, Smartlead or Instantly for email, Waalaxy for LinkedIn and GoHighLevel or HubSpot as the CRM. The scripts live in your repository, so the system keeps working when the engagement ends and nobody is paying for seats they do not use.

Australian data is thinner than the US data these tools are built on. Small Australian firms are often missing from Apollo, and directories hold the business but not the person. That is why the schools build started from the sector body’s own directory and why the strata build targeted firms. The best list for your market is usually one nobody sells.

Cold email in Australia also has to meet the Spam Act 2003: a business reason to contact the person, clear identification of who is sending and a working unsubscribe. I send from a separate domain, keep one do-not-contact list across every tool and keep sequences short and reply-led.

It all connects to the rest of the funnel. Outbound works better when the website, the ads and the content say the same thing, which is the marketing engineering half of the same job.

An in-house GTM engineer in Australia is advertised at roughly A$120k to A$150k, with senior hires at A$175k to A$220k plus 12% super (SyncGTM estimate, 2026). US data is deeper: Bloomberry puts the median at US$127.5k and Getcargo at US$159k across 509 postings. Add tools and data credits and a full-time hire is a A$170k to A$250k a year decision.

My retainer is flat, from $1,500 a month. Tools and data (Apify runs, Apollo credits, sending platforms) are billed at cost and sit in your accounts. The first month is a paid trial: if the first system is not live within 30 days, you can walk away and I refund the retainer.
