GTM Engineer

GTM Engineer @ Apex Fractional

Not a ticket executor and not a slide-deck consultant, but a builder: a Go-to-Market Engineer who ships AI-powered revenue engines to production and owns the client relationship around them.

Who are we?

We're Apex Fractional, a boutique, AI-first growth partner founded by serial entrepreneurs Tomek Nowiński, Marcin Pogroszewski and Maciek Bojczewski. Apex is where AI hits revenue. We work with high-growth companies, mostly US-based B2B SaaS above $10M in revenue, plus a growing group of Polish brands, and we turn AI into numbers a board recognizes: pipeline, AI visibility, CAC.

We don't sell software and we don't sell slide decks. We embed with the client, build, and ship to production in weeks, not quarters. Four service lines run on one operating system: AEO/SEO content engines, paid ads (Google, Microsoft, Meta, LinkedIn, Reddit), AI-led outbound and custom web experiences. We're an official AirOps agency partner, profitable, bootstrapped, and proud of it.

What that looks like in practice

• Guidewheel: blended CPA down from $328 to $120 while monthly leads tripled.
• Spot AI: #1 AI visibility in its category and 12.9x ROI on content.
• Luxury Presence: +$300K in won contract value from a single campaign, at $10 per lead.

How we got here

Our story began over a decade ago at Groupon Poland, co-founded by Tomek. Shortly after, Tomek and Marcin launched a successful marketing agency (Marketing Wizards, later sold to iProspect, part of the Dentsu Aegis Network), while Tomek and Maciek (that's me) built Travelist, a travel deals company later acquired by Secret Escapes.

Then our paths diverged. Marcin and Tomek became investors in several businesses, furthered their education at Stanford GSB, and added value to numerous VC-backed organizations worldwide. I spent a decade as COO/GM in Polish e-commerce ventures, contributing to multiple exits.

In 2022 our paths converged again in Apex. Today we're a small team of GTM Engineers and specialists, and we want to keep building a team we're proud of.

Your mission

We have the clients, the playbooks, and an operating system we built ourselves. What we need is one more GTM Engineer who can take a client engagement and run it: build the workflows, ship the campaigns and content, and be the person the client trusts on the weekly call.

This is a hands-on, revenue-focused builder role, not a traditional consultant or project manager position. You'll join a small team of GTMEs in a flat structure and work directly with the founders.

How we work

• AI-native, for real. Everything runs on Apex OS, our internal operating system: one repo holding every client's profile, brand dossier, meeting history, automations and reports, driven through Claude Code every day.
• Reuse over reinvention. Every build becomes a reusable skill or component. We hold ourselves to 50%+ component reuse, so the fifth workflow ships much faster than the first.
• Production, not prototypes. Content engines run on AirOps, campaigns run in the client's own ad accounts, and the client owns what we build.
• You don't need to be a software engineer, but you'll be comfortable in a terminal, with Git and pull requests, and with an API that returns something unexpected.
• Small team, big ambition. We're a talented team with big ambitions: we help and support one another, and grow together.

What you'll do

• Own client engagements end to end: from understanding the funnel, data and tools to shipping and running the work. You'll start with two or three and grow from there.
• Build AI workflows and automations across the client's stack (HubSpot or Salesforce, GA4 and GTM, ad platforms, Webflow or WordPress, the warehouse) with Claude Code, AirOps and whatever tool is best for the job.
• Experiment with discipline: hypothesis, test plan, success signal, honest readout.
• Lead the client rhythm: weekly live calls, daily Slack, and biweekly check-ins that produce decisions, not status updates.
• Translate outputs into what the client's CEO or CMO cares about: pipeline, CAC, AI visibility.
• Compound our library: turn what you build into reusable skills and document it so a teammate can pick it up cold.
• Scout new tools, test them, and decide what's worth adopting.

You're a great fit if you

• Have min. 3 years of professional experience in growth, performance marketing, marketing ops / RevOps, analytics, or consulting.
• Are a hands-on builder: you've automated real work end to end (Make, n8n, Zapier, Clay, AirOps, scripts or similar), you understand APIs and data, and you know how tracking works.
• Use AI tools daily and can show us what you built, where it broke, and how you fixed it.
• Read numbers properly: CPA, conversion rate, attribution. You notice when a number doesn't add up.
• Are fluent in English and Polish, written and spoken. Most of our clients are in the US, a growing part are in Poland.
• Communicate clearly and confidently with senior stakeholders.
• Are diligent, take ownership of your work, and have a growth mindset.
• Can start in December 2026 or January 2027.

(We will only consider applications that check all of the above.)

Bonus points for

• Experience with Claude Code or other coding agents, or coding in any language (Python is a plus).
• Hands-on paid media (Google, Microsoft, Meta, LinkedIn) or conversion tracking (GTM, GA4, server-side, offline conversions).
• SEO / AEO and content systems at scale.
• Outbound tooling: Clay, Apollo, HeyReach, Instantly.
• Agency or consulting experience with managerial-level stakeholders.
• A background in science, engineering, IT, finance or math.
• A portfolio of AI side projects.

Our values

• Integrity: we do the right thing, even when no one is watching. Say what you think and do what you say.
• Diligence: we get stuff done and bring up solutions, not problems.
• Joy / Fun: we enjoy what we do, celebrate wins together, and find satisfaction in building things that actually work.
• Growth Mindset: we may not know everything, but we always figure it out. Feedback is a gift.

What we offer

• A very rewarding profit-sharing bonus system: when Apex wins, you win.
• A transparent career path: GTMESkills®, our framework of 20 competencies from day one to Senior GTME, monthly Growth Talks with a founder, clear promotion criteria.
