Go-To-Market Engineer

Marketing
Zedelgem
Full-time
September 8, 2026

At Telsmart we make customer service ridiculously simple for businesses, through smart cloud telephony with a built-in AI assistant that works seamlessly with your CRM and your team.

We're a growing scale-up. Things move fast here and we have serious (international) ambitions. Marketing plays a key role in that.

Which is where you come in. You're the one who will build, fine-tune and run our go-to-market machine.

What will you do here?

You build systems that capture conversations.

You set up outbound campaigns that aren't spam, but relevant, personal, and on target.

You help sales create opportunities within our ICP faster, smarter, and more consistently.

Concretely, that looks like this:

  • You build and run outbound and prospecting campaigns with tools like Clay, Lemlist and HubSpot
  • You enrich prospect data and segments so sales can reach out with context and timing
  • You support sales reps and account managers with lists, flows, messaging and follow-up
  • You put HubSpot at the centre as the backbone of sales and marketing, from pipeline to reporting
  • You work in tandem with our Marketing Manager and the marketing team so all of this stays in line with our overarching strategy, paid campaign channels, and everything around them
  • You help think through ICP, buyer personas and new markets we could open
  • You help Telsmart open new regions and markets, with a focus on scalability
  • You continuously experiment, test and optimise on messaging, hooks and audience
  • You work closely with sales, marketing and leadership to keep our GTM strategy sharp

What will your week look like?

Monday you start by fine-tuning an outbound flow that already produced its first conversations last week.

You sit down with our Marketing Manager, sales and product to help shape our vision and our (marketing) strategy.

You analyse where prospects drop off, and sharpen the messaging or the targeting.

You build a new Clay table around a niche inside our ICP, conjure data enrichment and copy out of AI tools like Claude, ChatGPT and Breeze, and push the leads through your best-performing Lemlist sequence.

You set up HubSpot workflows that take manual work away from sales, and together with our Marketing Manager you keep everyone pointing the same way on HubSpot.

You spar with sales about which accounts feel warm, and how we could approach them more intelligently.

Who are you?

You're not a classic marketer, and not a pure sales profile. You sit in between, and that is exactly what makes you strong.

  • You think in systems, flows and experiments
  • You like tooling, data and automation
  • You understand how sales works and what a good lead is worth
  • You sense that outbound today only works when it's smart and relevant
  • You'd rather build something that keeps running than one standalone campaign

You'll also recognise yourself in this:

  • You find your way easily in HubSpot and understand pipelines, workflows and CRM logic
  • You have experience with outbound tools like Clay, Lemlist, Apollo, Smartlead or similar
  • You understand ICPs, segmentation and buyer intent
  • You work in a structured way, but you dare to test quickly
  • You communicate clearly with sales, marketing and tech
  • Experience in B2B or SaaS is a plus, but not a must

We have international ambitions too, so affinity with the Dutch market and its culture is an extra tick on your bingo card.

Why choose Telsmart?

  • We have serious growth ambitions and what you do here can genuinely make an impact. You're at the start of a growing marketing team, and you grow with it.
  • Ride the energy and drive of a team that doesn't go 100%, but 200%.
  • Connection and humanity genuinely matter here — just ask in our 'No Work Allowed' WhatsApp group.
  • Did we mention there are alpacas wandering around the garden…?!
  • Not convinced? How about pancakes at the office, kubb with the team, ice bath challenges, and team trips to Croatia?
  • We're not looking for perfect people. We're looking for people with goesting — the Flemish word for the appetite to actually go and do it.

Not in the mood for a boring marketing job? Good. Neither are we.

What do you get from us?

  • A competitive salary that grows with your impact and with the company.
  • A hybrid Renault company car, hospitalisation insurance, and additional cover through ALAN, with unlimited access to coaches and psychologists.
  • Meal vouchers and a cafeteria plan.
  • When things go well, everyone shares in it: a team bonus every quarter, based on target.
  • Room for training and personal development. We're happy to invest in anything that moves you forward.
  • We genuinely invest in you as a person: your personal development, your wellbeing, and appreciation for your work.
  • Stuck, or in need of extra coaching? You can lean on coaching from friends of the house who work in the agency world.
