We're hiring aSenior Sales Development Representative to help build Timefold’s outbound motion in North America.

About the role

AI didn't kill the SDR role. It killed the average one. The ones who survive — and win — are the ones who figured out how to use AI as a force multiplier rather than a shortcut.

This is not a high-volume, spray-and-pray prospecting role. Timefold sells a technical platform into companies where scheduling, routing, and optimization are commercially important. Good outbound therefore starts with understanding the account, identifying the right trigger, and creating a relevant reason for the right person to speak with us.

You will work closely with Account Executives, Marketing, and Solutions Engineering to create qualified conversations in target accounts. You will focus on software vendors, OEMs, and technically mature organisations with complex planning problems.

The SDR owns the work before the opportunity: account research, outreach, early qualification, and a clean handoff to Sales. The Account Executive owns the opportunity and commercial process once it is qualified.

This role reports to the Head of Sales.

What the role looks like

Build qualified outbound demand

• You dig into target accounts and prioritize them based on ICP fit, relevant use cases, company context, product or open-source adoption signals, and commercial potential — no spray-and-pray here.

• You catch the signals that actually matter: hiring sprees, funding rounds, product launches, tech stack changes, content engagement, or operational complexity that screams "we need this."

• You map accounts like a detective, pinpointing the technical, operational, and executive stakeholders who actually move the deal.

• You run outreach that doesn't feel like outreach — tailored messages across email, phone, LinkedIn, and the communities where our audience actually hangs out.

• You turn conversations into qualified meetings and Sales-accepted leads that AEs are genuinely excited to pick up.

• You keep HubSpot squeaky clean — contacts, activity, source, lead status, and qualification data, all accurate, all the time.

• You share the playbook, openly: what messaging lands, what objections keep popping up, which personas and signals convert, and which account segments are worth chasing.

• You team up with Marketing, trading campaign feedback, outbound insights, and content ideas that actually make prospects lean in.

• You help shape Timefold's outbound motion as we scale — this isn't a role where you follow a script, it's one where you help write it.

Craft outreach for technical buyers

We are targeting developers, architects, engineering leaders, product leaders, and data teams — that means you'll touch upon genuinely complex planning and optimization problems, not just the buzzwords around them.

• You engage operational and executive stakeholders with messaging tied to business outcomes: service quality, operational efficiency, scheduling complexity, growth, and build-versus-buy decisions.

• You know the difference between a technical evaluator, a champion, an operational stakeholder, and the economic buyer — and you flex your approach accordingly, because one-size-fits-all pitches don't work on people who solve hard problems for a living.

• You treat open-source and community signals as a research starting point, not a shortcut — you validate relevance before ever mistaking interest for intent.

Convert & engagement

Success is not measured only by emails sent or meetings booked.

• Meaningful engagement in target accounts —
