GTM Engineering Working Student

You are the GTM Engineering Intern at ARC. While our BDRs are on the phone with CFOs, you build the machine behind them: the automations, data pipelines, and AI workflows that decide who we call, with what message, and when. You'll build our internal GTM OS from the ground up.

What you'll do

• Build automated prospecting pipelines: sourcing multi-entity Mittelstand groups and PE-backed companies that fit our ICP, at scale
• Enrich accounts and contacts with the signals that matter to us: legal entities, ERP landscape, PE ownership, trigger events like ERP migrations or acquisitions
• Automate outreach workflows across email, LinkedIn, and phone, and keep them personal enough that a German CFO actually responds
• Connect and orchestrate our GTM stack (HubSpot, Aircall, enrichment and outreach tools) into one system with clean data flowing through it
• Use AI models aggressively: for research, list building, message drafting, call analysis, and anything else that removes manual work from the pipeline
• Build dashboards and KPI tracking so we always know what's working in outbound and what isn't
• Prototype, test, and iterate: your experiments directly shape how ARC's GTM engine works as we scale the sales team

What you'll need

• You love building things: with no-code tools, scripts, APIs, or AI agents, whatever gets it done fastest
• You're deep in the modern AI tool stack and use LLMs daily as a matter of course
• You're analytical and rigorous with data: messy lists and broken syncs bother you until they're fixed
• You have strong business sense and can think from the prospect's perspective, not just the pipeline's
• You're hands-on and not afraid of unglamorous work: cleaning a CRM included
• You communicate well in English; German is a plus since our market is the German Mittelstand
• You want to work on-site 5 days a week in our new Berlin office
