GTM Engineering Working Student

Companies have invested billions into ERP systems.

And yet, most business decisions are still made the way they were in 1995: on fragmented data, manual exports, and Excel.

Finance teams spend five to ten days every month copy-pasting numbers, and four systems show four versions of the same revenue.

AI changes that.

At ARC, we are building the AI-native Finance OS: one platform that connects all of a company's systems, answers any question in seconds, finds errors before they cost millions, and automates reporting end to end.

Leading Mittelstand companies like Burmester, Pfanner, and Ferrotec, and PE firms like AUCTUS and GENUI, already run their finance on ARC.

Finance software is being rebuilt from the ground up this decade, and we intend to win the category.

We are a small, AI-native team in Berlin, fresh off our seed round led by 42CAP, growing revenue 10x since our pre-seed.

We build, experiment, and move fast, take real ownership, and keep a low-ego culture.

Aufgaben

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.

We sell an AI-native platform, so our own go-to-market has to run AI-native too.

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, Linked In, and phone, and keep them personal enough that a German CFO actually responds
• Connect and orchestrate our GTM stack (Hub Spot, 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
• Qualifikation
• What makes you a great fit
• 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 with smart and friendly people with (self-reported) low ego
• You want to work on-site 5 days a week in our new Berlin office
• You may not be a good fit if
• You need detailed instructions and shy away from taking responsibility
• You're not willing to deeply understand the product and the buyer behind your automations
• You're only interested in high-level "strategic" work
• You think GTM engineering means setting up one Zapier flow
• You've never built anything on your own initiative
• You prefer working remotely
• You prefer working with minimal collaboration
• You want to work a 9-5 job
