Senior Account Manager / Customer Success Manager (m/f/x)

About Tendos

Tendos is the AI platform for manufacturers in the construction industry. We are redefining how sales and tender processes work: from finding the right projects to processing inquiries, creating quotes and entering orders. Our AI agents run these processes end to end, including the complex steps that used to depend on a few experts, and the platform gets better with every action. We are live with leading manufacturers across Europe and process quotes worth billions of euros. Inside sales is where we started; the platform and the markets we serve are expanding. We are a team of around 20 in the heart of Munich, venture-backed, and we work AI-first: every function automates its own back office. Construction is the biggest industry in the world, and it still runs on manual sales work. We are changing that.

The role

Account Management and Customer Success are one role at Tendos. You own existing accounts after the sale: customer projects, adoption, account health, the relationship with the customer's management, renewals and expansion into new modules, teams, sites and countries. Solution Engineering owns the technical setup; you own the number. You are the customer’s advocate inside Tendos and the customer’s strategic advisor on AI.

What you'll do

Own a portfolio of existing accounts, including the largest, and grow adoption & value in every one.

Build expansion cases from the customer's own numbers, presented on management-/c-level

Run customer projects with owners and dates, and make the plan hold.

Track account health with a real process, spot risks early and bring an action plan before anyone asks.

Bring account signals to Product as patterns, not single feature requests, and align internally before committing to customers.

Shape the account playbook the AM team runs on.

Run account management AI-first: meeting prep, follow-ups, account reviews and reporting are automated wherever possible, with the quality bar your customers' management expects. No AI slop.

What you must bring

Senior B2B AM or CSM in Software.

You have personally owned and closed six-digit renewals: your number, your close.

Credibility with management at German industrial manufacturers, from inside sales leads to managing directors. You understand how Mittelstand companies decide.

Commercial backbone: you own a number and negotiate commercial terms with management, procurement and IT.

An ownership reflex: you create structure instead of waiting for it, flag capacity early and ask for help early.

Translate between the customer's management and our Tendos: you understand enough about data, integrations and AI to frame the conversation & know when to bring the internal experts in.

Curiosity for how the industry works. We teach the domain.

AI-first as a habit: you automate your own back office, and you can tell good AI output from plausible-looking junk.

Munich on-site. German at native level (C1+) and fluent English; customer meetings run in German. Further languages help for rollouts across Europe.

What we offer

We'll treat you well. If other benefits matter to you, tell us.

Salary and equity: a competitive base salary plus real shares in Tendos through our employee incentive plan (EIP), with the most favorable tax treatment (up to 30% tax reduction).

Real ownership: you own outcomes, not tasks. Short paths to the founders; decisions are made with you, not for you.

An industry worth changing: bring the biggest industry in the world into the AI era.

AI-first by default: the tools, the budget and the mandate to automate your own work.

Central office at Königsplatz, Munich. We work together on-site.

Wellpass membership: gyms, pools, yoga and sports across Germany.

Team culture: regular team events and offsites, transparent communication, a super senior team that runs at full load and has each other's backs.

At Tendos, we are committed to building a diverse and inclusive team. We are an equal opportunity employer and welcome applications from all qualified candidates.
