Who We Are

Resilens is dedicated to solving one of the urgent challenges of our time: enabling communities and cities to adapt to a changing climate. Not everything can be prevented - but effective adaptation reduces losses and protects people where it matters most.

Our clients are city leaders and private operators who will use our climate adaptation platform to move from uncertainty to evidence-based action. We’re a data-first company combining domain expertise with modern technology. We turn climate risk into ranked measures and fundable priorities - with clear numbers on risk, cost, and expected impact. We’re looking for hands-on builders who want to join us in making adaptation happen. 

How we work: We believe regular in-person collaboration matters in an early-stage specialist team. We work in a hybrid setup with regular in-person collaboration. We typically expect 50%+ in-office presence in Potsdam, including 1–2 fixed team days per week. English is our working language. German is a plus.

What you’ll do

As our Founding Sales & Customer Success Manager, you will help build the commercial foundation of Resilens from the ground up. You will work across the full customer journey: from first inbound interest and demo preparation to follow-up, trial coordination, onboarding, early customer success, and commercial process building.

This is a highly cross-functional role for a hands-on builder. You will work closely with the founders and help turn founder-led go-to-market activities into repeatable workflows, clear customer handovers, strong follow-through, and a high-quality customer experience.

We see this as a foundational commercial role with clear potential to grow into a future leadership position, depending on company needs, traction, and individual performance.

Your responsibilities will include:

• Preparing and delivering product demos for prospects and early customers

• Supporting founders in high-priority commercial conversations and follow-ups

• Managing inbound leads, qualifying opportunities, and coordinating next steps

• Driving disciplined follow-up after demos, meetings, and early commercial interactions

• Coordinating trial setup, activation, and customer engagement during the trial period

• Supporting onboarding and helping customers reach first value quickly

• Serving as a reliable point of contact for selected prospects and early customers

• Capturing customer feedback, objections, and requests and feeding them back internally to optimize the product

• Maintaining CRM hygiene, pipeline visibility, and commercial reporting

• Creating templates, playbooks, FAQs, and lightweight processes for demo, onboarding, and customer communication

• Helping us define what should become standard support material, product improvements, or internal workflows

What success looks like in your first 6–12 months

• A reliable lead-to-trial-to-onboarding workflow is running in HubSpot, with clear stages, ownership, and visibility.

• Qualified prospects move forward through strong demos, disciplined follow-up, and clear next steps.

• Early customers are activated smoothly and reach first value faster through structured onboarding.

• Founder-led commercial activities have been turned into repeatable playbooks, templates, FAQs, and reporting.

• Core commercial metrics are in place, target benchmarks are defined, and progress is reviewed regularly.

What we’re looking for

• You have the right to work in the EU.

Must haves

• 4+ years of experience in a customer-facing role in B2B or B2G SaaS, climate tech, gov tech, urban tech, data products, or a similarly consultative software environment

• Strong ability to run customer conversations with confidence, clarity, and credibility

• Experience with demos, onboarding, account management, customer success, solutions, or hybrid commercial roles

• Excellent follow-through and high operational discipline

• Ability to manage multiple customer and internal workstreams in parallel

• Strong written and verbal communication skills in English

• Builder mentality: you are comfortable with ambiguity, create structure proactively, and enjoy helping shape new ways of working

• Good commercial judgment and a strong instinct for how customer interest turns into trust, progress, and buying momentum

• Genuine willingness to work hands-on across role boundaries in an early-stage company

Nice to haves

• Experience selling or onboarding into public sector, infrastructure, real estate, energy, insurance, or other complex stakeholder environments

• German language skills

• Experience with HubSpot or similar CRM systems

• Previous startup experience in an early-stage environment

• Interest in growing into a future commercial leadership role

How We Work

• We care about climate adaptation and tangible, on-the-ground impact

• We don’t wait for perfect plans: We define outcomes and flag risks early

• We learn fast and turn that learning into real outputs

• We separate our ego from our ideas and update our beliefs when presented with better evidence

What We Offer You

We offer the chance to build a category-defining product alongside experienced people who have pioneered this field before.

• Direct Impact: Work on the core of a product that changes how cities and operators will handle the climate crisis.

• Experienced team: We are led by a founding team with 20+ years of experience each across climate analytics, scalable software, and building companies. 

• No drama, no egos. We value evidence over impressions and respect over hierarchy.

• Room for Growth: We are a small team building an impactful product. This offers you a unique environment to master how complex climate risks are translated into real-world investable action.

• Aligned Autonomy: We agree on the "Why" and the outcomes, then you own the "How."

• Strong runway: We are financed for the next 3 years.

• Competitive compensation and possibly equity package.

Inclusive by Design: We believe diverse backgrounds and perspectives strengthen judgment and product quality. We evaluate candidates against consistent outcomes and competencies, and we encourage applications from all genders, backgrounds, and experiences. We look for genuinely kind collaborators who make our team better through empathy, candid feedback, and a shared commitment to excellence.
