About zerothird

At zerothird (zerothird.com), we're building the future of secure communications. As a fast-scaling quantum technology company, we specialize in entanglement-based Quantum Key Distribution (eQKD) - the most advanced, physically unbreakable encryption method available today. Based on Nobel-Prize winning research, our systems enable critical infrastructure, telecom providers, and enterprise customers to protect their networks against both today's threats and tomorrow's quantum attacks.

We're expanding and are looking for a high-performing Sales Executive to help us drive revenue and close strategic deals mainly in Germany and Austria, with a strong focus on critical infrastructure clients.

Key Responsibilities

You will take ownership of the full sales lifecycle - from identifying prospects to closing high-value enterprise and government contracts. As a core member of our growth team, you'll position our unique eQKD systems as must-have infrastructure for organizations seeking ultimate communication security.

This role has a strong focus on engaging customers in critical infrastructure sectors - including energy, utilities, public administration, transportation, and financial services.

• Confidently present zerothird's eQKD offering to both C-level and technical stakeholders
• Tailor proposals and demos to convert interest into clear business value
• Build strategic partnerships with distributors, resellers and technology partners

Deal Management & Closure

• Drive opportunities through all deal stages - from qualification to signed contract
• Take a lead role in pricing, negotiation, and deal structuring
• Work closely with technical, legal, and operations teams to remove friction and close deals faster
• Own and exceed quarterly sales targets

We seek

• Min. 5 years of B2B sales experience, ideally in enterprise tech, telecom, network- and cybersecurity
• Proven track record of closing deals and outperforming targets
• Strong communication and negotiation skills in both German and English
• Hunter mentality: self-driven, persistent, and highly organized
• Ability to understand and pitch technical products to business decision-makers
• Experience selling to critical infrastructure or regulated industries is a strong plus
• Willingness to travel regularly within Germany and Austria

Our offer

• High Impact: Join at the intersection of Nobel-Prize winning quantum physics and secure communications - and help shape solutions that will protect global infrastructure for decades.
• Vibrant Quantum Community: Join a young and ambitious team with a strong spirit of collaboration, regular team-building events, and a shared passion for meaningful tech. Enjoy rooftop coffee breaks overlooking Vienna's Wienerberg.
• Family-Friendly Workplace: We support flexible schedules and work arrangements to help you balance your professional drive with personal priorities and family duties.
• High-Growth Opportunity: Be part of one of the most exciting sectors in deep tech. As demand for quantum-secure communication accelerates, you'll have the opportunity to shape new markets - and grow with us.
• Inclusive Culture: We believe in "Duz-Kultur", flat hierarchies, and fast, transparent communication.
• Targeted Onboarding & Learning: You'll receive a tailored onboarding and a dedicated mentor to help you ramp quickly and succeed. Stay sharp with access to training, coaching, and market insights.
• Extras That Count: Enjoy premium coffee, fresh fruit, team lunches, and summer & holiday events when working from our Vienna HQ.
