Job description

Senior Cybersecurity Sales Engineer - €190K OTE + Equity — Remote

This Sales Engineer role at Horizon3 sits at an exciting intersection of technical cybersecurity expertise and revenue-generating sales — a highly valued combination in today's market. The 70/30 OTE split (€112,000–€133,000 base, €48,000–€57,000 variable) is competitive for senior pre-sales roles in the DACH cybersecurity market, where comparable positions typically range from €100,000–€150,000 OTE.

• Deep hands-on knowledge of autonomous pentesting and attack surface management — fast-growing sub-sectors of cybersecurity.
• Enterprise sales engineering skills: POC design, RFP/RFI response, stakeholder communication.
• Cross-functional influence: bridging product, engineering, and go-to-market teams.

Green flags: Horizon3 is a funded, fast-growing startup with a clear product-market fit (NodeZero is deployed across government, enterprise, and MSSP channels). Equity (stock options) is included, which could be meaningful if the company is on a growth trajectory toward acquisition or IPO. The role offers visibility across the entire sales cycle, which accelerates career development faster than pure technical roles.

Potential considerations: The 50% travel requirement is demanding and could affect work-life balance. As an early-stage international team member (Germany market), you may have less structural support than at an established enterprise vendor. Culture is described as "learn-it-alls" — expect a fast pace and high ownership expectations.

Career path: This role positions well for a move into Regional Sales Director, VP of Sales Engineering, or even a CISO advisory career track over 3–5 years.

Get to Know Us

Horizon3 is a fast-growing cybersecurity company dedicated to the mission of enabling organizations to proactively find, fix, and verify exploitable attack vectors before criminals exploit them. Our flagship product, the NodeZero™ platform, delivers production-safe autonomous pentests and other key assessment operations that scale across the largest internal, external, cloud, and hybrid cloud environments. NodeZero has been adopted by organizations of all sizes, from small educational institutions to government agencies and Global 100 enterprises. It is used by ITOps/SecOps teams, consulting pentesters, and MSSPs and MSPs.

We are a fusion of former U.S. Special Operations cyber operators, startup engineers, and formerly frustrated cybersecurity practitioners. We're committed to helping solve our common security problems: ineffective security tools, false positives resulting in alert fatigue, blind spots, "checkbox" security culture, cybersecurity skills shortage, and the long lead time and expense of hiring outside consultants. Collectively, we are a team of learn-it-alls, committed to a culture of respect, collaboration, ownership, and results.

What You'll Do

Horizon3 is looking for a passionate Sales Engineer to join our team and help prospects and clients understand the true value and capabilities of our products and services.

• Technical Expertise: Demonstrate deep knowledge of our cybersecurity products and services, assisting the sales team in presenting and positioning them to prospects and clients.
• Customer Engagement: Meet with potential customers to understand their cybersecurity needs, challenges, and infrastructure, ensuring our solutions are the perfect fit.
• Product Demonstrations: Provide live demos and proof of concepts for our cybersecurity solutions, tailoring each demo to the specific needs and concerns of the potential customer.
• Solution Development: Work closely with the sales and product teams to design and refine solutions based on customer needs.
• Technical Training: Train the sales team on the technical aspects of our products to enhance their ability to sell more effectively.
• Feedback Loop: Relay feedback from the field to our product and engineering teams, contributing to the ongoing improvement of our product.
• RFP/RFI Assistance: Assist in answering technical sections of RFPs and RFIs.
• Post-Sales Support: On rare occasions, assist in post‑sales processes to ensure smooth implementation and customer satisfaction.

What You'll Bring

• Bachelor's degree in computer science, IT, cybersecurity, or a related field. Advanced degree(s) are a plus.
• 5+ years of experience as a Sales Engineer, ideally in the cybersecurity domain.
• Strong understanding of cyber threats, risk management, and cybersecurity solutions.
• Excellent verbal and written communication skills.
• Demonstrated ability to simplify complex technical topics for a non-technical audience.
• Highly collaborative with a strong sense of initiative.
• Business-level German and fluency in English required.
