Our AI-native platform unifies protection across endpoint, cloud, identity, data, and AI systems to deliver autonomous detection and response with clarity and speed. By combining real-time analytics, intelligent automation, and a unified data foundation, we reduce noise, simplify complexity, and empower security teams to focus on what truly matters.

Our teams are builders, problem-solvers, and innovators committed to shaping the future of security. If you are excited to solve hard problems alongside talented, mission-driven people, we invite you to help us build a safer future for humanity.

What Are We Looking For?

We’re looking for people who are relentlessly curious and committed to continuous learning. AI is reshaping every function across our business, and we enable every team member, regardless of role or level, to build fluency in AI tools and concepts. Those who thrive here actively seek out new solutions, experiment thoughtfully, and apply what they learn to drive better, faster, smarter outcomes.

As a Commercial Solutions Engineer, you will work with commercial prospects and customers across Eastern Europe, aligning their goals and requirements with SentinelOne's offerings across prevention, XDR, and threat hunting. You will play an instrumental role in accelerating our sales initiatives, partnering closely with the sales team to design and propose security solutions that address the unique challenges of our customers.

What Will You Do?

Primary responsibilities include:

• Work closely with our sales team to design and propose security solutions that meet the unique needs of commercial customers across Eastern Europe, applying technical and commercial expertise to address diverse cybersecurity challenges and creatively resolve issues.
• Lead the Proof of Concept lifecycle from delivering demos through to technical closing, demonstrating strong problem-solving and analytical skills, and provide first and second-level technical support throughout the sales cycle.
• Develop and showcase a deep understanding of SentinelOne's products and solutions, aligning technical capabilities with customer needs and pain points, and deliver engaging security workshops and demonstrations to both technical and executive audiences.
• Collaborate with the channel, covering partner networks and engaging with selected enterprise customers, while providing valuable feedback to product management on product features and market trends.
• Demonstrate objection handling and competitive positioning skills across a range of customer engagements, communicating effectively with CxO-level, technical, and non-technical stakeholders as part of the broader EMEA team.

What Skills and Knowledge Will You Bring?

Ideal candidates will have:

• Fluency in English, with 3 to 6 years of experience in pre-sales within the cybersecurity industry and a proven track record of successfully selling to large customers and managing complex, competitive sales cycles.
• Strong technical depth across endpoint security, XDR, and threat hunting, with good knowledge of hacking and exploitation tools and methodologies, detection evasion techniques, and notable malware and anti-malware solutions.
• Demonstrable experience speaking to both small and large audiences, with excellent presentation skills and the ability to lead business and technical presentations, demonstrations, and conversations with executives and technical practitioners alike.
• A team-focused approach, positive attitude, and the ability to work effectively both independently and as part of a larger EMEA team, with a high level of technical curiosity and a passion for emerging technologies across endpoint, mobile, and cloud.
• Experience in computer forensics, security architecture, penetration testing, red teaming, or incident response is a plus.
