Responsibilities:

• Manual functional, regression, and integration testing of the web service and related systems.
• Collaboration with developers and the product team to clarify requirements and testing scenarios.

What we expect:

• Support of legalization in Slovakia if needed.

   

The Role

In this role, you’ll own opportunities from demo through signed contract, driving deals forward and closing business.

Inbound and outbound pipeline generation are handled separately, so you’ll work with qualified, demo-ready opportunities. During ramp-up, demos are led by senior leadership; you’ll quickly transition to running them independently and owning the process through close.

You’ll manage the full commercial path: follow-ups, pilots, negotiations, proposals, and contracts. No cold prospecting. Clear ownership and direct access to leadership.
 

What You’ll Own

• Own deals from demo through signed contract
• Lead product demos independently once ramped, with support from senior leadership as needed
• Drive timely, structured communication with prospects and decision-makers
• Coordinate pilot and evaluation stages — manage timelines, stakeholders, and next steps
• Manage objections, commercial discussions, and negotiations
• Prepare proposals, pricing, and deal documentation
• Maintain accurate pipeline data in HubSpot — stages, tasks, forecasts, and notes
• Collaborate with product, engineering, and account management to support deal requirements
• Ensure a clean handoff from closed-won deals to customer success
• Share structured prospect feedback to improve positioning and conversion
   

What We’re Looking For

• 3–5+ years in a quota-carrying, deal-closing role in B2B SaaS (e.g., Account Executive, Sales Manager, Business Development, or similar)
• Proven track record closing deals in the $30K–$60K+ range
• Background in AI, health tech, fitness tech, or technical SaaS
• Experience with US or European mid-market or enterprise clients
• Experience managing multi-stakeholder sales cycles of 2–6 months
• Experience running demos and managing pilot or proof-of-concept stages
• Fluent English, spoken and written — C1/C2
• Strong HubSpot proficiency — pipeline management, sequences, forecasting
• Disciplined follow-up and CRM hygiene
• Autonomous and structured — able to move deals forward independently
   

What Success Looks Like in the First 90 Days

You’ve taken ownership of the active pipeline, established a clear operating rhythm in HubSpot, and built a reliable view of deal status, next steps, and accountability across all open opportunities. Deals are progressing consistently, with no gaps in ownership, follow-up, or momentum.

• Strong understanding of network security, web application security, and infrastructure security.
• Experience conducting penetration tests or security research.
• Familiarity with Linux systems and common server environments.
• Ability to analyze systems and identify weaknesses in architecture or implementation.
• Curiosity, persistence, and a strong desire to understand how systems fail.
• Ability to configure and maintain system-level firewalls (for example, iptables, nftables, or ufw) and enforce network-level access policies.
• Experience configuring and operating Web Application Firewalls (WAFs) such as Cloudflare WAF, ModSecurity, or similar solutions to protect APIs and web services.
• Strong practical understanding of how the Internet works, including DNS, TLS, HTTP, and common attack vectors affecting networked systems.
• Solid knowledge of networking fundamentals, including TCP/IP, routing, NAT, VLANs, and the OSI model.
• Ability to analyze traffic flows, understand how packets move through networks, and diagnose connectivity or security issues across different layers of the network stack.

Relevant certifications such as OSCP, CEH, Security+, or similar are welcome, but real-world experience and demonstrated skills matter more.

Who We Are Looking For

Not looking for someone whose experience is centered primarily on managing large security teams or producing compliance documentation.

Instead, we are looking for highly motivated engineers and curious security-minded builders who enjoy exploring systems, testing assumptions, finding weaknesses in creative ways, and building stronger defenses as a result. Unusual backgrounds, unconventional experience, and self-driven experimentation can be a better fit for this role than a traditional career path.
