You will be a key partner to the Enterprise go-to-market teams to review, negotiate, and close commercial agreements, with a focus on efficiency, consistency, and enabling deal velocity. Enterprise customers require an experienced negotiator who can deal with complex issues and protect Horizon3 while balancing the needs of a sophisticated customer base.

This is a hands-on, business-facing role where you’ll build strong relationships with Sales and cross-functional partners, apply practical judgment, and contribute to improving templates and processes as the company scales.

What You’ll Do:

Commercial Transactions

• Draft, review, and negotiate a high volume of enterprise-focused commercial agreements, including:
  • NDAs, SaaS subscription agreements (MSAs), order forms, and DPAs
  • Evaluation and trial agreements
• Support Sales and Customer Success teams in closing deals efficiently while aligning with company risk guidelines
• Review and respond to customer contract requests, including redlines on standard agreements and occasional customer paper

Deal Support & Execution

• Partner closely with Sales and RevOps to keep deals moving and unblock contract-related issues
• Support enterprise business leaders
• Help balance speed and risk by providing clear, practical guidance to non-legal stakeholders
• Escalate more complex or non-standard issues appropriately

Templates & Process Improvement

• Use and help maintain standard templates, clause libraries, and negotiation guidelines
• Contribute to improving contract workflows and processes to support a high-volume sales environment
• Identify recurring issues and help drive consistency in how they’re handled
• Use of legal tech tools to streamline processing of agreements and deal close

Cross-Functional Collaboration

• Work with internal teams (Sales, RevOps, and Security/Privacy) to ensure contract terms align with our business and product
• Provide clear, concise guidance on common contract terms and when to involve Legal
• Support internal enablement efforts by helping stakeholders better understand standard terms and processes

What We’re Looking For

Required Qualifications

• J.D. (or equivalent) from an accredited law school; admitted to practice in at least one U.S. jurisdiction.
• 6-10 years of relevant experience at in-house, with a strong focus on commercial technology transactions.
• Direct experience with:
  • Negotiating SaaS or cloud-based software agreements (customer and, ideally, partner/channel deals).
  • Data protection/security issues in commercial contracts (e.g., DPAs, security exhibits, incident response, audit rights).
• Excellent contract drafting, negotiation, and communication skills, with the ability to give succinct, actionable advice to non-lawyers.
• Demonstrated ability to manage multiple deals and priorities in a fast-paced, high-growth environment.
• Demonstrated experience working with and advising senior sales leaders

Preferred Qualifications

• Experience in house legal within SaaS
• Experience supporting channel, MSP/MSSP, or distributor models.
• Familiarity with international contracting issues (e.g., cross-border data transfers, GDPR basics, export control).
• Comfort leveraging AI and legal tech tools to streamline drafting, review, and knowledge management.
• A plus to have prior cybersecurity experience.

Mindset & Working Style

• Business-minded and pragmatic: you balance risk mitigation with revenue enablement.
• Comfortable working independently but enjoy collaborating with Sales, Channel, Product, Finance, and Security.
• Strong ownership mentality; you like building and iterating on templates, processes, and playbooks—not just running them.
• Clear, calm communicator who can operate under time pressure and with incomplete information.

Why Join Horizon3 Legal

• Opportunity to join a high-impact legal team in a dynamic, fast-growing startup
• Work on front-line commercial and channel deals that directly drive revenue and strategic growth.
