The Opportunity

We’re seeking a Corporate Counsel to join Arize AI as our first in-house legal hire. Reporting to leadership and working closely with our outside General Counsel, you’ll own the day-to-day legal operations that fuel our business growth. This is a high-impact role where you’ll negotiate critical customer and vendor agreements, ensure commercial transactions move efficiently, and build the legal foundations for a scaling organization.

This role is ideal for a commercially-minded attorney who thrives in a fast-paced start-up environment, enjoys being hands-on, and wants to shape legal processes from the ground up.

What You’ll Do:

• Contract Negotiation & Management: Lead negotiations and draft customer agreements, vendor contracts, partnership agreements, NDAs, and other commercial contracts that drive revenue and support operations
• Revenue Enablement: Partner closely with Sales, Customer Success, and Revenue teams to accelerate deal cycles while managing legal risk appropriately
• Vendor & Procurement: Review and negotiate SaaS agreements, professional services contracts, and other vendor relationships to support company operations
• Policy & Process Development: Build scalable contract templates, playbooks, and processes to enable the business to move quickly as we grow
• Cross-functional Collaboration: Serve as a trusted legal advisor to Sales, Product & Engineering, Marketing, HR, and Finance on a wide range of business matters
• Outside Counsel Coordination: Work effectively with our external General Counsel on corporate governance, equity administration, employment matters, IP, and strategic legal issues
• Compliance & Risk Management: Identify legal and compliance risks, develop mitigation strategies, and ensure adherence to relevant regulations (data privacy, security, etc.)
• Special Projects: Support fundraising, due diligence, and other strategic initiatives as the company scales

What We’re Looking For:

Required:

• JD from an accredited law school and active bar membership in good standing
• 3-5 years of legal experience, with significant focus on commercial contracts (preferably in SAAS, technology, or start-up environments)
• Strong contract drafting and negotiation skills with a business-oriented mindset
• Ability to work autonomously, prioritize effectively, and manage multiple workstreams simultaneously
• Excellent judgment in balancing legal risk with business objectives
• Clear, concise communication skills and ability to explain complex legal concepts to non-legal stakeholders
• Start-up mentality: scrappy, adaptable, and comfortable with ambiguity

Preferred:

• In-house experience at a high-growth SAAS or technology company
• Familiarity with AI/ML, data privacy regulations (GDPR, CCPA), and enterprise software licensing models
• Experience supporting sales and revenue organizations
• Knowledge of corporate governance and securities law
