Principal, Commercial Contracts (Quantum Computing) - 690 in London

We’re looking for a Principal, Commercial Contracts to join our commercial sales team and support complex, high-value deals in a deep-tech environment. Our products are technically sophisticated, delivery is often milestone-based, and contracts must reflect real engineering, delivery, and customer-readiness constraints. This role is based in London and reports to the Director of Business Management and is focused on commercial execution and deal enablement, not pure legal interpretation. You’ll work closely with Sales, Business Management, Finance, Technical, Product and Legal teams to structure, negotiate, and execute agreements that balance commercial goals with operational reality.

Key Responsibilities:

• Own the end-to-end commercial contracting process for customers and partners, from deal intake through execution, amendments, and renewals.
• Act as the primary commercial owner for contracts, supporting Sales and Business Management on live, complex deals.
• Draft, review, and negotiate commercial terms using approved templates and playbooks, including pricing structures, milestones, delivery obligations, SLAs, IP-related commercial terms, and renewals.
• Ensure contracts accurately reflect technical scope, delivery dependencies, and customer readiness, in collaboration with Product, Engineering, and Technical teams.
• Support bespoke, non-standard agreements common in deep tech, including multi-year, milestone-based, usage-based, or pilot-to-production deals.
• Partner closely with Legal to elevate non-standard legal risk, policy exceptions, or novel deal structures for review and approval.
• Coordinate with Finance on commercial terms, milestones, billing schedules, revenue timing, and contract changes.
• Develop and maintain contract data, documentation, and status tracking in contract lifecycle management and CRM systems.
• Create and scale contracting processes, templates, and playbooks to increase speed, consistency, and deal quality.
• Support renewals, amendments, change orders, and contract expansions as customers scale usage or move from pilots to production.
• Provide guidance to Sales and Commercial stakeholders on contracting timelines, risks, and best practices.

Must haves:

• 8+ years of experience in commercial contracts management, deal support, or commercial operations, in technology B2B or enterprise environments.

We value:

• Experience in deep-tech sectors such as quantum computing, AI/ML, semiconductors, advanced hardware, robotics, or scientific software.
• Familiarity with milestone-based delivery, R&D-heavy products, or early-stage customer deployments.
• Experience working with government, enterprise, or research-driven customers.
• Exposure to IP-sensitive commercial arrangements and collaborative development models.
• Experience improving contracting processes in scaling or pre-commercial organizations.
• Strong understanding of commercial contract structures and common enterprise contracting concepts.
• Experience supporting complex, high-value, and non-standard deals.
• Ability to balance commercial urgency with risk awareness and operational feasibility.
• Excellent attention to detail and strong organizational skills.
• Clear, confident communication with technical, commercial, and executive stakeholders.
• Experience using CLM tools and CRM systems.
