What will I be doing?

As a key member of the Legal team, you will act as a strategic partner to the business, balancing commercial velocity with robust risk management. You will take ownership of complex, high-value deals that drive Kaluza’s global expansion, operating as the lead legal representative in commercial contracting processes with the confidence and authority that demands.

• Structure Strategic Deals: You will draft, negotiate, and close complex SaaS subscription agreements for the Kaluza platform, professional services contracts, and strategic partnership agreements with international enterprise clients. You will take clear positions on risk allocation and high-stakes issues involving IP licensing, cloud liability, service levels and data protection.
• Lead Negotiations: You will represent Kaluza as the lead legal negotiator in commercial discussions. This involves asserting Kaluza's position, maintaining critical commercial terms, and driving negotiations towards a successful outcome, collaborating effectively with the business team throughout the process.
• Drive Commercial Strategy: Acting as a core legal advisor to the Commercial and Bid teams, you will support RFPs, pricing structures, and risk allocation strategies for large-scale international deals, ensuring commercial viability while protecting the business. You will be solutions-oriented, adept at identifying pragmatic paths forward.
• Communicate with Precision and Impact: You will deliver concise, structured legal advice in fast-moving commercial conversations, distilling complexity into clear, actionable positions — not lengthy, discursive commentary.
• Scale Commercial Operations: You will partner with the Commercial team in evolving our commercial playbooks, to create a frictionless contracting process that ensures consistency and efficiency across the sales cycle.
• Empower the Business: You will design and deliver practical training to Revenue and Bid teams on contracting rules of engagement, deal hygiene, and regulatory risk, empowering them to move faster with confidence.
• Expert legal advice: You will provide pragmatic, business-focused advice on the legal matters directly impacting our SaaS platform, including data protection and privacy, InfoSec regulations, use of OSS and AI and cloud hosting.
• International Engagement: You will operate as part of a global deal team, occasionally travelling internationally to support high-value strategic negotiations in person.

About You 

You will be able to demonstrate all of the following:

• Qualified Solicitor: You are a qualified solicitor in England and Wales.
• Deep SaaS Experience: You bring a minimum of 8 years' PQE, gained in commercial/TMT departments of leading law firms and in-house roles within high-growth enterprise SaaS  companies.
• Tech Sector Expertise: You have a mastery of commercial contracts specific to enterprise software implementation and delivery, with deep knowledge of IP licensing, cloud hosting nuances, and liability caps in a SaaS context.
• Proven Negotiation Authority: You have a demonstrable track record of leading commercial negotiations end-to-end as the sole or lead legal representative. You take clear, defensible positions on liability, risk, and commercial terms in live negotiations and do not require frequent validation from senior management.
• Decisive and Autonomous: You take ownership of decisions and provide your position on a legal or commercial issue with clarity and conviction. You are trusted to operate independently and represent the business without close oversight.
• Concise and Precise Communicator: You communicate with clarity and economy, distilling complex matters into clear actional guidance, and avoid making assumptions
• Global Mindset: You have a proven track record of drafting and negotiating contracts that bridge multiple international jurisdictions (e.g., EMEA, North America, APAC).
• Commercial Acumen: You don't just quote the law; you translate complex legal issues into clear, actionable business advice. You understand the balance between protecting the company and getting the deal done.

What will set you apart 

• Scale-Up DNA: Previous experience working in a high-growth SaaS or technology scale-up environment, where you have thrived in ambiguity and rapid change.
• Energy Sector Knowledge: We are looking for candidates who are engaged with our mission and can articulate why the energy sector matters to them.
• Privacy Specialist: Experience handling advanced data privacy matters beyond basic GDPR compliance, particularly in relation to cloud data and cross-border transfers.
