What will I be doing?

Lead the localisation efforts for our global energy billing platform, ensuring it meets the specific regulatory, market, and cultural requirements of France, from meter read to bill.
You'll be in charge of the French localisation of the Billing Module—one of the core product domains at the heart of the Kaluza platform. The Billing module processes consumption, pricing, and account data to schedule, calculate, and generate accurate, timely, and compliant invoices throughout a customer’s lifecycle. The module automatically manages billing cycles, generates bills, handles corrections, and produces the data that feeds invoices, billing-related communications, payment schedules, and downstream financial reporting, while powering customer and agent UIs.

This is a hands-on, full-stack product role — you'll work across the whole domain and alongside PMs from other domains and from the global billing teams to ensure the overall billing  journey from meter to bill meets the requirements of French clients.

• Collaborate intensely with clients and in-country experts to understand their unique needs and requirements, negotiate scope, and build a roadmap.
• Deep dive into French energy market regulations, translating complex compliance needs into detailed product specifications for the billing system.
• Define and manage detailed product requirements for features related to country-specific needs from getting a read to generating a bill (meter reading protocols, invoice formats, taxation rules, payment methods, and regulatory reporting).
• Work closely with engineering, UX, and QA teams to ensure the successful implementation and testing of localised billing functionalities.
• Act as the go-to expert for global teams on specific French market nuances related to energy billing and customer journeys.
• Continuously monitor changes in French energy legislation and market practices, proactively adapting the product roadmap to maintain compliance and competitiveness.

About You

Ideally you'll have/be:

• Proven experience as a Product Manager, or equivalent role in software companies, with a strong track record of successfully localising complex software products for international markets
• Solid understanding of the end-to-end B2C billing lifecycle including meter data, tariffs, invoicing, and debt management.
• A track record in regulated markets where billing complexity matters, energy, telecoms, financial services, or similar. Familiarity with the French energy market (ENGIE, CRE, switching, tariff structures) is advantageous.
• Exceptional ability to translate abstract regulatory text or client requirements into clear, actionable, outcome-driven requirements for development teams.
• Experience collaborating with cross-functional teams (engineering, design, legal, operations, client success) to deliver localised solutions.
• Excellent stakeholder and client management skills, able to lead conversations across requirements, scope, expectations, and roadmap alignment, and communicate technical & market complexity clearly to varied audiences.
• Proficiency in AI tools throughout all stages of the product lifecycle — from discovery and ideation to delivery and iteration.Fluent in French and English — our platform and many of our teams operate in English, so you move easily between both.
• A builder's mindset — you're autonomous, learn fast, and aren't afraid to go deep. You're comfortable interrogating a codebase with AI tools, reading an API schema or data model, and writing a SQL query to get the answer you need.
• Comfortable with ambiguity and pace — you can operate effectively when not everything is defined, know when to make a call, and aren't afraid to escalate or ask for help when it matters.
• Fluent in French and very comfortable in English — our platform and many of our teams operate in English, so you move easily between both
