Location: Paris, France (hybrid, three days a week in the office; occasional travel to Brussels and London)
Level: Programme Manager senior
Team: Client Delivery
Contract: Permanent
Reporting To: Operating Model Design Lead

Please note: This role is based in France, so you need to live here or be open to relocating, and it requires an existing right to work in the EU. We can’t offer visa sponsorship, but we review sponsorship role by role, so keep an eye on our careers site for future opportunities.

Fluent French and English (spoken and written) are essential, and we kindly ask you to submit your CV in English.

About Kaluza

Kaluza is the Energy Intelligence Platform, turning energy complexity into seamless coordination. We help energy companies overcome today’s challenges while accelerating the shift to a clean, electrified future.

Our platform orchestrates millions of real-time decisions across homes, devices, markets and grids. By combining predictive algorithms with human-centred design, Kaluza makes clean energy dependable, affordable and adaptive to everyday life.

With teams across Europe, Asia and Australia, and a joint venture with Mitsubishi Corporation in Japan, we power leading companies including OVO, AGL and ENGIE, as well as innovators like Volvo and Volkswagen.

What you’ll do

• Own change and transformation support for go-live readiness for ENGIE France’s migration onto Kaluza as the hands-on lead, from planning through cutover, hypercare and transition towards scaling, so ENGIE’s teams are ready and confident to adopt the platform from day one.

• Decide the change approach for the programme: stakeholder analysis, change impact assessment, training design and business readiness engagement, shaped to ENGIE France’s operating context and owned by their teams.

• Operate Kaluza’s business readiness governance: stage gates, readiness evidence, risk and dependency tracking and weekly reporting.

• Partner with the Learning and Adoption Specialist in France to coordinate training, Train the Trainer and knowledge content, so enablement lands throughout each programme increment as we build out and release features via Agile delivery.

• Be the day-to-day point of contact for ENGIE France on business readiness, change and adoption, giving practical change advice to their transformation leads.

• Track adoption and operational stability through hypercare, root-cause any shortfall against acceptance criteria, and agree interventions with ENGIE.

• Improve Kaluza’s readiness playbook: evolve what worked on ENGIE Belgium, test fixes where it falls short in France, and share what you learn with colleagues across Client Delivery to shape the platform’s operational foundations and improvements and to set our global standards.

Day to day, the activities you’ll lead or support include:

• Change impact and readiness planning: diagnosing the full scope of impacts across roles, workflows, systems and customer experience, then turning them into a prioritised readiness plan sequenced against delivery, migration and release cadence.

• Stakeholders, sponsors and change networks: mapping stakeholders and influence at workstream level, helping sponsors stay visible and engaged, and shaping the champion, superuser and people-manager networks that carry change into ENGIE’s business.

• Communications and resistance: supporting ENGIE France’s own communications and engagement strategy, so their teams and customers hear a consistent, positive story about the programme. You’ll help leaders and champions advocate for the change, internally and with customers, and anticipate where resistance may form so you can intervene before it becomes entrenched.

• Migration and go-live readiness: building the business and operational readiness evidence that enables a smooth transfer to service, measured against the agreed acceptance criteria, and supporting the go-live command centre.

• Hypercare and stabilisation: agreeing hypercare entry and exit criteria, monitoring stability and adoption signals, and handing over cleanly to ENGIE’s business-as-usual teams.

• Early releases and workarounds: planning for known limitations in early releases, and reflecting them in training, knowledge and communications so users are never caught by surprise. You’ll work with Release Management so each platform release arrives with the enablement it needs.

What you’ll bring

Ideally, you’ll have:

• Several years of hands-on change delivery on large platform or systems transformations, with a recognised change management discipline. You solve a wide range of problems creatively and work with little supervision.

• Experience in regulated, customer-facing operational environments, including live customer account migration, cutover and go-live, where you have shaped the approach rather than only followed one.

• Strong communication and stakeholder management, credible with client programme leads and transformation sponsors.

• Fluency in French and English, written and spoken.

• Comfort working with data: you explore adoption and programme data yourself, report on it clearly and challenge decisions when evidence is weak.

• Commercial awareness: you understand how Kaluza makes money and balance what the client needs against cost, working alongside SI partners and the client’s own change resources without duplicating effort.

What will set you apart: a background in energy retail or utilities, vendor-side experience on a SaaS implementation, and/or knowledge of contact centre operations and technology.

Our Values

• Play to win: Collective pride in decarbonising energy at scale.

• Solve the real problem: Cutting through complexity to focus on real-world outcomes.

• Build trust every day: Consistency, transparency and doing what we say.

• Own the outcome: Full accountability, wins and setbacks, without ego.

• Go further together: Collaboration, respect and different perspectives.

Our Perks

• Financial & Insurance: Discretionary bonus, Alan Mutuelle Health Insurance, x3 Life & Death insurance (Prévoyance) via Alan, and standard Sécurité Sociale contributions (pension, family allowance, unemployment insurance)

• Allowances: 50% commuting expense reimbursement, €200 Home Working Allowance, and €150 Learning Fund

• Time Off & Flexibility: 25 days holiday + bank holidays + RTT days, Moments That Matter Leave, Compassionate Leave, two paid Volunteering Days, Flexible Working, and Career Break eligibility
