Company Description

Flexcity is one of Europe’s leading energy tech companies and part of the Veolia Group. Operating in France, Belgium, Spain, Italy, UK and the Netherlands, we aggregate and optimize thousands of flexible energy assets (batteries, industrial processes, renewables...) to support grid stability and drive the energy transition.

At Flexcity, Tech is not a support function — it is a key business driver. We operate in a complex, real-time, and highly regulated environment, requiring robust, secure, and adaptable systems to manage the increasing volatility of energy markets.

We are looking for an Engineer Manager (H/F) for our Colombelles office. 

Job Description

As Engineering Manager, you’ll play a central role in shaping and scaling our engineering organization. You’ll ensure our teams are empowered, effective, and aligned — enabling the real-time control of hundreds of MWs across multiple markets.

Reporting directly to the CTO and working within a multi-country team, you’ll split your time across people leadership, collaboration with Product, organizational scalability, and engineering excellence.

People & Team Management - 50%

• Lead and coach two feature teams (around 10 people in total).

• Set clear goals, foster individual growth, and cultivate a positive, high-performance culture.

• Support career development and mentoring for your team members, in collaboration with our technical experts.

Product Collaboration - 30%

• Act as a duo with the Product Manager to align product vision and technical execution.

• Help to translate product vision into clear and pragmatic long-term technical initiatives.

• Balance delivery speed, technical debt, and long-term investments in partnership with the PM.

Organizational Scalability - 10%

• Contribute to the structuring and scaling of the engineering organization as it grows.

• Drive recruitment, onboarding, and the development of future technical and people leaders.

• Help design the organization, optimize collaboration across teams, and ensure alignment with company strategy.

Engineering excellence - 10%

• Promote best practices in software engineering (code quality, testing, CI/CD, observability).

• Encourage a culture of continuous improvement and knowledge sharing.

• Collaborate with other Engineering Managers and technical experts to streamline delivery and ensure consistency across teams.

Core requirements

• Background in software development, with good understanding of modern engineering practices.

• First experience in managing people (as team lead, engineering manager, or similar).

• Fluent in French (spoken and written) and comfortable in English at a professional level.

Leadership & Mindset

• Good communicator, able to explain ideas clearly to both technical and non-technical audiences.

• Focused on supporting people’s growth and creating a healthy team culture.

• Able to balance short-term delivery with longer-term structure and scalability.

• Pragmatic and improvement-oriented: looks for better ways of working without over-engineering.

• Works well across teams and functions, building strong collaboration.
