At Q-tech, we are collaborating with a technology company specializing in energy management that is experiencing strong growth and is in the midst of a transition to create a market-leading platform.

It manages millions of data points to generate energy consumption savings for companies, providing a solution ranging from Hardware to software and the execution of those savings.

With a turnover of more than 5 million euros, it has raised several funding rounds and is currently in a process of both organic and inorganic growth.

The company aims to lead the corporate energy management market in Spain by 2030, and to achieve this, it already manages thousands of clients of all types.

Additionally, it is executing an integration and development plan based on the integration of innovative Artificial Intelligence projects.

The person occupying this role will be responsible for defining the target architecture and leading the company's technical evolution at a key moment.

The role requires solid technical judgment, the ability to make clear decisions, the capacity to work with teams using different stacks, and the ability to align technology and business with focus and consistency.

We are looking for someone who leads from practice, who can dive into detail when necessary, and who understands how AI and new working models can accelerate development.

They will be responsible for coordinating engineering teams, establishing common standards, and ensuring that the resulting platform is robust, scalable, and prepared to grow, while maintaining a healthy and collaborative working environment. They will work directly with the CEO to prioritize, plan, and execute a demanding roadmap, with a direct impact on product and strategy.

· Define the target architecture of the unified platform, considering the two current products and real business needs.

· Deeply analyze existing systems (Java/Angular and .NET) to decide which components are maintained, refactored, or redesigned from scratch.

· Design services and modules with a focus on robustness, scalability, maintainability, and observability, avoiding unnecessary complexity.

· Integrate applied AI capabilities (proprietary and generative models) within the functional and technical design of the product.

· Consolidate a solid engineering environment: stable pipelines, automated testing, monitoring, and practices that allow working with reliability and rhythm.

· Act as the technical reference for the team: validate architectural decisions, review designs, and resolve complex problems.

· Participate directly in the implementation of key components, especially during the initial phases of the redesign.

· Ensure code quality, technical consistency between teams, and a technological foundation that allows for growth without friction.

· Align development work with the AI team so that models become a natural part of the product.

· Work directly with the CEO to define the roadmap, priorities, and strategic decisions.

· Translate business needs into concrete technical decisions, balancing vision, cost, complexity, and time.

· Participate in key technological integration decisions following the merger.

· Identify technical risks and propose realistic solutions, anticipating problems and avoiding compromising the future evolution of the product.

Salary range: €60-80K gross/year, depending on experience and fit.
