AI Powered Tech Lead - CDI Paris

Tech Lead

Theodo accompanies innovative companies since 2009 in the conception, development, and deployment of ingenious digital products - such as the TF1+ platform, the LCL Pro application, or the France Identity Digital application - by leveraging the best of technology and the Lean approach.

Theodo has experienced exceptional growth over the last 15 years: our teams bring together more than 700 Theodoers, mainly software engineers, passionate about technology and continuous improvement. In 2025, Theodo Group generates 100M€ of revenue.

Your team:
You will join a tech community of more than 350 Theodoers: software engineers, tech leads, engineering managers, and architects, with whom you can exchange, learn, and progress on a daily basis. At Theodo, techs work in project teams, formed according to the needs of each client. You will be part of a team of Theodoers of human size (4 to 5 people), bringing together software engineers, tech lead, and product manager.

Together, you will collaborate closely with the client, with regular exchanges to share your progress, deepen the understanding of its problem, and evolve the product as close as possible to the needs of its users. The software engineering professions evolve with AI: come learn to become an AI native tech lead.

Your future missions:
We are recruiting a Tech Lead to design and develop useful, high-performing, and sustainable digital products to meet the challenges of our clients and their users. As a Tech Lead, you are responsible for the delivery and quality of your project. You mobilize your team, make the technical choices adapted to the context, and support the software engineers in their progress, with the objective of growing both the product and the people who build it.

Guarantee the delivery and quality of the project

You aim for a radically superior level of quality, by structuring the delivery around standards:

• Design scalable and resilient architectures (clear and shared architecture diagrams)
• Write precise specifications to enable bug-free development of functionalities
• Implement a quality strategy based on: clean code, automated tests, code reviews
• Ensure a structured work environment with the 5S principles (organization, clarity, efficiency)
• Accelerate the speed of development through the deployment of AI agents

Be the technical partner of the client

• Participate in project routines (backlog refinement, daily, ceremonies) and ensure continuous client satisfaction
• Explain and defend the technical choices to create trust and align all stakeholders

Create the performance conditions of the team

• Implement an effective and structured work environment for the project team
• Implement loops for solving problems through daily problem solving
• Create conditions for the team to exploit LLMs and gain productivity in their daily lives

Advance the software engineers of your team

• Analyze in-depth the defects at the source in order to improve the knowledge of the teams (Dantotsu)
• Train and support the team (pair programming, code reviews, training)

The challenges are very different from one project to another, here are some examples:

• Health Hero:
  We helped Health Hero scale a critical telemedicine platform at the European scale, with a strong focus on quality and reliability. Result: a robust product that can handle the load and support millions of users without compromise on experience.
• LCL:
  Development of the new neobank of LCL (L by LCL), a digital platform allowing professionals to open and manage their bank account online.

Your perspectives for evolution:
Two axes of evolution are available to you:

• Senior Architect: develop technical expertise
• Solution Architect: participate in the sale of complex projects by defining the most ingenious technical solutions to allow us to win
• Managerial:
  Engineering Manager

A methodology based on continuous learning:

At Theodo, we have built our tech approach around a strong conviction: we develop people first, before developing products. Our Lean Tech® System emphasizes continuous learning: you will evolve in an environment that invests in the long term, where the objective is to allow you to progress every day, while building…
