Diametral in Paris seeks a Business Manager at the start of their career to own a small perimeter: open accounts, recruit consultants, and deliver results from day one. You will drive Data, AI, and technology transformation initiatives, build proposals, and secure opportunities.
You will craft a scalable client portfolio, ensure delivery quality, and foster long-term relationships while developing leadership capabilities. This role offers real ownership and a fast growth path.
Diametral is built on a core conviction: AI is not another technology wave. It is a structural shift in how companies operate, compete, and create value.
Our mission is to help organizations become AI-native. We redesign critical business processes, embed intelligence at the core of operations, and build systems where humans and AI work together at scale. The result is tangible: faster execution, stronger performance, sustainable growth, and durable competitive advantage.
We are not a traditional consulting firm, nor a conventional technology services company. Diametral exists to solve a challenge these models were not designed for: the end-to-end transformation of enterprises for the AI era.
Founded from the success of LittleBigCode, established in 2018, Diametral was created in 2026 with a clear ambition: become the global reference for AI-native business transformation. Today, we operate across Europe and the Americas, supporting multinational organizations with a scalable delivery model focused on measurable business outcomes, ROI, and operational excellence.
Growth is not an abstraction at Diametral. It is built account by account, consultant by consultant, mission by mission.
The Business Manager owns a perimeter: a portfolio of clients, a team of consultants, and the performance of both. We are looking for a Business Manager at the start of their career who wants to build that perimeter from the ground up rather than inherit one.
This is not a support role, and it is not a sales role in the narrow sense. You are accountable for a small profit center from day one: you open accounts, you recruit the consultants who will deliver on them, you make sure the work lands, and you own the numbers. You will be trained, coached, and challenged — and you will be given real responsibility far earlier than you would elsewhere.
Open and grow your client portfolio on Data, AI, and technology transformation topics.
Impact. Diametral's client base expands with accounts that have real strategic substance.
Build the team that delivers on your perimeter.
Impact. Growth is never limited by the quality of the people available to deliver it.
Put the right consultant on the right mission, and keep them growing.
Impact. Consultants progress, clients get the right expertise, and utilization stays under control.
Own the economics of your perimeter.
Impact. Your perimeter grows profitably, with numbers you can explain and decisions you can justify.
Turn a first mission into a durable partnership.
Impact. Clients come back, and each account becomes a platform rather than a transaction.
Contribute to how the commercial engine itself is built.
Impact. The organization gets stronger as it grows, not heavier.
Joining Diametral means joining a company in active construction mode, at a defining moment: global ambition, entrepreneurial energy, and the opportunity to shape how organizations will operate for decades to come.
Business Leaders, Engine Directors, Data and AI experts, the Talent team, and the Executive Leadership Team.
Contract: permanent (CDI). Location: Paris.
Diametral is built on ambition, excellence, and execution. We value ownership, clarity, transparency, intellectual honesty, and long-term impact.
We are looking for builders. Not observers.
