About Diametral

Diametral is built on 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.

Our approach combines strategy, data, technology, operating model, design, analytics, and long-term execution. We partner with some of the world's most ambitious organizations to move from experimentation to enterprise-wide AI adoption.

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.

Joining Diametral means joining a company at a defining moment: global ambition, entrepreneurial energy, and the opportunity to shape how organizations will operate for decades to come.

You will be a great fit at Diametral if you:

• Are energized by building something ambitious from the ground up
• Believe AI will become the new operating layer of modern organizations
• Seek impact, ownership, and continuous growth
• Enjoy working in international, multicultural environments
• Want to help shape the future of work, not simply adapt to it

Diametral is built on ambition, excellence, and execution. We value ownership, clarity, intellectual honesty, and long-term impact.

Context

We are a pure-play Data & AI consulting firm operating at the intersection of strategy, technology, and execution, with one clear ambition.

Design, build, and scale concrete AI systems delivering measurable business impact.

As Diametral continues to grow, the complexity of the organization grows as well: new offerings, new business units, new geographies, new strategic initiatives. The CEO is involved in all critical decisions across growth, operations, talent, organization, offerings, and expansion.

To continue scaling effectively, we are looking for a Chief of Staff Intern who will work directly alongside the CEO to help structure priorities, drive execution, and accelerate decision-making.

This is a high-exposure, high-responsibility role, designed for someone who wants to understand how a fast-growing company is built and operated from the inside. You will have direct visibility on strategic discussions, executive decisions, operational challenges, and company-building initiatives.

As Chief of Staff Intern, you act as a force multiplier for the CEO. Your role is simple: increase the organization's ability to execute. You will contribute to some of the most important projects within the company and help transform strategic decisions into measurable outcomes.
