Mosaic Conseil is a remote workshop dedicated to rebuilding business artifacts with absolute precision. We do not produce slide decks or participate in the typical cycle of corporate meetings. Instead, we take existing plans, pricing grids, and financial models, take them apart on the bench, and put them back together based on the hard evidence of the ledger. Our partner is a major Spanish infrastructure firm, and this engagement requires a high level of technical focus to ensure that their digital assets and data models are as sturdy as their physical networks. We remain small by choice, ensuring that the people who do the work are the same people who handle the results.

About Mosaic Conseil
We operate as a boutique consultancy where the work is personal and focused. Every file we close carries two names: one person who built the model and one who argued against it. This builder and challenger dynamic is at the heart of our culture, ensuring that no assumption goes untested. Because we are a fully remote team,



we prioritize written arguments and deep work over the distractions of a traditional office. We focus on four specific areas: financial services, healthcare systems, growing software companies, and industrial networks. Our commitment to independence means we stay away from standing retainers and focus entirely on the evidence found at the floor of a business.

What you would do
In the role of Web Developer Intern, you will focus on the digital side of our artifact reconstruction. You will assist in building and maintaining internal tools that help us audit complex financial data for our partner, a major Spanish infrastructure firm. This involves creating clean, functional web interfaces that allow our team to visualize ledger entries and network data effectively. You will not be building marketing sites, but rather functional, data-driven applications that support our written arguments. You will also participate in our peer review process, serving as either
