Mosaic Conseil is a boutique consultancy that operates as a remote workshop. We do not produce slide decks or participate in the typical theater of corporate consulting. Our focus is on the reconstruction of business artifacts: financial models, pricing structures, and strategic plans.

We take these apart and rebuild them based on the evidence found in the ledger. Our work is precise and personal, involving a rigorous process where every document is built by one person and challenged by another. This ensures that every assumption is tested before a file is considered finished.

Currently, a major Spanish financial services group is central to our project list, and we are looking for a Project Management Assistant to help coordinate the flow of these rebuilds.

About Mosaic Conseil We are a small, independent firm that works entirely remotely. Our size is intentional. It allows us to maintain a high standard of quality where the people who perform the analysis are the same people who answer the telephone when a client has a question.

We specialize in four areas: financial services, industrial networks, software companies, and healthcare systems. Our approach is defined by written arguments and deep analytical work rather than meetings and presentations. Because we do not work on standing retainers, each project is a distinct engagement with a clear beginning and end. We provide a ninety day period of direct telephone support for every artifact we return, ensuring our work stands up to practical use.

What you would do As a Project Management Assistant, you will support the operational side of our rebuilding process. You will help manage the schedule for our engagement with the Spanish financial services group, ensuring that artifacts move through the builder and challenger phases on time.

Your daily tasks will include organizing the evidence folders, tracking the status of various financial models,



and maintaining the logs for our ninety day telephone support windows. You will be responsible for keeping the internal documentation clear and updated so that the builders and challengers can focus on their analysis. This role involves significant writing, as you will help format and organize the written arguments that accompany our rebuilt files.

You will also help manage the communication schedule, making sure that calls are only booked when they are strictly necessary for the project to move forward.

Helpful background This is an entry level role designed for someone who is organized, observant, and intellectually curious. You do not need a decade of experience, but you should have a basic understanding of business structures and a comfort level with financial documents.

If you have studied finance, economics, or business administration, that will be helpful for understanding the artifacts we handle. We look for individuals who can follow a complex argument and spot inconsistencies in a spreadsheet or a written report. Technical comfort with spreadsheet software is important, as is the ability to write clearly and concisely without using filler words.

Because we work remotely, you should be someone who can manage your own time and stay focused on detailed tasks without constant oversight. A background in academic research or technical writing can be an excellent foundation for this position.

How we work Our workshop is built on the principle of deep work. We do not have unscheduled meetings,



and we do not use internal messaging for things that should be handled in a thoughtful email or a shared document.

Every project at Mosaic Conseil follows the builder and challenger model. This means that for every financial model or plan we produce for the Spanish banking group, one person builds it from the ground up and another person is assigned to find the flaws in it. As the assistant, you will see this process firsthand and help facilitate the handoffs between these two roles.

We prioritize the evidence of the invoice ledger over corporate intuition. Our remote structure allows us to remain independent and focused on the facts at the floor of the business, away from the distractions of a traditional office environment.

What the role offers This position provides a rare opportunity to see the inner workings of high-level financial analysis and business reconstruction. You will work in a professional environment that values your time and your ability to focus on substantive tasks. Because we are a remote firm, you will have the autonomy to structure your workday in a way that promotes productivity.

We offer a permanent, full-time contract with a focus on long-term growth within our small team. The position is paid, and the compensation is competitive for the entry-level market, reflecting the high standard of work we expect. You will be mentored by experienced professionals who value intellectual honesty and precise thinking.

There is no corporate theater here: just meaningful work and a commitment to getting the details right for our clients.

Working at Mosaic Conseil means being part of a team that respects the discipline of the craft. We take pride in the fact that our work is backed by a written argument and a person who answers the phone. If you value clarity, evidence, and the quiet of a focused remote workshop, you will find this environment rewarding.
