Junior Interface Developer

Mosaic Conseil operates as a small, remote workshop dedicated to rebuilding one business artifact at a time. Whether it is a three-year plan, a pricing grid, or a diligence file, we take things apart on the bench and put them back together against the evidence of the invoice ledger. Our process is personal and focused. Every file carries two names on the cover: one person who builds and one who argues against what was built. This ensures that every assumption is tested before a file closes. We keep the workshop small on purpose to ensure that the people who do the work also answer their own phones. There are no meetings we did not schedule, and we focus on deep, intellectual work rather than corporate theater.
Our client is a major infrastructure and technology firm that requires high levels of precision in how their data and business logic are presented. As we assist them in rebuilding their internal models and reporting artifacts, we need a Junior Interface Developer to help translate these complex structures into functional, digital layers. This role is fully remote, allowing you to focus on the craft of development from your own environment while contributing to a small, disciplined team.

About Mosaic Conseil
We are a boutique consultancy that operates differently from traditional firms. We do not work on standing retainers and we do not produce slide decks. Instead, we return the same artifact a client sent us, redrawn by hand and supported by a written argument. Our work is handled on paper and backed by a telephone number that answers for ninety days. We focus on four specific rooms: financial services, industrial networks, growing software companies, and healthcare systems. By staying small and remote, we remain independent and focused on the evidence at the floor of the business. This environment is built for thinkers who value intellectual honesty and the discipline of deep work.

What you would do
In this role, your primary task is to support the creation and refinement of digital interfaces for the business artifacts we rebuild. You will work closely with the analysts who deconstruct the business logic, turning their findings into clear and usable front-end components. This is not about aesthetic flair: it is about clarity, accuracy, and logic. You will be building tools that help our infrastructure and technology client view their data with fresh eyes. This involves auditing existing interfaces for logical errors, building new layouts for financial models, and ensuring that every digital interaction serves the underlying written argument. You will also participate in our builder and challenger process, where you will present your code for rigorous internal review to ensure it meets our standards for evidence-based work.

Helpful background
We are looking for an individual at the entry level who is curious about the intersection of code and business logic. The following traits and skills will help you succeed in this remote role:

• Basic familiarity with HTML, CSS, and JavaScript, specifically in how they are used to display data.
• A clear, direct writing style that allows you to explain technical decisions without using jargon.
• The ability to follow complex logical arguments and translate them into functional interface elements.
• Experience with personal projects, university assignments, or internships that required solving specific technical problems.
• An interest in how large organizations, particularly in infrastructure and technology, manage their internal records.
• Comfort working independently and managing your own schedule without constant supervision.
• A willingness to have your work challenged and refined by colleagues as part of our quality control process.

How we work
Our workshop is fully remote and organized around the principle of deep work. We believe that the best work happens when people have the space to think and the time to build without the distraction of unnecessary meetings. We use a builder and challenger model for everything we produce. One person builds a model or an interface, and another person acts as the challenger, looking for weaknesses in the logic or the evidence. This process requires a thick skin and a commitment to the truth of the file. We communicate primarily through written arguments and scheduled phone calls, ensuring that every interaction has a clear purpose and a documented outcome.

What the role offers
This is a permanent, full-time position that offers a high degree of autonomy. The pay is competitive for the entry level market and reflects the high standard of precision we maintain. Working at Mosaic Conseil provides an opportunity to see the inner workings of major industries while sharpening your technical skills in a focused, distraction-free environment. You will be treated as a professional from the start, with the expectation that you will take ownership of your tasks and contribute to the collective argument of the workshop. We provide a space where your work is judged by its accuracy and its ability to withstand scrutiny.
We remain a small team by choice. This ensures that every member of the workshop is directly involved in the artifacts we return to our clients. Our focus on four specific sectors allows us to build deep expertise and provide evidence that actually matters to the ledger. We look for those who prefer the quiet discipline of the bench over the noise of a typical corporate office.
