Frontend Engineer

Context & Vision

In 2026, writing code is no longer the primary bottleneck; managing its complexity and ensuring its reliability is. We are building a highly resilient advertising platform with a very lean, senior internal team, and we intend to keep it that way.

To achieve scale without the overhead of a large engineering department, we rely on an AI-first development paradigm and a philosophy borrowed from the best large-scale open-source projects. Our code is not public, but our governance is theirs: asynchronous communication, exhaustive written documentation, explicit rules, and uncompromising quality gates. It is the only way a small team of humans and AI agents ships serious systems without accumulating technical debt.

This role owns the entire product surface: the console through which advertisers and agencies run their campaigns.

The Role

You will own the frontend of the platform end to end - the advertiser and agency console where campaigns, audiences, creatives and reports come to life. This is the most visible part of the build and, today, the least finished; you will have real ownership and a large surface to shape.

• The Advertiser & Agency Console.** Build and own the product UI: campaign and line-item management, inventory, creative assets, reporting dashboards, account and admin modules, and the conversational agent interface. You are responsible for how the product feels to use.
• A Typed, Contract-First Client.** Our frontend consumes the backend through a typed, contract-first client. You keep the contract tight: no drift between what the backend promises and what the UI assumes.
• A Real Design System.** The product is standardising on a proper design system. You will own its implementation, keep components consistent, accessible and internationalised (FR / EN / AR), and work with the studio on the visual direction rather than reinventing it per screen.
• AI-First Delivery & Governance.** We expect AI to write most of the code; you are the editor, not the typist…
