Description du poste

Requirements

• You have 7+ years of experience in software engineering with a strong focus on large-scale frontend architecture
,
• You have a proven track record of decoupling monolithic applications or building plugin architectures
,
• You are proficient in React and TypeScript, and you possess deep knowledge of bundlers (Vite preferred), the TanStack ecosystem (Router, Query), and monorepo tools (Turborepo, pnpm workspaces)
,
• You have experience with GraphQL architectures and can reason about API design at scale
,
• You have strong opinions (loosely held) on Micro-Frontends vs. Modular Monoliths and can articulate the trade-offs of each approach
,
• You stay current with modern development practices and tooling, including AI-assisted development tools, to maximize your productivity
,
• You are business-centric: You understand that technical architecture must serve business velocity and organizational scalability
,
• You have excellent communication skills and can rally different teams behind a shared technical vision
,
• You like sharing your ideas and you're open-minded. You can set a vision that others are excited to get behind

What the job involves

• We are looking for an engaged and passionate Senior Software Engineer to join our Workspace team with a focus on Frontend Architecture
,
• You will be responsible for evolving Aircall's frontend architecture into a true platform
,
• We already have a monorepo with ~40 packages and multiple applications, but as we grow, we need to enable parallel contributions from distinct feature teams without creating bottlenecks or architectural conflicts
,
• Your goal is to design the architecture that makes this collaboration seamless, safe, and performant
,
• You will act as an enabler for the entire engineering organization, setting the standards for how frontend code is written, shared, and deployed at Aircall
,
• Evolve our frontend architecture from a centralized monorepo to a true platform where distinct feature teams can contribute autonomously without blocking each other
,
• Evaluate and implement architectural patterns (Module Federation, advanced package isolation, plugin architectures) to solve our scaling challenges while maintaining the benefits of our existing monorepo structure
,
• Build the "paved road" for other teams. Create the tooling, contracts, and isolation layers that allow the feature teams to ship value without breaking the host application
,
• Establish clear boundaries and APIs between platform and features, ensuring changes to shared packages don't create cascading regressions
,
• Drive consistency across the frontend stack: standardize patterns for routing, data fetching, state management, and styling while allowing flexibility where needed
,
• Define and enforce coding standards, performance budgets, and architectural guidelines across the frontend guild
,
• Mentor engineers across the organization and align different stakeholders on technical vision
,
• Drive projects that increase the platform’s resilience and scalability
,
• Our Platform Foundation: You'll be building on top of a mature monorepo infrastructure:
,
• Turborepo + pnpm workspaces managing ~40 internal packages
,
• React 18 + TypeScript across all frontend applications
,
• Vite for builds (transitioning from legacy Webpack in some apps)
,
• TanStack ecosystem: Router for navigation, Query for server state
,
• GraphQL as primary API layer with REST fallback
,
• State management: Zustand (simple state), XState (complex flows)
,
• Styling: styled-components, Tailwind CSS and Shadcn in newer apps
,
• Design system: Tractor, our internal component library shared across apps
,
• Testing: Vitest + React Testing Library
,
• Modern developer experience with AI-assisted development (Cursor, Claude), fast CI/CD, type-safe workflows
