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.
Key Responsibilities :
- 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
Qualifications :
- 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.
