Your role

As Head of Frontend | Web & Mobile at Ageras, you’ll lead frontend across our evolving SaaS universe. You’ll unify how we build web and mobile apps across the organization, manage a small but mighty frontend team, and collaborate with product, design, and engineering to define standards, advocate best practices, and consolidate our frontend stack into a modern, cohesive architecture. This role owns the frontend strategy for a multi-product SaaS company and aims to consolidate toward a single shared web frontend and a unified mobile app (or a modular foundation for them).

Responsibilities

• Define and evolve Ageras’ frontend architecture vision for web and mobile, focusing on shared codebases, reusability, and developer productivity.
• Consolidate acquired SaaS frontends into:
  • A single web frontend framework powered by a shared design system and components.
  • A unified mobile app architecture (or a shared mobile codebase), likely using Expo + React Native.
• Collaborate with leadership and marketing on whether separate customer-facing mobile apps are needed for branding, while ensuring a common technical foundation.
• Advocate for developer-friendly practices, tooling, and CI/CD workflows to reduce cognitive load and encourage contributions from full-stack developers.

Technical Oversight

• Own the frontend platform stack and tooling (storybook libraries, bundlers, test frameworks, CI/CD pipelines, monorepo) built on the foundations provided by the Engineer Efficiency team.
• Collaborate with product teams to gather feedback and guide building applications aligned with unified architecture and design standards.
• Ensure mobile development is accessible alongside web development by abstracting native complexities, using Expo, and automating testing and release processes.

Team & Collaboration

• Manage, mentor, and support a small team of frontend platform engineers.
• Partner with product engineering teams to enable adoption of shared components and standards.
• Drive knowledge sharing through chapter meetings, documentation, and hands-on support.
• Collaborate with the Architecture Forum to align frontend strategies with backend and platform evolution.
• Work with the design team to build and co-own a scalable Design System.

About you

• Hands-on experience with mobile frontend development, including React Native and mobile deployment pipelines.
• Proven experience leading frontend teams or projects, ideally in a SaaS or platform setting.
• Deep knowledge of React (web + native) and strong understanding of mobile development pipelines.
• Experience with Expo, EAS, React Native CLI, and mobile CI/CD pipelines.
• Passion for developer experience, tooling, documentation, and knowledge sharing.
• Strong communication skills and the ability to define standards and influence engineers across teams.
• Strategic thinking to balance long-term platform needs with delivery pressures.

Nice to have

• Experience managing multi-brand frontend architectures.
• Knowledge of monorepo tools (e.g., Turborepo, Nx) and design systems (e.g., Storybook, Figma integration).
• Previous exposure to merger or post-acquisition technical consolidation.

What success looks like

• Ageras frontend developers can contribute across web and mobile products.
• Mobile builds and updates are automated and painless with EAS, CI, and shared tooling.
• We operate with a shared component library across products, reducing duplication and increasing speed.
• Release cycles shrink and product teams focus on features rather than toolchains.
• We support a monorepo architecture with shared logic, UI, and bounded contexts (e.g., @ageras/app-invoice, @ageras/app-banking).
• Developers share a common vision for delivering great UI to Ageras customers.
• Designers are confident that what they build reflects the final production result.
