We are seeking a skilled and experienced Senior Frontend Infrastructure Engineer to join our Core Team.

- Work closely with product and R&D teams to understand requirements, influence technical decisions, and ensure infrastructure solutions align with real product needs.
- Serve as a senior technical authority in the frontend domain, leading by example through high-quality architecture, code, and best practices.
- Identify and implement improvements to the frontend development experience, including automation, developer tooling, code reuse, and performance optimizations.
- Take part in architectural discussions and help shape frontend standards and conventions across the organization.
- Stay up-to-date with modern frontend technologies, trends, and best practices, and apply them pragmatically to improve development efficiency and product quality.
- Conduct code reviews with a strong focus on maintainability, performance, and scalability.
- Troubleshoot and resolve complex frontend infrastructure issues in collaboration with other engineers and infrastructure teams.

- Strong understanding of software design principles and frontend architecture.
- Hands-on experience with frontend build tools and module bundlers (e.g., Webpack, Rspack, Vite).
- Strong software engineering fundamentals, including clean code, testing strategies, and design patterns.
- Proven ability to independently analyze complex technical challenges and deliver robust, scalable solutions.
- Strong communication and collaboration skills, with the ability to work effectively across teams.
Advantage
- Experience with backend technologies (e.g., Node.js, RESTful APIs) and cloud platforms (e.g., AWS, Azure).
- Experience building or evolving frontend infrastructure or design systems in a SaaS product at scale.
- Experience working closely with platform, infrastructure, or developer-experience teams.
- Strong background in frontend performance optimization.

We invite you to join our Core Team as a Senior Frontend Infrastructure Engineer, where you will have a meaningful impact on how frontend is built, scaled, and maintained across the company.
