The Senior Frontend Platform Engineer role focus on building the systems, tools, and pipelines that enable engineers to deliver high-quality software more efficiently and reliably. This is not a product feature development role. Instead, Frontend Platform Engineer will work at the intersection of tooling, infrastructure, and developer experience to improve the effectiveness and velocity of engineering teams working in a large-scale monorepo environment. Creating cleaner, faster, and more resilient workflows, robust automation and reliable pipelines are essential to productive software development.

What You'll Do:

Developer Experience & Tooling

• Identify friction points in frontend workflows and design automation solutions to remove them.
• Own and evolve tooling across our client monorepo using technologies like Vite and Nx.
• Provide technical support and guidance to engineers to help them use internal tools effectively.

CI/CD Pipeline Optimization

• Design and optimize frontend-specific CI/CD workflows for speed, reliability, and scalability.
• Extend CI/CD pipelines with capabilities such as preview app deployments, Lighthouse CI, Storybook and static asset analysis.
• Collaborate with platform teams to build standardized, scalable pipeline templates and integrations.

Cross-functional Enablement

• Partner with product engineering teams to identify friction points in build, test, and deployment processes.
• Promote adoption of best practices through internal education, technical guidance, and documentation.
• Act as an advocate for continuous improvement and operational excellence in frontend development.

What You'll Bring:

• Strong proficiency in JavaScript and TypeScript, with hands-on experience in modern frontend frameworks (e.g., React, Vue, Angular).
• Deep understanding of frontend build systems and tools (e.g., Vite, Webpack, Rollup, Nx).
• Practical knowledge of CI/CD systems (e.g., GitHub Actions, GitLab CI, Jenkins), with a track record of building or maintaining pipelines.
• Background as a frontend engineer with a focus on developer productivity, tooling, or infrastructure.
• Excellent debugging and communication skills, with a collaborative approach to problem-solving.
• Experience working in and maintaining large-scale frontend monorepos, preferred.
• Experience with containerization (Docker, Kubernetes) and cloud infrastructure (AWS, GCP), preferred.
• Familiarity with developer experience metrics and a methodical approach to continuous improvement, preferred.
• Experience building and maintaining internal developer tools used at scale, preferred. #LI-HYBRID
