You'll join as a Staff Frontend Engineer with a strong technical leadership role. Reporting directly to the Head of Engineering, you'll be responsible for shaping how Vendelux builds and evolves its customer-facing product. This is a full-time, hybrid role based in NYC (4 days in office expected). Key responsibilities include: - Own major product experiences end-to-end: technical design, frontend architecture, implementation, testing, measurement, and iteration. - Build and evolve the web application using TypeScript, React, Shadcn/MUI, and Node.js, with focus on usability, performance, reliability, and maintainability. - Set technical direction for frontend architecture, patterns, and engineering practices as the product scales. - Ship high-quality, secure, well-tested software through incremental, data-driven delivery. - Solve challenging product and technical problems across the stack, working with product, design, data, and backend engineers. - Partner with operations, revenue teams, and customers to understand product usage and turn feedback into better experiences. - Identify opportunities to improve frontend performance, developer experience, observability, testing, and application quality. - Work with leadership to define product roadmap and technical strategy. - Mentor engineers through pair programming, code reviews, architecture discussions, and hands-on technical leadership. - Contribute across the stack when appropriate, influencing APIs, data platforms, and infrastructure. Tech stack: Frontend (TypeScript, React, Shadcn/MUI, Node.js); Backend (Python, Django, TypeScript, Node.js, MySQL, Postgres, AWS, GCP); Data (Python, Dagster, Snowflake); Tools (Linear, GitHub, Datadog, Cursor/Claude Code). REQUIREMENTS: - 10+ years of experience building complex software applications, with significant experience building modern web applications. - Deep experience with TypeScript and React, with strong opinions about building maintainable, performant frontend systems. - Track record of shaping and shipping valuable product features. - Strong understanding of frontend architecture, state management, API integration, testing, accessibility, performance, and modern web development practices. - Experience with component libraries and/or design systems (Shadcn, MUI). - Comfortable working across the stack and understanding how frontend decisions interact with APIs, databases, data pipelines, and infrastructure. - Experience deploying production applications and services on AWS or GCP. - Good judgment around technical debt, architectural tradeoffs, and optimization priorities. - Comfortable using modern AI development tools to accelerate development. - Experience with infrastructure as code (IaC), preferably Pulumi. - Familiarity with network security and protecting production applications. - Strong written, verbal, and presentation skills for communicating technical decisions to engineers and non-engineers. - Drive to raise the engineering bar through patterns, tooling, documentation, and best practices. - Ability to build in the open, share context generously, and help other engineers become more effective. - Experience with data-intensive applications is a plus; familiarity with moving, ingesting, and transforming data at scale is valuable but not required.
