About Ethyca

Ethyca is redefining trust in the age of AI. We build automated data privacy infrastructure that embeds governance directly into data, ensuring policy, consent, and control live wherever data moves. Our clients include The New York Times and the world's most advanced organizations scaling AI responsibly. We're on a mission to make trust, respect, and privacy a default feature of every tech stack.

The Role

As a Senior II Frontend Engineer at Ethyca, you will be a technical leader and force multiplier on the engineering team. You'll architect and build sophisticated user interfaces that power Fides enabling enterprises to manage data governance, consent, and privacy rights at massive scale. This role demands deep technical expertise, design sensibility, and the ability to mentor others while shipping high-impact features that directly affect how the world's largest organizations deploy AI responsibly.

Core Responsibilities

1. Technical Leadership & Architecture

• Lead the design and implementation of major frontend components and systems, from complex data visualization dashboards to intuitive consent management interfaces to high-performance data grids
• Make critical decisions about component architecture, state management, and technology choices that will scale to support Fortune 500 customers managing billions of privacy requests
• Identify architectural risks and performance bottlenecks before they become issues; propose solutions that keep us ahead of customer needs
• Champion best practices in code quality, testing, accessibility, and documentation; raise the bar for the entire team

2. Build & Ship High-Impact Features

• Write clean, maintainable, well-tested code that serves millions of users and meets enterprise-grade reliability and performance standards
• Take projects from concept through design, implementation, testing, deployment, and iteration; driving outcomes, not just completing tasks
• Balance speed and excellence; ship rapidly while maintaining high standards for code quality, design polish, and user experience
• Leverage AI-assisted tools to accelerate development, improve code quality, and enhance productivity across the development lifecycle

3. Collaboration & Mentorship

• Provide technical guidance, code reviews, and architectural mentorship to help other engineers level up their skills
• Lead project planning sessions, write detailed technical specifications, and ensure alignment across engineering, product, and design
• Support the open source community through thoughtful PR reviews, issue triage, and helping users troubleshoot complex problems
• Work closely with Product, Design, and Customer Success to ensure technical solutions align with business goals and customer needs

4. Operational Excellence

• Design interfaces and components that handle enterprise workloads with demanding performance requirements, browser compatibility, and accessibility standards
• Use metrics, monitoring, and analytics to inform architectural choices and user experience improvements
• Take ownership of production systems; respond to incidents quickly and drive post-mortems that prevent future issues
• Identify inefficiencies in development workflows, tooling, and processes; propose and implement solutions

What We Require

1. Technical Expertise

• 8+ years building production-grade web applications with modern frontend frameworks, with proven track record of delivering complex technical projects
• Expert-level proficiency with TypeScript, React, and modern frontend development; deep understanding of performance optimization, state management, and React ecosystem best practices
• Strong experience with Ant Design component library, building reusable component systems, and maintaining design system consistency
• Proficient with Storybook for component development and documentation; experienced in building and maintaining component libraries
• Passionate about automated testing; experienced with Jest for unit/integration testing and Cypress for end-to-end testing, maintaining high test coverage
• Comfortable with modern build tools (Webpack, Vite), bundling strategies, and frontend performance optimization

• Experience with design tools (Figma, Sketch) and translating designs into pixel-perfect implementations
• Understanding of accessibility standards (WCAG 2.1) and building inclusive interfaces for all users
• Experience with data visualization libraries (D3.js, Recharts, Plotly) for building complex dashboards and analytics interfaces

3. Technical Leadership

• Proven ability to design component architectures for scale, maintainability, and reusability; make sound technical tradeoffs between complexity, time, and quality
• Tackle ambiguous, complex problems with innovative solutions; comfortable diving deep into unfamiliar codebases or technologies
• Track record of helping other engineers grow through code reviews, pairing, documentation, and technical guidance
• Drive initiatives from concept to completion without waiting to be told what to do; comfortable with autonomy and accountability

4. Collaboration & Communication

• Strong technical writing skills; produce clear documentation, technical specs, and design proposals that bring clarity to complex topics
• Thrive in distributed team environments; experienced working across time zones with async communication as default
