Cover Letter Sample

I am writing to express my strong interest in the Senior Frontend Engineer, Ads Creative position at Reddit. With over 5 years of experience building complex web applications using JavaScript, TypeScript, and React, I have a proven track record of delivering high-impact frontend features from concept to launch. I am particularly drawn to Reddit's mission of fostering authentic communities and the opportunity to shape advertiser tools that combine AI-powered recommendations with intuitive interfaces.

In my previous role, I owned the technical design and implementation of a campaign management platform, working closely with product, design, and data science teams to translate ambiguous requirements into polished, performant user experiences. I have extensive experience with state management, component architecture, and accessibility, and I regularly use AI coding tools like Cursor to accelerate development while maintaining code quality.

I am excited about the chance to contribute to Reddit's Ads Creative & Recommendations team, where I can leverage my skills in frontend architecture, collaboration, and mentorship to build reliable, user-friendly tools that help advertisers succeed. I look forward to the possibility of discussing how my background aligns with Reddit's goals.

Sample Interview Questions

Can you describe a complex frontend feature you owned from technical design through launch?

I led the development of a real-time ad creative editor that allowed advertisers to preview and iterate on campaigns. I designed the component architecture, managed state with Redux, and integrated APIs to fetch and update assets. The project involved close collaboration with design and backend, and I used A/B testing to optimize performance, resulting in a 20% increase in advertiser engagement.

How have you handled ambiguous product requirements in past projects?

In a project to build a recommendation widget, initial requirements were vague. I proactively partnered with product and design to create prototypes and gather user feedback, iterating on the design. I also broke down the problem into smaller milestones, ensuring we made steady progress while remaining flexible to new insights.

Describe your experience with AI or machine learning interfaces. How would you approach integrating ML recommendations into a user-facing tool?

I've built interfaces for ML-driven content suggestions where users could refine results via sliders and tags. For Reddit's creative tool, I'd focus on making the ML output transparent and controllable, allowing advertisers to adjust parameters and see real-time previews. I'd work with data science to understand model capabilities and design UI components that surface confidence levels and allow iterative feedback.

How do you ensure code quality and maintainability in a fast-paced environment?

I enforce code reviews, write comprehensive unit and integration tests, and maintain documentation. I also advocate for modular architecture and refactoring technical debt regularly. For performance, I use tools like Lighthouse and React Profiler, and I promote accessibility standards (a11y) from the start.

Can you give an example of how you mentored other engineers?

I organized weekly frontend office hours where team members could ask questions about React patterns, state management, or testing. I also paired with junior engineers on complex ticket, breaking down tasks and reviewing their PRs with detailed feedback. One mentee later led a major component refactor, improving team velocity.

Role Description

We’re looking for a senior frontend engineer with deep JavaScript, TypeScript, and React experience to help shape the next generation of Reddit’s advertiser tools.

You’ll independently own complex and sometimes ambiguous areas of the product, from technical design through launch and iteration. You’ll work closely with product, design, data science, machine learning, and backend engineering to turn sophisticated capabilities into workflows that feel simple and dependable.

This role is a strong fit for someone who cares about both the architecture behind a frontend system and the details that make a product intuitive, fast, accessible, and maintainable.

Partner with product and design to work through ambiguous requirements and make sound product and engineering tradeoffs.
Develop reusable frontend patterns and components that support a unified campaign creation experience.
Instrument experiences, evaluate results, and use experiments and product data to guide iteration.
Raise the quality of the codebase through thoughtful architecture, testing, observability, performance work, and accessibility.
Provide high-quality code reviews and technical guidance, and help other engineers grow.
Collaborate across frontend, backend, data, and machine learning systems to deliver reliable end-to-end experiences.

Required Qualifications

5+ years of experience building production web applications with JavaScript, TypeScript, and React.
Comfort using Codex, Cursor, Claude, or comparable agentic coding tools in day-to-day software development.
A track record of independently delivering complex frontend projects from technical design through launch and iteration.
Sound judgment in frontend architecture, state management, component design, testing, and API integration.
Experience building polished user interfaces with close attention to usability, performance, accessibility, and maintainability.
Ability to work effectively through ambiguous product and technical problems.
Strong communication and collaboration skills across engineering, product, design, and data disciplines.
Experience using instrumentation, experimentation, or product metrics to understand and improve user experiences.
A habit of improving engineering quality through code reviews, documentation, and technical mentorship.

Bonus points

Experience building advertising, campaign management, creative tooling, or other complex business applications.
Experience designing interfaces for generative AI, machine learning, or recommendation systems.
Familiarity with asset management, media upload, image editing, creative versioning, or content generation workflows.
