Frontend Software Engineer Jobs in California (NOW HIRING)

The mission of the Developer Experience org is to design, develop, and support tools and processes that make common developer workflows efficient and reliable. 

AI-powered and agentic developer tools are changing what is possible, creating an opportunity to rethink how engineers write, test, review, ship, and operate software. At Reddit's scale, that means building tools that are not only more intelligent, but also faster, more reliable, easier to use, and grounded in strong engineering fundamentals.

This role sits at the center of that work: owning frontend development for Reddit's internal developer tooling, from understanding developer pain points and designing the right user experience to building scalable, maintainable interfaces that support the full path from the first line of code to the artifact released at the end of the process. You'll help explore new AI-powered workflows while continuing to build the core interfaces, platform capabilities, and engineering fundamentals that make developer tools useful, trustworthy, and reliable.

Some of our present and future challenges include:

• Designing and building the next generation of developer tooling, including agentic and AI-powered workflows.
• Improving developer velocity, confidence, and service reliability across Reddit Engineering.
• Building tools and workflows that make writing, testing, reviewing, and shipping code easier.
• Architecting and improving continuous delivery experiences for hundreds of engineers.
• Scaling our infrastructure, interfaces, and processes to serve a growing engineering organization.
• Understanding internal users' needs and turning that understanding into meaningful product and technical improvements.
• Investigating, building, and integrating novel technologies where they solve real problems for developers.

You'll draw on your frontend expertise, technical judgment, and leadership skills to build developer tooling that is smooth, reliable, easy to use, and valuable to a growing engineering organization. You'll work directly with engineers across Reddit to understand their pain points, shape solutions, incorporate feedback, and communicate the impact of the team's work.

• Work cross-functionally across Reddit Engineering to understand developer needs, quickly prototype solutions, and iterate based on feedback.
• Own frontend development for internal developer tooling, from solution design and implementation through launch and long-term maintainability.
• Build scalable, maintainable interfaces across both AI-powered developer workflows and the core non-AI systems engineers rely on every day.
• Lead high-impact projects across Reddit's developer tooling ecosystem by writing and reviewing code and design docs, aligning stakeholders, and making pragmatic technical tradeoffs.
• Improve the team's tools, processes, and best practices while raising the bar for quality, usability, and maintainability.
• Mentor engineers and help shape a roadmap that reflects real developer needs and delivers meaningful improvements to Reddit's engineering organization.

• 5+ years of hands-on, post-grad, non-internship professional software development experience, with frontend engineering as a core strength.
• Strong proficiency with modern frontend development using TypeScript or JavaScript. Experience with component-based frameworks such as React, Lit, or similar is valuable, but we care more about strong frontend fundamentals than any specific framework.
• Experience designing and building end-to-end web applications at scale, including user interfaces, API integrations, system design, testing, launch, and iteration.
• Hands-on experience using AI-powered developer tools and workflows as part of your own engineering practice, with curiosity and judgment about where these tools can meaningfully improve developer productivity.
• A track record of leading large, ambiguous projects that require cross-team collaboration, technical judgment, and clear ownership from problem definition through delivery.
• Strong software engineering fundamentals, including testing, code reviews, technical design, documentation, maintainability, and building scalable, well-designed systems.
• A user-focused mindset, with experience understanding user needs, working with feedback, and building reliable, usable, high-quality product experiences.
• Excellent communication skills, with the ability to collaborate effectively in a fully remote environment, influence technical direction, and navigate complex requirements across technical and non-technical stakeholders.
• Experience mentoring engineers, raising the technical bar, and helping teams make pragmatic tradeoffs.
• A self-directed, action-oriented approach. You are comfortable operating in ambiguity, learning quickly, and driving work forward even when the path is not fully defined.

• Experience working in developer experience, developer productivity, internal platforms, or developer tooling.
• Experience building tools or workflows for internal engineering users.
• Experience conducting user discovery, interviews, or feedback sessions with technical users.
• Experience measuring the impact of frontend work through experimentation, measured rollouts, analytics, or qualitative feedback.
• Experience designing and implementing internal platforms or reusable frontend systems.
• Experience with backend-adjacent technologies such as GraphQL, REST, HTTP, gRPC, or Go.
