About The Position

Giga has recently raised a $61M Series A and has several paying customers, including DoorDash. We’re building the next generation of customer experience — real-time AI agents that can understand emotion, resolve issues instantly, and scale across the world’s largest enterprises. It’s an exciting inflection point for the company. While we have been successful, we have larger ambitions. Our goal is to become the go-to AI platform for all enterprise automation, powered by our voice superintelligence. To achieve this, we need more great engineers. The work affects millions of people every day and our engineers have autonomy and make true impact. This opportunity is unique because we have brilliant founders, have found commercial success, and see a clear path to becoming a generational company. Some further info about us: Voice AI startup Giga raises $61M Series A DoorDash and Giga Partnership Giga builds AI agents trusted by the largest B2C companies in the world. Industry leaders like DoorDash trust Giga with their most complex support and operations workflows across voice, chat, and email. If being a part of this resonates with you, please apply! We're looking for a frontend infrastructure engineer to build the tools and systems that make our frontend engineers more productive. Your customers are internal engineers, not end users; you'll create design systems, developer tooling, and foundational abstractions that the rest of the team builds on. This isn't a product engineering role where you ship features to customers. You'll think about frontend API design, code quality infrastructure, and building reusable components that are a pleasure to use. If you've worked on a design systems team, frontend platform team, or developer experience team at a larger company, this will feel familiar. A few examples of what this role might tackle: Design system: Building and maintaining a component library with clean APIs, consistent patterns, and great documentation Developer tooling: CLIs, build tooling, and automation that speeds up frontend development workflows Code quality infrastructure: Type checking improvements, linting rules, testing utilities, and other guardrails that catch problems early Frontend architecture: Establishing patterns for state management, data fetching, and component composition that scale as the codebase grows As a staff engineer, you'll make decisions about our frontend foundations and drive adoption across the team. You'll balance building the "right" abstraction with shipping something useful now.

Requirements

Have 5+ years of frontend engineering experience, with time spent on infrastructure, platform, or design systems work
Have strong opinions about frontend API design—you care about how components are consumed, not just how they look
Enjoy building tools and abstractions that other engineers use daily
Think deeply about developer experience and take pride in making things easy to use
Are proficient in TypeScript and React, with experience building component libraries or shared packages
Can balance perfectionism with pragmatism
