Frontend / Fullstack Software Engineer

General Description Of The Role We are looking for a Frontend/Fullstack Software Engineer (frontend-heavy) to join our Customer Service Experience (CSX) team. CSX builds and operates the internal back-office tools that customer support and fraud prevention agents rely on every day to keep our marketplaces safe and efficient. You will work in a autonomous product team where your contributions have direct, visible impact. The team owns the full stack - from the React/TypeScript frontend built on our shared WARP design system (warp-ds.github.io/docs/), to the Kotlin backend powered by CQRS event sourcing and domain-driven design. We are in the process of expanding CSX into the central hub for all back-office UI and workflows across the organization, which means there is significant room to shape both the product and the technical direction. This is a hands-on engineering role in a team that values pragmatism, ownership, and shipping over process. You will collaborate closely with your Engineering Manager, Product Manager, Designer, and Engineering peers, with a short feedback loop from ideation to production. Main Responsibilities Design, build, and maintain user-facing features in the CSX domain - Including our React/TypeScript frontend as well as any other user interface solutions we deliverEnsuring a polished and efficient experience for our internal usersContribute to the Kotlin backend - building APIs, integrating with downstream services, and evolving our event-sourced architectureTake ownership of features end-to-end: from technical design through implementation, testing, deployment, and monitoringCollaborate with Product and Design to translate user needs into well-crafted solutions, using the WARP design system (warp-ds.github.io/docs/) as the foundationImprove developer experience, tooling, and code quality within the teamParticipate in on-call rotations and incident response for the services we ownContribute to the team’s strategic evolution as CSX grows its scope to cover more backoffice domains (moderation tools, claims handling, compliance workflows) Relevant Qualifications & Experiences Solid experience with modern frontend development: React, TypeScript, and component-based architecturesExperience with backend development or willingness to learnComfortable working across the full stack - you do not need to be an expert in everything, but you are curious and willing to go where the problem isFamiliarity with modern development practices: CI/CD, automated testing, code review, trunk-based developmentExperience building internal tools or back-office applicationsExperience with design systems Personal Attributes Self-driven and comfortable with autonomy - you thrive in a small team where you own your work and make decisionsPragmatic problem solver who favors shipping over perfection, while maintaining quality where it mattersCollaborative and communicative - you share context, ask for help, and give constructive feedbackCurious about the domain and the users - you want to understand the “why” behind what you buildComfortable with ambiguity and change - CSX is evolving, and you see that as an opportunity rather than a riskSolution-oriented mindset - you think in terms of user outcomes, not specific technologies. While the current stack is React/TypeScript, you recognize that the best interface for a workflow might be a traditional UI, an AI agent, a CLI tool, or something entirely newForward-leaning and eager to adopt new technologies - We always strive to raise the bar of what small teams can deliver and to solve our problems in the most efficient way possible.
