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 deliver Ensuring a polished and efficient experience for our internal users Contribute to the Kotlin backend - building APIs, integrating with downstream services, and evolving our event-sourced architecture Take ownership of features end-to-end: from technical design through implementation, testing, deployment, and monitoring Collaborate with Product and Design to translate user needs into well-crafted solutions, using the WARP design system (warp-ds.github.io/docs/) as the foundation Improve developer experience, tooling, and code quality within the team Participate in on-call rotations and incident response for the services we own Contribute 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 architectures Experience with backend development or willingness to learn Comfortable 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 is Familiarity with modern development practices: CI/CD, automated testing, code review, trunk-based development Experience building internal tools or back-office applications Experience with design systems

Personal Attributes

Self-driven and comfortable with autonomy - you thrive in a small team where you own your work and make decisions Pragmatic problem solver who favors shipping over perfection, while maintaining quality where it matters Collaborative and communicative - you share context, ask for help, and give constructive feedback Curious about the domain and the users - you want to understand the “why” behind what you build Comfortable with ambiguity and change - CSX is evolving, and you see that as an opportunity rather than a risk Solution-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 new Forward-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.
