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.

GOT YOUR ATTENTION?Apply now! We will review applications continuously as they come in. The deadline for this role is 30th August 2026

A few words from Engineering Manager, Alexander Thorén:

"CSX is a highly specialized and fast-moving team, leveraging the bleeding edge of technology to deliver efficient workflows for our customer-service agents and internal users. Since our user base consists of our direct colleagues, we are able to stay highly innovative in how we deliver solutions. We have full control of our product and enjoy the trust from our users to ensure their work is as fast and efficient as possible. It's quite an exhilarating experience going from an idea to a full-fledged product feature within a day!"

QUESTIONS?Alexander Thorén, Senior Engineering Manager, is happy to tell you more about the daily work and answer any questions you may have via LinkedIn / alexander.thoren@vend.com

• Developing scalable visualization components for device relationships, floorplans and system topologies

• Writing and maintaining tests to ensure quality and reliability

• Contributing to frontend architecture and participating in design and code reviews

• Working with AI-assisted development workflows, including reusable AI skills, agent definitions and specifications

• Reviewing and validating AI-generated code to ensure correctness and maintainability

• Continuously improving frontend performance, responsiveness and development practices

About you

To succeed in this role, you have solid professional experience in frontend development and are comfortable taking ownership of technically complex features.

Requirements:

• At least 5 years of professional experience in frontend development or a similar role

• Strong proficiency in JavaScript and TypeScript

• Extensive experience working with React

• Strong understanding of programming principles, design patterns, modern web protocols and web security

• Experience analysing and troubleshooting technical issues

• A strong understanding of clean code, frontend performance and optimization

• Experience integrating AI-assisted workflows into frontend development, such as code review, test generation or automation

• Experience creating and maintaining executable specifications or living documentation alongside evolving code

• Familiarity with Model Context Protocol, MCP, and connecting AI tooling with internal systems

• Experience using AI-assisted code review as part of a development workflow

Nice to have:

• Experience with Node.js, other programming languages or full-stack development

• Experience with Redux, React-Redux or redux-saga

• Experience with styled-components or similar styling solutions

• Experience working with multimedia such as video, audio or image optimization

• Experience developing interfaces for networking, mobile or IoT products

• Experience with visualization libraries for topology maps, hierarchical graphs or interactive layouts

• Experience implementing interactive UI functionality such as zooming, panning, snapping or node-link editing
