• Frontend Focus: Strong, proven expertise in React, TypeScript, CSS/HTML, state management, and modern testing frameworks (Jest / Vitest / Playwright).

• Backend Proficiency: Solid hands-on experience in Kotlin with Spring Boot, REST APIs, and microservices architecture.

• Commercial experience working with MongoDB, SQL databases, and cloud environments (GCP preferred).

• Familiarity with agentic coding tools and assistants (e.g., GitHub Copilot, OpenCode).

• Proactive, relational, highly engaged, open-minded, and strong communication skills.

• Fluent in English (B2+).

Welcome Skills

• Exposure to Scala, Big Data engines (Apache Spark), or search technologies (ElasticSearch).

• Prior background in AdTech, PPC advertising, or large-scale e-commerce systems.

Key tasks

• Design, build, and maintain scalable React-based microfrontends for analytics dashboards and merchant tools with a focus on Accessibility (a11y) and Server-Side Rendering (SSR).

• Build high-performance backend microservices in Kotlin and Spring Boot to power real-time dashboards, benchmarks, and recommendation engines.

• Partner closely with Data Science teams to serve personalized recommendations and automated campaign insights.

• Participate in developing a distributed, event-driven cloud architecture for processing campaign data in real time.

• Maintain high engineering standards through automated testing (unit, integration, E2E via Jest/Vitest/Playwright), code reviews, CI/CD, and DevOps practices.
