Overview

Wallapop is a Barcelona based scale-up driven by the purpose to empower people to embrace a more conscious and human way of consumption. We believe in a world where collaborative economy is mainstream. This is what drives us.

Wallapop operates in Spain, Italy and Portugal, offering a catalogue of several hundreds of millions of products and services. Powered by technical innovation and continuous improvement, we bring together the scale & trust of classifieds with the marketplace’s convenience & reach. Our mission is to enable a connected trade ecosystem, making 2nd-hand the norm through smart use of technology.

Backed by top investors such as Accel, Insight Partners & Naver Corp we bring our total valuation to 806 million EUR and are embarking on our international journey with the aim to become the world’s best unique goods trading platform.

The Challenge

Some of the interesting things we are currently doing include finding new ways to handle the complexity or improve resiliency. We leverage various AWS technologies (compute, storage, etc.) to meet our objectives. At Wallapop, as a Backend Engineer, you'll own team microservices, fully embracing the DevOps philosophy. Our tech stack includes the following:

• Kotlin & Java
• Spring Boot & Ktor
• MySql, DynamoDB, Redis & RedShift
• Docker
• AWS: S3, ECS, RDS, Lambdas, CloudWatch, MSK, SES, CloudFront & more

What You Will Do

• Write robust, scalable code in Java or Kotlin, depending on your team's stack
• Develop new features using Domain-Driven Design (both tactical and strategic design)
• Address and refactor legacy components
• Testing all the things! Testing is a must, especially if you want to avoid those friendly reminders during the code review

What We’re Looking For

• Strong problem-solving skills and critical-thinking abilities
• Quality-driven mindset with keen attention to detail and pragmatism
• Adaptable and eager to learn and grow

Do note that all our jobs are Barcelona based. We follow a hybrid model where flexibility rules. We commit to a minimum of 6 days per month in the office. Each team self-organizes to decide on cadence and in-person/remote rituals.
