Senior Backend Engineer | Remote Spain

TEKsystems General Services is looking for a Senior Backend Engineer to join a Platform Engineering team supporting one of Europe's largest retailers.

This is a fully remote role based in Spain.

Rather than building customer-facing applications, you'll be developing the services, APIs, and platform capabilities that engineering teams across the business rely on every day. The focus is on creating reusable solutions that improve the way software is built, deployed, and operated at scale.

What you'll be doing:

- Building backend services with Kotlin, Spring Boot, and MongoDB
- Developing APIs and microservices that support internal platforms and engineering teams
- Working in a cloud-native Azure environment, including AKS, App Services, Event Hubs, and Azure Monitor
- Automating deployments and infrastructure using GitHub Actions, CI/CD, and Terraform
- Driving best practices around observability, reliability, and developer experience
- Collaborating with engineers across the organisation to ensure platform capabilities are adopted and provide real value

We're looking for:

- Strong experience with Kotlin and Spring Boot




- Experience building microservices and distributed systems
- Azure cloud experience
- Knowledge of CI/CD, Infrastructure as Code, and DevOps practices
- Experience working on platform, infrastructure, or developer tooling teams is highly desirable
- Someone who enjoys solving problems that impact multiple engineering teams rather than a single product

About the team

You'll join a newly formed Platform Engineering Task Force that supports a variety of strategic engineering initiatives across the business.

The team is focused on two things:

- Building shared platform capabilities that help development teams move faster
- Creating space for innovation, including AI initiatives, experimentation, and proof-of-concept work

Typically, around 60% of your time will be spent on platform engineering activities and 40% on innovation-focused projects.

If you're interested in platform engineering, cloud-native technologies, and building solutions that have organisation-wide impact, we'd love to speak with you.
