• You will work with a modern cloud-native stack including Go, GCP, Kubernetes and Docker.
• You get a genuine voice in shaping technical decisions, architecture and how your team works.
• Lendo is entering an exciting phase with new products and exciting product initiatives ahead.
• You will join a collaborative Product & Tech organization where your ideas are valued and your expertise makes a real impact.

Your Challenge

As a Senior Backend Engineer, you will design, build and continuously improve scalable backend services that power Lendo’s digital experiences.

You will

• Design, build and optimize scalable Go microservices.
• Take end-to-end ownership of backend solutions and contribute to architecture within your domain.
• Build reliable, maintainable and well-tested services that can scale with customer and business needs.
• Work with asynchronous communication and messaging using AMQP.

The Team and Workplace

Our backend platform is built around Go microservices and AMQP for asynchronous messaging.

We operate in a cloud-native environment using Docker, Kubernetes and Google Cloud Platform (GCP), supported by modern CI/CD pipelines.

Our focus is on building scalable, maintainable and reliable services while continuously evolving our architecture and engineering practices.

About You

We are looking for a senior backend engineer who combines strong technical skills with a pragmatic mindset, curiosity and a genuine sense of ownership.

You have

• Several years of professional experience in backend development and production systems.
• Strong hands‑on experience with at least one backend programming language. Go is highly relevant, but we are open to engineers with other strong backend backgrounds who can learn quickly.
• Experience designing and building scalable backend systems, ideally using microservices.
• A strong understanding of software architecture, scalability and system reliability.
• Experience with technologies such as Docker, Kubernetes and Git.
• Experience with CI/CD, for example GitHub Actions or similar tools.
• A strong quality mindset where testing, code reviews and maintainable code are a natural part of your work.
• An understanding of how to build systems that are reliable, observable and able to scale.
• The ability to take ownership of technical solutions and drive them forward.
• A collaborative mindset and an interest in sharing knowledge and continuously improving.

Experience with AMQP, GCP and Go is particularly relevant, but we value your engineering mindset and willingness to learn more than knowing every tool already.
