Job description

Senior Backend Developer (Node.js/Nest.js)

Hello,
We are called People More because we treat our employees with respect, but also because the projects we work on are for people and should be easy and pleasant to use. We are technological, but we look at the bigger picture :)
People More has been in existence for over three years and is an offshoot of one of the country's oldest interactive agencies - Insignia. The company is made up of people with a huge client base in the country and abroad, for whom we build projects from scratch (UX, UI, frontend, backend, mobile) or in part. We work directly for our clients and also support our partners in their own solutions. This ensures a wide range of projects and the ability to change! We work with clients all over the world.
For the project that we are working on with our foreign partner, we are looking for Senior Backend Developer (Node.js/Nest.js).

Your duties will include:

• Design and develop backend services using Node.js and NestJS, including module architecture, dependency injection, and middleware.
• Build and maintain microservices-based backends and distributed systems.
• Implement messaging systems using AMQP (RabbitMQ) and MQTT for asynchronous communication.
• Develop event-driven architectures, applying patterns like CQRS and event sourcing.
• Apply OOP design patterns and SOLID principles to ensure scalable and maintainable code.
• Write comprehensive unit and functional tests to guarantee code quality.
• Collaborate with cross-functional teams to deliver robust solutions.

Requirements that must be met:

• Minimum 7 years of experience as backend developer.
• Node.js / NestJS: Strong proven experience in backend development with NestJS.
• Microservices: Practical experience with distributed systems.
• Messaging Systems: Hands-on with RabbitMQ, MQTT.
• SOLID Principles: Deep understanding and application.
• Testing: Unit and functional tests.
• CI/CD: Experience with pipelines for continuous integration and deployment.
• Kubernetes: Container orchestration and deployment.
• TypeORM: Familiarity with ORM tools for Node/NestJS.
• Dockerization: Packaging applications in Docker containers.
• Idempotency: Applying idempotent principles in APIs and messaging.
• Very good English and Polish

What we offer:

• We are open and honest and we solve problems instead of generating them.
• Maybe it’s obvious, but we really respect our employees and associates. We used to be software developers, too, and we appreciate that job!
• A small team
• An international working environment and international projects
• Private medical care
• Sports card
• Training courses
• Work that is 100% remote (unless you prefer another system)

We have an office in Krakow, but if you like to work remotely, that’s absolutely fine. Over the next few months, we plan to continue working this way. After that, you decide according to what you prefer. We are OK with fully remote work. For us, you can be located anywhere. :)

Why it’s a good idea to work with People More?

• If you are not satisfied with your work or your tasks, we’ll find a way out together!
• If you get bored, we will offer you a new product and new, fascinating tasks
• We will work on your brand together: you will get an opportunity to attend conferences, including as a speaker, and we will help you publish in recognized magazines and online
• We will facilitate your access to challenges that are usually difficult to get
• At any time, you can talk directly to the board of People More—we talk your language because the company’s founders are software developers and designers!

What does the recruitment process look like?

• A friendly remote initial interview
• A remote technical talk
• The decision to work together!
