Fullstack Developer

About Copernica

Copernica builds a flexible marketing automation platform that combines data-driven workflows with large-scale email delivery. Our products range from a full-featured Marketing Suite for advanced automation to SMTPeter for transactional email and MailerQ, our on-premise MTA for high-volume sending.

We serve both marketers and engineering teams who need control, scalability, and compliance.

We prefer steady progress in small steps, frequent validation, and continuous iteration. In this role, your impact is defined less by what you already know and more by how you think, learn, and approach complexity.

The role

As a Developer at Copernica, you work on improving and expanding our software. Depending on your interests and growth path, you may focus more on product functionality or on the underlying systems that ensure stability, performance, and scalability.

Your work may include:

• Developing and improving back-end functionality

• Contributing to front-end improvements where relevant

• Working with databases and APIs

• Building and optimizing integrations and supporting systems

• Analysing system behaviour and performance

• Translating insights into structural code improvements

Technical environment

We develop and operate our software and infrastructure ourselves. Our stack is strongly Linux-oriented and runs on Kubernetes. Depending on the team and your focus, you may work with:

• JavaScript

• PHP

• C++

• REST-based APIs

• Message queues and asynchronous processing

• CI/CD pipelines

• An in-house Infrastructure-as-Code platform

What we offer

We actively invest in knowledge sharing and collaboration:

• Regular in-office sessions covering both technical and commercial topics

• Space to test ideas, gather feedback, and present new features

• Hybrid working, with the option to work structurally from the office if you prefer

At the office, we focus on a pleasant working environment:

• Fresh lunch provided on-site

• Great coffee, a wide selection of drinks, fruit, and snacks

• Relaxation options such as pool, table tennis, or darts

• Informal moments to wrap up the week together in our lounge

• Team outings and shared activities

Requirements

What we value

We care most about how you think and work. You are likely to succeed in this role if you have:

• Strong logical and analytical thinking skills

• A problem-solving mindset and pattern recognition ability

• Curiosity and the ability to add value quickly

• A solid understanding of programming fundamentals

Technical experience helps you get up to speed faster, but strong analytical thinking and problem-solving skills form the true foundation for success in this role.
Much of our environment is developed in-house and is well suited to developers who want to understand how systems really work and how they can be improved. There is value in your keenness to understand the underlying mechanisms of our software and systems, as you rarely develop against a black-box. We rely on your willingness and ability to keep learning.
