Job description

About the job:

We are seeking a talented, open-minded, and ambitious Junior Software Engineer (Backend / Mobile) to join our Listings (Mobile Apps) team. You won't just be writing code for the sake of it; you'll be a key contributor to the critical path of our iOS and Android apps, directly impacting millions of users through our Listings and Filters features. The team is currently driving a massive transformation, migrating our backend services to Kotlin and JVM, while building a next-generation shopping experience that will adapt the UI to users’ needs and use cutting-edge technologies (e.g. LLMs) to refine their search results and help them select the perfect product on our shopping platform.

Your mission? To accelerate experimentation and deployment in our mobile apps by combining strong backend capabilities with a passion for mobile development. You’ll get a unique opportunity to dive deep into Kotlin, Spring Boot 4, and Spring GraphQL by providing data and building application UI on the backend, while dedicating a significant part of your time to mastering mobile technologies (Android and/or iOS). Our team is highly experienced, and we are looking for someone who brings fresh ideas, a hunger to learn, and the flexibility to adapt to a changing tech landscape. If you're itching to take end-to-end ownership of features and want to tie your professional future to the dynamic world of mobile app development, you've found the right place.

Important things for you:

• The salary range for this position depending on the skill set is as follows (contract of employment, tax-deductible cost):
• Annual bonus based on your annual performance and company results.

What's in it for you:

• Well-located offices (with e.g. fully equipped kitchens, bicycle parking, terraces full of greenery) and excellent work tools (e.g., raised desks, ergonomic chairs, interactive conference rooms).
• A 16" or 14" MacBook Pro or corresponding Dell with Windows (if you don't like Macs) and all the necessary accessories.
• A wide selection of fringe benefits in a cafeteria plan - you choose what you like (e.g., medical, sports or lunch packages, insurance, purchase vouchers).
• English classes that we pay for related to the specific nature of your job.
• A training budget, inter-team tourism (see more here), hackathons, and an internal learning platform where you will find multiple trainings.
• An additional day off for volunteering, which you can use alone, with a team, or with a larger group of people connected by a common goal.

#goodtobehere means that:

• You will join a team you can count on - we work with top-class specialists who have knowledge- and experience-sharing in their DNA.
• You will love our level of autonomy in team organization, the space for continuous development, and the opportunity to try new things. You get to choose which technology solves the problem and you are responsible for what you create.
• You will value our Developer Experience and the full platform of tools and technologies that make creating software easier. We rely on an internal ecosystem based on self-service and widely used tools such as Kubernetes, Docker, Consul, GitHub, and GitHub Actions. Thanks to this, you can contribute to Allegro from your very first days on the job.
• You will be equipped with modern AI tools to automate repetitive tasks, allowing you to focus on developing new services and refining existing ones (also leveraging AI support).
• You will create solutions that will be used (and loved!) by your friends, family and millions of our customers.
• You will meet the Allegro Scale, which starts with over 1000 microservices, an open-source data bus (Hermes) with 300K+ rps, a Service Mesh with 1M+ rps, tens of petabytes of data, and production-used machine learning.
