Software Engineer 2 - Allegro Business

Allegro Business is growing fast and we are changing how companies buy online. We are building discount systems with an architecture capable of handling massive scale, which is crucial for acquiring clients in the Small and Medium Enterprises.

We need a Software Engineer (Java/Kotlin) who can jump straight into the action, take ownership of critical ongoing projects and help build the best product. No corporate fluff - just real engineering challenges and high impact.

About the job

• Own the architecture: You will design and scale backend services capable of handling complex business accounts and high transaction volumes.

• Lead & mentor: You'll set the bar for code quality, manage tech debt and share knowledge.

• Ship real product: You'll collaborate directly with Product Manager and UX Designer to turn complex requirements into clean, working software.

• Keep it rock-solid: You'll ensure our critical services run smoothly and reliably (and yes, help us keep our on-call rotation healthy).

Important things for you:

• Flexible working hours in the hybrid model (4/1) - working hours start between 7:00 a.m. and 10:00 a.m. We also have 30 days of occasional remote work.

• The salary range for this position depending on the skill set is as follows (contract of employment, tax-deductible cost):

  • PLN gross 14 600 - 20 825

  • Annual bonus based on your annual performance and company results.

• Our team is based in Kraków and Warsaw.

We are looking for someone who:

• Code in Kotlin or Java and are excited to master Kotlin in a production environment.

• Are open to diverse technologies, including Frontend (but you don't need to be a React master:))

• Want to be proud of the code they create: they value high-quality code reviews and engage in substantive discussions on software engineering best practices;

• Feel comfortable interacting with stakeholders and taking full end-to-end ownership of initiatives - from initial requirements gathering through implementation to post-deployment monitoring;

• Have a solid foundation in microservices architecture and feel at home working in cloud environments, understanding how to build scalable and resilient systems;

• Know English at at least B2 level.

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.

• Social events for Allegro people - Spin Kilometers, Family Day, Fat Thursday, Advent of Code, and many other occasions we enjoy.

And that's just the beginning! You can read more about the benefits here.

#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.

• You will become part of Allegro Tech - We speak at industry conferences, cooperate with tech communities, run our own blog (it's been over 10 years!), record podcasts, lead guilds, and we organize our own internal conference - the Allegro Tech Meeting. We create solutions we love (and can) to talk about!
