Job description

Software Engineer 1 (Java / Kotlin) - Developer Tools

Location: Poznań, PL, 61-569

Team: Technology

Contract Type: Employee

About the job:

Allegro’s development teams boast more than 1700 IT experts solving problems at a unique scale and complexity. However, if you join us, you'll be joining a specific team that operates like a small, agile startup within our large organization.

Our team is strongly Developer Experience (DevEx) driven, focusing on the core tools and components that powers Allegro's software delivery lifecycle. We maintain the very heartbeat of our development process: from managing a massive selfhosted runners cluster and administrating Github enterprise to building tools that define how we build and release code. We are looking for a Software/DevOps Engineer who enjoys the intersection of software engineering and infrastructure, ensuring that our SDLC is fast, reliable, and scalable.

We are a versatile team with diverse competencies, handling everything from our own Java/Kotlin microservices (backed by MongoDB) to maintaining a central library that serves as the essential bridge between developers and our infrastructure. We are passionate about our internal users - the dozens of engineers who rely on our tools every day - and we work closely with them to ensure that CI/CD processes, from the first line of code to final deployment, are a seamless experience. You'll be joining a group where you can have a direct, daily impact on how hundreds of releases are handled across the company.

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 PLN 11 200 - 15 250.

Annual bonus based on your annual performance and company results.

Our team is based in Poznań.

We are looking for people who:

• Code in Java and / or Kotlin
• Are proficient in Linux and feel at home managing systems that operate at a massive scale
• Expect work that has a deeper meaning (not only tasks "management has commissioned") and want to enjoy its results
• Want to be proud of the code they create. They eagerly accept comments and share knowledge during code reviews
• Believe that "manual" is a bug – you automate everything (ex. using Ansible) and follow the Infrastructure as Code (IaC) philosophy
• Can look for effective solutions that solve business and technical challenges
• Can navigate GitHub and know how to build efficient, developer-friendly environments for CI/CD pipelines
• Want to expand their skills into containerization and orchestration to help us build even more portable and resilient systems
• Want to constantly develop and update their knowledge, not only regarding software, but also in other domains like Big Data depending on clients needs
• Know English at 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!
