About the Job
Allegro is home to 1,700+ tech experts, but our team? We’re the ones building the backbone. We are part of the Core Platform, focusing on Server-Driven UI platform that allows our product teams to ship native experiences straight from the backend.
We’re currently scaling Opbox Studio, our next-gen React-based stack. But we’re not just building another internal tool. We are pivoting to an Agentic AI-first approach. This means we’re leveraging specialized AI agents to automate UI generation and layout logic, effectively redefining how Developer Experience looks at scale. If you hate repetitive tasks, have a product-oriented mindset, and want to build infra that "thinks" for other developers – you’re in the right place.
#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!
What we offer
- 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.
