Senior Software Engineer (Java / Kotlin) - Operations Automation

Salary : €18,850 - 25,900 monthly

Azienda : Allegro Tipo Lavoro : Full Time Italy

About the Job

At Allegro, we operate at a massive scale where performance, reliability, and developer efficiency are paramount. Within our multi-product platform team, we design and maintain the critical infrastructure, low-code engines, and shared technical solutions used by other engineering teams to build secure and auditable internal tools across the entire ecosystem.

Our internal platform solutions are utilized company-wide to streamline data access and simplify admin tool creation. This environment demands exceptional complexity management, structural scalability, and out-of-the-box architectural thinking to eliminate repetitive developer bottlenecks and ensure that our customer support department can operate without disruption.

The Role

As a Senior Software Engineer, your primary focus will be the development, maintenance, and architectural evolution of our core backend platform services and low-code infrastructure. This is a highly impactful, well‑rounded role where you will ensure the high availability, security, and stability of systems that power internal applications company‑wide. You will help the organization scale efficiently while keeping technical debt to a minimum.

Key Responsibilities:

• Design & Development: Architect, develop, and scale core platform services, messaging components, and internal development tools. The primary stack is backend‑focused (Kotlin/Java, Spring, Kafka, queuing systems, PostgreSQL, MongoDB, Cloud - Azure/GCP, Kubernetes/Docker), with the opportunity to occasionally collaborate on the frontend (TypeScript/React) or AI‑driven services (Python).
• Stability & Reliability: Actively monitor, optimize, and deep‑dive into platform systems to ensure maximum stability and safeguard our internal SLAs. You will share responsibility for system availability by participating in our casual on‑call duty rotation.
• Enabling Internal Teams: Provide a robust technical foundation and clear abstraction layers so other teams can build and deploy their tools swiftly, securely, and consistently.
• Project & Team Leadership: Lead software development initiatives, supervise and mentor other team members, and document software thoroughly.
• Stakeholder Collaboration: Analyze the needs of our internal users to deliver features that accelerate company‑wide development and eliminate repetitive manual work.

We are looking for people who:

• Have Strong JVM Engineering Fundamentals: Demonstrate deep expertise in backend engineering with Kotlin/Java and have proven experience with Kafka, queuing systems, and PostgreSQL.
• Are Versatile & Tech‑Agnostic: Are open to a very diverse environment. While your primary focus is the JVM stack, you are enthusiastic about collaborating with team members who touch frontend components (React/TypeScript) or AI assistant architectures (Python)
• Thrive under High Responsibility: Understand the business criticality of internal platform tools. You care about visual consistency, high security, and deep auditability, knowing that system stability directly impacts our daily customer service operations.
• Value Quick Feedback & Continuous Impact: Enjoy working closely with an internal customer base, allowing you to receive rapid feedback on your work and see its immediate organizational impact.
• Are Forward‑Thinking & Innovative: Are open to experimenting with cutting‑edge efficiency boosters. Our team actively explores integrating AI Agents and LLMs into our internal tooling and workflows to optimize daily operations.
• Possess a Pragmatic, Problem‑Solving Attitude: Look for the best tool for the job, maintain an analytical mindset, and focus on driving automation over repetitive manual task
• Communicate in English: At a B2 level or higher.

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 .

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.
• PLN 18 850 - 25 900
• Annual bonus based on your annual performance and company results.
• Long term discretionary incentive plan based on Allegro.eu shares (restricted stock units).
• Our team is based in Poznań and Warsaw.

#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!
