Major offices in Sweden (HQ), Greece, India, Canada, Israel, Poland, UK, and Uruguay. The Team: Platform Services At the heart of this technology is the Platform Services team, a highly technical group responsible for maintaining and evolving the foundational aspects of the Etraveli Group platform. Our mission is to ensure we have a robust environment to build, deliver, and run services—from the very first lines of code in a project to maintainable services running in production, whether in AWS or our own datacenters. We manage our CI/CD setup and cloud infrastructure using Infrastructure as Code (IaC), providing project templates and architectural support to development teams and strategically important projects. Today, the team consists of a collaborative mix of cloud infrastructure specialists and tech-focused senior developers. The Role As we grow and expand our support for new teams and projects, we are looking for a Senior Engineer or Hands-on Architect to strengthen our ranks. While the team handles infrastructure, your focus will be on the software side of building services: code, design, system architecture, and CI/CD. In this role, you will certainly draw boxes and arrows on whiteboards to map out designs, but more importantly, you will write and update the code within our templates and CI/CD pipelines to support our developers. You will be a key voice in discussions—both within the team and across the organization—on how to best design and solve complex technical tasks. Requirements To be a good fit for this role, we believe you possess the following qualifications: Experience: At least 10 years as a software developer and/or architect (likely more). Java Expertise: Extensive experience as a Java backend developer, very comfortable in a senior capacity. Polyglot Mindset: Experience with programming languages beyond just Java. Mentorship: You enjoy supporting other developers and can discuss complex software solutions with both teams and stakeholders. CI/CD & Kubernetes: At least some experience with CI/CD (and a willingness to become an expert) and a strong understanding of Kubernetes—including the ability to write and troubleshoot manifest files independently. Broad Technical Interest: An interest in the underlying infrastructure required to run services, as well as a passion for service architecture and IaC (without being "married" to a single tool). Tech Stack Knowledge: Meaningful experience in several of the following: AWS, Linux, shell scripting, Git, Jenkins, Groovy, Typescript, React, Python, MySQL, Couchbase, Kafka, RabbitMQ, Terraform, CDK, CloudFormation, Gradle, Spring Boot, Kubernetes, Helm, OpenSearch, Prometheus, Grafana, observability, security, networking, and testing. Communication: Comfortable speaking and writing in English. Ready to take off from day #1 Thorough On Boarding Process We are building a stellar onboarding adventure just for you, spanning your first 120 days, including access to learning resources, Q&A sessions with our CEO and a buddy program. Competitive Benefits We pay fairly and align compensation with your role's impact on the company. Referral bonus, pension and insurances are also applicable, with some variations across our locations. Wellbeing & Community In order to be the best version of you every day, you need an environment that provides for your wellbeing. From breakfast & good coffee to start your day to healthcare, employee assistance plans and team bonding events we've got you covered! Opportunities for Development You will find extensive learning opportunities, team training and workshops connected to your role as well as guidance from renown leaders, all provided in a fast pace environment with flat hierarchies. Hybrid Work We want you to enjoy the best of all worlds and we know that doesn't always mean working at the office. We have a hybrid policy, including working from anywhere 2 weeks every year. Diversity disclaimer At Etraveli Group we value diversity; we pride ourselves on being a company represented by people of all different backgrounds. During hiring, we are committed to ensure equality and promote diversity in the workplace at every selection stage.
