About the job

Graylog is currently recruiting for a Senior Java Developer to join our engineering organisation during an exciting period of growth.

The Senior Java Developer (everyone is a Software Engineer here by the way) will focus on the backend end of our core solutions Graylog Open & Graylog Enterprise both on-prem and in the cloud in Java together with your team.

You will collaborate with peers on needed requirements with the product, and design, and even get into the architecture when needed.

Java will be your preferred language (among others) and you will be passionate and take a sense of pride in designing, developing, and maintaining high-quality code using Java technologies (Java 17).

As a Senior Java Developer here at Graylog you will have the opportunity to make a significant contribution and impact on our products. Your work can and will have a huge impact on our user’s experience.

By joining Graylog, you will be part of a passionate team that despite working primarily remotely, values connections and likes to spend time, grow, and learn from one another.

Work as you prefer: This position can be based anywhere in Germany (we have offices in Hamburg & Munich) or potentially in the UK (we have an office in London) for the right person and will report to our Engineering Manager based in Hamburg, Germany.

Additional responsibilities will include but are not limited to;
  • Work on the backend of the Graylog products in Java together with your team.
  • Lead the design, implementation, and delivery of successful large-scale, critical and/or highly complex software
  • Focus on data management, performance optimization, authentication, permission handling, scheduling, and architecture.
  • Adapt and improve core elements of Graylog to fit well into on-premises and cloud environments.
  • Implementation of OpenSearch management features from within Graylog.
  • Backend design, code reviews, automated tests.
  • Coach and mentor your peers.


Some of the technology we use at Graylog;
  • Java 17, OpenSearch, ElasticSearch, and MongoDB on Linux
  • Maven, IntelliJ, Git, Github, Jenkins


Key Deliverables;
  • Within the first 2 months you can expect to complete smaller issues and fix minor bugs to learn about our processes. You’ll have your work reviewed by an experienced core engineer and merged to contribute to the product.
  • In the first half year, you’ll start working on your first feature project together with peers from the team. You’ll learn about a specific area of the code and actively contribute to its implementation whilst sharing your progress with the team regularly
  • Within 6-12 months you’ll have your first feature project merged into a release and actively contribute to the release process (by supporting our testing, sharing information, etc.).


A little bit about you;
  • 4+ years of professional programming experience, at least in one challenging project
  • Experience producing high-quality Java-based application code
  • Relevant experience in other programming languages (e.g. Golang would be advantageous)
  • Experience with OpenSearch/ElasticSearch or another search technology in a production environment
  • Ideally experience with the OpenSearch/ElasticSearch API, Mappings and Index templates
  • Preferably knowledge of web and enterprise environments. Practical experience in the maintenance of an Open-Source project would be ideal
  • Proficient English communication skills
  • Willingness to occasionally travel to our Hamburg, Germany office.


Just some of the reasons why to join Graylog;
  • Opportunity to work with a globally distributed and diverse team
  • Grow and develop professionally and personally in a fast-growing environment
  • Choice of latest equipment to help you succeed
  • Monthly allowance to support your commute costs and support outfitting your work-from-home environment
