Employment: Full-time, Senior 

We're looking for a Senior Atlassian Specialist to own the administration, customization, and continuous improvement of our Atlassian ecosystem (Jira, Confluence, Jira Service Management, and related apps). You'll work across engineering, product, and operations teams to keep workflows efficient, scalable, and aligned with how the business actually works — combining hands-on administration with light development/scripting and process consulting.

What You'll Do

• Administer and maintain Jira, Confluence, and Jira Service Management (Cloud and/or Data Center), including user management, permissions, and instance health.
• Design and customize workflows, schemes, screens, and automation rules to match evolving team processes.
• Extend platform capabilities with scripting (e.g., ScriptRunner/Groovy) and manage third-party app integrations from the Atlassian Marketplace.
• Lead migrations, upgrades, and instance consolidations with minimal disruption to teams.
• Partner with stakeholders across departments to translate business and process needs into Atlassian configuration.
• Establish governance, naming conventions, and best practices to keep the instance scalable as the company grows.
• Troubleshoot issues, manage integrations (CI/CD tools, SSO, Slack, etc.), and provide ongoing support and training to end users.

Who We're Looking For

• 5+ years of hands-on experience administering and configuring the Atlassian suite (Jira, Confluence, JSM) in a production environment.
• Proven experience with workflow design, automation rules, and permission schemes at scale.
• Scripting experience (ScriptRunner, Groovy, or similar) for custom logic and integrations.
• Experience leading migrations (Server/Data Center to Cloud, or instance consolidations).
• Strong stakeholder management skills — comfortable translating business needs into technical configuration.
• Atlassian certifications (ACP-100, ACP-120, or similar) are a plus.
• Based in the EU, with the ability to work remotely and overlap with core team hours.
• Fluent English, written and spoken.

Jira, Confluence, Jira Service Management, Atlassian Marketplace apps, ScriptRunner/Groovy, SSO/identity integrations, CI/CD tool integrations.

We're looking for a Middle+ Data/Databricks Engineer to join our data team and take ownership of pipelines built on Databricks. You'll design and run production-grade ETL/ELT workloads, work with the lakehouse (Delta Lake) architecture, and partner closely with analysts, data scientists, and business stakeholders who rely on the data you deliver. "Middle+" here means roughly 3–5 years of hands-on data engineering experience: you can own a pipeline end to end with minimal supervision, make sound design decisions, and are starting to mentor more junior engineers — without yet carrying full architectural ownership of the platform.

• Build and maintain CI/CD for Databricks notebooks and jobs (Databricks Asset Bundles, Repos, Git-based workflows).
• Orchestrate pipelines with Databricks Workflows, Azure Data Factory, Airflow, or similar tools.
• Monitor job performance and cluster costs; troubleshoot failures and optimize for reliability and spend.
• Implement data quality checks, testing, and monitoring for critical datasets.
• Collaborate with analysts, data scientists, and business stakeholders to translate requirements into data models.
• Participate in code reviews, document technical decisions, and help shape engineering best practices.

• Experience with at least one major cloud platform — Azure, AWS, or GCP (Azure Databricks is a plus).
• Familiarity with pipeline orchestration tools (Databricks Workflows, ADF, Airflow, or equivalent).
• Working knowledge of Git and CI/CD practices for data engineering.
• Understanding of data governance, access control, and security basics (Unity Catalog is a plus).
