Join our team as a Senior Data Platform Security Engineer!

Yes, you can! That's our attitude towards our work, ambitions, ideas, and relationships. We at Luminor believe that anyone has the potential to achieve big things and encourage everyone to achieve them, professionally and personally.

We’re looking for a hands-on Senior Data Platform Security Engineer to help us build and run secure, modern data platforms.

In this role, you’ll combine security engineering and architecture – designing solutions while also implementing them in real environments. You’ll work closely with data engineers, platform teams, and cloud experts to ensure security is built in, automated, and always enforced.

How You Will Make an Impact:

• Design security controls across AWS, SaaS, and on-prem data platforms
• Work hands-on with AWS services (IAM, KMS, S3, logging)
• Implement data protection (encryption, masking, fine-grained access control)
• Design secure data flows and access patterns across environments
• Build security controls using Infrastructure as Code (Terraform)
• Develop reusable security guardrails and baseline configurations
• Integrate security into CI/CD pipelines (IaC scanning, secrets detection, policy-as-code)
• Automate compliance and enforcement wherever possible
• Perform threat modelling and security reviews
• Improve logging, monitoring, and detection capabilities
• Support audits, vulnerability remediation, and regulatory requirements
• Work closely with engineering, architecture, network, cloud platform and risk teams
• Help teams adopt secure-by-default practices
• Contribute to long-term improvements in platform security

• Strong experience in hands-on security engineering (with architectural thinking)
• Practical AWS security experience (IAM, KMS, logging, networking)
• Experience with Infrastructure as Code (Terraform, CDK, or similar)
• Familiarity with DevSecOps practices and CI/CD pipelines
• Experience building automated security controls and guardrails
• Scripting skills (Python, Bash, or similar)
• Good communication skills and a pragmatic mindset
• Fluent English is required in spoken and written communication due to working on the Pan-Baltic level

Nice to have

• Exposure data platforms (data lakes, DWH, analytics) and legacy data platforms (Oracle, SAP) is a plus

• Flexible working hours, Hybrid work, and the possibility to work from anywhere in the EU, Iceland, Switzerland, and the UK (in total 90 days per year)
• Teams that go outside Pan-Baltic borders, where people value challenging work together with good humor and having fun
• You’ll be joining a team where things move fast, ideas flow freely, and change is part of the everyday. It’s a dynamic environment that keeps you learning, growing, and never bored
• Additional weeks of vacation are available to all employees who have been in the company for 1 year or more
• We care about giving back to society, therefore, you will get additional days off for volunteering purposes
• Luminor offers 30 fully paid calendar days for military training every year
• A competitive benefits package in addition to your salary that includes health insurance after the first 3 months pass in all three Baltic states, as well as Health days in case of your absence due to sickness without a doctor's note needed
• Access to tools and resources that help you feel good and be productive at work and in life
