Join a senior data team building and evolving large-scale AWS data pipelines that power security products protecting home networks at massive scale.This is a full-time 6+ month assignment starting in September, with hybrid work: one day per week on-site in Keilaranta and otherwise remote. The team is looking for senior support to accelerate feature development, improve an evolving AWS-based data platform, and help tackle large-scale ETL and streaming challenges in a security-focused product environment.

In this role, you will:

• Design, develop, and operate high-volume batch and streaming data pipelines on AWS cloud-native infrastructure.
• Work hands-on with technologies such as Kafka, Spark, Lambda, S3, Python, SQL, and Terraform/Terragrunt to deliver new features and platform improvements.
• Help modernize data processing and warehousing capabilities by addressing scaling bottlenecks, ETL performance challenges, and architectural improvements.
• Collaborate closely with a small senior team to reduce backlog, improve reliability, and support the development and maintenance of data products.
• Contribute ideas that shape engineering practices, tooling, and platform evolution in an agile and supportive environment.

You will thrive if:

• You bring strong senior-level experience building data platforms on AWS, especially with distributed processing and large-scale data pipelines.
• You are comfortable working with streaming architectures and tools such as Kafka and Spark, and understand the realities of production-scale data systems.
• You have solid hands-on skills in Python, SQL, infrastructure as code, and CI/CD practices.
• You enjoy solving performance and scalability challenges, and can bring proven approaches rather than learning the fundamentals on the job.
• You value collaboration, communicate clearly in English, and like working in a team where good ideas are heard and acted on.
• Nice to have: Experience with utilizing AI in your own work
