At Lùkla, we partner with major European organisations to design and build large-scale, cloud-native data platforms in highly regulated and business-critical environments.
We are currently looking for an experienced Data Cloud Platform Architect to play a key role in the creation and evolution of a complex data platform built from scratch, supporting advanced analytics, governance, and regulatory needs. This is a senior, hands-on architecture role, combining technical leadership, deep cloud data expertise, and close collaboration with engineering, security and business teams.
Key Responsibilities
Design, implement and evolve scalable cloud data architectures, primarily on AWS, aligned with defined data architecture and governance frameworks.
Lead the creation of a cloud-native data platform from the ground up, covering ingestion, processing, storage, and consumption layers.
Define and enforce technical standards, best practices and architectural principles across data engineering initiatives.
Translate business and regulatory requirements into robust technical solutions.
Oversee and contribute to the design of data pipelines and ETL/ELT processes using technologies such as AWS Glue, Lambda, Step Functions and Apache Airflow.
Support the management and optimisation of large-scale datasets using Apache Iceberg and modern lakehouse approaches.
Ensure efficient data integration into analytical and operational stores such as Redshift, Postgre SQL and Duck DB.
Optimise data models and queries for performance, scalability and cost.
Governance, Security & Reliability
Lead the implementation and enforcement of data governance, security and compliance standards across the data platform.
Ensure production readiness through monitoring, logging and tracing mechanisms using services such as Cloud Watch, Cloud Trail and X-Ray.
Proactively identify risks, performance bottlenecks and improvement opportunities.
Technical Leadership
Act as a technical reference and subject matter expert for cloud data architecture and engineering.
Provide guidance and mentorship to data engineers and technical teams.
Challenge requirements when needed and propose innovative, efficient and cost-effective solutions.
Produce and maintain clear solution and technical documentation.
