AI Engineer, Data Infra

Data infrastructure and architecture

• Develop and maintain the overall data architecture, ensuring it scales to support AI training, fine-tuning, evaluation, and RAG workloads.
• Define and manage the data technology stack, evaluating and adopting tools that best fit evolving data needs.
• Build automation for data transfer and backup, and support data cataloging/discovery tools.
• Design and maintain data pipelines (batch and streaming) using tools like AWS Glue and Amazon EMR.

Data governance and management

• Architect and govern org-level IAM policy across AWS Organizations including SCPs, cross-account roles, and permission boundaries to enforce least-privilege access at scale.
• Review and enhance data access patterns for performance and cost optimization.
• Develop and manage data analytics and dashboarding capabilities using tools like Amazon Athena and QuickSight to give stakeholders visibility into platform usage and cost.

AI-assisted ops and continuous improvement

• Use AI tools (e.g. Claude, Copilot, Cursor) appropriately in your daily work responsibilities.
• Build internal tools leveraging AI to reduce manual effort in day-to-day operations.

You should be a hands-on engineer who enjoys both building robust infrastructure and designing tools that other engineers and researchers want to use. You should be comfortable balancing platform ownership (architecture, cost, governance) with product thinking (usability, self-service, adoption).

• A degree in Computer Science, Information Technology, or equivalent.
• At least 2-4 years of data infrastructure, platform or systems engineering experience, with a track record of operating production systems at scale.
• Strong knowledge of distributed data systems and storage technologies (object storage, data lakes, distributed file systems, vector databases) and data pipelining tools (e.g. Apache Spark, Apache Airflow, Ray, Dagster).
• Working knowledge of data access control and data orchestration.
• Familiarity with cloud organisational structures (e.g. AWS Organizations, GCP folder/project hierarchy), including multi-account/multi-project setups, org-level IAM, and billing/cost allocation.
• Hands-on experience operating workloads on different cloud providers including IaC (e.g. Terraform), containers and orchestration (e.g. Docker, Kubernetes), and managed services for compute, storage, and networking.
• Demonstrated use of AI tools (e.g. Claude, Copilot, Cursor) in your day-to-day engineering - for code generation, review, debugging, and documentation - with a clear sense of where they help and where they don't.
• Solid scripting/programming skills (e.g. Python, SQL) and comfortable reading other people's code across the stack.
• Strong communication skills and a team collaborator.

• Experience with LLM training dataset (e.g. Common Crawl).
• C/C++/Rust/Go or other relevant programming languages.
• Contributions to open-source AI/ML projects.
