Senior Data Engineer

About the role

We are looking for a Senior Data Engineer to replace a third-party data ingestion tool with an owned ETL pipeline.

The mandatory requirements are 4+ years of experience with SQL and ETL pipelines, hands-on experience with AWS, direct experience with MCP or with AI agents and Claude Code, and an upper-intermediate English level.

Must haves

• 4+ years of strong SQL and large-scale data ingestion/pipeline experience (batch ETL, orchestration, schema design).
• Working knowledge of AWS data services (RDS/Postgres, S3, ECS) sufficient to build within an existing cloud environment.
• Practical experience with Claude Code or similar tools , and agents or MCP in real work.
• Ability to contribute to application and backend work beyond pure ETL to support broader platform needs.
• Familiarity with, or ability to quickly evaluate, managed ELT tools (such as Fivetran) against custom builds.
• Ability to ramp into existing attribution and scoring logic so ingestion output aligns with downstream dashboard needs.
• Upper-intermediate English level.

Nice to haves

• Direct or adjacent experience with digital advertising / DSP data (e.g., Amazon DSP, Amazon Advertising API, or comparable programmatic platforms).
• Experience replacing legacy third-party data pipelines with owned, custom infrastructure.
• Familiarity with MLOps pipelines and how data feeds predictive models.
• Experience working alongside part-time technical advisory leads to validate architecture decisions.

What you will do

• Document current ingestion logic inside the legacy tool (TapClicks), including sources, endpoints, schemas, and transformation logic.
• Build the ETL pipeline to replace the legacy system, handling ingestion from the Amazon API, other DSP platforms, and related digital data sources.
• Evaluate and decide between off-the-shelf solutions (e.g., Fivetran) and owned ETL systems alongside the Infrastructure Lead.
• Design the pipeline as a standalone, owned system to power Diray's client-facing dashboards.
• Provide flexible engineering support for MAT and the Impact Engine application and backend work within the AWS environment when directed.
• Coordinate with data science teams to ensure ingestion output aligns with the attribution and scoring logic of downstream models.
• Work seamlessly within the existing AWS environment (ECS, S3, RDS) rather than standing up parallel infrastructure.

Perks

• Growth without limits: build your skills through mentorship, internal TechTalks, challenging projects, and a dedicated annual learning budget
• Competitive compensation: get recognition that reflects your skills and impact, with regular performance and compensation reviews
• Flexibility: work 100% remotely with flexible hours that support focus, autonomy, and a healthy work rhythm
• Meaningful, modern projects: build impactful products using modern technologies alongside global teams and leading brands
• Collaborative culture: join a supportive environment with zero micromanagement where ideas are welcomed and contributions are recognized
• Well-being & support: access local well-being programs and people-focused support tailored to your location
