Data Engineer

We are looking for a
Senior Data Engineer
to join a high-performing data engineering team at a leading global company operating at the intersection of
sports, technology, and digital commerce
.

In this role, you will take ownership of the systems responsible for
ingesting, transforming, validating, and publishing data
across a large-scale data ecosystem. You will work at the data ingestion boundary, where information from multiple internal and external sources enters the platform, ensuring it is accurate, reliable, and ready to power downstream products, analytics, and services.

You will be responsible for building and maintaining
scalable data pipelines
, solving complex
identity and entity-matching challenges
, identifying and addressing data-quality issues, and improving the reliability and observability of data flows across the organization.

This is a highly hands-on engineering role that combines
AWS data engineering, Python, SQL, event-driven architectures, data quality, and identity resolution
. You will work closely with engineering, product, analytics, and downstream platform teams to troubleshoot complex data challenges, improve existing systems, and build reliable solutions that support data-driven products at scale.

What You'll Do

•
Own and evolve data ingestion pipelines
that bring data from multiple external and internal sources into the platform, including ingestion, cleaning, curation, entity resolution, and event-driven publishing.

• Design, build, and maintain
scalable batch and event-driven data workflows
using Python, SQL, and AWS.

• Solve complex
identity resolution, entity matching, and deduplication challenges
across multiple data sources, ensuring reliable and consistent entity mappings.

• Build and maintain
data quality and validation frameworks
, including freshness monitoring, null-rate and consistency checks, and schema-drift detection.

• Monitor data at the ingestion boundary and proactively identify, troubleshoot, and resolve issues before they impact downstream products and services.

• Partner with engineering teams responsible for
event infrastructure and downstream identity services
to trace data and events end-to-end.

• Collaborate with
Product, Assessments, Analytics, and Engineering
teams to understand how data is consumed downstream and ensure pipelines meet evolving product and business requirements.

• Work with AWS services such as
Glue, Athena, S3, and DynamoDB
to build and operate reliable, scalable data infrastructure.

• Automate infrastructure and pipeline changes using
Infrastructure as Code
, primarily Terraform or AWS CDK.

• Participate in
production incident response
, quickly assessing impact, identifying root causes, and implementing effective remediation.

• Continuously improve the
reliability, observability, scalability, and maintainability
of data pipelines and platform infrastructure.

What You'll Bring

•
5+ years of experience
building and operating production-grade data pipelines and data infrastructure.

• Strong experience with both
batch processing and event-driven architectures
.

• Hands-on experience with
AWS Glue, Athena, and S3-based data lakes
, including layered or medallion-style data transformations.

• Strong proficiency in
Python and SQL
for data processing, transformation, and analysis.

• Experience solving
identity resolution, entity matching, and deduplication
problems, including exact and fuzzy matching approaches.

• Understanding of
durable identifiers and identity-mapping strategies
, including the challenges associated with maintaining consistent first-seen or locked mappings over time.

• Experience working with
event schemas and schema-registry-backed contracts
, such as Protobuf, and an understanding of the impact of schema evolution on downstream consumers.

• Strong
troubleshooting and production incident-response skills
, with the ability to assess impact, identify root causes, and drive issues through resolution.

• Ability to understand and debug code written in a
functional or concurrent programming language
, such as Elixir.

• Strong communication and collaboration skills, with the ability to work effectively across engineering, product, analytics, and other technical teams.

Nice to Have

• Experience with
Elixir/Phoenix
or other
BEAM-based concurrent processing frameworks
.

• Experience with
DynamoDB-backed identity, lookup, or matching services
.

• Experience with the
Snowflake ecosystem
, including data modeling, Snowpipe, Streams, and Tasks.

• Experience working with
sports data providers, licensed data providers, or other complex external data ecosystems
.

• Experience implementing
data observability
, including freshness and staleness alerts, null-rate monitoring, schema-drift detection, and data-quality dashboards.

• Experience managing infrastructure through
Terraform or AWS CDK
.
