Job Title: Data
Engineer II / AWS Data Engineer
Location: Miami, Florida or Irving, Texas (Hybrid)
Duration: Contract to Hire
Manager: Finance and land domain Analytics
engineer in practice
What the
person will do. Own transformation and modeling work across finance and land
initiatives. The team is rebuilding the client's financial reporting data stack
and preparing consolidated data assets for internal agentic and MCP-based
access.
Day-to-day
split. Approximately 80% dbt/transformation and data-modeling work and 20%
collaboration with business stakeholders. This is not a ticket-taking role; someone
who can receive a project, think critically, and run with it.
Must Haves
- Strong dbt development using SQL and
Jinja.
- Strong SQL and Python fundamentals.
- Snowflake experience and an understanding
of how modeled data supports reusable data products.
- Data modeling and semantic-model
experience, not merely extraction and loading.
- Critical thinking, adaptability, project
ownership, and comfort working directly with stakeholders.
Helpful but
Flexible
- AWS Glue and AWS data-lake experience.
Azure is acceptable if the candidate understands data-flow and lake
concepts.
- Finance, accounting, cash, P&L, or
land-data experience shortens the learning curve.
- Iceberg and experience exposing or
loading transformed data into Snowflake.
- Power BI awareness, although Rob is
intentionally moving away from producing many custom reports.
- Interest in agentic data products and MCP
servers.
Reject or
Probe Carefully
- Traditional ETL engineers who are strong
in ingestion but light on dbt, dimensional/semantic modeling, or business
context.
- BI-only candidates whose main strength is
Power BI report development.
- Candidates who depend on scripted or
AI-fed interview answers and cannot reason through a new scenario.
Your Responsibilities on the Team
- Design,
implement, and support an analytical data infrastructure and working
knowledge of Modern Data Warehouse concepts.
- Design,
build, and maintain efficient and scalable data pipelines and ETL
processes to process large volumes of structured and unstructured data.
- Optimize
data storage and retrieval methods to ensure performance, scalability, and
cost-efficiency.
- Manage
AWS resources including EC2, S3, Glue, Lambda, API’s, IAM, CloudWatch,
etc.
- Interface
with other technology teams to extract, transform, and load data from a
wide variety of data sources using SQL and AWS big data technologies
- Explore
and learn the latest AWS technologies to provide new capabilities and
increase efficiency
- Collaborate
with Data Scientists and Business Intelligence Engineers (BIEs) to
recognize and help adopt best practices in reporting and analysis
- Help
continually improve ongoing reporting and analysis processes, automating
or simplifying self-service support for customers
- Maintain
internal reporting platforms/tools, including troubleshooting and
development. Interact with internal users to establish and clarify
requirements in order to develop report specifications.
- Work
with Engineering partners to help shape and implement the development of
BI infrastructure including Data Warehousing, reporting and analytics
platforms.
- Contribute
to the development of the BI tools, skills, culture, and impact.
- Write
advanced SQL queries and Python code to develop solutions.
- Working
Knowledge of Snowflake.
- Collaborate
across teams to align AI initiatives with organizational goals and an understanding
of AI concepts
- Knowledge of
continuous integration/continuous delivery (CI/CD) pipelines and working
on deployments when necessary.
Requirements
- Bachelor's degree in Computer Science,
Information Technology, or a related field.
- 3-5 years of experience in data engineering or a
related role, with demonstrated success in delivering data solutions.
- AWS Glue, Lambda, S3, EC2, CloudWatch, Cloud
Trail.
- Dbt, Snowflake, SQL, Python, Qlik.
- Proficient in SQL, with the ability to write
complex queries, perform query optimization, and conduct performance
tuning.
- Experience with NoSQL databases, such as
MongoDB, Cassandra, or DynamoDB, and an understanding of their appropriate
use cases.
- Strong programming skills in Python, Java, or
Scala, with experience in data processing frameworks (e.g., Apache Spark,
Hadoop).
- Experience with cloud platforms (AWS, Azure, GCP)
and data services, such as AWS Redshift, Azure Synapse, or Google
BigQuery.
- Knowledge of big data technologies, including
Hadoop, Spark, Kafka, and HBase, with experience in distributed data
processing.
- Familiarity with data orchestration tools, such
as Apache Airflow for scheduling and managing data workflows.
- Experience with data versioning and testing
tools, such as DVC (Data Version Control) and dbt (data build tool).
- Understanding of data security practices,
including encryption, access controls, and data masking.
