About the role

We are looking for a freelance Data Engineer focused on data integration to build and maintain the pipelines that connect our many source systems into a unified, trustworthy data foundation. You will design ETL/ELT processes, integrate APIs and third-party platforms, model data for reporting, and ensure data quality across the organization. This is a fully remote role working closely with analytics, finance, and engineering stakeholders.

Key Responsibilities

• Design, build, and maintain scalable ETL/ELT pipelines that move and transform data between systems.

• Integrate data from diverse sources — APIs, databases, SaaS platforms, flat files, and spreadsheets — into a central warehouse.

• Develop and maintain connectors and reconciliation logic across business systems (e.g., project management, time-tracking, finance, and invoicing tools).

• Model and structure data for analytics, reporting, and downstream applications.

• Implement data validation, quality checks, monitoring, and alerting to ensure accuracy and reliability.

• Optimize queries, storage, and pipeline performance for cost and speed.

• Document data flows, schemas, mappings, and transformation logic.

• Collaborate with analysts, finance, and engineering teams to understand requirements and deliver clean, usable datasets.

• Support data governance, security, and privacy best practices.

Required Qualifications

• 3+ years of experience in data engineering, data integration, or a closely related role.

• SQL: strong SQL skills and experience with relational databases (PostgreSQL, MySQL, SQL Server).

• Programming: proficiency in Python (or a comparable language) for data processing and automation.

• Pipelines: hands-on experience building ETL/ELT workflows and orchestration (e.g., n8n, or similar).

• Integration: experience integrating REST APIs, webhooks, and third-party SaaS data sources.

• Experience with data warehouses (BigQuery, Snowflake, or similar).

• Understanding of data modeling, warehousing concepts, and data quality practices.

• Comfort working with messy, real-world data across formats (CSV, Excel, JSON, XML).

• Strong problem-solving skills and clear communication in a remote team.

Nice to Have

• Experience with cloud data platforms (AWS, or Azure).

• Exposure to finance or operational data and cross-system reconciliation.

• Experience with BI/visualization tools (Looker, Power BI, Tableau).

• Experience in an agency or multi-entity, multi-currency environment.

What We Offer

• Fully remote working with flexible hours.

• A collaborative team spanning engineering, analytics, and finance.

• Competitive salary and benefits package.
