Senior Data Engineer

At Aajil (formerly Buildnow), we're powering smarter decisions for B2B commerce through data-driven credit solutions. As a
Senior Data Engineer
(Remote), you'll build and scale the data infrastructure that fuels our underwriting models, analytics dashboards, and real-time decision engines. If you have serious technical chops, love designing robust systems at scale, and thrive in collaborative environments, this is your opportunity to do some of the most challenging data engineering work in fintech.

What You'll Do

You'll tackle complex data engineering challenges and build production systems that process high-volume transactional data. Your responsibilities include:

• Building and scaling data infrastructure
  that processes millions in transaction volume and powers real-time credit decisions.
• Designing and implementing data pipelines
  across data lakehouses, OLAP systems, and event-driven architectures using GCP or AWS.
• Optimizing ETL/ELT workflows
  with tools like dbt, Airflow, Spark, and Kafka to ensure data reliability and performance at scale.
• Implementing real-time data processing
  and streaming analytics that support instant underwriting decisions.
• Productionizing ML models
  in collaboration with data scientists, ensuring models run efficiently in production.
• Contributing to technical strategy
  for data architecture, tooling decisions, and infrastructure improvements.
• Collaborating closely
  with engineering leadership, Risk, Product, and Analytics teams to solve complex data challenges.
• Writing production-grade code
  with strong Python fundamentals, clean architecture, and robust testing.
• Ensuring data quality, governance, and security
  across all systems and pipelines.

What We're Looking For

We need someone with
serious technical depth
who can hit the ground running and tackle our hardest data problems. The ideal candidate will have:

• 5+ years of experience in data engineering
  with a proven track record of building and scaling production data systems in high-growth environments.
• Deep expertise in cloud platforms
  (GCP/AWS) and modern data tools (dbt, Airflow, Spark, Kafka, BigQuery/Redshift).
• Strong programming fundamentals in Python
  , with solid understanding of data structures, algorithms, and software engineering best practices.
• Hands-on experience with diverse data architectures
  , including data lakehouses (Delta Lake, Iceberg), OLAP systems, and event-driven pipelines.
• Proven ability to design and optimize for scale
  , tackling performance, cost, and reliability challenges in high-throughput environments.
• Experience productionizing ML models
  and working closely with data science teams.
• Strong problem-solving skills
  and ability to troubleshoot complex issues across distributed systems.
• Excellent collaboration skills
  and ability to work effectively with both technical and non-technical stakeholders.
• Track record of shipping complex projects
  from design to production.

Nice-to-Have:

• Experience in fintech, lending, or credit risk environments.
• Familiarity with data governance and compliance frameworks.
• Contributions to open-source data tools or active involvement in the data engineering community.
• Experience with real-time fraud detection or underwriting systems.
