Ryz Labs is looking for a Principal Data Engineer who can design, build, and own modern data platforms end-to-end: from ingestion pipelines and cloud infrastructure through to high-quality, production-grade code. You’ll pair traditional data-engineering strengths with solid software-development practices to deliver resilient data products that scale. This role is perfect for someone who thrives in high-pressure environments, values straight talk, and takes deep pride in craftsmanship, even when requirements are ambiguous.

Key Responsibilities

• Design & build pipelines – Develop, test, and maintain robust batch and streaming data pipelines in Python, SQL, and Spark/Databricks.

• Engineer infrastructure – Provision and evolve cloud resources (AWS, Azure, or GCP) via IaC

frameworks such as Terraform or CloudFormation.

• Apply software-craft disciplines – Enforce version control, automated testing, CI/CD, and code

reviews; write clean, idiomatic, well-documented Python.

• Author design artefacts – Produce clear architectural diagrams, ADRs, and technical design

documents that guide implementation and onboarding.

• Monitor & optimize – Instrument pipelines, build dashboards, and tune performance; own incident response and root-cause analysis.

• Champion data quality & governance – Implement validation, lineage, and observability to guarantee trustworthy data assets.

• Collaborate cross-functionally – Partner with product, data science, and platform teams to translate business questions into scalable data solutions.

Required Skills & Qualifications

Certifications

• Databricks certified data engineers

• Cloud specific data engineering certifications

Technical Expertise

• Python mastery – OOP, type hints, packaging, and performance tuning.

• Spark mastery - Performance tuning and data engineering optimizations

• SQL mastery - Expert SQL and data-model design for relational databases.

• Infrastructure-as-Code (Terraform, CDK, or ARM) and CI/CD tooling (GitHub Actions, Jenkins, Azure DevOps).

• Knowledge of observability/monitoring (Datadog, Prometheus, OpenTelemetry) for data services.

• Well-versed in the setup of data quality and data integrity pipelines

• Comfortable with writing design documents
