The Role:

Eckoh is building a new Data Lakehouse on Databricks and AWS to underpin real-time client dashboards, operational reporting, AI and data science capabilities, and compliance data management across multiple regions.

As Principal Data Engineer, you are the most senior engineer on the team. Working closely with the Team Lead, you will help shape the architecture, contribute to engineering standards, and work on the most demanding parts of the system, guiding the team where needed. This is a role with real technical depth and influence over a greenfield platform, but one that operates within a shared technical direction set collaboratively.

During the initial build phase, an external delivery partner will be embedded within the team. You will work alongside their engineers, providing technical direction, setting shared standards, and ensuring the architecture and engineering practices being established are ones Eckoh will be able to own and build on confidently after handover.

Your work will span the full depth of the platform, from ingestion and pipeline design through to the data products that serve client dashboards, operational reporting, and AI use cases.

Key Functional Responsibilities:

Architecture:

• Contribute to the definition of the end-to-end architecture of the Data Lakehouse, covering ingestion, storage, processing, and serving layers, and the integration patterns connecting source systems to downstream consumers.
• Play an active role in establishing the target-state architecture from a greenfield position, contributing to foundational decisions on data modelling approach, medallion layering, batch vs streaming, and multi-region design, and helping to document rationale and trade-offs.
• Work with the Team Lead to uphold architectural standards, patterns, and reference implementations that both the internal team and the delivery partner build against

Engineering:

• Build pipelines, integration patterns, and platform components. This is a hands-on role and the Principal is part of delivery, not just directing it.
• Work with the Team Lead to define and uphold engineering standards across the team, covering code quality, testing, documentation, code review, and deployment practices.
• Contribute to and champion the CI/CD and infrastructure-as-code practices that underpin reliable, repeatable platform delivery.
• Act as a senior technical escalation point for production data issues, pipeline failures, and platform incidents post-handover.

Data:

• Define gold-layer datasets, semantic models, and data contracts that power client dashboards, operational reporting, billing assurance, and AI analytics.
• Work closely with the analytics engineering and BI development functions to ensure modelling and Tableau patterns are consistent, performant, and maintainable.
• Ensure reporting data products meet the accuracy, latency, and availability expectations of client-facing and internal consumers.

Delivery:

• Contribute to sprint planning, estimation, and prioritisation alongside the Team Lead and Technical Product Owner, bringing engineering depth to delivery decisions.
• Identify and surface technical risk early, propose mitigation approaches, and help the team maintain momentum without accumulating avoidable technical debt.
• Support and mentor senior and mid-level engineers, helping them grow their technical capability and raise the overall standard of engineering across the team.

Partner & Stakeholder Management:

• During the initial build phase, work alongside the delivery partner on architecture alignment, code review, and knowledge transfer, ensuring a smooth transition to Eckoh ownership.
• Engage with Databricks on platform capabilities, roadmap, and technical support as usage scales.
• Communicate technical decisions and trade-offs clearly to non-technical stakeholders, including the Head of Product and commercial teams.

Data Governance & Quality

• Embed governance into the platform from day one, covering data classification, access control, lineage, cataloguing, retention, and deletion across all data domains.
• Set and maintain data quality standards, ensuring pipelines deliver accurate, complete, and timely data to all downstream consumers.
• Ensure sensitive data, including payment and personal data, is handled appropriately throughout ingestion, processing, storage, and consumption.
• Ensure the platform meets data sovereignty, PCI DSS, SOC2, and GDPR obligations across all regions in which Eckoh operates.

Platform Operations & Cost

• Define SLAs for data products and pipelines. Drive reliability, performance, and cost efficiency across the platform.
• Monitor cloud and Databricks spend, identify optimisation opportunities, and ensure the platform operates within a responsible run rate without compromising quality or reliability.
• Partner with DevOps and Cloud Ops teams on deployment pipelines, observability tooling, and the rollout of additional data processing regions.

Essential Skills & Experience

• Demonstrable hands-on data engineering background, with significant experience designing and operating cloud-native data platforms in production.
• Deep, hands-on experience with Databricks, including Spark and PySpark, Delta Lake, Unity Catalog, and medallion architecture, with at least one deployment of meaningful scale.
• Strong proficiency in Python and SQL, used in production data engineering contexts.
• Strong AWS data stack knowledge, including S3, IAM, and networking, with sufficient familiarity with Glue, EMR, or Athena to make informed build-vs-buy decisions alongside Databricks.
• Experience designing systems that serve both low-latency operational queries and large-scale analytical workloads from a shared lakehouse foundation.
• Strong grounding in data modelling, including medallion architecture, dimensional modelling, data contracts, schema versioning, and serving layer design.
• Experience with infrastructure-as-code and CI/CD for data pipelines, using tools such as Terraform, GitHub Actions, or equivalent.
• Experience implementing data observability, covering data quality, lineage, freshness, and pipeline health monitoring.
• Familiarity with data governance concepts as implemented in modern Lakehouse platforms, covering cataloguing, lineage, classification, and access control.
• Comfortable operating in a regulated environment with PCI DSS, GDPR, SOC2, or similar compliance obligations.
• Demonstrated senior individual contributor leadership, with the credibility and communication skills to set technical direction for engineers and partners alike.

Desirable Skills & Experience

• Hands-on experience with Databricks Unity Catalog, Delta Live Tables, or Databricks Workflows.
• Experience with real-time or streaming data pipelines, using tools such as AWS Kinesis, Apache Kafka, or Databricks Structured Streaming.
• Experience working alongside a systems integrator or delivery partner on a build-and-handover engagement.
• Familiarity with Tableau or similar BI and embedded analytics tools, particularly from a data platform and serving layer perspective.
• Exposure to payments, contact centre, conversational AI, or SaaS platform domains.
• AWS or Databricks certifications.
