Impact's Data Platform Engineering team is looking for a Data Platform Engineer ready to independently own production pipelines and platform components at TB-scale, delivering data reliably, securely, and cost-effectively as the business grows. You'll design and build scalable batch and streaming pipelines, own the reliability, performance, and SLOs of your domain, and participate fully in on-call as a Tier 2 responder.

You'll work with in the Data Analytics Group (DAG), partnering closely with Analytics Engineers, Data Analysts, Data Scientists, and Data Product Managers, though you won't own dbt models, metric definitions, or reporting. We operate with a platform-as-a-product mindset: the platform is an internal product with clear interfaces, paved roads, and strong developer experience, and success is measured by the productivity of the teams who depend on it.

Our ideal candidate combines solid distributed systems engineering with operational maturity, clear communication, and a habit of mentoring those earlier in their careers. The role reports to the Team Lead, Data Platform Engineering, and is based in Cape Town, hybrid, with two days per week in office.

The platform has strong foundations:
Scala and Spark pipelines processing TB-scale data, dozens of managed data connectors, Airflow on Astronomer for orchestration, a mature dbt transformation layer, and Big Query as the core analytical warehouse. You'll also have room to shape the platform's next chapter: modernising parts of the compute stack, and building out governance frameworks, data contracts, SLOs, observability, cost management, and data quality monitoring within your domain.

• End-to-end domain ownership:
  Own platform components and a pipeline domain end-to-end, including design, implementation, reliability, performance, and cost.
• Design and build scalable ETL/ELT and streaming pipelines using Spark/Dataproc, Kafka, and Pub/Sub.
• Integrate diverse sources into Big Query and other stores.
• Build modular, fault-tolerant components with graceful schema evolution.
• Infrastructure & performance tuning:
  Configure and maintain core platform infrastructure as code, including Dataproc, Kafka, Airflow/Astronomer, Big Query, and Cloud Storage.
• Tune performance and cost through query optimisation, partitioning, and resource configuration.
• Tune streaming configurations for throughput and reliability.
• Reliability & incident response:
  Own and track SLOs for freshness, success, and latency.
• Implement monitoring, alerting, and data quality checks.
• Participate in on-call as a Tier 2 responder, troubleshooting and resolving incidents independently.
• Security, governance & self-service:
  Implement security and governance by design, including access control, secrets, encryption, audit logging, lineage, and retention.
• Build self-service…
