Senior Data Engineer

Role summary 

We’re looking for a Senior Data Engineer with a drive for excellence and an ownership mindset who can lead the design and delivery of scalable, secure, and highly reliable data platforms in a complex payments and fintech environment. You set the technical bar for your team: you architect systems, make sound trade-off decisions, unblock cross-team delivery, and mentor engineers. 

You’re deliberate about how AI-assisted development is adopted on your team, setting guardrails that prevent shortcuts from becoming long-term cognitive debt, while actively using AI to solve real engineering and business problems. 

AI-first mindset: We value engineers who can incorporate AI and agentic development practices into how we build data systems, setting patterns for responsible AI-assisted engineering across design reviews, code quality, testing, and documentation, while delivering data engineering-led AI use cases such as intelligent data quality and observability, anomaly detection, automated alert triage, and governance. 

What You’ll Do 

• Own the technical architecture for large-scale batch and streaming data pipelines that power product, risk, and reporting use cases, using frameworks such as Apache Beam, Spark, or Flink with managed runners like Google Cloud Dataflow. 

• Lead data warehouse and lakehouse design for analytical and operational usecases, setting modelling standards and driving performance and cost optimisation. 

• Design event-driven and streaming architectures with strong correctness guarantees schema evolution, replay and backfill strategies, late-data handling, idempotency, and operational safety. 

• Build and operate storage patterns for operational and analytical workloads using wide-column stores (Bigtable, Cassandra, HBase, or equivalents), including capacity planning and SLO definition. 

• Establish orchestration and operational excellence using tools like Airflow, Composer, Dagster, or Prefect - including CI/CD strategy, automated testing, pipeline observability, and incident response practices. 

• Drive data quality, governance, and auditability through automated controls, lineage/metadata practices, and secure-by-default access patterns. 

• Lead through technical influence: mentor engineers, run design reviews, maintain decision records, unblock cross-team delivery, and shape roadmaps through clear technical reasoning. 

• Set the standard for how your team uses AI-assisted development, ensuring AI-generated code meets the same review, testing, and documentation bar as any other code. Identify and deliver AI-driven solutions for data engineering problems such as intelligent data profiling, anomaly detection, and automated root-cause analysis, with a focus on reproducibility and governance. 

Who You Are 

• You are a seasoned data engineer with a strong sense of ownership and accountability, comfortable operating in complex domains and driving end-to-end delivery from design through production operations. 

• You balance long-term platform thinking with pragmatic execution, and you know how to raise reliability and quality without slowing teams down. 

• You thrive in cross-team environments and influence through technical leadership, clarity, and strong execution. 

• You are impact-driven and measure success by how effectively you enable teams, improve data trust, and accelerate product outcomes. 

• You think critically about AI adoption in engineering workflows, you see the leverage it provides, but you also understand the risks of unchecked reliance: reduced understanding, hidden errors, and maintenance burden. You set patterns that capture the upside while protecting quality. 

Key skills and competencies 

• Strong track record delivering production-grade data pipelines and datasets end-to-end: design, implementation, deployment, and operations. 

• Deep experience with distributed data processing 

• Expertise with cloud data warehouses (BigQuery, Snowflake, Redshift, or Databricks) including strong dimensional modelling, query optimisation, and cost management skills. 

• Hands-on experience designing systems on event streaming platforms including schema management, delivery semantics trade-offs, and operational patterns like replay and backfill. 

• Experience with operational and wide-column stores (Bigtable, Cassandra, HBase, or equivalents) with a strong understanding of access-pattern-driven design and capacity planning. 

• Strong orchestration and platform engineering experience with Airflow, Dagster, or Prefect, including CI/CD, automated testing, observability, and incident response. 

• Demonstrated technical leadership: mentoring, design reviews, architectural decision records, and the ability to influence stakeholders and align teams around technical direction. 

• A considered approach to AI-assisted engineering: you use AI tools to improve throughput and quality, but you also set guardrails, review standards, testing expectations, documentation requirements. 

Preferred 

• Prior experience in fintech, payments, lending, or broader financial services (e.g., reconciliation, settlement, risk and fraud data, regulatory reporting). 

• Experience operating data systems with defined SLOs/SLAs and governance in cloud environments. 

• Familiarity with data governance and compliance standards: PII handling, access controls, auditing, and policy-as-code patterns. 

• Experience partnering with ML/DS teams to productionise features, training datasets, and monitoring infrastructure.
