Descripción de la vacante

Pleo is seeking a Senior Backend Engineer to join the Data Serving team, owning the boundary between raw product data and consumers including internal dashboards, AI agents, and customers. You will build APIs and a low-latency serving layer with strict data governance and security.

You'll work with a Kotlin-based product backend, Postgres-based read models, and modern data infra on AWS/GCP, Kubernetes, and streaming systems. This role supports remote, hybrid or in-person setups.

Formación

• Strong backend engineering experience building and owning reporting and analytics API services and serving-layer infrastructure.
• A mindset focusing on reliability, latency, and SLOs.
• Experience owning API boundary layers including clean endpoint design, versioning, contract stability, and ensuring downstream consumers are never exposed to raw data sources.
• Strong expertise designing performant read-heavy systems, including relational database optimisation, indexing strategies, materialised views, caching, and API performance tuning.
• Solid database fundamentals (SQL and non-SQL) and strong SQL querying skills, as well as deep expertise in Kafka.
• Deep experience with a JVM-based language (Kotlin).
• AWS or GCP with Kubernetes experience; configuring, deploying and operating containerised apps in a k8s environment.

Responsabilidades

• Build and own the Data API boundary for internal dashboards, customer features, and third-party tools.
• Design and optimise read models, indexes, and caching for low-latency queries.
• Integrate with Kotlin-based product backend services to surface correct data for features.
• Ensure reliability and performance with monitoring, incident response and SLOs.
• Define contracts between ingestion/aggregation and serving DB with clean read patterns.
• Collaborate with Authorization to secure APIs using standard auth protocols.
• Develop a near-real-time data aggregation service across Pleo services.
• Design metadata, lineage, and governance to make the serving layer auditable and trustworthy.
• Own access control with row and column-level data access and audit trails.
