This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Staff Software Engineer - Curated Data based in Spain.

As a Staff Software Engineer, you will help design the systems that power high-quality, trusted datasets across a rapidly evolving onchain data environment.
You will own challenging problems around data orchestration, dependency management, schema evolution, corrections, and recovery at significant scale.
The role combines deep backend engineering with data systems expertise, requiring strong architectural thinking and a focus on reliable software contracts.
You will take ambiguous product requirements, turn them into clear technical designs and execution plans, and personally build the most complex components.
Working across multiple programming languages and technologies, you will choose the right solution based on the problem rather than familiarity.
You will also help distributed engineering teams break down complex initiatives, ship incrementally, and maintain high engineering standards.




This is an opportunity to have substantial technical influence while working on foundational systems where data quality and correctness are critical.

Accountabilities

-
Design and build the control plane for the curated data lifecycle, including dependency-aware orchestration, backfills, restatements, retries, partial-failure handling, and recovery mechanisms.

-
Own architectural decisions across datasets, determining when a problem is best addressed through a data model, service, or job.

-
Design and maintain clear contracts between data ingestion and curation layers so datasets can be understood and managed end to end.

-
Build reliable alerting, monitoring, and data-quality signals that identify genuine issues while minimising operational noise.

-
Work across Go, Kotlin, Rust, Python, and SQL, selecting technologies based on the requirements of each problem.

-
Develop software that orch
