Senior Software Engineer (Identity)

• We are looking for a Staff Software Engineer to join our Identity team in Amsterdam. The Identity team builds and operates the core systems that power Samba TV’s cross-device identity resolution, data onboarding, and distribution capabilities, the foundational layer connecting data to advertisers, agencies, data partners, and internal product teams
• You will architect and deliver large-scale, cloud-native data engineering systems that ingest, transform, and distribute identity-linked data at scale
• You bring 12+ years of experience and operate as a technical authority, setting direction, resolving complex ambiguity, and shaping how Identity systems evolve to support Samba’s expanding product ecosystem
• You are a subject matter expert recognized across the organization, drive cross-functional alignment, and are accountable for outcomes that span the Identity domain and broader product engineering
• Design, build, and operate large-scale data pipelines for ingestion, transformation, and distribution of identity-linked data, setting the standard for reliability, accuracy, and extensibility across the domain
• Architect ETL/ELT workflows using distributed computing frameworks on cloud infrastructure, making and owning the key engineering decisions that shape how the team builds and scales
• Design and build API-first, platform-grade services that expose Identity capabilities as self-service building blocks, with clear contracts, strong reliability, and ease of integration for internal teams and external clients
• Define and implement observability, data quality validation, and monitoring frameworks to ensure pipeline health at scale
• Drive performance optimization, cloud cost efficiency, and platform-thinking across Identity’s systems, ensuring components are reusable and enable downstream teams to build with confidence
• Own the technical evolution of Identity’s core systems, including probabilistic and deterministic matching, device graph construction, and audience segmentation — driving their reliability, scalability, and long-term direction
• Architect and implement secure data collaboration capabilities, including clean room workflows and privacy-preserving computation, embedding privacy-by-design across all system development with deep application of GDPR, CCPA, and Samba’s data governance policies
• Set the technical direction for how Identity systems serve all downstream use cases, engaging product, data science, commercial, and partner stakeholders to ensure alignment and fit for purpose
• Own technical design and architecture for Identity systems producing clear, decision-driven design documents, contributing to org-level architectural discussions, and driving alignment across engineering, product, and commercial stakeholders
• Lead code and design reviews, champion high standards for code quality, testability, and maintainability, and drive formal alignment across teams on shared tooling and patterns
• Mentor and invest in the growth of engineers across the Identity team through structured feedback, pairing, and design reviews, raising the bar for the team as a whole
• Partner with the Engineering Manager and cross-functional leads on roadmap shaping, technical planning, and systemic risk resolution
• Own the end-to-end reliability of Identity systems, lead incident response, drive post-mortem actions to closure, and deliver sustained improvements to system health
• Define, monitor, and continuously improve SLAs, SLOs, and operational metrics for Identity pipelines and services
• Drive maturity in CI/CD, deployment practices, and testing coverage across the team’s systems
