About The Position

We are seeking a Staff Software Engineer to join Reference and Entity Data Systems (REDS) and own the design and evolution of our entity data platform — ingesting company data from global vendors, resolving it into authoritative records, and delivering accurate, timely data to downstream teams and customers. REDS owns vendor ingestion, entity generation, data quality and freshness, and delivery to downstream consumers. If entity data is wrong, incomplete, or stale, everything downstream fails. Human validation still acts as a safety net in parts of the pipeline. Your mission is to systematically reduce that dependency by increasing correctness, confidence, and trust — without sacrificing speed or scale. You will operate at the intersection of distributed systems, entity resolution, data quality, AI-assisted decision-making, and platform architecture.

Requirements

8+ years building and operating large-scale production systems
Proven experience with data ingestion, entity resolution, matching, or normalization at scale
Deep expertise in one or more of: distributed systems, data pipelines, reference data platforms, platform engineering, or AI-powered classification and validation
Strong code, system design, and architecture pattern skills
Ability to design trustworthy systems combining probabilistic (AI) and deterministic approaches
Delivery excellence: incident response, observability, and reliability improvements that stick
Effective use of AI, testing, automation, and tooling to ship confidently
Track record of setting standards, driving technical decisions, and elevating peers through documentation and mentoring
End-to-end ownership from integration through entity generation to operational readiness

Nice To Haves

Experience with company or financial reference data, or vendor reconciliation
Provenance, lineage, confidence-scoring, or quarantine/resolution workflows
Integrating new data vendors end to end
Cloud-native architectures and internal platforms shared across teams

Responsibilities

Own the architecture and evolution of a major area of the entity data platform
Design systems that process large volumes of heterogeneous vendor data with high reliability, freshness, and accuracy
Reduce manual validation overhead through AI-assisted resolution, confidence scoring, provenance, and deterministic matching rules
Establish clear contracts for correctness and traceability — e.g., which source supplied a field, why an entity was matched or created
Balance AI-driven and rules-based approaches where each improves reliability and explainability
Deliver end-to-end integrations across ingestion, matching, entity generation, and delivery
Respond to production incidents in your area; improve observability and reliability through iterative hardening
Set engineering standards, mentor engineers, and partner with product and downstream consumers on quality bars and success metrics
