AlphaSense is seeking a Staff Software Engineer to join the Reference and Entity Data Systems (REDS) team. You will own the design and evolution of the entity data platform, which ingests company data from global vendors, resolves it into authoritative records, and delivers accurate, timely data to downstream teams and customers.
The REDS platform is mission-critical: it handles vendor ingestion, entity generation, data quality and freshness, and delivery to downstream consumers. If entity data is wrong, incomplete, or stale, everything downstream fails. Your mission is to systematically reduce manual validation overhead 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. Key responsibilities include:
- Own the architecture and evolution of a major area of the entity data platform
- Design systems that ingest and serve large volumes of heterogeneous vendor data at scale 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; 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
AlphaSense is a market intelligence platform trusted by over 6,000 enterprise customers, including a majority of the S&P 500. Founded in 2011, the company is headquartered in New York City with 2,000+ employees across offices in the U.S., U.K., Finland, India, Singapore, Canada, and Ireland.
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
- Experience evolving or re-platforming live systems with many downstream consumers
PREFERRED:
- 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
