Senior Lead Software Engineer, Full Stack (Enterprise Platforms Technology)
Within EPTech, you'll join the Unified Customer Graph team–building the enterprise's authoritative system of record for customer identity: every human, business, account, device, and the relationships linking them. This is a graph-native platform serving entities and relationships at scale with low latency. You'll work at the intersection of distributed systems, graph data modeling, and access control.
This is a senior lead IC role where you'll be expected to lead architecture decisions, drive proof-of-concepts from ideation to production readiness, and influence platform direction across organizational boundaries.
What You’ll Do:
Design and build API layers that enforce access control semantics, ensuring consumers only receive data they're authorized to access
Lead architecture proofs-of-concept that resolve open technical questions — then drive findings into production-ready decisions
Own technical workstreams end-to-end: scope definition, interface contracts, implementation, and operational readiness
Operate in an AI-augmented engineering model: design the tools, quality gates, and validation patterns that accelerate delivery
Design graph data models that represent complex entity relationships at enterprise scale
Collaborate across organizational boundaries with architecture, product, and data engineering counterparts
Drive infrastructure and topology decisions backed by performance data, not assumptions
Define and validate non-functional requirements (latency, throughput, availability) rooted in documented business needs
Basic Qualifications:
