Senior Software Engineer, Identity & Regulatory Platform

As a Senior Software Engineer on the Identity & Regulatory Platform team at Paxos, you'll build the AI-enabled trust layer that lets the world's largest financial institutions adopt blockchain safely. You own the customer journey from first contact through onboarding to activation, designing systems that verify and onboard customers, using AI to automate compliance review, and measuring every step of the funnel. You work directly with Product, Compliance and identity vendors, shaping how fast customers go live and how well Paxos meets its regulatory obligations.

What you'll do

• Own the customer journey from lead to onboarding to activation, across the Paxos Dashboard and Identity APIs
• Instrument the onboarding funnel, find drop-off and friction, and run experiments that cut time-to-activation
• Design, build and operate backend services for KYC/KYB, identity verification, screening and identity lifecycle
• Use AI to automate compliance work such as document review, case triage and risk assessment, replacing manual ops
• Own integrations with third-party identity and screening vendors, including async workflows and webhooks
• Build data-privacy capabilities (GDPR erasure, PII handling) into the platform from the start
• Write design docs, lead technical decisions, mentor teammates and take part in on-call

What you bring

• 5+ years building production backend systems, with 1+ year at senior level
• Strong experience in Go, Java or Python (Go strongly preferred)
• Experience designing APIs and data models for sensitive or regulated data
• A focus on outcomes such as conversion, activation and time-to-value, not only shipping features
• Comfort turning ambiguous requirements from non-engineering stakeholders into clear technical plans
• Daily use of AI tools to work faster and better

Nice to have

• Experience with identity, KYC/AML or onboarding systems
• Background in growth engineering or experimentation
• Experience building LLM features into production
• Familiarity with Persona or similar identity vendors
