What you'll do
Personalization (primary focus)

Design and review the systems that power Switchboard, our internal targeting and config layer built on top of Statsig, for personalized slot delivery

Guide transactional email personalization (Knock) architecture for order confirmations, shipment updates, and lifecycle messaging
Set standards for how personalization services work within the WunderGraph federation gateway and JWT sidecar
Partner with Product and the Personalization Lead on technical strategy, and review designs and code across the squad to keep the bar high
Mentor L3/L4 engineers on the team and represent Personalization in cross-squad technical discussions, including with Intelligence
Agentic development
Use AI coding agents (Claude Code, Cursor,
or similar) daily to accelerate feature work, technical design, and code review
Write and maintain agent-readable context files (CLAUDE.md, AGENTS.md) and skills that encode personalization-service conventions so agents produce code that passes review
Define guardrails and scaffolding that keep agent-generated code aligned with our architecture, testing, and data-handling standards
Evaluate agent output quality, iterate on prompts and workflows, and bring a point of view on where agentic tooling fits into the team's day-to-day
Mentor other engineers on the squad in using agentic tooling effectively
Intelligence (cross-squad support)
Pitch in on marketing attribution and enhanced conversion tracking work, primarily dbt models running against Snowflake
Support CDP (Segment) event and trait governance, including schema and model changes in dataengineering-dbt-segment
