We're looking for a Principal Data Engineer to be the most senior individual contributor on the Data Platform Engineering (DPE) team at Hims & Hers. In this role, you will define and align the architectural vision for our data platform with business goals – working in close partnership with product, engineering, and data science leadership. Your scope is org-wide: you will set technical direction across every surface DPE owns, drive the highest-stakes architectural decisions, and establish the standards that the entire data engineering discipline operates by.

Our platform serves millions of patients across telehealth, prescription, and wellness products. It runs on GCP Big Query, Airflow on Astronomer/EKS, dbt, Confluent Kafka, Databricks Delta Lake, and Terraform/Open Tofu – and it is in active, consequential evolution: a net-new streaming platform, and a lower environments strategy being built from scratch. You will own those architectural bets.

• Own the long-term technical architecture for DPE across ingestion, orchestration, event streaming, and the platform infrastructure that enables transformation and serving - driving the highest-stakes decisions for the CDC-based streaming platform (Kafka → Flink → Big Query), orchestration platform evaluation, and lower environment strategy

• Chair Architecture Review Committee (ARC) decisions; act as the primary technical DRI for cross-team, multi-system, and cost-impacting changes

• Establish and enforce engineering standards and production readiness criteria across all DPE-owned systems - testing requirements, CI/CD patterns, observability-as-code, logging standards, data contracts, Schema Registry governance, and what 'production-ready' means for emerging streaming and CDC capabilities

• Own data quality and observability architecture - dbt anomaly detection frameworks, schema validation, data drift alerting, and the platform standards that ensure consumers can trust the data they build on

• Define the technical strategy for self-service analytics: what platform capabilities enable Analytics Engineering to work independently, what guardrails prevent downstream breakage, and how DPE reduces its bottleneck over time

• Own evaluation, onboarding, and ongoing governance of DPE-managed tooling
  - Fivetran, Confluent, and equivalent platforms, including contract management, cost tracking, and deprecation decisions

• Own data sharing and egress patterns - access provisioning, cross-team data contracts, reverse ETL (Hightouch), and governed consumption paths for internal and external consumers

• Drive cost governance for platform infrastructure
  - Big Query slot reservations, query optimization, partition strategies, orchestration rightsizing, and cloud spend accountability across the full DPE stack

• Lead incident response for platform-level P1/P2 incidents: act as technical escalation point, facilitate blameless RCAs, and drive systemic fixes that prevent recurrence

• Produce exemplary technical artifacts - architecture decision records, solution design docs, RFCs - that create alignment and become the team's reference standard

• Mentor and elevate Staff and Senior Data Engineers; raise the technical ceiling through design reviews, code reviews, and hands-on pairing

• Partner cross-functionally with ML/Data Science, legal/security/compliance, and Dev Ops…
