Principal Engineer, Customer Platform

Job Description: • Own the architecture and evolution of Hims & Hers’ Core Customer Platform—covering catalog, subscriptions, checkout, payments, and order management. • Design and implement distributed systems that scale to millions of transactions, balancing reliability, performance, and bolthires efficiency. • Lead technical strategy for service decomposition, data modeling, and API design across multiple product domains. • Shape and evolve shared infrastructure patterns—observability, messaging, caching, and data pipelines—to accelerate development across teams.

• Partner with Product, Data, and cross-functional partners to ensure platform capabilities enable seamless and secure customer experiences. • Prototype and implement critical systems, setting exemplars for quality, performance, and maintainability. • Mentor and guide senior engineers in system design, distributed architecture, and operational excellence. • Champion best practices for security, observability, testing, and reliability—embedding them into team culture and tooling. • Collaborate with infra and DevOps teams to ensure scalability, disaster recovery, and performance resilience in production.

• Drive architectural alignment across the organization, balancing long-term vision with near-term delivery needs. • Represent Core Platform engineering in cross-company forums, influencing both business and technical strategy. Requirements: • 15+ years of software engineering experience, with deep expertise in backend and distributed systems architecture. • A proven track record designing, building, and operating large-scale event-driven systems, leveraging technologies such as Kafka, SNS/SQS, or similar streaming and messaging platforms.

• Experience architecting core e-commerce or transactional platforms, ideally spanning catalog, checkout, subscriptions, payments, fulfillment, or order lifecycle domains. • Strong proficiency in microservice architectures, including API design, service boundaries, data modeling, and consistency strategies. • Deep understanding of event sourcing, CQRS, and domain-driven design (DDD) principles, and them pragmatically in complex, distributed domains. • Expertise in data pipelines and asynchronous workflows, including event orchestration, stream processing, and eventual consistency.

• Hands-on experience with cloud-native infrastructure (AWS preferred), container orchestration (Kubernetes, Docker), and infrastructure-as-code practices. • Proficiency in one or more modern backend languages (Node.js, Kotlin, Go, Python, or Java) and data technologies (PostgreSQL, DynamoDB, Redis, Elasticsearch, etc.). • Strong foundation in observability and operational excellence — building systems that are measurable, debuggable, and resilient under load (metrics, tracing, logging, alerting). • Experience establishing bolthires/CD pipelines, testing strategies, and release management processes for distributed services.

• Deep understanding of scalability, availability, and fault-tolerance tradeoffs, and the ability to make sound architectural decisions under ambiguity. • Proven ability to balance strategic thinking with hands-on execution—able to prototype, review critical code, and drive technical decisions that influence multiple teams. • Exceptional collaboration and communication skills—comfortable partnering with product, data, and operations teams to align technology with business outcomes. • Passion for mentorship and technical leadership, driving clarity, consistency, and excellence across engineering teams.
