Lead Software Engineer, Full Stack (Enterprise Platforms Technology)

We are hiring a Lead Software Engineer to build the AI-powered marketing content layer - the systems that generate, assemble, review and publish marketing content across email, mobile app, site placement and push notifications. You will work on LLM-integrated content generation pipelines, channel-specific content builds, and AI-assisted compliance workflows that ensure every piece of marketing content meets regulatory standards before it reaches customers.

• Contribute to multi-agent orchestration systems that coordinate content compliance review, audience selection, and campaign dispatch.

• Build evaluation and observability tooling for LLM outputs – golden dataset benchmarks, A/B content quality metrics and drift detection.

• Develop template and component systems that allow marketers to assemble compliant content from pre-approved building blocks across channels.

• Write well-tested, production-ready code and participate in CI/CD pipeline development, including model evaluation pipeline.

• Lead the design of end-to-end content generation features; write architecture proposals and drive cross-team alignment

• Define guardrail frameworks for LLM outputs – toxicity filters, brand voice enforcement, compliance boundary checks – and establish operational runbooks.
