About the role

Key responsibilities & impact

Set technical direction for Agentic Ads, translating customer needs into an architecture and roadmap balancing rapid learning with long-term reliability.
Build agent-powered experiences that help businesses make informed growth decisions, translating user goals into understandable recommendations and appropriately authorized actions.
Design extensible integrations with external services using well-defined APIs and abstractions.
Partner with product and data teams to establish reliable measurement and connect product activity to business outcomes.
Develop intelligent automation that learns from performance signals and helps users improve outcomes within their goals and constraints.
Implement financial controls including scoped authorization, explicit approvals, budget limits, auditable decisions, clear reporting, and reliable pause controls.
Build reliable cross-platform workflows with durable state, idempotency, safe retries, reconciliation, observability, and recovery from failures, expired credentials, rate limits, and provider API changes.
Establish agent evaluations and production monitoring for plan quality, tool selection, policy compliance, spend safety, and verified execution.
Partner on experiments distinguishing attributed results from incremental customer value.
Lead ambiguous initiatives across product, design, AI, data, security, and partnerships.
Stay hands-on with implementation, define incremental milestones, mentor engineers, and own the quality and operation of shipped products.

Requirements

What you’ll need

A track record of Staff-level technical leadership on complex customer-facing products or platforms: setting direction, resolving ambiguity, and delivering through launch and production operation across multiple teams.
Strong hands-on software engineering and system design skills across APIs, data modeling, distributed systems, asynchronous workflows, and customer-facing product experiences.
Experience building and operating third-party integrations that remain correct under duplicate requests, partial failures, rate limits, changing schemas, and inconsistent external state.
Practical experience shipping LLM-powered products or agentic workflows, including tool use, orchestration, evaluations, and safeguards for actions taken against external systems.
Strong data and measurement judgment: experience using instrumentation and experiments to evaluate product outcomes, and the ability to reason about noisy data, delayed feedback, uncertainty, and correlation versus causation.
Sound judgment around systems that act on a user’s behalf, including authentication, authorization, sensitive data, approval boundaries, and limits on consequential actions.
Demonstrated ability to align cross-functional teams, explain technical trade-offs, mentor engineers, and drive execution without relying on reporting authority.
A product-minded approach to simplifying complex workflows for non-experts, with hands-on ownership from prototype through reliable production operation.
Preferred: Experience building advertiser-facing products, marketing automation, campaign-management tools, growth platforms, or software that helps businesses acquire customers.
Preferred: Experience integrating advertising or marketing APIs; familiarity with account onboarding, campaign lifecycles, and platform requirements.
Preferred: Working knowledge of conversion tracking, attribution, customer acquisition cost, return on ad spend, budget pacing, and the limits of optimizing with low conversion volume.
Preferred: Experience with experimentation, incrementality measurement, constrained optimization, recommendation systems, or decision-making under uncertainty.
Preferred: Experience building permissioned, multi-tenant products with approval workflows, budget controls, audit trails, and privacy-aware handling of customer and conversion data.
Bonus: Experience with agent tooling, durable workflow execution, delegated authorization, or evaluation frameworks for agents that take consequential actions.
Bonus: Experience connecting application events or server-side conversion signals to advertising platforms, or integrating creative generation and landing-page experimentation into growth workflows.
Bonus: Experience building for small businesses or first-time advertisers, where clear guidance, limited budgets, and sparse data shape the product.
Must be at least 18 years of age.
Must be legally authorized to work in the United States.
Experience with every ad platform is not expected; ad-serving infrastructure experience and an ML research background are not prerequisites.
