Replit is seeking a Staff Software Engineer to help define and build Agentic Ads, a new product area focused on using AI to make customer acquisition more accessible to businesses built on Replit. This is a hands-on Staff role where you will own technical architecture, lead cross-functional delivery, mentor engineers, and drive an ambitious vision into incremental customer value.
You will set technical direction for Agentic Ads by translating customer needs into architecture and roadmaps that balance rapid learning with long-term reliability. You'll build agent-powered experiences that help businesses make informed growth decisions, designing extensible integrations with external services using well-defined APIs and abstractions. Working closely with product and data teams, you'll establish reliable measurement practices, connect product activity to business outcomes, and address data quality and uncertainty.
Key responsibilities include developing intelligent automation that learns from performance signals, making financial control a core product requirement through scoped authorization, explicit approvals, budget limits, and auditable decisions. You'll ensure cross-platform workflows are reliable with durable state, idempotency, safe retries, and recovery from partial failures. You'll establish agent evaluations and production monitoring for plan quality, tool selection, policy compliance, and spend safety, while leading ambiguous initiatives across product, design, AI, data, security, and partnerships.
This role sits at the intersection of AI, business growth, measurement, and trustworthy automation. You'll focus on intelligent, advertiser-facing software—not ad-serving infrastructure or real-time bidding engines. Success means helping businesses acquire qualified leads and customers through clear guidance, user control, and evidence-based decision-making.
REQUIREMENTS:
- Track record of Staff-level technical leadership on complex customer-facing products or platforms, including 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 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
- Product-minded approach to simplifying complex workflows for non-experts, with hands-on ownership from prototype through reliable production operation
PREFERRED QUALIFICATIONS:
- Experience building advertiser-facing products, marketing automation, campaign-management tools, growth platforms, or software that helps businesses acquire customers
- Experience integrating advertising or marketing APIs; familiarity with account onboarding, campaign lifecycles, and platform requirements
- Working knowledge of conversion tracking, attribution, customer acquisition cost, return on ad spend, budget pacing, and the limits of optimizing with low conversion volume
- Experience with experimentation, incrementality measurement, constrained optimization, recommendation systems, or decision-making under uncertainty
- Experience building permissioned, multi-tenant products with approval workflows, budget controls, audit trails, and privacy-aware handling of customer and conversion data
- Experience with agent tooling, durable workflow execution, delegated authorization, or evaluation frameworks for agents that take consequential actions
- Experience connecting application events or server-side conversion signals to advertising platforms, or integrating creative generation and landing-page experimentation into growth workflows
- Experience building for small businesses or first-time advertisers, where clear guidance, limited budgets, and sparse data shape the product
