Replit is the agentic software creation platform that enables anyone to build applications using natural language. With millions of users worldwide, Replit is democratizing software development by removing traditional barriers to application creation. About the Role We're looking for an AI-native product growth lead to own Replit's entire paid acquisition and lifecycle marketing engine as the single DRI. This is an IC role for someone who builds systems, not just campaigns. Someone who uses AI and automation aggressively to do what traditionally requires an entire team. You don't need an engineering background. You need the instinct to build: when you see a repetitive task, you reach for Replit or an API before you reach for a spreadsheet. You'll have data science and data engineering partners for infrastructure and modeling, and brand marketing will set creative direction. Your job is to turn that direction into a closed-loop optimization system: a self-improving system that turns performance data into better creative, optimizes spend across channels in near-real-time, and compounds every insight so nothing learned is ever lost. Each cycle, the system gets smarter. That's the engine you'll build and own. The ideal candidate has deep channel expertise across paid search, paid social, and lifecycle, but their real edge is building AI-powered workflows that scale creative production, automate measurement, and compound institutional knowledge. You Will Own full-funnel performance marketing across paid search & social, ASO, and lifecycle Build a self-improving creative engine: AI-driven ad generation, testing, and iteration that scales without scaling headcount Maintain a persistent knowledge layer so every experiment, result, and creative insight compounds automatically into the next cycle Own conversion signal quality end-to-end: right events, right audiences, right attribution, partnering with DE on the infrastructure Run a structured experimentation program wher

Replit is the agentic software creation platform that enables anyone to build applications using natural language. With millions of users worldwide, Replit is democratizing software development by removing traditional barriers to application creation. About the Role Replit is investing seriously in paid media — TV, CTV, online video, out-of-home, audio, social, and search — and we need the person who makes that investment work. This role is the internal owner of our media program: you'll direct our external media agencies, pressure-test their plans, steward the budget, and hold every dollar accountable for reaching the right audiences on the right channels at the right time. You'll report to the VP of Marketing and act as the connective tissue between our brand and growth teams and our agency partners. This is not a hands-on-keyboard activation role. You won't be living in Ads Manager — you'll be the person who briefs the agency, challenges the channel mix, catches the pacing problem before it becomes a budget problem, and translates campaign performance into decisions leadership can act on. This is the right role if you've sat on the brand side (or want to move there from a media agency), you know what a great media plan looks like and what a lazy one looks like, and you get energy from being the sharpest media mind in the room without needing to touch the platforms yourself. What You'll Do Agency leadership: Serve as the primary day-to-day partner to our media agencies. Set strategy direction, write clear briefs, run planning cycles and QBRs, and hold partners accountable for performance, optimization, quality, and business results. Plan interrogation: Review and challenge agency recommendations across every channel — TV, CTV, OLV, OOH, audio, social, search, programmatic. Catch weak rationale, frequency saturation risks, and budget misallocations before plans get approved. Budget stewardship: Own media budget pacing, forecasting, authorizations, and reconciliatio

Replit is the agentic software creation platform that enables anyone to build applications using natural language. With millions of users worldwide, Replit is democratizing software development by removing traditional barriers to application creation. Replit is changing who gets to build software. What started as a platform for developers has become an AI-powered creation platform where individuals, and teams can turn ideas into working apps, internal tools, dashboards, workflows, and websites faster than ever before. The company has had a fair amount of success with the outside world and in customer traction, particularly on the enterprise. We are looking for a PR Lead to help tell that story to the audiences that matter most: CIOs, CISOs, CFOs, business leaders, developers, analysts, partners, customers, and the press. This role will own communications for Replit’s marketplace, customer momentum, and business adoption. You will help position Replit as the AI platform that gives every team in an organization the ability to build, ship, and solve problems securely, without waiting months for traditional software cycles. The work will span the full range of communications: product launches, partnership announcements, customer stories, competitive positioning, analyst engagement, executive visibility, conference moments, speeches, thought leadership, vertical storytelling, and proof points that show how enterprises are using Replit to move from idea to production. You will work closely with Replit’s sales, partnership, marketing and leadership teams to shape narratives that resonate with both technical and business audiences. The right candidate understands the technology landscape and can operate comfortably across media, analysts, influencers, customers, partners, and internal teams. They should be able to explain why Replit matters in a world where AI is changing how software gets built and have the ability to change and evolve fast given the competitive nature of
