Marketing Engineer (AI Agents)

Overview

Cresta is seeking its first Marketing Engineer (AI Agents) to own the systems behind how Cresta shows up on the internet, including the technical decisions for cresta.com and the development of custom AI agents for marketing use cases.

What you'll do

• Own how cresta.com is built end to end, including its structure, content flow, and connections to other systems.
• Set the technical vision for how the website stack and CMS should evolve to meet business needs and marketing workflows.
• Partner with brand and design on interactive experiences, architecting and building the creative vision.
• Own the component system so the site stays consistent as it grows.
• Own the instrumentation where the site meets the GTM stack, including forms, gated content, event tracking, and attribution, in partnership with marketing ops.
• Build the technical foundation for localization, including locale routing, URL architecture, and hreflang, partnering with the web strategy lead on CMS translation workflows and content structure.
• Put in engineering practices that enable fast shipping without breaking things.
• Ship the technical work behind SEO and AEO programs, in partnership with the owners of those programs.
• Develop, configure, deploy, and optimize AI agents on Cresta's platform for marketing use cases, working alongside the forward deployed engineering team.
• Take agents from prototype to production, including evaluation criteria, guardrails, and human review steps for prospect-facing work.
• Provide a feedback loop to product and engineering teams by identifying gaps, building custom tooling, and influencing the roadmap.

What you'll need

• 7+ years working in software development, web development, AI/ML engineering, or growth engineering.
• Strong across the stack, including application code, APIs, data, and infrastructure, in Python, TypeScript, Node, or similar.
• Familiarity with AI/ML concepts.
• A track record of learning a domain fast and going deep.
• High agency: defining your own work, shipping without being told what to build, and treating gaps as yours to close.
• Strong understanding of general AI agent frameworks, function calling, and retrieval-augmented generation (RAG).
• Comfortable as the deepest technical voice on a non-engineering team, scoping ambiguous requests and explaining tradeoffs to marketers.
• Ownership: treating the outcome as yours, including when something breaks or was built badly before you arrived.

Nice to have

• Experience owning a marketing website.
• Technical SEO and AEO experience grounded in tests rather than theory.
• Marketing and GTM systems integration experience with HubSpot, Salesforce, Marketo, Segment, GA4, or GTM.
• Hands-on experience with large language models (LLMs) and prompt engineering techniques.

Details

• Location: United States (Remote).
• Compensation: base salary range of $160K - $280K plus equity, based on experience, skillset, and location.
