Role Overview

As Cresta’s first Marketing Engineer (AI Agents), you'll own the systems behind how Cresta shows up on the internet. In this role, you will own the technical decisions behind cresta.com and help shape how Cresta puts its own AI agents to work for marketing use cases. You'll architect and build our web platform, create the tooling that lets marketers ship without an engineer in the loop, and develop custom AI agents on Cresta's platform. This position requires strong engineering fundamentals, high agency, and the ability to go deep in an unfamiliar domain quickly. If you are self-driven, AI-native, and eager to own something end to end, this role is for you.

Responsibilities

The web platform

• Own how cresta.com is built end to end: how it’s structured, how content flows through it, and how it connects to everything else.
• Set the technical vision for how our website stack and CMS should evolve to meet the growing needs of our business and the rapidly changing workflows of the marketing team. Our website runs on Webflow today.
• Partner with brand and design on the interactive experiences that carry our identity. They set the creative vision; you architect and build it. Own the component system so the site stays consistent as it grows.
• Own the instrumentation where the site meets our GTM stack — forms, gated content, event tracking, and attribution — so data lands cleanly downstream, in partnership with marketing ops.
• Build the technical foundation for localization as we scale into new markets, including locale routing, URL architecture, and hreflang, partnering with our web strategy lead on CMS translation workflows and content structure
• Put in the engineering practices that let us move quickly without breaking things. Enough to ship with confidence, not so much that it slows us down.
• Ship the technical work behind our SEO and AEO programs, in partnership with the owners of those programs

AI Agent Creation

• Develop, configure, deploy, and optimize AI agents on Cresta's platform for marketing use cases, working alongside our forward deployed engineering team.
• Take agents from prototype to production, including the evaluation criteria, guardrails, and human review steps prospect-facing work requires.
• Provide a tight feedback loop to our product and engineering teams — identifying gaps, building custom tooling, and influencing the roadmap through what you learn deploying against a real audience.

What We’re Looking For

• 7+ years working in software development, web development, AI/ML engineering, or growth engineering.
• Strong across the stack — application code, APIs, data, and infrastructure — in Python, TypeScript, Node, or similar.
• Familiarity with AI/ML concepts. Hands-on experience with large language models (LLMs), and prompt engineering techniques are strongly preferred.
• A track record of learning a domain fast and going deep. You've been dropped into something unfamiliar and become the person other people come to. 
• High agency. You define your own work, ship without being told what to build, and treat 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. You treat the outcome as yours, including when something breaks or was built badly before you arrived.

Nice To Have

• Experience owning a marketing website. Useful context, not a hard requirement.
• Technical SEO and AEO experience grounded in tests rather than theory.
• Marketing and GTM systems integration: HubSpot, Salesforce, Marketo, Segment, GA4, GTM.
