Lead Full Stack Engineer
App Framework Team
- 80% Backend / 20% Frontend
- 8+ Years
Zeta Global (NYSE: ZETA) is the AI-Powered Marketing Cloud that unifies identity, intelligence, and omnichannel activation into a single platform - powered by trillions of consumer signals and one of the industry’s largest proprietary databases. Our enterprise clients use the Zeta Marketing Platform (ZMP) to personalize experiences at the individual level across every channel.
The App Framework team is building something foundational: an Agentic App Builder platform on top of ZMP that enables teams across Zeta to develop, deploy, and operationalize applications that integrate with ZMP’s core capabilities - identity, intelligence, activation, and measurement. Think of it as the platform that powers the next generation of applications at Zeta, with AI and agentic workflows built into the development experience itself.
As a Lead Full Stack Engineer, you’ll shape the architecture of this platform from the ground up. You’ll partner with product owners and engineering teams across the organization to understand what application builders need, design the backend services and APIs that make it possible, and build the frontend experiences that make it intuitive. You’ll own what you build end-to-end - from requirements through production operations - with a focus on architectural simplicity, developer experience, and operational excellence.
We develop using AI-assisted workflows (Cursor, Claude Code) and ship through continuous delivery. This is a rare opportunity to build a platform that fundamentally changes how applications are created at an enterprise scale.
What you’ll Do:
- Design and build the Agentic App Builder platform - the services, APIs, and developer tools that enable teams to create, deploy, and manage applications on top of ZMP fast and at scale.
- Build intuitive frontend experiences in React/TypeScript that make the platform accessible and productive for application builders.
- Ship continuously and confidently through CI/CD, with observability, resilience and reliability built in from the start.
- Embed AI/LLM capabilities into the platform to enable agentic application development and intelligent automation.
- Use AI-assisted development tools as a core part of your workflow to accelerate delivery while maintaining high quality.
- Collaborate with teams across Zeta to gather requirements, align on integration patterns, and ensure the platform meets real-world application needs.
- Mentor engineers, lead technical initiatives, and help establish the engineering practices and standards for the platform.
What We’re Looking For:
8+ years of software engineering with a track record of building and operating platform-level systems. You’re deeply proficient in at least two of Python, Java, Ruby, or Node.js, with solid React/TypeScript skills on the frontend. You understand what it takes to build developer-facing platforms in the age of AI.
You bring hands-on experience with AWS services and you’re comfortable operating in multi-tenant, compliant environments. Continuous delivery, test-driven development, and agile are disciplines you practice with conviction. You’re already using AI-assisted coding tools and you’re excited about building platforms that leverage agentic workflows.
You’re a strong communicator who thrives on cross-team collaboration. You enjoy working with product owners to define problems, proposing architectures, building alignment, and then delivering. You bring energy and curiosity to your work, and you elevate the people around you.
Nice to Have:
- Experience building agentic developer platforms, internal tooling, or app builder/low-code systems.
- MarTech or AdTech domain knowledge (DSPs, bid stream processing, data-intensive platforms).
- Familiarity with our data stores: MySQL, Snowflake, Aerospike, DynamoDB, S3.
- Experience designing plugin architectures, SDK/API frameworks, or extensible platform systems.
