Lead Full Stack Engineer, Vertical Applications

Who We Are

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 Role

The Vertical Applications team builds web applications that bring the power of ZMP to specific industries – Healthcare, Political, Retail, and more. Every vertical comes with its own fascinating challenges: unique compliance requirements, distinct data models, and workflows that genuinely matter to the people using them. It’s the kind of work where you get to learn new domains, solve real problems, and see your applications make a tangible impact.

What You’ll Do

• Own vertical web applications from idea to production – working closely with product owners, designing the architecture, building it, shipping it, and running it.
• Architect backend services (Python, Java, Ruby, Node.js) with a focus on simplicity and reusability across verticals, so good patterns compound over time.
• Build polished frontend experiences in React/TypeScript/Ant Design System that connect seamlessly with backend APIs (REST, Thrift).
• Ship continuously and confidently through CI/CD, with observability, resilience and reliability built in from the start.
• Use AI-assisted development tools as a natural part of your workflow to move faster while keeping quality high.
• Weave AI/LLM capabilities into vertical applications, opening up new possibilities for each domain.
• Collaborate across teams – mentor fellow engineers, lead technical initiatives, and bring clarity to complex decisions for both technical and non-technical audiences.

What We’re Looking For

• 7+ years of software engineering with a history of owning and operating the systems you build. You’re deeply proficient in at least two of Python, Java, Ruby, or Node.js, with solid React/TypeScript skills on the frontend. Continuous delivery, test-driven development, agile and shift-left are things you genuinely practice – not just checkboxes on a process document.
• You’re comfortable building and operating scalable, distributed, high performant systems and navigating multi-tenant, compliant environments. You’re already using AI-assisted coding tools (Cursor, Claude Code, Gemini, Codex, AI Skills, MCP, Agentic Teams) and you’re curious about pushing those workflows further.
• You’re a strong communicator who enjoys working directly with product owners, proposing architectures, building consensus across teams, and then making it happen. You’re energized by learning new domains and collaborating with people who care about their craft.

Nice to Have

• MarTech or AdTech experience (DSPs, bid stream processing, data-intensive platforms).
• Domain knowledge in Healthcare, Political, or Retail verticals.
