• Technical Leadership & Delivery: Partner directly with the Senior Engineering Manager to translate business and marketing roadmaps into resilient technical architecture, pragmatic milestones, and maintainable codebases.
• MarTech Integrations: Oversee the architectural design and integration of third-party marketing platforms, analytics suites, customer data platforms (CDPs), and CRM systems (e.g., Salesforce) without compromising web performance or security.
• Mentorship & Engineering Excellence: Set engineering standards, conduct high-signal architecture and code reviews, and mentor mid-to-senior engineers across modern full-stack web development and emerging AI patterns.
• Cloud & DevOps Rigor: Collaborate with Platform and DevOps teams to maintain robust CI/CD pipelines, container orchestration, and automated cloud infrastructure using modern Infrastructure as Code.

What We Are Looking For

Minimum Requirements:

• 8+ years of progressive software engineering experience, including 2+ years in a Tech Lead, Staff, or Principal Engineer capacity architecting high-scale web platforms or distributed services.
• Hands-On Agentic AI Depth: Practical experience designing, building, and deploying autonomous AI agents and LLM-powered workflows in production (utilizing frameworks like LangGraph, CrewAI, AutoGen, or custom agent architectures, alongside structured tool/function calling and RAG).
• Modern Web Mastery: Deep expertise across TypeScript/JavaScript, modern front-end frameworks (e.g., React, Next.js), and backend services built with Node.js or Python.
• Web Systems & Cloud Infrastructure: Strong grasp of modern rendering paradigms (SSR, SSG, ISR), CDN/edge platforms (e.g., Cloudflare, CloudFront), REST/GraphQL APIs, and cloud environments (AWS, Docker, Terraform).
• Pragmatic Partner: Exceptional ability to collaborate across engineering management, product, and non-technical marketing stakeholders, breaking down ambiguous goals into actionable technical plans.

Preferred Requirements:

• Prior experience in the Marketing Technology (MarTech) space, including headless/decoupled CMS platforms (e.g., Contentful, Sanity), A/B testing engines, and conversion rate optimization (CRO).
• Practical experience integrating enterprise CRMs, marketing automation engines, and data pipelines (e.g., Salesforce, HubSpot, Segment).
• Familiarity with international data privacy laws (GDPR, CCPA), accessibility standards (WCAG), and enterprise compliance standards (e.g., SOC 2).
