Senior MarTech Engineer

Job Summary
We are seeking an autonomous, entrepreneurial Senior MarTech Engineer / AI Web
Builder for a dedicated contract engagement to accelerate our B2B SaaS pipeline and
scale our AI brand presence across all devices. In this contract role, you will take
immediate ownership of our high-performance marketing web properties, with a heavy
emphasis on mobile-first optimization, and engineer our web-to-lead pipelines.
You will combine a high-speed frontend stack (Astro and Contentful) with cloud-hosted
AI orchestration (AWS Bedrock) to optimize our marketing content for LLM search
engines (like Perplexity, OpenAI Search, and Gemini). Critically, you will build and
manage a Model Context Protocol (MCP) server to securely connect our technical
documentation directly to external AI agents. This role requires a disciplined remote
contractor who designs flawlessly for mobile screens, delivers exceptional mobile
performance, and stays fully synchronized during North American core business hours.

Key Responsibilities
● Execute Mobile-First Web Builds: Rapidly build, optimize, and maintain
responsive marketing sites, product feature matrices, and interactive tools using
Astro’s island architecture and Contentful headless CMS, prioritizing mobile
layouts and fluid viewport adaptation.
● Optimize Mobile Performance & UX: Ensure perfect mobile Core Web Vitals (LCP,
INP, CLS) by minimizing Javascript payloads on mobile devices, optimizing
mobile asset loading, and designing touch-friendly, intuitive UI controls for AI
conversational elements. [1]

● Drive B2B AI Visibility (LLMO/GEO): Structure and optimize site metadata,
technical schemas, and product content to maximize our inclusion in mobile
enterprise AI tool evaluations and conversational LLM queries.
● Deploy MCP Server Architecture: Design and deploy an operational Model
Context Protocol (MCP) server ecosystem to securely expose our API schemas
and product documentation directly to developer-facing AI agents (e.g., Cursor,
Claude Desktop).
● Integrate Cloud AI Features: Program and implement intelligent user experiences
(such as dynamic, mobile-optimized ROI calculators and chat modules) using the
AWS ecosystem (Lambda, Bedrock, OpenSearch).
● Maintain Cross-Device Enterprise Testing: Author and run robust end-to-end
integration test suites with Playwright, mimicking both mobile and desktop
viewports to prevent regressions in mobile signup flows, multi-step pricing
layouts, and third-party webhooks.
● Optimize Revenue Operations (RevOps): Connect mobile and web intent data
directly to our revenue engine, building smooth, automated API connections into
HubSpot CRM and triggering immediate sales engagement sequences via
Outreach.

Contractor Requirements
● Availability: Must be fully available to work during North American business
hours (overlapping at least 6 hours daily with EST/CST/PST teams) and join
standups/Slack channels in real-time.
● MarTech & Mobile Web Expertise: 4+ years of professional full-stack experience
building scalable sites using Astro and advanced content modeling within
Contentful, with a proven portfolio showcasing high-performance mobile web
designs.
● Model Context Protocol (MCP): Direct, hands-on experience constructing or
deploying MCP servers to facilitate context-sharing between web architectures
and AI applications.
● AWS Cloud Engineering: Production experience managing serverless
components on AWS (Lambda, Gateway, S3, IAM) for full-stack frontend-to-AI
orchestration.
● Cross-Device Testing Automation: Deep familiarity writing and executing
integration tests with Playwright, specifically targeting mobile viewport

emulation and touch interaction behaviors across complex, dynamic checkout or
pricing pages.
● Remote Contractor Setup: Must have a dedicated home office setup, reliable
high-speed internet, and a proven history of shipping code independently without
micro-management.

Nice-to-Have Skills
● Strong production knowledge of the HubSpot API (Custom Objects, lifecycle
staging, and marketing attribution models).
● Experience with the Outreach API/Webhooks to auto-enroll hot leads based on
high-intent AI web behaviors. [1]
