Temporary Remote Web Developer Jobs in Houston, TX

Job Title: Senior MarTech Engineer / Web AI Systems Builder (Contractor)

Location: 100% Remote (Must align with North American Time Zones: EST, CST, or PST)

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.

• 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.
