AI Marketing Specialist

At Castor, we’re modernizing the backbone of clinical research

Clinical trials are the gatekeepers of human health, yet the industry is still bogged down by fragmented, manual processes that can waste time and exclude patient populations. At Castor, we are building the operating system for the next era of clinical research.

We provide a modular cloud platform designed to run trials end-to-end. Our foundation is a robust Electronic Data Capture (EDC) system, supported by eConsent for recruitment and screening and eCOA to accurately capture patient reported outcomes. We don’t just stop at data collection; we use Castor Catalyst (our high-precision AI automation) to strip away the manual effort that historically makes research slow and expensive.

How we work: Trust over tracking

We are a remote-first company built on the belief that talented people do their best work when they have the agency to manage their own lives. We believe that high performance requires a foundation of trust, health, and cutting-edge support.

• Work-life integration: We don't believe in performative presence. We trust you to own your schedule and show up for your team, while also making space for your life outside of work.
• Deep work & async: We protect your time. We prioritize thoughtful, asynchronous communication so you can focus on solving hard problems without a calendar full of status update meetings.
• Radical candor: We value the truth over hierarchy. We give and receive direct feedback because that’s how we grow—as individuals and as a company.
  

Your mission and impact

As an AI Marketing Specialist you will be the marketing team’s internal AI architect and problem-solver. You will identify opportunities where AI can bridge the gap between marketing strategy and technical execution to drive growth. You’ll partner with stakeholders across the commercial organization to understand their bottlenecks, from content production to lead scoring and implement practical, automated solutions. Your work acts as a true force multiplier, accelerating our lead-to-opportunity velocity and allowing our elite team to focus on what matters most: innovation. 

Who are you

• You find more joy in connecting APIs and architecting data flows than in running traditional marketing playbooks.
  
• You are efficiency obsessed, with a drive to replace repetitive human tasks with smart, agentic workflows.
• You don't need a step-by-step manual; you can translate high-level growth strategies into technical requirements independently.
• You treat internal workflows as a product, ensuring that the automations you build are user-friendly and highly impactful for your teammates.
• You take pride in ensuring AI-generated outputs meet high brand standards and maintain strict adherence to security and compliance protocols.

What you'll be doing

• Manage an ecosystem of tools (Google Ads, LinkedIn, SEM Rush, WordPress) via APIs to create a unified, automated data flow.
  Act as the technical owner of our internal hub, ensuring it delivers automated, high-precision commercial insights.
  
• Maintain and scale the API endpoints and integrations that power proactive lead scoring and audience building.
• Engineer autonomous agents to process raw inputs (transcripts/research) into high-quality, brand-aligned collateral.
• Automate AI elements within WordPress to drive "hands-off" improvements in keyword performance and CTR.
• Eliminate manual reporting by building proactive, actionable recommendation workflows for the commercial team.
• Wire advertising and analytics platforms directly into agentic systems to optimize the funnel for high-intent lead generation.
  

What you'll bring

• 2-3 years in a technical role, with a demonstrated portfolio of custom-built automations or agentic workflows.
  
• API expertise, specifically in connecting disparate systems.
• Proven ability to build AI agents that perform multi-step tasks using LLMs to output structured data or collateral.
• Technical stack familiarity with tools like Jira and Salesforce is essential.

It would be nice if you had

• Experience in a Marketing Operations or Growth-specific technical role.

Our preference is for this role to be based in EDT +/-1

How we invest in you

High performance isn't sustainable without real support. We provide the infrastructure you need to stay healthy, focused, and rewarded.

• Downtime weeks: Once a quarter, the whole company shifts gears. No new shipping—just a week for deep focus, learning, or catching up so we can start the next quarter fresh.
• AI-first culture: We provide the tools and training to ensure you’re spending your energy on high-value work, not manual repetition.
• Real ownership: All Castor team members are offered options through our Employee Stock Option Plan (ESOP).
• Comprehensive wellbeing: Free access to Open Up for mental health, specialized sleep courses (for you and your family), and a budget to make your home office a place you actually want to be.
