AI Implementation 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.

We are also hiring AI automation/implementation roles specifically for our Product and Marketing teams

Your mission and impact

As an AI Implementation Specialist you will be Castor's internal AI problem-solver, working across the organization to identify opportunities where AI can streamline operations and improve efficiency. Reporting directly to the CFO, you'll partner with teams in Finance, Sales, Operations and beyond to understand their challenges and implement practical AI-powered solutions.

This is a highly autonomous, impact-driven role perfect for someone who loves learning new domains quickly, solving real business problems, and applying the latest AI technologies in creative ways. You'll be the go-to person for 'Can AI help with this?' questions, turning manual, time-consuming processes into automated, intelligent workflows.

Who are you

• You are more interested in building a working solution than in theoretical research
• You have enough commercial understanding to manage diverse stakeholder requirements (like revenue recognition or sales funnels) and can prioritize your workload based on strategic impact
  
• You have the soft skills to proactively seek out information and push for clarity when requirements are abstract
• You are deeply excited by AI and spend time experimenting with new LLM capabilities and automation tools

What you’ll bring

• 1-3 years of experience in a technical role (solutions architect, automation, or related fields)
• Programming skills in Python (or similar language) and ability to work with APIs and scripts
• Proven track record of advocating for and implementing AI tooling (i.e.ChatGPT, Claude, OpenAI API, or similar) across multiple business areas
• Proven ability to learn new technologies and business domains quickly in a fast-paced environment
  
• Excellent communication skills for cross-team and timezone collaboration and technical storytelling
  

Accepting candidates +2/-2 CET. At this time, we cannot accept applications from France, Germany, Spain, Bulgaria, or Switzerland.

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.

• Rest is non-negotiable: Unlimited annual leave with 25-day minimum. We don’t just allow time off; we expect you to take it.
• 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.
• Annual bonus: A guaranteed "Happy Holidays" bonus every December.

Belonging at Castor

We build products to make research accessible to everyone, and we believe our team should reflect that same diversity.
