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 Manager, QA and Release, you are responsible for the dual-track integrity of our core software product releases and our bespoke delivery QA for client-specific builds. You act as the primary gatekeeper for production readiness, ensuring that every deployment, whether a platform-wide update or a custom client implementation, meets the rigorous GxP and regulatory standards required in clinical research. You will lead the QA team to balance speed with uncompromising quality.

Who are you

You believe that speed and high quality don't have to be mutually exclusive and excel at building continuous testing habits across product tracks.
You are passionate about coaching people, setting transparent performance goals, and helping individuals reach their highest potential.
You possess a natural curiosity for modern technology and an active interest in harnessing AI to optimize release cycles and scale workflows.
You value absolute precision and data integrity, aligning your daily execution with strict international healthcare standards without creating technical bloat.

What you'll be doing

Coordinate end-to-end between Product, Engineering, and Professional Services to execute seamless, compliant deployments for core software and client custom builds.
Mentor a talented team of engineers through consistent coaching and clear execution benchmarks to cultivate an environment of continuous growth.
Actively uncover new opportunities to leverage AI tools to trim manual workloads and streamline test documentation cycles.
Maintain and audit our Quality Management System (QMS) and align operational processes to comply with industry directives including HIPAA and regulatory guidelines.

What you'll bring

Extensive experience navigating Release Management within heavily regulated spaces (GxP, Life Sciences, or MedTech environments) handling SaaS platforms.
Proven track record in a direct people management or leadership role, showing a knack for sharpening team operations efficiently.
Strong foundational knowledge of standard clinical guidelines, such as ICH-GCP, FDA 21 CFR Part 11, and HIPAA data compliance.
Hands-on familiarity with, or a strong background in, implementing AI-driven tooling to support software testing protocols.

Our preference is for this role to be based in CET +/-2. Unfortunately at this moment we cannot accept applications from France, Spain, Belgium, Germany and 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.

Castor is a remote, globally distributed company, and as such we use location based salary bands. We believe compensation should be fair and transparent, without unnecessary complexity. For us, compensation means salary + equity + benefits, all of which are designed to support you in doing your best work,wherever you are.

This position is open to candidates across multiple regions. Before your interview is scheduled we will share the corresponding regional band for your specific country

Belonging at Castor

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