Manager, QA and Release

Open 61d

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 our Manager, QA and Release, your primary objective is to come in and transform our QA organization into an AI-first power engine. You will champion modern LLM workflows, agentic test generation, and predictive release models, balancing game-changing engineering speed with bulletproof regulatory integrity. You will be responsible for the dual-track integrity of our core software product releases and our bespoke delivery QA for client-specific builds.


Who are you

  • You don't just use AI on the side; you believe AI is the core future of Quality Engineering and actively look for ways to eliminate manual testing overhead through prompt architecture and autonomous tooling.
  • You are energized by changing mindsets, coaching engineers through new ways of working, and driving the cultural shift toward continuous, AI-augmented automation.
  • You look at release bottlenecks as engineering problems to be solved with smart workflows rather than just throwing more headcount at the team.
  • You know how to innovate boldly while establishing smart, human-in-the-loop guardrails to protect data integrity and safety standards.


What you'll be doing

  • Pioneer the integration of generative AI tools and LLM test generation to drastically reduce regression cycles and defect triage times.
  • Transform our existing QA practices by training on AI-assisted testing frameworks and modern engineering habits.
  • Manage seamless go/no-go release gates across our Core platform updates and bespoke client builds to maintain high delivery predictability.
  • Leverage intelligent automation to auto-generate audit-ready test documentation, traceability matrices, and QMS logs with minimal manual effort.
  • Implement smart environment strategies and branching controls that allow fast core updates without breaking custom client configurations.


What you'll bring

    • Demonstrated experience or deep expertise leveraging AI/LLM tools (e.g., Copilot, Claude/OpenAI APIs, agentic test workflows) as a force multiplier in software delivery.
    • A track record of leading, modernizing, and upskilling engineering/QA teams through significant process transformations.
    • Strong hands-on background in UI/API test automation frameworks (e.g., Playwright, Cypress) and modern CI/CD release pipelines.
    • Ability to apply AI innovation safely within compliance-heavy boundaries (such as GxP, FDA 21 CFR Part 11, or HIPAA environments).


    Our preference is for this role to be based in CET +2/-4. Unfortunately at this moment we cannot accept applications from France, Spain, Belgium 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.


    Compensation at castor

    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.


    Our remote setup is designed to support you as a whole person—your family, your mental health, and your authentic self. We don't care about your background as much as we care about your perspective and your expertise. We strongly encourage applications from women, people of color, and the LGBTQ+ community. Please feel free to share the pronouns you use (for example she/her/hers, he/her/his, they/them/theirs, etc.).
