Research Analyst or Animal Welfare Specialist

(Please note that we are no longer accepting applicants for this position.)

We are expanding our research team as we examine different fish welfare issues and interventions. Depending on their prior experience and ability to take on additional responsibilities, the successful candidate will be designated as either Research Analyst or Animal Welfare Specialist.

How You Will Make a Difference

In this role, you will have the opportunity to help determine which intervention we will implement, and later be part of the process of carrying out this intervention. You will be responsible for:


  • Assessing welfare interventions to determine which are most impactful. This research will involve collecting and reviewing existing evidence on different species, welfare improvements, and priority countries.

  • Forming preliminary conclusions about various interventions. There are rarely clear conclusions on how best to improve fish lives. Your role will be to reduce uncertainty as much as possible based on existing data. 

  • Communicating our findings through blog posts, reports, and possible speaking events.

  • Assisting with the implementation of a pilot program based on our findings. This may involve periodic travel.

  • Developing our organizational systems and culture as we further build our team.

Additional Responsibilities (especially for Animal Welfare Specialist)

  • Conducting welfare assessments in aquaculture facilities. This will involve periodic travel.

  • Drafting white papers on current welfare conditions and recommended guidelines.

  • Advising our team on future interventions that we may pivot to.

  • Representing Fish Welfare Initiative and our findings to the wider animal welfare science community.

Who We're Looking For

Ideally you have all of the following characteristics, although we encourage you to apply even if you only have most of them. We expect you will be:


  • Committed to improving the lives of fish, with a demonstrated interest in animal welfare or effective altruism.

  • Both a skilled researcher and a quick-learning generalist.

  • Analytical and accustomed to data-driven reasoning.

  • Adept at finding common ground with parties with whom you may disagree.

  • Able to professionally communicate in technical terms to experts.

  • Comfortable traveling and working remotely.

  • Fluent in English.

  • Excited by intense and rewarding work in a young startup with future management opportunities.



For the Research Analyst position, you ideally have a bachelor's degree in a relevant field, such as biology or animal science, or have equivalent experience.


For the Animal Welfare Specialist position, you must have a master’s degree or equivalent in a relevant field, such as veterinary science, animal science, or zoology. Experience in fish aquaculture is preferable but not required.

The Fine Print

  • Location: Remote. Our co-founders are based out of London and the US, and we are able to hire people of all nationalities. The ideal candidate will be flexible to move, first to London and then to our country of implementation, but this is not required.

  • Position Status: Full-time.

  • Benefits: Salary depending on need, flexible hours, ability to shape a new organization, a cause you believe in

  • Start Date: As soon as possible.

Deadline: December 1

FWI is committed to building a diverse and inclusive team. We encourage people of every color, orientation, age, sex, gender, ethnicity, and ability to apply. Please contact us if you have any questions or concerns regarding accessibility, and we will endeavor to make adjustments throughout the process where possible.

Who We Are

Where We Have Come From

Our co-founders have been involved in animal advocacy and effective altruism for several years, and have both previously founded local effective altruism chapters. Since starting Fish Welfare Initiative, we have been awarded a $50,000 seed grant from Charity Entrepreneurship, spoken at conferences and visited fish farms, and conducted preliminary research.


Where We Are Going

Over the next few years, we are building a small and dedicated team that can reliably implement positive welfare changes for fish. If we succeed, we will have improved the lives of billions of fish. We are excited to see a growing number of advocacy groups focusing on fish and plan to one day act in coordination with a wider coalition of such groups.
