Connecting women across fertility and motherhood

About us

We created Peanut with the idea that no one should have to navigate womanhood alone. Especially the hard parts. Our mission is to provide a social network for women to connect across fertility, motherhood and beyond. So far, over 1 million women have joined to build friendships, find support, and learn from one another.

Since 2017, we’ve grown quickly across the US and other countries, and received numerous accolades from Apple, the New York Times, Good Morning America, and the BBC to name a few.

We recently closed our $17M Series A round and are backed by market-leading VCs including EQT Ventures, Index Ventures, Female Founders Fund and Sweet Capital (the brains behind King.com), enabling us to grow our team… now is a great time to join!

About the role

This is a full-time position.

You’ll report to Julien, our CTO, and work within our Engineering team of 10 people.

  • design, build, and test robust APIs and backend logic for our mobile apps (Ruby on Rails 6, PostgreSQL 11).

Many of our team work remotely from within the UK, the EU, and the US. We are entirely flexible about whether you would like to work remotely (from anywhere in the UK or the rest of the EU), or in central London, at our vibrant Peanut HQ.

We’ll simply expect you to join us in person for a few days every month to socialise and plan as a team (once the current health crisis is over).

Note that we do not consider candidates living outside the UK and the EU.


Depending on experience and location,

  • £70,000 to £85,000 gross salary per year (or local equivalent)
  • Participation in our equity pool
