Connecting women across fertility and motherhood

We’re starting with our mission to build a community of women, who happen to be mamas.

Responsibilities and role

This is a full-time position. You’ll report to Julien, our CTO, and join our Engineering team of 10 people.

We’ll expect you to:

  • build and evolve features for our Android app using Kotlin (coroutines, serialisation), Dagger, Retrofit, sqldelight and test using Robolectric and Espresso.
  • take part in code reviews (GitHub).
  • regularly ship, monitor, and maintain features.
  • take the lead on new features as required.
  • contribute to planning and designing all new features.
  • support our PMs and CMs to diagnose issues.


As our CTO works remotely, and many of the team do, 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.


Depending on experience and location,

  • £65,000 to £75,000 gross salary per year (or local equivalent)
  • Participation in our equity pool

We offer 20 days holidays plus UK bank holidays.
