Job Description

What does the team do?

Caviar delivers delicious food to diners, with exceptional service and an effortless experience. Our team delivers this experience to companies; to office managers and hungry people at work. Our main products are catering and group-ordering.

We are a small team but we have a large impact on Caviar’s business. Our product drives high-margin orders to restaurants, which makes Caviar a more attractive partner to restaurants. On top of this, these orders make-up a significant part of Caviar's revenue and profit.

Many of the problems we solve are very different to the consumer-side of Caviar. We own these experiences that our customers, restaurants and Catering Captains rely on daily. This means that we have a wide-range of projects to work on.

We take a product-oriented approach to development. We have a dedicated PM and designer who we collaborate with daily. We don’t subscribe to a particular agile approach, but use agile principles as a guide.

What you will be doing:

  • Own and develop new features that improve the end-to-end experience for our diners and couriers.
  • Creatively solve tough technical challenges, both algorithmic and architectural.
  • Write concise code and sensible tests.
  • Design large-scale systems that keep things running smoothly.
  • Work closely with product managers to build the best product.
  • Have the opportunity to explore and build features across the entire technical stack, from the database all the way to the clients.
  • Work closely with product managers, designers, and internal teams to understand customer needs.
  • Leading by example to other members of the team
  • Get a balanced, supportive, fun working environment, and career path.
  • Make hungry people happy.
