LoyaltyLion is growing and we would love for you to join us

LoyaltyLion allows ecommerce stores to create their own online loyalty and engagement program. Traditional loyalty programs are boring and outdated. Our goal is to keep innovating and testing new concepts.

The key is to constantly surprise customers, and that's what we strive to do. Our completely customisable platform helps increase purchase frequency, improves customer retention and encourages referrals.

We're looking for a motivated junior developer to work on interesting problems and shape the future of LoyaltyLion. You’ll be working across our entire platform with support from a small team of excellent engineers.

We're a small, agile team with a strong focus on the product - everything we build has a purpose and provides value. When it comes to development, clean and safe is our number priority. All our services are backed by strong test suites, and we strive to make our deployment process as deterministic as possible (we use Docker, ECS and Terraform).

Our day-to-day languages are Ruby and JavaScript - you'll need to be proficient in at least one of these; we'll teach you the other one if needed.

Some of the things you'll be doing:

  • Writing clean, robust, well-tested code
  • Developing our various apps and integrating with ecommerce platforms
  • Working on technical integrations with our partners such as Bronto and Dotmailer
  • Scaling our apps to work with the largest ecommerce stores
  • Turning lots of data into useful insights for our merchants
  • Helping us dream up and implement awesome new features

What we’re looking for:

  • Capable, smart and able to learn fast
  • Appreciates the value of a comprehensive test suite and reliable deployment process
  • Proven expertise with at least Ruby or JavaScript
  • Desire to work in a small, close-knit but well managed team
  • Other nice to haves: Postgres, AWS, Docker, own a dog/cat

What we offer:

  • Relaxed working environment and flexible hours
  • Opportunity to get stuck in and work on large production applications
  • A space at our bright, spacious office in Farringdon
  • Plenty of opportunities for tomfoolery (table football, VR headsets, Mario Kart tournaments)
  • Lots of food related perks: lunches, drinks, cupcakes

Salary: £25k - £30k, plus options
