Senior Software Engineer


LoyaltyLion is a data-driven loyalty and engagement platform trusted by thousands of ecommerce brands worldwide. Merchants use LoyaltyLion when they want a fully customised loyalty program that is proven to increase customer engagement, retention and spend. Stores using LoyaltyLion typically generate at least $15 for every $1 they spend on the platform.

Today LoyaltyLion works with over 6,000 fast-growth ecommerce retailers. Our mission is to help them succeed in the age of Amazon, where they may not be able to compete on price and logistics but can offer a better customer experience. One that makes customers feel valued, rather than like they are just another number.

Role information

We are looking for an experienced Senior Software Engineer to join the team here at LoyaltyLion to have a tangible impact on our team and product.

You will be working across our entire platform, from our merchant-facing web apps to our speedy third-party widgets. There’s ample opportunity to own certain product areas and really carve out your own niche.

Everything we build has a purpose and adds value. 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) and deploy at a rate of 5+ times per day.

We use Typescript and Ruby + Sorbet to ship robust and reliable code, and we have a technical Team Lead who is great at removing blockers and will enable you to produce your best work.

In the last year our team of Software Engineers have rebuilt our customer UI from the ground up and have put us in a great place to make future improvements.

Right now we’re working from home, and when we’re not we have a beautiful office space in Farringdon. One of the benefits of being a tech company that was used to home working prior to the lockdown, is that we are in a really good position to support newcomers remotely.

Some of the things you'll be doing:

  • Writing clean, robust, well-tested code
  • Working on technical integrations with our partners such as Bronto and Dotdigital
  • Scaling our platform to work with the largest ecommerce stores; some of our stores process up to 3,000 orders per minute during peak periods!
  • Turning lots of data into useful insights for our merchants; we process over two million orders a month and have a lot of data to work with.
  • Helping us dream up and implement awesome new features

What we’re looking for:

  • You’ve owned and lead the delivery of substantial projects in Typescript
  • Experience as a senior or lead engineer in a team
  • Autonomous and pragmatic: you know when to refactor and when to accrue debt
  • Desire to have an immediate impact on our platform, and the team around you
  • Other nice to haves: Postgres, AWS, Docker


Techstack list:

Ruby + Sorbet

What we offer:

Throughout COVID-19 we are working remotely for the time being, although our regular office is located in Farringdon. We’re committed to supporting anyone that joins us mid-pandemic in a way that enables you to; onboard smoothly, integrate with teams and feel a part of the team. In addition to this we offer:

  • Be part of the the first 75 employees that drive the future growth
  • Join at a major inflection point – ecommerce is booming and with it the demand for loyalty software like LoyaltyLion
  • Brand new Macbook, magic keyboard and any other tech or equipment you need to do a great job
  • Remote working
  • Flexible working
  • 25 days holiday + bank holidays + carry 13 days holiday over into the next holiday year
  • Company days out and events (virtual for now)
  • Home office budget
  • Cycle scheme
  • WeWork All access and an office space (post lockdown).

We’re constantly reviewing our perks and benefits and are currently looking to introduce a new set of benefits for the ‘new way of working’ for the time being.
