Java Developer


About Masabi:

At Masabi, we are helping to make cities better places to live, work and visit, by enabling seamless, frictionless journeys on public transport systems. We are a SaaS company, developing a ticketing (fare payments) platform that allows people to buy and present tickets for public transport on their mobile phones or travel simply by tapping a bank card.

We believe a new fare payments system allowing passengers to just tap and ride, without needing to buy a ticket or understand fares, should be available to every passenger and every transit agency around the globe, without prohibitive costs or taking years to deliver, helping people move seamlessly from A to B.

Our Justride platform has been named Ticketing Technology of the Year 2019/2020 and is deployed in over 100 locations around the world, including New York, London, Boston, Las Vegas, Bucharest, Valencia, The Hague, Los Angeles, Sydney and many more. With an exciting industry-first mobile ticketing SDK, we are partnering with companies likeUber, Lyft, Transit, Moovit and many more to enable the purchase of public transport tickets within leading mobility applications.

Masabi has offices in London, New York, Denver and Cluj, and investors include Mastercard, Shell and Keolis.

Come join us on this exciting ride as we build the transit technology ecosystem of tomorrow.

The Role:

Masabi is looking for a Java / Kotlin developer to join our expanding Hub team.

The Hub team is responsible for systems and infrastructure powering key components of our Justride platform such as Customer Services, Partner & Retail portals, Ticket Vending Machines and others.

As a member of this team you will have the opportunity to work on a variety of products, all of which are highly visible to our customers. You will play a big part in defining and shaping the solutions that we implement, to ensure not only that our customers get a great experience, but also that we receive enough feedback about our implementation to iterate and improve upon it.

About you:

You will have solid core Java and object-oriented skills, and experience of implementing high quality high performance software. Kotlin and/or AWS experience would be a bonus. You should ideally have some DevOps environment exposure (managing Linux servers, interacting with AWS, understanding Docker, etc) as we are moving towards managing our own infrastructure via Terraform.

A desire to learn and eagerness to contribute are very important. There are plenty of features that are not yet designed, let alone implemented, so you must be keen to get stuck in and make your mark.

You don't have to know Kotlin to apply for this role as the team are more than happy to help you pick it up, but an interest in Kotlin will be beneficial.

Our Stack:

Kotlin / Java 11 / Groovy (Spock)

DropWizard / Jersey / MySQL

AWS EC2 / AWS Lambda / Terraform

Git / Gradle / Maven / Bamboo / Docker / Puppet

Some of our benefits:

  • Competitive salary package
  • 25 days of holiday per year plus the option to buy another 5 days pro-rated
  • Private Healthcare via AXA including pre-existing conditions and mental health
  • Life Insurance
  • Choice of workstation
  • Flexibility to work from home whenever you need to and flexible working hours (we are currently operating either fully remote or in a hybrid mode, please see Remote Working Policy below for more details)
  • You will now also be able to work from any country in the world for up to three months each year (tax laws permitting)
  • Pension scheme
  • Training allowance of up to £1000 per year
  • £200 annual allowance for any home office need or improvement
  • Onsite/video yoga classes
  • Childcare vouchers
  • Cycle to work scheme
  • Unlimited snacks and drinks, with regular free lunches (when in the office)
  • Regular social gatherings with a monthly allowance for each employee
  • Biannual company events
  • Fun and collaborative environment with a focus on making a difference in the world


We celebrate multiple approaches and points of view, striving to create an environment where everyone feels empowered to bring their full, authentic selves to work. Whoever you are, just be yourself. We encourage people from underrepresented backgrounds to apply and we don't discriminate. Also, please notify our team of any preferred pronouns at any point of your application.


In light of the continued Covid-19 risks, all interviews are expected to take place by phone or video.

Remote working:

Masabi's flexible working policy will allow you to work fully remotely, or from one of our offices in London, Cluj, New York, Denver or Boston.
