Introducing Masabi

We build fare collection platforms that allow riders to seamlessly buy and present tickets for public transport either on their mobile phones, from a ticket machine, or even by tapping their bank card to travel.

Our Justride platform is used in over 150 locations worldwide, including some of the largest cities in the world. With our industry-first mobile ticketing SDK, we've partnered with large players in the transport space, including Uber, Moovit and Lyft.

Your own journey is important to us too. Choosing a role here means joining a network of innovators from all walks of life; a group of passionate individuals who consistently deliver. Here, you'll find the tools you need to build the career you want. Whether you're taking the direct route or trying a new path, we'll support you no matter what.

Location

// This role is available in a remote model for candidates based in the Pune region, India.

Type of role:

// This is a long-term contract available in a day rate model between £200-280 per day, depending on seniority.

Role Description

// Masabi is looking for developers to join our expanding Justride Validation team, which is responsible for both the backend server infrastructure powering our ticket validation systems and the software running on the devices in the field. You will be developing the Justride Inspect solution, which has provided ticket inspection and validation solutions for many transit agencies for more than a decade, and you will be working alongside a technically diverse team that have a range of expertise you can learn from.

Our services need to be extremely reliable - rush hours in big cities depend on them - and performance under heavy load is critical. Software on devices must be reliable and, in a constrained environment, equally performant.

You will have the opportunity to work on a variety of products, all of which are highly visible to our customers.

About you
• You will have strong core Java/Kotlin and object-oriented skills, and experience of implementing high-quality high-performance software.
• Some exposure to any of AWS, mobile development, and large scale operations would be a bonus, but equally valuable is being open to learning about some or all of these. You should also be the kind of developer that challenges the status quo and will be active in evolving our stack.
• Value collaboration, as you will learn how to excel as a team member by working closely not just with peers and colleagues from different areas of the business.
• You will adapt to implement high-quality, high-performance software whether it be destined for a cloud server, serverless or on a constrained device.
• Passionate about technology and customer experiences.
• Must be approachable, patient and an excellent communicator, a team player.
• Experience mentoring junior software engineers to improve their skills and make them more effective and productive.

Our Stack
• Java 8+ / Kotlin
• Gitlab / Bitbucket / Bamboo / Gradle / Maven / Artifactory / Puppet / Docker
• Cloud hosted, Terraform/Puppet managed, PCI-DSS certified platform infrastructure
• AWS services used include S3, SQS, CloudFormation, RDS, EC2, Lambda, IoT
• Native iOS Objective C/Swift, native Android Java/Kotlin, J2ObjC
