Kotlin / Java Developers

Full Time

Great at Java but tired of working for the bank? Want to create products that users love instead of spending a week just to add a field to a form? Join us at SimplePay, where we're pursuing a modern approach to Java, using the Kotlin language.

SimplePay and Our Approach to Development

SimplePay is an online payroll software for South Africa, Ireland, Singapore and Hong Kong. Our software lets thousands of small business owners (and their accountants) run their payrolls accurately, without headaches, so they can focus on the challenge of building their businesses. You can find out more about the team here and about the technical side of the business on the developer blog, here.

We love solving problems for our customers and ourselves  with good code. That is why our founder, a developer himself, started the company and is still involved in improving the software every day. We use proven infrastructure and frameworks, so that we can focus on well-designed code. We have excellent test coverage and all PRs have to pass CI before merging.

You'll be joining a high-performing team, working alongside our existing RoR developers and pioneering our Kotlin / Java development. Every bit of code you write makes a difference no matter how small. Our culture of constant feedback and improvement means that if you like the thought of continual growth as a developer (non-technical skills included), you’ll be right at home.

You'll be involved in delivering exciting new HR products to our client base of more than 23,000 companies, as well as transitioning part of our existing Ruby on Rails payroll system to Kotlin. Within our existing team, our developers own the features and bugs they work on and are responsible for ensuring that the correct people from other teams get involved where needed. All PRs are reviewed and discussed. Collaboration is key. Joining us as part of our new team, you’ll receive the same support and carry the same level of responsibility and ownership over your work.

Our development team was already mostly remote even before the pandemic, so we have a strong remote working culture.

Summary of the Role

  • Kotlin (familiarity with JRuby will be a bonus) 
  • PostgreSQL (mostly through an ORM, but raw SQL queries do come in handy sometimes)
  • Others: Jenkins, AWS, Sentry, Vue.js where it makes sense


Due to our full pipeline, we are ideally looking to hire developers who have at least five (5) years of software development experience in  Java web development, with a back-end focus (bonus points for Kotlin experience). Ideally your experience will have included working with systems that have substantial levels of business logic as our work deals a lot with the intersection of HR, payroll, regulatory, compliance and reporting concerns.

You will also need

  • Good knowledge of SQL (bonus points for PostgreSQL)
  • Strong grasp of object-oriented design, bonus points for DDD knowledge
  • Ability and willingness to learn substantial amounts of domain knowledge - full training provided

Full time or hybrid remote in our awesome Cape Town offices or fully remote anywhere within UTC+0 to UTC+8 time zones. Your choice.

Additional Details
In the "Additional Details" section of the application, please include:

  • The time zone in which you reside,
  • A link to a PR created or an issue logged for an open source project, and
  • Tell us why you would like to join SimplePay specifically.
