Senior Android Engineer

We're a small, agile team working together to ensure that our merchants have the best possible mobile payments experience. We empower developers to deliver value for their customers with our out-of-the-box mobile SDKs that power payments for some of the world's best known brands.

Our goal for SDKs is simple: provide the greatest optionality, with the fastest integration, at the lowest cost. You'll play an important role in the development of the next generation of mobile payments and your work will define a best-in-class experience for the payments industry.

What you'll do:

• Working on our Flow SDK, where you'll have an opportunity to architect / design this SDK to scale it for the future.
• Championing Android SDK / app development best practices, coding conventions, and CI/CD integrations.
• Partnering with backend and product teams to deliver seamless, end-to-end user journeys.
• Working in the wider mobile team will give the chance to work on a large and complex domain, supporting many key pillars of the business.
• Supporting the wider mobile team through Architecture and PR reviews.
• Working independently and managing multiple priorities, taking complete ownership of what you've built.
• Questioning, 'what can we do better?' and have a curious mind that challenges the status quo.
• Asserting the quality of your code with unit tests and automation tests.
• Establishing best practices and processes for the engineering team's overall development.

Do you have experience in iOS development?, * Several years of experience in Android development.
