Nafundi is seeking a full-time Senior Android Developer to play a lead role in the evolution of Open Data Kit, a series of open source tools for social good organizations to collect data quickly, accurately, offline, and at scale. The ideal candidate has experience with high-level software system design, modernizing legacy codebases, and writing maintainable code.

Some of the decisions you will participate in making and implementing solutions for:

• Should this requested feature (e.g., messaging users) be implemented in the existing app or in a companion app?

• Adding minor functionality (e.g., a new type of text input) requires updating multiple components. How do we reduce interdependencies?

• How can the geo coordinate implementations in the Collect app evolved to better match the ODK XForms specification while continuing to serve the needs of users with existing forms?

• How do we rework the user interface of Collect to take advantage of larger screen devices without disrupting the hundreds of thousands of users who have smaller format devices.

Responsibilities include:

• Thinking strategically and systematically about how to evolve a legacy codebase

• Designing and building on a number of Java-based tools

• Working with the community to specify and implement new features and tools

• Reviewing other community members’ code

• Implementing code quality best practices (testing, separation of concerns, etc)

• Increasing our score on the Joel Test

Minimum qualifications:

• Five or more years of professional software development experience on Android

• Experience with large refactors or rewrites of legacy code

• Experience leading a team of developers with varying skill levels

• Demonstrated ability to read carefully, write clearly, and think methodically

• Demonstrated ability to self-motivate (side projects, open source contributions)

Preferred qualifications:

• Experience working on large Java code bases

• Experience working remotely and leading globally distributed teams

• Interest in user interfaces, user experience, visual design

• Code contributions to open source projects

• Experience living and working in underserved communities

What we offer:

• Contribute to an open-source project with immense social impact

• Work with a distributed, open, and fun community eager for improvements

• Flexible multi-year contract-based arrangement

• Flexible hours, remote work, and location independence
