Who we are:

At X, we're building an Everything App where people can connect, share ideas, and engage in meaningful conversations. Our mission is to foster freedom of speech and empower individuals to express themselves freely. We believe in the power of open dialogue and aim to create a platform for all perspectives.

We value:

  • Writing code rather than documents

  • Shipping products rather than talking about roadmaps

  • Big features rather than changing button colors

If this sounds like you, let’s talk.

What you'll do:

As a Mobile Engineer at X, you will play a pivotal role in shaping the future of our platform. Your responsibilities will include:

  • Architecting and developing mobile applications for iOS and/or Android platforms

  • Collaborating with cross-functional teams to design, develop, and implement new features

  • Writing clean, efficient, and maintainable code

  • Optimizing app performance and scalability

  • Troubleshooting and debugging to ensure a seamless user experience

  • Mentoring junior engineers and contributing to the team's growth

  • Staying up-to-date with emerging technologies and industry trends

Who you are:

We're looking for exceptional engineers who are passionate about our mission and have a strong desire to make a meaningful impact. The ideal candidate will have:

  • 2+ years of experience in mobile application development (iOS and/or Android)

  • Proficiency in Swift, Objective-C, Java, Kotlin, or other relevant languages

  • Experience with RESTful APIs, GraphQL and mobile application architecture patterns

  • Familiarity with Agile development methodologies and version control systems (e.g., Git)

  • Strong problem-solving skills and attention to detail

  • Excellent communication and collaboration skills

At X, our small but fast-paced team values innovation, creativity, and a strong commitment to our mission. As a Mobile Engineer, you'll have the opportunity to make a significant impact on the future of X and our aspiration to build the Everything App. 

If you're an exceptional engineer who shares our passion for freedom of speech, we'd love to hear from you.
