What is a senior Kotlin developer?

Senior Kotlin Developers are experienced software engineers who specialize in developing applications using the Kotlin programming language. They typically work on backend services, Android applications, or cross-platform solutions, leveraging Kotlin’s modern features and interoperability with Java. In addition to coding, they often lead teams, design software architecture, mentor junior developers, and ensure best practices in software development. Their expertise is valuable for companies seeking efficient, scalable, and maintainable codebases, especially in environments where Kotlin is a primary technology.

What are some common challenges senior Kotlin developers face when integrating Kotlin with existing Java codebases?

Senior Kotlin Developers often work on projects where Kotlin is gradually introduced to legacy Java codebases. A key challenge is ensuring seamless interoperability between Kotlin and Java, which requires careful handling of nullability, type conversions, and tooling compatibility. Developers also need to maintain consistent coding standards and documentation across mixed-language projects. Effective communication with team members is essential to coordinate refactoring efforts and share best practices for code migration.

Job description

We are looking for an experienced Android engineer to help Compass build a platform that makes the home buying or selling experience delightful. You will be one of the technical leaders in your immediate team. You will work with other engineers and your Product and Design counterparts to take projects from idea to done with a high degree of autonomy and ownership. You will be responsible for understanding Product requirements and the customer problems they are aiming to solve, distilling them into manageable subparts that can be divided across other engineers on the project.

During a project's execution, you will act as a leader ensuring any technical questions and trade offs are considered pragmatically, with a well-reasoned and understood solution being executed upon. You will guide more junior engineers with technical problems, ensuring that they follow best practices from an engineering and operational excellence perspective. Your influence won't end once a project ships: you will be relied upon by Product and Design to give an engineering perspective on how we can iteratively improve a product to better benefit our customers.

Outside of product-driven projects, you will work with other engineers to determine how to push our platform forward, devising engineering-led initiatives that ensure we can work quickly and efficiently while maintaining a high standard of operational excellence. You will also act as a mentor for more junior engineers, helping them grow from both a technical and career perspective.

What you will do:  

  • Work in a startup-like environment building agile products and services
  • Collaborate closely with engineers on your team, engineers on other teams, as well as your product and design counterparts to successfully launch projects which solve real-world customer problems
  • Act as a strategic partner to Product and Design, using technical insights to influence the product roadmap and proactively suggesting architectural changes that enable new categories of user experiences
  • Guide the team to make technical trade offs necessary to bring product initiatives to fruition, weighing different approaches and arriving to a recommended solution, detailing its pros and cons
  • Independently define, decompose, and lead delivery of complex projects, may lead other engineers
  • Modularization and Architecture. Architect and lead the transition toward a highly modularized codebase to improve build speeds and team fungibility, ensuring our architecture scales with our growing engineering organization.
  • Perform code reviews, design reviews, and write high quality tests
  • Have a strong stance and advocate for efficient, scalable, and extensible approaches that solve technical problems in a manner that stands the test of time
  • Hold yourself and the team to a high standard of code quality and operational rigor, ensuring that code is well-tested, and your systems have appropriate monitoring, alerting, and runbooks implemented
  • Become the subject matter expert for one or more services in your domain
  • Create clear and concise documentation (diagrams, service descriptions, decisions, runbooks)
  • Identify and remove bottlenecks to address inefficiencies in the developer experience 
  • Oversee and mentor junior engineers on the team, building their technical skills and ensuring that they understand best practices around engineering and operational excellence

What we look for: 

  • BS in CS or equivalent practical experience
  • 9+ years of professional Android development experience using Kotlin and shipping apps to the Play Store
  • 3+ years of experience with modern Kotlin development practices, such as Jetpack Compose and Flow. Experience with Kotlin Multiplatform is a plus but not mandatory
  • Ability to collaborate with Product, Design and Engineering stakeholders to implement solutions which surprise and delight our customers
  • Master Computer Science fundamentals and Android design patterns and best practices
  • A sheer eye for design and attention to detail, the products you build should not merely be functional but should take in context and anticipate our customer's needs in a beautiful way
  • Experience leading the development of a project from planning to release, dispatching work among a team, mentoring and guiding junior engineers
  • Experience with AI tools 
  • Experience integrating with RESTful server-side services
  • Experience with Scrum/Agile development methodologies
  • Excellent verbal and written communication skills
  • Passion about mentoring and helping more junior engineers to grow

Bonuses and restricted stock units may be provided as part of the compensation package, in addition to a full range of benefits. Base pay is based on market location.
