About the job
At Compass, our mission is to help everyone find their place in the world. Founded in 2012, we’re revolutionizing the real estate industry with our end-to-end platform that empowers residential real estate agents to deliver exceptional service to seller and buyer clients.
We are looking for an experienced iOS 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
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
8+ years of professional iOS development experience building, architecting, and maintaining production-grade applications shipped to the App Store. The ideal candidate possesses deep expertise in modern Swift practices, including SwiftUI and Swift Concurrency, along with a strong grasp of scalable mobile architecture and the Apple deployment ecosystem.
Ability to collaborate with Product, Design and Engineering stakeholders to implement solutions which surprise and delight our customers
Master Computer Science fundamentals and iOS 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
