What is an app optimization?

An App Optimization job focuses on improving the performance, visibility, and user experience of mobile applications. This includes tasks such as App Store Optimization (ASO), performance tuning, A/B testing, and user engagement analysis. Professionals in this role work to increase app downloads, enhance speed, fix bugs, and improve retention rates. They often collaborate with developers, marketers, and data analysts to ensure the app performs effectively across different devices and platforms.

What are some common challenges faced by professionals in app optimization roles?

App Optimization professionals often face challenges such as balancing user experience improvements with app performance, staying updated with rapidly changing app store algorithms, and interpreting large volumes of user data to inform decisions. Additionally, working cross-functionally with developers, designers, and marketers requires effective communication and negotiation to prioritize features and updates. It's also common to manage multiple testing cycles, analyze A/B test outcomes, and respond quickly to user feedback or technical issues. Overcoming these challenges requires adaptability, a proactive approach to learning, and strong analytical skills.

What are the key skills and qualifications needed to thrive in app optimization, and why are they important?

To excel in App Optimization, you need a solid understanding of mobile platforms, user experience (UX) design principles, and analytics, often supported by a relevant degree in computer science or a related field. Expertise with tools like Google Firebase, App Store Connect, A/B testing platforms, and analytics dashboards is commonly required, and certifications in app analytics or UX can be advantageous. Strong problem-solving skills, attention to detail, and the ability to collaborate across product, marketing, and development teams help you stand out. These skills ensure that apps achieve maximum performance, user retention, and competitive placement in app marketplaces.

Senior Software Engineer, App Performance

Roblox

San Mateo, CA

$139K - $183K/yr

Full-time

Re-posted 29 days ago

Job description

The Consumer App Foundation team is looking for a Senior Software Engineer to improve Roblox performance across our supported platforms. Our platform is used by over 150M people daily. You will work primarily in cross-platform C++ Roblox game engine code, partnering with teams across the company to identify bottlenecks, ship measurable improvements, and prevent regressions over time.

Our team is responsible for the end-to-end performance of the Roblox client on Android, iOS, macOS, Windows, Xbox, Playstation and TV. We tackle the platform's most difficult technical constraints, ranging from speed and responsiveness to efficiency and stability, to ensure a high-performance experience across all of our devices and platforms.

You will:

  • Own the end-to-end performance of the Roblox client across all platforms directly moving the needle on our key metrics: TTI, app size, battery usage and more.
  • Build the benchmarking, profiling, and telemetry systems required to catch regressions early and continue scaling our application even further.
  • Collaborate closely with stakeholders across Engineering, Product, and Design to evaluate technical tradeoffs, align on company-wide priorities, and execute smooth rollout plans.
  • Drive deep technical impact by diving into complex, unfamiliar codebases, taking ambitious projects from greenfield MVP to production-grade, and mentoring peers on performance best practices.

You have:

  • 3+ years of experience writing high-quality, performant C++ code in large, complex codebases
  • A proven track record of building reliable measurement, monitoring, or regression prevention systems.
  • The ability to autonomously navigate complex, ambiguous systems and deliver stable, production-grade software.
  • Exceptional communication skills to discuss technical trade-offs with both engineering peers and cross-functional partners.

Bonus:

  • Hands-on experience with on-device profiling (iOS and/or Android) to find and measure optimization opportunities.
