About Meta
Equal Employment Opportunity
π― Who is this job for?
This position is ideal for a Senior Infrastructure Software Engineer with 6+ years of experience in building large-scale, high-performance systems. It suits someone skilled in backend and systems programming (C/C++, Java, Python, JavaScript, Hack) with a strong grasp of API design, scalability, and system architecture. The role requires leading technical direction, optimizing infrastructure performance, and driving cross-functional projects, making it a great fit for engineers experienced in ownership of complex systems and large-scale application platforms.
π¬ Potential Interview Questions
1. Can you describe your experience designing and maintaining large-scale infrastructure systems?
I have built and optimized distributed systems handling millions of requests per day, focusing on scalability, latency reduction, and fault tolerance. I use monitoring tools and performance profiling to continuously improve system stability and throughput.
2. How do you approach optimizing code for efficiency and scalability?
I profile performance bottlenecks, refactor code with efficient algorithms and data structures, use caching where appropriate, and design asynchronous workflows to reduce blocking. I also ensure proper load balancing and horizontal scaling.
3. What programming languages are you most proficient in, and how have you applied them in infrastructure projects?
I am most proficient in C++, Python, and Java. C++ for high-performance, low-level components, Python for automation, tooling, and scripting, and Java for backend services in large distributed systems.
4. How do you ensure maintainability and testability in your codebase?
I follow clean architecture principles, modularize code, enforce strong typing where possible, and write unit and integration tests. I also use CI/CD pipelines to automate testing and deployment.
5. Can you describe a time when you identified and resolved a major performance issue?
On one project, I noticed high database latency due to inefficient queries. I redesigned the schema, added proper indexing, and introduced caching. This reduced response times by over 60% and significantly improved user experience.
6. What experience do you have with API design?
I design REST and gRPC APIs with clear versioning, well-defined contracts, and comprehensive documentation. I focus on ensuring backward compatibility and ease of integration for client teams.
7. How do you handle system monitoring and reliability?
I set up metrics collection with Prometheus/Datadog, establish alerting thresholds, and use distributed tracing for debugging. I also implement automated rollback strategies and chaos testing to ensure resilience.
8. Can you explain your experience with scripting languages like Python or JavaScript in infrastructure work?
I use Python extensively for deployment automation, CI/CD pipelines, and data processing. JavaScript has been used mainly for internal dashboards and monitoring tools.
9. How do you collaborate across teams to drive infrastructure improvements?
I run technical design reviews, document architectural decisions, and align priorities with product and operations teams. I encourage open communication and consensus-driven decision-making.
10. What’s your approach to leading complex technical initiatives?
I start with requirement gathering, propose architectural solutions, validate them with prototypes, and break them into milestones. I ensure alignment across stakeholders and guide the team through execution with regular checkpoints.
