About the Role
As a Senior Software Developer, you will join a talented engineering team working on one of the world’s largest platforms, serving billions of daily impressions. This is a senior-level Individual Contributor (IC) role focused on hands-on software engineering, technical ownership, and delivering complex solutions. While the role involves mentoring and supporting other developers, it does not include direct people management responsibilities. The successful candidate is expected to demonstrate strong technical autonomy, take ownership of key components, and contribute to architectural and engineering decisions.
You will play a key role in designing, developing, and maintaining scalable, high-performance applications and services. Working across PHP, JavaScript, and modern backend and frontend technologies, you will contribute to complex engineering challenges involving large-scale data processing, distributed systems, and real-time applications.
We are looking for a strong engineering professional who combines deep technical expertise with a proactive approach to problem-solving and practical experience leveraging AI tools to improve software development workflows. What You’ll Be Doing Architect, develop, and maintain scalable applications, microservices, and APIs, primarily using PHP and the Laravel framework. Work with JavaScript and modern frontend technologies to build and maintain high-quality, responsive, and efficient applications. Leverage backend technologies to support real-time data processing and high-volume, secure data pipelines. Design and optimize solutions involving caching mechanisms, messaging queues, databases, and internal and third-party integrations. Ensure application performance, scalability, security, and maintainability across complex systems. Apply modern AI-powered development tools to accelerate coding, debugging, testing, code reviews, and problem-solving. Take ownership of technical components and domain knowledge, ensuring high-quality implementation and long-term maintainability. Contribute to architectural decisions, technical discussions, and engineering best practices. Support and mentor junior and intermediate developers through knowledge sharing, pull requests, and code reviews. Help foster a culture of continuous learning, collaboration, and technical excellence.
