The Position

OPSWAT is seeking a Lead LAMP Stack Developer to join our NetTAC team. This role primarily focuses on maintaining and enhancing our established LAMP-based frameworkβ€”utilizing Angular.js, PHP (~5.6), Symfony (3.4), and zendframework/zend-db (2.8)β€”while also developing smaller, targeted features to improve our Network Detection and Response (NDR) and network traffic analysis platform. Additionally, you will play a key role in transitioning our technology to a modern stack over the coming years.

What You Will Be Doing

  • Maintenance & Optimization: Oversee the daily maintenance of our existing LAMP stack, ensuring system stability, security, and performance.
  • Feature Enhancements: Develop and deploy incremental features that enhance platform functionality without disrupting the core system.
  • Front-End Management: Utilize Angular.js to maintain and improve the user interface, ensuring an intuitive and responsive experience for security professionals.
  • Backend Development: Work with PHP (~5.6) in conjunction with Symfony (3.4) and zendframework/zend-db (2.8) to support and enhance backend operations.
  • Cross-Functional Collaboration: Collaborate with UX designers, product managers, and backend engineers to align enhancements with overall product strategy.
  • Transition Strategy: Contribute to the roadmap and execution of a technology transition over the coming years to a modern tech stack, which will include React for front-end development; Kafka, Go, and Rust for backend services; and advanced data storage solutions such as Parquet, Iceberg, Postgres, and other NoSQL data stores.
  • Best Practices & Mentorship: Implement coding standards and best practices while mentoring junior developers on maintaining legacy systems and integrating new technologies.

What We Need from You

  • 7+ years of full-stack development experience
  • Proven expertise in Angular.js, PHP (~5.6), Symfony (3.4), and zendframework/zend-db (2.8) within a maintenance-driven environment.
  • Strong Linux system administration skills, including server management, security hardening, and performance tuning.
  • Proficiency in Bash shell scripting for automation and system maintenance tasks.
  • Experience with Python for scripting, automation, or backend service development.
  • Solid background in both front-end (HTML, CSS, JavaScript) and backend development.
  • A detail-oriented mindset with a proven track record in sustaining legacy systems while delivering targeted improvements.
  • Excellent communication skills and a collaborative approach to working across multiple teams.
  • Strong problem-solving skills with a focus on optimizing and securing existing infrastructures.

It Would Be Nice if You Had

  • Experience with maintaining and enhancing LAMP stack systems.
  • Experience in cybersecurity or network traffic analysis is highly desirable.
  • Experience in the network detection and response or cybersecurity sectors.
  • Familiarity with modern CI/CD pipelines and automated testing to support ongoing maintenance and feature integration.
  • A forward-thinking mindset with enthusiasm for transitioning to a modern technology stack including React, Kafka, Go, Rust, Parquet, Iceberg, Postgres, and other NoSQL data stores.
  • A passion for balancing system stability with innovative feature development and technology evolution.
