• Optimize: Conduct deep-dive performance tuning, memory analysis, and kernel-level optimizations.
• Collaborate: Work within an Agile framework alongside cross-functional teams to translate business requirements into technical reality.
• Mentor: Share your expertise with the wider engineering community in Sri Lanka through code reviews and knowledge-sharing sessions.

• Academic Foundation: A Bachelor’s or Master’s degree in Computer Science, Engineering, or a related field.

• C++ Expertise: Strong proficiency in modern C++ (C++11/14/17/20) and a solid grasp of STL and Boost. Solid understanding of object lifetime, memory management, and ownership.

• System Knowledge: Familiarity with Linux/Unix environments, multithreading, concurrency, and real-time systems.
• Tooling: Experience with build and debug tools like CMake, GDB, Valgrind, Vtune, Git, ASAN/TSAN.
• Problem Solving: An analytical mindset capable of troubleshooting complex bottlenecks and system failures.

Why Connect Now?

• Skip the Line: When we open a role, candidates in our talent pool are prioritized for the final interview stages.
• Exclusive Insights: Receive updates on our technical roadmap and invites to our private tech meetups or webinars.
