Your work will involve improving a complex codebase, researching new code-hardening techniques, and solving challenging engineering problems where security, performance, compatibility, and binary impact all matter.\nAs one of our first engineers in Singapore, you will help establish and shape our local R&D presence alongside newly hired engineers and experienced colleagues relocating from our headquarters in Leuven.\nUp to 50% of your role will focus on R&D Customer Support. This is not traditional helpdesk support: you will investigate, reproduce, and debug complex technical issues while working closely with customers and internal engineering teams to find robust solutions.\nYou will report to the local Managing Director for office-related matters and functionally to your R&D Team Lead for technical priorities, guidance, and professional development.\nWhat You’ll Work On\nDevelop and improve our C++/LLVM-based products.\nResearch, test, and implement new functionalities and code-hardening techniques.\nWork with compiler internals, LLVM tools and libraries, and complex application-processing pipelines.\nMaintain and continuously improve a large, mature codebase.\nInvestigate, reproduce, and debug complex technical issues.\nHelp customers integrate and use our software successfully.\nCollaborate with customers and internal R&D teams to solve challenging engineering problems.\nImprove software quality through extensive testing.\nStay ahead of developments in compiler technology, mobile application security, and reverse engineering.\nWhat You Bring\nMaster’s degree in Computer Science or a related field.\nAt least 2-3 years of relevant software engineering experience.\nExcellent C++ skills.\nExperience working with large or complex codebases.\nKnowledge of compiler internals.\nFamiliarity with LLVM tools and libraries.\nExperience with low-level programming and debugging.\nStrong analytical and problem-solving skills.\nThe ability to communicate complex technical topics clearly and collaborate directly with customers.\nAn interest in software security and reverse engineering.\nWhy Guardsquare?\nThis is not standard application development.\nYou will work at the intersection of compiler engineering, low-level programming, mobile security, and reverse engineering. You will solve real-world LLVM challenges, explore mobile technology stacks beyond the application layer, and help shape the products, features, and engineering practices you work with.\nThe technology you develop can quickly make its way into industry-leading mobile applications used by some of the world’s largest payment providers, banks, and social media companies.\nWe offer:\nA full-time, office-based position in our new Singapore office.\nChallenging engineering work at the forefront of software protection and reverse engineering.\nReal-world problems that will expand your C++ and LLVM expertise.\nThe opportunity to help build a new R&D team from its early stages.\nAn international environment focused on technical ownership, collaboration, and continuous learning.\nThe ability to share your ideas and turn them into working solutions.\nAt Guardsquare, we bring together colleagues from many different backgrounds and nationalities. We value open technical discussion, different perspectives, knowledge sharing, and continuous growth.\nCandidates must be legally authorized to work in Singapore at the time of application (Citizen, PR or EP). \nReady to make software significantly harder to reverse engineer? Join us.\nApply by completing the application form below.\nAbout Guardsquare\nGuardsquare offers the most complete approach to mobile application security on the market, delivering the highest level of protection, with ease.
