Its solutions help organizations improve operational efficiency, optimize infrastructure utilization, and maintain reliable performance as their systems and workloads grow.\n\nThe product consists of multiple interconnected components responsible for data processing, system operations, and communication between services. The engineering environment involves solving complex technical challenges related to scalability, performance, concurrency, and resource efficiency.\n\nThe platform is continuously evolving, with a strong focus on improving existing capabilities, introducing new functionality, and maintaining high engineering standards.\n\nAbout the Role\n\nWe are looking for a Senior Software Engineer to join an experienced engineering team working on core components of a complex software platform.\n\nThis is a hands-on engineering position combining new feature development, system optimization, and long-term ownership of technically challenging components.\n\nYou will be involved throughout the full software development lifecycle, from analyzing requirements and designing solutions to implementation, testing, troubleshooting, and continuous improvement.\n\nThe role requires strong technical expertise, independent problem-solving, and the ability to make practical engineering decisions in an environment where performance, reliability, and maintainability are essential.\n\nYou will collaborate with experienced engineers across different technical areas, contribute to architectural discussions, and help improve the overall quality and efficiency of the platform.\n\nKey Responsibilities\n\nDesign, develop, and maintain complex, performance-critical software components.\n\nImplement new functionality and enhance existing platform capabilities.\n\nImprove system performance, scalability, and resource efficiency.\n\nWork on technical challenges involving concurrency, multithreading, and memory management.\n\nAnalyze system behavior, identify performance bottlenecks, and implement effective optimizations.\n\nInvestigate and resolve complex technical issues across interconnected components.\n\nEnsure high standards of code quality, reliability, maintainability, and test coverage.\n\nTake end-to-end ownership of engineering tasks, including technical design, implementation, validation, and ongoing support.\n\nParticipate in architectural discussions, technical design reviews, and code reviews.\n\nCollaborate with cross-functional engineering teams to deliver reliable and efficient solutions.\n\nContribute to knowledge sharing, technical guidance, and mentoring within the team.\n\nApply AI-assisted development tools where appropriate, critically evaluating generated solutions and ensuring engineering quality.\n\nRequired Competence and Skills\n\n7+ years of professional software engineering experience, preferably working on complex backend, infrastructure, or system-level software. Strong candidates with fewer years of experience may also be considered.\n\n3+ years of strong hands-on programming experience with C++. \n\nSolid understanding of concurrency, multithreading, synchronization, and memory management.\n\nStrong knowledge of performance optimization, profiling, debugging, and resource utilization.\n\nExperience developing and maintaining complex, performance-critical software applications.\n\nAbility to investigate technical problems across multiple components and identify root causes.\n\nExperience independently driving engineering tasks from technical design through implementation and validation.\n\nPractical experience with AI-assisted development tools beyond basic code completion, including evaluating and improving generated solutions.\n\nStrong analytical thinking, problem-solving abilities, and attention to engineering quality.\n\nGood communication skills, a collaborative mindset, and willingness to take long-term ownership of developed components.\n\nB.Sc. or M.Sc. in Computer Science, Software Engineering, or a related technical field\n\nNice to Have\n\nExperience with complex backend platforms or core infrastructure development.\n\nUnderstanding of distributed systems and large-scale software architectures.\n\nExperience with high-performance computing or resource-intensive applications.\n\nFamiliarity with C#,Java, Rust, Go\n\nExperience optimizing existing systems and improving their reliability and efficiency.\n\nWhy Us:\n\nWe provide 20 days of vacation leave per calendar year (plus official national holidays of a country you are based in).\n\nWe provide full accounting and legal support in all countries we operate.\n\nWe utilize a fully remote work model with a powerful workstation and co-working space in case you need it.","description_format":"text","description_chars":5167,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"Ukraine","iso":"UA","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-11-09T21:41:00Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring
