C++ Engineer (w/m/d) at smartclip Europe GmbHRequirementsPlease note that this position requires work authorization for Germany.Language: German - Fluent (C1), English - Fluent (C1)Your Skills Master C++: Understand how the compiler thinks. Leverage modern C++ and dominate memory layouts and cache hits. Live in Linux: Make the terminal your home. Use perf, gdb, valgrind, and strace as your primary weapons. Think Distributed: Build systems that live on more than one server. Understand why „distributed locks“ are usually a trap. Simplify the Web: Use HTTP, JSON, and XML as the efficient wrappers they should be for your high-performance logic. ActivitiesThe ChallengeImagine a system that must decide, in a fraction of a second, which ad to show to millions of users across the globe. Thousands of requests per second. Zero room for lag. One wrong pointer or a suboptimal lock, and the whole house of cards falls.This is our Ad Server. It’s written in C++, it’s lean, it’s mean, and it’s the heart of smartclip.Stop implementing boring features. Start architecting performance. We don’t want a coder; we want a Performance Architect. Look at a profiling report and see a puzzle to be solved. Treat std::vector with respect and know exactly when to deploy a custom allocator.Your Mission Fight Latency: Hunt for microseconds. Optimise the hot path of our ad-serving engine. Ensure our response times stay lightning-fast, even during peak traffic. Master the Distributed Chaos: Evolve our architecture on smartx to handle transnational scale. Tackle the CAP theorem in the real world, not in a textbook. Tame the Data: Architect how we use NoSQL to fetch complex targeting data without breaking our latency budget. Set the Standard: Stop following style guides – define them. Establish the C++ best practices that keep our codebase maintainable while pushing the hardware to its absolute limits. Team Ownership over tickets: You’re trusted with real responsibility, not just tasks. No unnecessary bureaucracy, no micromanagement – we rely on you to take things forward. Build > Talk: We test what works – not what sounds good. Fail fast, learn faster. High standards, low ego: We take our work seriously, but not ourselves. Direct feedback, honest collaboration, no drama. Stay sharp: Hackathons, conferences, community – we invest in your growth and keep you at the cutting edge. And yes – the fundamentals are covered too: 30 days of vacation + Dec 24 & 31 off, Smart Fridays (4 days week possible), mobility (Germany ticket & JobRad), sports & health offerings, mental health support, corporate benefits, RTL+ access, and more.
