• Technologists passionate about adopting new tools and technologies — you actively explore emerging tech (AI agents, LLMs, novel dev tooling) and are excited to apply them to real-world engineering problems
• Natural problem solvers who thrive on complex technical challenges — whether it's shaving microseconds off latency, debugging a production crash under pressure, or architecting a system that scales globally
• Team players who love working with like-minded peers and are always looking to learn and improve
• Experience with making architectural recommendations on IT solutions, design & approach

 
WHAT YOU’LL GET
At Optiver, we have a very flat structure. We work extremely closely with our stakeholders, often working as a single team to solve Optiver’s problems. Individually, you are very highly empowered to deliver significant changes, with the support of your team and your leaders.
