You are at your best when performance, memory safety and precise control over system behaviour all matter. You will improve core components, remove bottlenecks and introduce safer patterns without sacrificing throughput. Technical choices are expected to be explained in terms of maintainability, reliability and the people who use the product. Decisions should be recorded clearly enough that another engineer can understand the tradeoff months later. As a senior colleague, you will own substantial outcomes and help others make stronger decisions. You are expected to recognise risk early, communicate it without drama and move work forward with practical alternatives. Profile CPU, memory, allocation and IO behaviour. Design safe interfaces across language and process boundaries. Improve concurrency, scheduling and backpressure mechanisms. Build benchmarks and regression tests around critical paths. Review low level designs and support production investigations. Ability to reason about performance using evidence. Understanding of network or storage intensive systems. Experience that would add value

Kernel, driver or eBPF experience. High frequency, media, database or networking systems. Formal methods or safety critical development. A background that can succeed here

You may have worked on databases, compilers, game engines, telecom infrastructure, cybersecurity agents or industrial platforms. We value engineers who can zoom from an instruction level problem to the architecture that created it. What makes the opportunity interesting

The role combines intellectual depth with production impact. You will have access to meaningful workloads, experienced peers and technical decisions where careful low level work produces visible results. Nordic Investin will make sure you understand the context, expectations and decision path before you are asked to commit significant time. You do not need every optional technology if your core experience transfers and you can explain how you would close the gap. Nordic Investin welcomes candidates with different routes into technology and assesses applicants on relevant capability, judgement and potential.
