You like understanding how things actually work in production and improving them where they break, slow down, or create noise. You have a done a similar job for at least 5 years. You are comfortable working close to operations. You do not need everything fully specified upfront, and you are able to translate practical SOC needs into technical solutions that hold up under pressure. You take ownership of what you build and feel responsible for keeping it understandable, maintainable, and secure. You communicate clearly with analysts and engineers, make pragmatic choices, and focus on outcomes rather than theoretical perfection. Why Northwave At Northwave, this role sits close to real security operations. The systems you build are used daily by SOC analysts and directly affect how incidents are detected, escalated, and resolved. You are not building demos or side projects. You are improving a production SOC stack that protects real organizations. Decisions are made quickly, technical input is taken seriously, and improvements are implemented rather than parked on a roadmap. You work with experienced professionals in an environment that values competence, responsibility, and getting things right.
