Principal Software Engineer

We are looking for a deeply hands-on Principal Software Engineer to be the most senior technical individual contributor at Hi Rasmus. Reporting to our Director of Engineering, this is a role on our Principal track, a craft career path that sits alongside the management track rather than beneath it. Where a Lead Software Engineer is the strongest technical contributor within one outcome team, the Principal Software Engineer works across all of them. You will help shape and evolve our platform architecture, strengthen shared technical practices, mentor Senior and Lead Engineers, and take on complex challenges that span teams or domains. This is not an advisory role. You will work alongside teams in the code, helping solve difficult problems and piloting new tools, patterns, and practices through real work. Your goal is not to become a permanent escalation point, but to leave teams more capable of making strong technical decisions independently.
