This is a highly hands-on role. You will work directly with the founder and have significant influence over engineering execution, product quality, architecture, and release velocity. We value engineers who can independently move from: Problem → investigation → implementation → test → deployment → verification This position will begin as a contractor engagement with the potential to grow into a longer-term or full-time role based on performance, company growth, and mutual fit. We are looking for a builder who wants meaningful ownership—not someone waiting for perfectly defined tickets.
