Senior/Staff Software Engineer, Sage

• You have professional experience working in complex backend systems: This usually means at least 7+ years of work experience, building (and sometimes breaking) within systems that grew and changed over time
• You understand systems, not just frameworks: You're comfortable in Linux/Unix environments well past the level of running commands you looked up. You've broken things, debugged them, and come out the other side understanding what happened
• You have real depth in at least one language (object-oriented or otherwise; Java, C++, Rust, Go, Python, and C# are all fine signals) with strong computing fundamentals and can reason about memory, concurrency, and performance at a lower level
• You have working knowledge of networking, enough to reason about what happens when a device drops offline mid-update, or why a connection is behaving strangely, without needing to look up the fundamentals first
• You're demonstrably curious, e.g. in side projects, open source contributions, a home lab, a technical hobby, or a history of teaching yourself things. We care less about the domain than that it exists
• You can hold complexity and still ship. You've led a technical effort, official title or not, from a fuzzy problem to a real outcome, and you know how to make tradeoffs under ambiguity
• Re: years of experience: we're not fixated on the number. We care about depth and range. Someone with 6 years of genuinely varied, hands-on systems work will often be a stronger fit than someone with 10 years in a narrow web stack. If you're unsure whether your background counts, apply anyway and let us figure that out together

Desirable

• Shape the architecture of a fleet of edge devices deployed in the physical world, and the cloud systems that orchestrate, monitor, and update them
• Dig into ambiguous, often novel problems (resident location modeling, fall detection, sensor fusion)
• Build the diagnostic tooling that lets us understand what's happening on hardware we can't just walk up to
• Get hands-on with remote troubleshooting when something breaks in the field, reasoning about network, hardware, and software all at once
• Work directly with other Sage teams to ship solutions end to end collaboratively
• Review code and run design discussions, and help less experienced engineers get better by through teaching and explaining
• Push back on us when there's a better way to build something; we'd rather be right than consistent
