Senior Engineer

Senior engineers earn respect by making work easier, safer, and more valuable for the team and company. Seniority requires creating lasting value, not only writing technically clean code. Senior engineering is measured by improving the surrounding team, systems, and decisions, not by coding speed alone. The practical standard for generated-code ownership is the ability to troubleshoot and repair failures. Code is valuable only when its long-term value exceeds its long-term cost. A marker of progress toward senior engineering is fully understanding LLM-generated code during review. Technical arguments are less likely to influence business decisions unless engineering quality is connected to money, time, and risk. Every line of code creates a maintenance obligation. Technical debt costs should be made visible when they cause bugs, slow delivery, increase support burden, block product changes, or create operational risk. A senior engineer's higher-value responsibility is to make others better rather than only produce features. Senior engineers must explain technical debt in business terms. Senior-level readiness includes being prepared to fix generated code during incidents.
