This One Skill Signifies Seniority For Software Engineers
Published 9/3/2025
This episode explains what is arguably the best career advice you'll hear this week: the one skill that signifies seniority in software engineers is the ability to synthesise and optimise for multiple factors at once. Instead of focusing on a single factor, such as performance or maintainability, senior engineers identify and weigh the various trade-offs involved in any decision.
- Discover the key skill that distinguishes a senior engineer: It's the ability to synthesise multiple, competing factors—like performance, maintainability, cost, and time to market—rather than focusing on just one.
- Learn why single-factor thinking can hold you back: Junior engineers often optimise for what they know best or what is easiest to measure, which can harm the overall solution, the team, and their professional reputation.
- Understand how to demonstrate seniority in interviews and at work: You can show your maturity and wisdom by identifying the crucial trade-offs for any given problem, asking what factors need to be balanced, and exploring options that might satisfy multiple goals at once.
- Explore how to find better solutions by thinking in trade-offs: The goal isn't just to make sacrifices; often, the mark of a great senior engineer is finding a third option that effectively balances or optimises for multiple important factors simultaneously.
- Start practising this skill today: Challenge yourself to identify what you are giving up with any decision and consider factors you don't normally prioritise. Ask "What am I saying no to?" to develop this crucial skill.
