Why Senior Devs Should Mentor (And How It Benefits Your Team)

Why it matters

As a senior developer, your code output isn't the only thing that matters. What really takes you beyond "just a great coder" is your ability to help others grow. Mentorship is how you build a healthy, resilient team - and develop your own leadership skills in the process.

According to the author, their first internship at a small 10-person team had a huge impact. The generosity and patience of the senior engineers, especially one natural mentor, showed them the power of sharing knowledge. That experience stuck with them and later inspired them to formalize mentorship programs at their own companies.

Mentorship strengthens team culture, fosters collaboration, and scales institutional knowledge. The time you invest in helping others directly benefits your team through faster PR cycles, tighter feedback loops, and higher-quality output. It turns a collection of individuals into a cohesive, resilient unit.

Personally, mentoring also helps senior developers grow from being "great coders" to "great developers." It teaches you to break down complex ideas, develop empathy, recognize potential, give effective feedback, and flex your leadership muscles - even without a formal title.

Decision Framework

When it comes to mentorship vs. coaching, the author prefers the broader, more relational approach of mentorship over the goal-oriented, structured nature of coaching. Their goal is to help engineers develop their voice and context, not just hit short-term milestones.

The key differences:

• Coaching is focused and time-bound, with clear goals and metrics.
• Mentorship is broader and more relational, rooted in trust, curiosity, and long-term growth.

Trade-offs

Mentoring Junior Devs vs. Relying on AI

Pros of mentorship:

• Builds a healthy, diverse talent pipeline for the future
• Develops engineers who can apply AI tools with judgment and context
• Maintains institutional knowledge and team resilience as seniors move on

Cons of over-relying on AI:

• Cuts off the next generation of talent and diverse perspectives
• Loses the human element of learning, context, and growth between sessions
• Jeopardizes your team's long-term sustainability

Recommendation

For senior developers, mentorship should be a priority, not an afterthought. Even if it takes time and effort, the benefits to your team culture, collaboration, and long-term resilience far outweigh the costs.

If your company doesn't have a formal mentorship program, consider starting one. Advocate for junior engineering hires, even in the age of AI. And most importantly, take the time to pour into the next generation of talent - it's an investment that will pay dividends for your team and the industry as a whole.
