When a Tech Lead Gets Demoted: Lessons from a Sudden Promotion and Return to Coding

1. Suddenly Promoted to Manager

In March 2024, the author was called by the department director and asked to become the technical lead of a merchant backend system because the previous leader was leaving. Although excited, he felt scared because he had five years of experience but little management or product communication skills.

After a night of inner conflict, he accepted the role, believing that at 36 years old this might be his only chance to move up.

He celebrated the promotion with friends, convincing himself that taking the opportunity was the right thing to do.

2. Hard Work, Continuous Problems

The team consisted of seven members: two peers, three junior engineers, and two recent graduates. The two peers often resisted his decisions during architecture reviews, making him feel a lack of authority.

During the second half of the year, his subordinates caused three online incidents (one P1, others P2), prompting leadership to consider replacing him. He tried to learn from resources but still lacked a systematic approach.

Additionally, a senior employee resigned and complained to the director about his leadership, and a product manager, while outwardly cooperative, criticized his management and delivery quality behind his back.

3. Reverted to the Original Role

At the end of the month, the director asked about his impact on incident reduction, release efficiency, and core business metrics, to which he could only respond vaguely.

He was told a new manager would arrive, and he should return to development work, assisting the newcomer in getting up to speed.

Feeling his value diminishing and uncertain about future job prospects at 36, he reflected on the difficulty of staying in a role where he was demoted after a brief promotion.

4. Retrospective Summary

1. Rapid promotion without a “power buffer” – Organizations pushed a technical core into management without providing coaching or transitional support, turning the individual into a zero‑tolerance experiment where failures reflected system design flaws rather than personal ability.

2. Mistaking “leading the team” for “leading the code” – He applied linear coding thinking to non‑linear management problems, relying on overtime, heroics, and command‑style task assignment, neglecting the three‑step management lever of aligning goals, building trust, and sharing success.

3. Lack of quantifiable achievements – Without hard metrics such as incident‑rate reduction or release‑efficiency gains, he could not demonstrate ROI to senior leadership, leading to his rollback.

He also failed to provide a clear future plan for the team, which contributed to leadership’s decision to let him go. He hopes his story can serve as a reference for others’ growth.
