Restore technical leadership without becoming the bottleneck

In this scenario, a team maintains a B2B SaaS product built with Next.js and Node.js. Nearly every consequential topic goes to the same senior engineer: breaking down a feature, responding to an incident, choosing a dependency or balancing technical debt against a deadline.

Answers arrive late, PRs pile up and the team starts waiting for approval even on reversible choices. Before adding headcount, the first job is to identify what genuinely needs senior input and let the rest of the work move independently.

We trace two paths through the team: a feature that spans React, the API and the database, followed by a recent production incident. At every hand-off, we note where work stops, what information is missing and who gets pulled in. This reveals whether the blocker is a genuine skills gap or an implicit decision rule.

The assessment protects senior attention for work that needs it and gives the team clear boundaries for everything else.

Product intent, constraints and risk are made explicit before the team debates a solution. An escalation rule then sends the PR to a peer, the relevant domain owners or the Tech Lead. Hard-to-reverse choices are captured in an ADR; local implementation decisions stay in the PR.

The Tech Lead focuses on domain boundaries, high-risk changes and unresolved disagreements. The role should increase the team’s decision-making capacity, not create a new approval queue.

type ChangeRisk = 'local' | 'cross-domain' | 'high-impact'

export function reviewPolicyFor(risk: ChangeRisk) {
    if (risk === 'high-impact') {
        return { reviewers: 'tech-lead', minApprovals: 1 }
    }
    if (risk === 'cross-domain') {
        return { reviewers: 'domain-owners', minApprovals: 2 }
    }
    return { reviewers: 'peer', minApprovals: 1 }
}

The rule captures a team agreement: every PR gets reviewed, but not every change needs the same reviewer or the same level of scrutiny.

The engagement combines immediate problem-solving with deliberate knowledge transfer. Each decision handled with the team is documented so they can reuse the reasoning after the consultant leaves.

1. 01

   Make the work visible

   Group the roadmap by outcomes and risk, then surface the decisions that genuinely block delivery.

2. 02

   Unblock one end-to-end path

   Ship one feature across the stack to test scoping, review and deployment.

3. 03

   Set escalation thresholds

   Write down what the team handles alone and which situations need senior input.

4. 04

   Build ownership

   Pair an owner with a second engineer on sensitive domains, then rotate reviews.

5. 05

   Plan the exit

   Gradually reduce the consultant’s involvement, observe decisions made independently and refine the guardrails.

The pace depends on how quickly the team can take ownership. More ceremonies do not create autonomy on their own.

The team still asks for help when the risk warrants it, but people can explain that risk, involve the right owner and move ahead on reversible choices. Senior engineers recover time for the work where their experience and context matter most.
