Mairit · For engineering teams

Your AI is shipping code. Make sure a senior engineer signed it off.

Mairit plugs into Claude Code, Cursor, Copilot, and OpenClaw and routes pull requests, infrastructure changes, and migrations to a qualified senior engineer before they merge. Internal staff and principals first. Specialists when domain expertise is needed. Audit trail that holds up to SOC 2, your CTO, and your next postmortem.

The problem

AI is shipping code faster than your senior engineers can review it.

Your engineering team rolled out AI coding agents this year. Productivity went up. So did the volume of code reaching production with no human eyes on it. Most PRs are fine. The ones that aren't break in production at 2am.

01

AI-generated PRs are up 10x. Senior review isn't.

Pull requests written by Cursor. Migrations drafted by Claude Code. Infrastructure changes scaffolded by Copilot. Merged in minutes. Deployed in hours. Rolled back at 2am when the refund flow double-charges 10,000 customers.

02

Your staff and principal engineers are the safety net. They know it.

The staff engineer catching the missing transaction boundary. The principal noticing the AI rewrote auth in a way that bypasses the rate limiter. The senior who realises the migration drops a column the analytics team still uses. They don't have the cycles to review every PR. The volume forces triage. Some critical changes get a quick LGTM. Some get no review at all.

03

Your SOC 2 audit and your incident postmortem ask the same question.

Who reviewed and approved this change before it hit production? SOC 2 CC8.1 requires a documented change management process. Your incident response playbook starts with the same question. Right now, your evidence of senior review on AI-generated PRs is the GitHub approve button clicked by whoever was online. That's not going to hold up to your auditor. Or to your customer when their data leaks.

How it works

The review gate, inside your agent.

One command. The right reviewer. Reviewed code back in minutes. No more chasing reviewers in Slack, no more rubber-stamp approvals, no more 2am rollbacks.

1

AI finishes the work

An AI-generated PR. A migration. An infra change. A refactor. Something that would normally sit in the queue waiting for a reviewer who has 47 other PRs to look at.

Today vs. with Mairit

What merging an AI-generated PR looks like today vs. with Mairit.

Same payments PR. Two paths to the on-call rotation.

Today
  • 01Merge as-is. Hope the refund flow doesn't double-charge.
  • 02Staff engineer rewrites half of it. 2 hours per PR.
  • 03Slack the principal for review. Wait two days.
  • 042am page. Rollback. Postmortem next week.
With Mairit
  • Type /review. Pick a reviewer.
  • 26 minutes later, reviewed PR in the agent.
  • Staff engineer sign-off, cryptographically attested.
  • Full audit trail. Author, reviewer, on-call, and CTO all sleeping.
Use cases

Three motions at launch. The ones where getting it wrong wakes someone up at 2am.

Production code. Migrations. Infrastructure changes. The engineering work that needs senior review before it merges.

The PRs your AI agents ship. The ones your on-call has to defend.

Your engineers ship PRs at 5x the previous rate with Claude Code, Cursor, and Copilot. Today senior review happens when the staff engineer happens to be online. With Mairit, every AI-generated PR routes to a senior for a structured review on correctness, security, blast radius, and rollback before merge. Concurrency bugs flagged. Auth bypasses caught. Migration risks surfaced. Merged with an audit trail your CTO can put in front of an auditor.

  • Production PRs, hot-path changes, security-touching code, multi-service changes
  • Senior engineer sign-off in 25 minutes, not 2 days of waiting
  • Built on your firm's review checklist, your service criticality tiers, and your runbook

Sample review · PR-2841 payments refund flow, AI-generated
⚠ ConcurrencyRefund handler missing transaction boundary. Concurrent refunds can double-charge. Wrap in DB transaction.
⚠ IdempotencyNo idempotency key check before refund issuance. Retried webhooks will double-refund.
NoteTest coverage for refund happy path is good. Add tests for concurrent and retry cases.
✓ ApprovedAfter transaction boundary added and idempotency key check restored. Tests added.

The migrations your AI drafts. The ones a Sunday outage undoes.

Schema changes. Backfills. Data migrations. The AI is great at writing them. Terrible at knowing which downstream service still reads that column, what the analytics team built on top of it, and which midnight job will fail spectacularly. Mairit puts a senior engineer with the dependency map between the AI draft and the production database.

  • Schema changes, data migrations, backfills, index changes
  • Downstream impact analysis built into the review rubric
  • Rollback strategy verified before merge, not after the outage

Sample review · DB migration, drop legacy_user_id column
⚠ Downstream impactAnalytics ETL job reads legacy_user_id at 03:00 UTC. Will fail next night. Update or delay.
⚠ Rollback strategyMigration is destructive. No backup of column data. Add export step before drop.
NoteApplication code already migrated. No app-level dependency.
✓ ApprovedAfter ETL job updated and column data export added to migration. Coordinated with data team.

The infra changes your AI scaffolds. The ones that take down your prod environment when they're wrong.

Terraform changes. Kubernetes manifests. IAM policy updates. CI/CD pipeline tweaks. AI is fluent in the syntax. AI doesn't know your blast radius. Mairit routes infra changes to a senior who does. Reviewed against your environment topology, your security policies, and your incident history.

  • Terraform, Kubernetes, IAM, CI/CD, network and security configurations
  • Blast radius and rollback complexity scored automatically
  • Security-policy compliance check built into every review

Sample review · IAM policy update, expand S3 access for analytics service
⚠ Over-permissionPolicy grants s3:* across all buckets. Analytics needs read-only on two specific buckets. Tighten.
⚠ Drift from baselineDoesn't match firm's IAM baseline policy template. CI policy-as-code check would have failed.
NoteTime-bound access not requested. Consider 30-day review cadence.
✓ ApprovedAfter policy tightened to read-only on named buckets. Added to quarterly access review.
Built for the engineering stack

The review infrastructure your team has been quietly asking for.

MCP-native. Directory-aware. Attested. Built for the work your team actually produces.

Routing

Your staff engineers first. Domain specialists when yours can't cover.

Mairit reads your engineering directory and knows which of your senior engineers own which services, which domains, and which on-call rotations. They're the default reviewers. When nobody internal fits, or they're not available, Mairit falls back to a curated network of senior engineers across payments, security, distributed systems, and infrastructure.

  • Service ownership, domain expertise, and on-call status tracked at the directory level
  • Matching is explained, not black-boxed. You always see why
  • 100+ vetted senior engineers across payments, security, distributed systems, and infra

Rubrics

Structured checks. Not LGTM-and-merge.

Reviewers don't write three paragraphs of free-text. They answer a rubric built for the specific motion. 18 questions for a production PR. 14 for a migration. 16 for an infra change. Faster for them. Consistent across the team. Defensible at SOC 2 audit.

  • Rubrics designed with staff and principal engineers across payments, infra, security, and distributed systems
  • Review time typically 20 to 30 minutes, not 2 hours of free-form code review
  • Free-text notes stay where engineering judgment actually needs them
Production PR rubric
  • Correctness (concurrency, idempotency)
  • Security (authn, authz, secrets)
  • Blast radius and rollback strategy
  • Test coverage on critical paths
  • Observability (metrics, logs, traces)
  • Performance regression risk
  • 12 more...
Attestation

Every PR, signed. Every merge, logged.

When a senior engineer attests, it's cryptographically bound to their identity, their service ownership, and the timestamp. Every material action produces an immutable audit record. When your auditor or your incident response lead asks who reviewed what and when, you export the answer in one click. In a format that maps to SOC 2 CC8.1 change management and your incident review template.

  • Cryptographic attestation tied to a named, on-call senior engineer
  • Tamper-evident audit log, integrated with your Git history
  • SOC 2 CC8.1 and incident-postmortem export templates included

The review layer for your AI-generated code. Pilot in 30 days.

Pick one motion. Plug into Cursor, Claude Code, or your AI agent. See whether senior-grade review at machine speed actually changes how your engineering org ships.

The pilot

  • Pick one motion. Production PRs, migrations, or infra changes.
  • Plug in. Works with the AI tools your team uses today via MCP. No GitHub migration.
  • Internal-first routing. Your senior engineers review by default. Mairit network fills gaps.
  • 30-day outcome pack. Defect-rate change, audit-ready documentation, and a clear go or no-go on rollout.

Who this is for

CTOs and engineering leaders who'd rather have the change-management trail in place before the auditor asks for it.

  • Engineering teams at mid-market companies (50+ engineers) and AI-native scale-ups.
  • Teams already using AI agents heavily. At least one of: Claude Code, Cursor, Copilot, OpenClaw, or another MCP-native agent.
  • Audited, regulated, or customer-trust-critical. SOC 2 / ISO 27001 / PCI DSS / HIPAA-scoped, or running production payment, health, or financial systems.
