Lifecycle · Turns a first order into a second

## About the role

You own retention as a number: the flows, the segments, and the experiments that turn a first order into a second. A technical role that's growth-led.

Most commerce growth hides in retention, and it's technical enough that a marketer can't own it alone. That system needs one owner, end to end. That's this role.

## What you'll do

-   Build and ship the flows, segments, and experiments across the lifecycle stack, yourself.
-   Model the customer's life after checkout: what actually predicts a second order, where the flows leak, what a segment is worth.
-   Read the data underneath Klaviyo and the rest, and trust it only after you've checked it.
-   Run retention experiments against a baseline, and kill the ones that don't move it.
-   Treat lifecycle as one system, not a folder of automations.
-   Report retention as a number the founder can act on, not a send report.

## What you'll own

Retention, as a number. The flows, the segments, and the experiments across the lifecycle stack, built and shipped by you. You're technical, but the job is growth-led: the question is never how many messages went out, it's whether more customers came back.

## Who you are

-   You've built lifecycle or CRM systems and got hooked on the experiment results more than the tooling.
-   You write real automation and you read your own data.
-   You'd rather move a retention curve than launch a campaign.

## Who this isn't for

If you measure the job in sends, campaigns, or how elaborate the flow diagram looks, we'll disagree about what done means. Volume isn't the point here.

## How we evaluate

Retention moved, against a baseline. Not messages sent.

## If this is your seat, show us the work.

Not a resume. One thing you made or moved that speaks to this role. We read every one, and we write back either way.
