What Bits Is

of thousands of paying members, and is run by a team of fewer than 20 people. Every engineer

works with Claude

The job

You own the code that moves the money: subscriptions and billing on Stripe (two accounts), the card with our card

processor, the store and gift cards, pushes to members, the reporting data behind them, and our USA site. You take

over these systems and make them better. You work beside our lead backend engineer, w

ho owns payments, Stripe,

infrastructure and the web today, and directly with the CEO.

Your first 90 days

• Take over the subscription, billing and store services end to end, with a writtenmap of what runs where, whatalarms exist, and what fails silently today
• Ship the top change the CEO picks
• Take one job a person does by hand today, in finance, support or collections, and automate it
  
  

How We Work

A small, excellent team, paid well on standard terms. No custom deals and no managers for their own sake.Smart people get a mandate, not instructions.

You get the problem and you own the answer.n estimate before anything starts, and the work fits the time agreed.You test it and read every word before it ships.

"It should work" is not done.S hip small, measure, then decide. Something customers can see every week.

One source of truth per topic, written down.

Manual work is never a reason not to do something. We automate it.

Fewer cancellations, more revenue and less bad debt come first. Anything that moves none of them waits.
