The finance function is broken. Everyone building for it is boring.

Fast-growing multi-entity companies get two options: duct-tape a Frankenstack, or surrender to a corporate ERP and its consultant army. Both are bad. Both are beatable. Beating them loudly is this job.

Light is the AI-native financial platform for modern companies. Fast to implement, intuitive to use, smarter every month. We call it organic software. Legora, Lovable, and Fuse Energy run on it. Product ships something worth shouting about every single week.

What we don't have is someone making a ton of fucking noise about it.


THIS IS NOT A NORMAL PMM ROLE.

Most product marketing jobs are maintenance: keep the messaging tidy, brief the agency, update the deck. This is the opposite. This is a founding hire for someone slightly unhinged. A person who sees a feature ship on Tuesday and has a video, a teardown, and a take live by Tuesday, made entirely by them and their agents.

You'll make a 110-person company the loudest thing in finance software. The product backs it up. Your job is volume, reach, and repetition until every finance leader in Europe has an opinion about Light.


WHAT YOU'LL BE DOING.

You'll report to our VP Marketing and work shoulder-to-shoulder with Product. Nobody will check your copy before it ships. That should excite you, not scare you.


THE AI PART. READ THIS TWICE.

We don't want someone "comfortable with AI tools." We want someone whose AI usage is frankly a bit alarming.

You run agents you built yourself. Your prompt library is a product. You've automated the boring half of your own job and spent the freed-up hours making more noise. One person, the output of a ten-person team. It only works if AI is your default way of doing everything: research, drafts, video, versioning, distribution.

You'll get every tool we can buy and full permission to rebuild your workflow weekly. Just as Light gives finance teams superpowers, we expect you to be walking proof of what one person plus AI can do.


WHAT WE'LL ASK FOR.


THE GOOD STUFF.

๐Ÿข In-office, five days a week, high talent density.
๐Ÿ’ธ Competitive salary.
๐Ÿ 25 days annual leave plus public holidays.
๐Ÿš€ Shape a category from the inside, not market around it.
๐ŸŒ Regular travel to Copenhagen, Munich, NY, Paris and wherever the action is.
๐Ÿฅณ Off-sites twice a year. The last one was in Italy.


HOW TO APPLY.

Send the loudest thing you've made and the weirdest agent you've built. A generic AI-written cover letter with no craft behind the prompt will be obvious - and is its own kind of answer ----.

If this reads as too much: it is.

Light is an equal opportunity employer.
