Job Description
Founding Engineer
Have you ever heard it said that the people who actually make money during a gold rush are the ones selling spades? This role may well be equivalent in the current AI boom.
If you opened LinkedIn or any social media platform at any point in the last 6 months, you would see that there are a lot of businesses currently building AI agents. This with the vocal and enthusiastic backing of VC funds across the US and Europe.
Fewer people have considered how these agents will get paid or how customers will track what they are paying for. Certainly, there are people working on the problem, though, and this small team of two founders and one existing engineer are among those people.
This founding engineer role would see you join an existing team of three people who are building a system to solve this problem. They are still in stealth mode and they have a lot of hard problems to figure out.
These problems mainly stem from their goal to be the the revenue infrastructure of choice for agentic payments—providing not just analytics, but intelligent systems that learn, adapt, and make every agent economically transparent both to the people who built them as well as the people who are paying for their work.
Our first placement is two months into his new role and he is loving it. Specifically he enjoys working with the two founders, appreciates the autonomy they have given him, and constantly finds himself adding new things to the list of things he needs to learn about.
Some questions you might have;
What is the tech stack? AWS, Python, TypeScript and React
Where am I most needed right now? Backend and infrastructure (any ML Ops experience a massive bonus.
Where is the office and how much time would I spend there? London Bridge. 4 days in person.
How much does it pay? Up to £ 100,000 + Equity
If you have read this far and feel like you are looking for this kind of challenge and specifically want to be part of the founding team of a small start-up up then please apply as follows:
Send your CV (or LinkedIn profile if you don’t have one) to putting “Ace of Spades” in the subject line. Include 2 or 3 lines written in your own words as to why you think this should be your next role. Any CVs received this way are guaranteed feedback. Any applications through LinkedIn are not. Sorry there are only so many hours in the day.
