Job Specifications

Our Vision
We’re building the next-generation suite of ERP - an all-in-one finance platform serving mid-size to entreprise companies. We tackle a wide array of technical products ranging from banking connectivity, payment, AI, procurement.

The Dream Team Awaits :

Marion, Product (ex AirBnB, Luko, Facebook)
Joseph, our CTO and co-founder (ex BNP Paribas, Ministry Of Armed Forces, Luko)
Alexis, Tech (PhD, ex Ministry of Armed Forces, Luko)
Vahagn, Tech (ex Facebook)

Your mission:
Help build the next-generation ERP, create applications that help businesses scale and thrive.

We are building a strong culture on a foundation of shared values
Team-spirit: we empower, trust, respect & support each other. The team wins or loses together: We share successes and accept failure collectively without blaming individuals.
Humble & Accountable Owners : We are all owners - each project, roadmap item and OKR has an owner who is empowered. No one is too good to go in the trenches and execute. And with great powers come great responsibilities: we are accountable & responsible : i) we deliver what we commit to and understand that failure to do so has an impact on the team and ii) we are cautious with ressources and thrive to do more with less.
Radical candor & transparency: We take the time to provide candid and honest feedback as much as needed to be helpful and we receive feedback with a careful ear and an open mind and heart. The basic principe is that other people on the team always mean well, unless proven otherwise.
Focus & Simplify: we have limited output capacity and prioritize it carefully based on two dimensions i) what objectively creates more value for customers (current & future) in the handling of their treasury over the long term and ii) effort.
Build, Break, Learn, Fix, repeat : We value & encourage trying and thinking outside the box and accept that breaking is part of building. We are not scared of it but we own our mistakes, learn from them and improve over time.
