About the Role
~1 min readWe're seeking talented senior backend developers to join our team. You'll play a pivotal role in mentoring more junior developers, decision making on architecture, and contributing to our code base. Working in a scrum team alongside 6-8 engineers, a UX designer, and a Product Manager, you'll have autonomy to drive innovation in areas like social investment features, document and workflow management, products enhanced with AI, and legal template generation. Teams are managed from within and report directly to the Director of Engineering, so you'll be working alongside with your manager to solve technical problems.
This is a unique opportunity to gain extensive knowledge of the startup world, VC fundraising, investor tax schemes, and more. As you work on complex projects, you'll also gain invaluable domain knowledge that will prepare you for entrepreneurship yourself.
We're an international team of around 20+ developers from 12 countries based in the UK and France, with a hybrid working model that allows for flexibility and collaboration. While each team meets fortnightly at our offices near Old Street to whiteboard, plan, and socialise, you'll also have the freedom to work remotely.
