• Lead backend, DevOps, and CI/CD decision-making
• Embed AI into engineering workflows & ops
• Strong engineer with system engineering & system architectural experience; exceptional communicator across technical and non-technical audiences.

• Experience in high-availability, high-compliance environments
• Bonus: Fintech, Trading or Financial Services background.
• Extensive API experience
• Experience as a founding member (10th hire or less) of an engineering team that successfully scaled.
• Huge ownership: build core infra from scratch.
• Work with a high-caliber team, fast-paced and product-minded founders who have worked in some of the most recognised tech businesses in the world.
• Help define an open-source platform from day one.
• Clear path to tech unicorn status with fruitful equity included.
