Founding Software / Platform Engineer

Stealth Fintech (London / Hybrid)

Up to £150,000 + Equity

I'm working with a stealth-mode startup that's building a GPU-backed trading platform, with the goal of making GPU trading efficient and unlocking price discovery in a completely new market. With strong interest from SF venture capitalists and a seed round expected to close next month, this is the chance to join at the most exciting stage of the journey.

The founding team already includes world-class talent from MIT, Caltech, Harvard, Citadel, and Meta. They're now looking for a Founding Engineer with pedigree from top-tier tech or fintech companies, someone who can both lead and build, and who will play a visible role in fundraising as proof of the company's ability to attract exceptional talent.

• Impact: Shape the architecture and scale of a trading platform in a completely new asset class.

• Visibility: Be part of the fundraising pitch and future public face of the company.

• Ownership: Drive technical decision-making across backend, infrastructure, and deployment.

• Growth: Join a team of proven founders with deep technical and financial expertise.

• Building and scaling a complex trading platform from the ground up.

• Improving and expanding cloud deployment processes (currently GCP).

• Leading on backend engineering in Python, with PostgreSQL for data storage.

• Expanding Terraform usage across deployments and managing Kubernetes clusters.

• Collaborating with the founding team on data acquisition, frontend, and platform scaling.

• Strong experience from a recognisable tech scale-up or fintech (e.g., Revolut, Spotify, Bloomberg, etc.).

• Track record of building complex systems - either in financial services, B2B SaaS, or other data-heavy domains.

• Hands-on with Python, Terraform, Kubernetes, and cloud (GCP preferred).

• Understanding of markets, trading systems, or brokerage platforms (Bloomberg, commodities, etc.) would be a big plus.

• Someone equally comfortable building as they are leading - you'll be in the trenches but also shaping the vision.

• Founding-level equity + salary.

• A central role in the fundraising journey and future company growth.

• Work alongside some of the brightest minds in finance, AI, and engineering.

• The chance to define an entirely new market.
