Quant Trading / Digital Assets | Fully Remote | B2B Contract
I'm working with an early-stage quantitative trading firm looking for a

Senior AWS Infrastructure Engineer

to take ownership of its high-performance cloud infrastructure.
This isn't a traditional DevOps position. They need someone who understands how to build and optimise AWS infrastructure for

latency-sensitive, high-performance compute workloads , while also keeping a close eye on

AWS cost optimisation .
What they're looking for:
Experience supporting

low-latency / high-performance compute (HPC)

workloads
Strong understanding of compute and networking performance
Ability to identify and resolve infrastructure bottlenecks
Proven experience with

AWS cost optimisation / FinOps
Comfortable making architecture decisions and owning infrastructure end-to-end
Trading, HFT, electronic trading or digital-assets experience would be highly relevant
This is a

fully remote B2B contract

with a small, highly technical team building within the quantitative/digital-assets space.
If your background sits at the intersection of

AWS + low latency/HPC + performance + cost optimisation , I'd be interested in speaking.
