Senior System Engineer

Company Description

Portofino Technologies is a start-up building high-frequency trading (HFT) grade technology for digital assets. 

Today, Portofino provides liquidity on the largest centralised and decentralised cryptocurrency exchanges and provides services to institutions and Web3 projects that require digital asset liquidity. 

Since our establishment in 2021, we have been building market-leading HFT technology to deploy our liquidity provisioning algorithms. Our competitive advantage is our superior proprietary technology that leverages advanced machine learning and stochastic control techniques to provide our clients and partners with the best pricing in the market. 

We are backed by some of the largest VCs in the world, Valar Ventures, Coatue, and Global Founders Capital. Our vision is to scale our technology across the full crypto infrastructure value chain.

Job Description

Scope of the role

At Portofino we build our distributed trading system on a in-house platform where we control with a very fine level of detail how the software is designed, built, runs, interacts with the operating system, the hardware, and various other services via a purpose-built network topology.

As a systems engineer, you’d be responsible for ensuring that our application framework, built in C++, integrates best with the infrastructure provisioned by the devops team, and that it is able to deliver on the various requirements of the software engineering teams in terms of latency, scalability, and reliability.
You’d be expected to have both broad and deep knowledge on a variety of highly technical topics with the ability to take control and enable the business to do things internally as needed instead of being constrained by the design of third-party solutions.
