Keyrock is expanding!

Keyrock was founded in 2017 and has quickly grown from 3 to over 60 people today, half of whom work remotely around the globe. As an industry recognised liquidity provider and market maker, Keyrock is a leading European creator of algorithmic trading technology in the digital asset space. With VC backing and a constantly expanding global client base, Keyrock is one of Belgium’s fastest-growing fintech companies.

We’re currently active on over 80 exchanges and count numerous marketplaces and asset issuers among our clients, including some of the best-known companies in the crypto space.

Keyrock's beating heart is its technical team filled with software engineers, digital scientists and PhDs, who themselves are supported by university professors, industry-leading experts and a strong management team. Over the years Keyrock has become a company that is both idealistic and practical.

We are looking for:

A backend developer to support the growth of our infrastructure and maintain, which is based on an exciting and constantly evolving technology stack. It currently includes Rust, Node.js, Python, PostgreSQL (TimescaleDB), Kubernetes and plenty more! Your mission would be to develop new features, integrate thirty party APIs, support the development of trading algorithms and propose improvements to our current infrastructure. An ideal candidate has experience in developing low-latency trading systems, is passionate about algo trading and crypto and is a  low-level system thinker.

Important: it is worth understanding that we are not a blockchain company, and as such, blockchain development experience is not significant nor sought after by us. Our software is blockchain agnostic and it could be deployed on any type of assets, not limited to blockchain-based assets. We do however welcome blockchain engineers, especially those passionate about trading, as it generally indicates passion for the industry, which we value.
