Backend Rust Engineer - Options Trading

Since our beginnings in 2017, we've grown to be a leading change‑maker in the digital asset space, renowned for our partnerships and innovation.

Today, we rock with over 200 team members around the world. Our diverse team hails from 42 nationalities, with backgrounds ranging from DeFi natives to PhDs. Predominantly remote, we have hubs in London, Brussels and Singapore, and host regular online and offline hangouts to keep the crew tight.

We are trading on more than 80 exchanges, and working with a wide array of asset issuers. As a well‑established market maker, our distinctive expertise led us to expand rapidly. Today, our services span market making, options trading, high‑frequency trading, OTC, and DeFi trading desks.

But we’re more than a service provider. We’re an initiator. We're pioneers in adopting the Rust Development language for our algorithmic trading, and champions of its use in the industry. We support the growth of Web3 startups through our Accelerator Program. We upgrade ecosystems by injecting liquidity into promising DeFi, RWA, and NFT protocols. And we push the industry's progress with our research and governance initiatives.

At Keyrock, we're not just envisioning the future of digital assets. We're actively building it.

Mission statement

We are looking for a Rust OR C++ Engineer with extensive (HFT) Trading Systems experience, to join our team. As our technology is based on Rust (backend), typescript (UI), and Python (data), the ideal candidate must be willing to learn and become an expert in RUST, if not already proficient. We are open to candidates from C++/C backgrounds as well.

You will be joining our small but rapidly growing Options Business Unit’s fully remote engineering team, building out and improving our low‑latency options trading system.

• Pragmatic in their approach to problem solving through iterations, balancing business requirements with a long‑term technical vision.
• Complete ownership from gathering initial requirements all the way to deployment.
• Operational mindset, understanding infrastructure and deployments.

Background and experience

• Expert low latency and/or data heavy (trading) systems or similar (5+ years experience).
• Very strong experience with either Rust and/or C/C++.
• Willingness to become an expert in Rust (if not already).
• Experience with unit and integration testing, or equivalent functional testing approaches.
• Options Trading knowledge or a keen interest is considered essential.
• Previous experience with exchange connectivity and/or FPGA technologies is valuable.
• Experience with PostgreSQL databases and protobuf‑based protocols, or similar technologies, is considered essential.

Competences and personality

• Problem solving and pragmatic approach to system design and implementation.
• Entrepreneurial, “big picture” architectural thinking, with attention to detail.
• Excellent communication skills with a team player mindset collaborating within a fully remote global team.
