About Keyrock

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, Singapore and Paris, 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. Keyrock is looking to expand and establish itself as a full-service financial institution through both organic innovation and inorganic growth.

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

Keyrock's Strategic Market Making (StratMM) team is hiring a Rust Engineer to build and evolve our hybrid CEX/DEX exchange connectivity layer. You will own and manage our team's integration path for exchange venues, handling abstractions for execution logic and market data ingestion, while also exploring a low-lift integration model to enable rapid, cost-effective initial support for new trading venues with the flexibility to upgrade to more robust, permanent implementations later. This role collaborates closely with the trading desk, requiring a product-oriented mindset.

Job Description

Design, build, and maintain high-performance exchange connectivity for orders and market data across multiple venues
Work on connectivity to novel liquidity access platforms, such as intent-based venues
Deliver robust, observable services with clear SLAs and graceful failure modes
Optimize for latency, throughput, and stability in production environments
Collaborate regularly with traders, quants, and product teams to translate strategy needs into reliable systems
Establish strong testing, simulation, and replay workflows for fast and safe iteration
Champion code quality, observability, incident response, and performance profiling, embedding security at every stage.
Help shape technical standards and mentor teammates in a high-caliber engineering group

Background And Experience

3+ years of hands-on experience in Rust and/or C++ in production
Experience in modern C++ is a plus, especially for systems-level or low-latency work
Proven track record in building exchange connectivity:
Order entry APIs and lifecycle management
Market data handling, parsing, normalization, and distribution
Strong systems engineering fundamentals:
Concurrency, memory management, networking, serialization, and observability
Solid understanding of performance tuning and profiling in real-world systems
Experience with cloud-native deployment and operations in major clouds, e.g., AWS
Pragmatic approach to reliability and operability in live trading environments
Proactive mindset with strong problem-solving ability
Excellent communication and a collaborative mindset when working with trading, product, and engineering teams

Nice to have

Good working knowledge of Python and how it is used by quants
Exposure to hybrid or DeFi on-chain DEX connectivity, RPC providers, and MEV-aware workflows
Familiarity with intent-based frameworks and matching paradigms in crypto markets
Experience with FIX, WebSocket, gRPC, REST, custom binary protocols, or feed handlers
Knowledge of CI/CD for high-availability systems and a DevSecFinOps approach in the cloud
Experience with time-series data, event sourcing, and deterministic replays
A genuine passion for and deep interest in digital assets and crypto trading

How We Work

Impact-driven: small, experienced team with high ownership and short feedback loops
Production-first: rigorous testing, staged rollouts, and observability baked in
Partnership with trading: rapid iteration with tight alignment to strategy needs
Quality mindset: code reviews, benchmarks, and a post-incident learning culture

Location and setup
