Summary

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

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

Background and experience

1. 3+ years of hands-on experience in Rust and/or C++ in production
2. Experience in modern C++ is a plus, especially for systems-level or low-latency work
3. Proven track record in building exchange connectivity:
4. Order entry APIs and lifecycle management
5. Market data handling, parsing, normalization, and distribution
6. Strong systems engineering fundamentals:
7. Concurrency, memory management, networking, serialization, and observability
8. Solid understanding of performance tuning and profiling in real-world systems
9. Experience with cloud-native deployment and operations in major clouds, e.g., AWS
10. Pragmatic approach to reliability and operability in live trading environments
11. Proactive mindset with strong problem-solving ability
12. Excellent communication and a collaborative mindset when working with trading, product, and engineering teams

Nice to have

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

How we work

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

Location and setup

1. Full-time role within Keyrock’s StratMM BU
2. Remote-first, hybrid-friendly, with close collaboration across engineering and trading
3. Europe Time Zone is preferred
