Company Overview

Digital asset market maker founded in 2017 with over 200 team members across 42 nationalities.
Active across 80+ exchanges offering market making, options trading, high-frequency trading, OTC, and DeFi trading desks.
Global remote workforce with physical hubs in London, Brussels, Singapore, and Paris.

Role Overview

Senior individual contributor role within the core Capital Markets division responsible for high-impact trading infrastructure.
Focuses on architectural ownership, performance optimization, exchange connectivity, and system resilience for mission-critical trading components.

Key Responsibilities

Design, develop, and optimize low-latency, mission-critical trading systems.
Own key trading stack components end-to-end (from architecture through production operation).
Collaborate with quants, traders, and engineers to enhance trading performance and resilience.
Maintain and evolve trading infrastructure with a focus on performance, stability, observability, and operational excellence.
Troubleshoot complex production issues across exchange connectivity, execution, and market data handling.
Drive engineering standards through technical leadership, code reviews, and mentoring.
Implement agentic engineering principles: leverage AI-assisted workflows, automate operational tasks, and evolve agentic tooling.
Contribute to functional, component, and production-readiness testing for critical trading components.

Requirements

Technical Skills:

Production-grade Rust experience building high-performance, concurrent systems (proficiency with Tokio is a strong advantage).
Hands-on experience in a systematic trading environment (HFT, Market Making, Quantitative Trading, or similar) with solid understanding of execution, market data, and operational risk.
Strong AWS and Linux expertise, including cloud infrastructure trade-offs for latency-sensitive workloads, shell scripting, debugging, and production troubleshooting.
Proficiency in Python or other scripting languages for strategy development, automation, and operational tooling.
Deep familiarity with trading system protocols (FIX, REST, WebSocket), exchange connectivity, and market data feeds.
Solid grasp of low-latency networking: TCP/UDP, packet and latency path analysis, dedicated network infrastructure, and kernel bypass techniques (DPDK).
Familiarity with agentic engineering tools and concepts: LLMs, MCP APIs, AI-first IDEs (e.g., Cursor, Claude Code), harness engineering, and workflow automation.
Ability to make sound architectural decisions, articulate trade-offs clearly, and guide implementation across complex systems.

Competencies & Seniority:

End-to-end ownership, reliability, and operational diligence.
Independent technical leadership, problem-solving, and mentoring ability.
Strong communication skills in a distributed, fully remote global team setting.

Compensation & Benefits

Competitive salary package.
Remote working model with flexible working hours.
Collaborative international team culture.
