Job Description
Senior Backend Engineer, Rust/C++
MLabs
• Design, develop, and maintain core backend systems powering high-throughput trading, exchange, and network infrastructure using clean, efficient, and maintainable code. • Index on-chain data into event queues and persistence layers to serve WebSockets and scalable APIs consumed by user interfaces and risk dashboards. • Define the high-level backend structure, data flow, and interactions between components, focusing on event-driven architecture and messaging patterns common in financial systems. • Ensure architectural designs meet strict performance, high availability, and reliability standards. • Implement failover mechanisms, redundancy strategies, and disaster recovery plans to minimize potential downtime. • Implement and maintain robust security measures to protect backend infrastructure and APIs against DDoS attacks, data breaches, injection vulnerabilities, and other threat vectors. • Define data storage strategies and select appropriate databases and models tailored for financial applications. • Evaluate trade-offs across relational databases, key-value stores, and messaging queues. • Develop and execute a comprehensive testing strategy covering unit, integration, security, load, and performance testing. • Collaborate with the broader engineering team to establish test reporting and maintain standardized testing processes. • Stay informed on emerging backend technologies, evaluating new tools, frameworks, and methodologies to elevate system performance and scalability. • Document architectural designs clearly for both technical team members and non-technical stakeholders. • Participate in code reviews, mentor engineering team members, and enforce coding standards and best practices. • Collaborate closely with cross-functional teams, including on-chain engineers, frontend developers, product managers, quantitative specialists, and executive leadership.
Job Requirements
- Experience: 8+ years of backend engineering experience within the financial services industry.
- Core Languages: 6+ years of hands-on experience using Rust or C++ to build highly scalable web services.
- Concurrency: Mastery of asynchronous programming and advanced concurrency patterns, with an emphasis on thread safety and lock-free data structures.

- Communication: Excellent verbal and written communication skills with the ability to work effectively in a collaborative, remote environment.
- Preferred Qualifications:
- Experience with low-level network programming, including asynchronous I/O, direct socket programming, and Linux kernel optimizations (e.g., epoll, zero-copy, or kernel bypass techniques).
- Hands-on experience fine-tuning latency-sensitive components in trading systems, such as order-matching engines and risk engines.
- Familiarity with blockchain technology, smart contracts, and decentralized systems.
- Fundamental understanding of finance and derivatives trading.
- Ideal Profile Fit:
- Comfort operating within a compact, agile team navigating complexity, unknowns, and technical ambiguity.
- Enthusiasm for rapid prototyping, iterative development, and building the future of financial technology.
Benefits
