About the Role

We are seeking an exceptional Senior Staff Backend Engineer / Backend Engineering Lead to join our high-impact engineering team. This role is for a deeply technical leader who can drive architectural decisions, mentor top-tier talent, and build scalable, high-performance backend systems that serve as the backbone of our core products.

You’ll own mission-critical infrastructure, distributed systems, and services that support massive scale and reliability. As a senior technical authority, your decisions and code will have a direct and lasting impact on the company's technology and millions of users worldwide.

What You’ll Do

● Architect, design, and lead the development of robust, scalable backend services and infrastructure.

● Drive technical direction and decision-making across projects, ensuring high availability, performance, and maintainability.

● Own end-to-end systems: from planning and design through deployment and operations.

● Lead technical deep-dives, mentor engineers across teams, and elevate engineering standards through code reviews and architectural discussions.

● Optimize backend performance across data stores, cache layers, and messaging systems for ultra-low latency and high throughput.

● Champion observability, monitoring, and resilience in production environments.

● Partner closely with cross-functional leads—including product, frontend, and infrastructure—to align technical strategies with business goals.

What We’re Looking For

● 10+ years of backend development experience, with a track record of building and scaling mission-critical systems.

● Expertise in one or more backend languages (Go, C++, Java, Rust) and a deep command of modern software architecture.

● Profound understanding of distributed systems, microservices, concurrency, and network architecture.

● Experience designing high-performance, low-latency backend infrastructure capable of handling complex workflows at scale.

● Mastery of data systems—relational, NoSQL, caching, and message brokers (Kafka, RabbitMQ, etc.)—and how to apply them effectively.

● Strong foundation in cloud platforms (AWS, GCP, or Azure) and orchestration tools like Docker and Kubernetes.

● Demonstrated leadership in driving initiatives, mentoring engineers, and fostering a culture of technical excellence.

● Deep problem-solving ability, engineering intuition, and a passion for clean, impactful code.

Bonus Points

● Experience leading engineering efforts in high-growth startups or elite tech companies.

● Prior work on real-time systems, large-scale data infrastructure, or fintech platforms.

● Familiarity with algo trading, high-frequency trading, or fixed income platforms. ● Background in applied mathematics, quantitative modeling, or computer science research.

Why Join Us?

● Join a world-class engineering team tackling complex challenges at global scale.

● Competitive compensation, including equity and premium benefits. A culture of ownership, autonomy, and relentless technical curiosity.

● Work on a modern tech stack in an environment that moves fast and encourages bold thinking.

● Direct impact—your ideas and execution will shape our platform and business outcomes. If you’re a senior technical leader who thrives on solving hard problems and driving innovation at scale, we’d love to hear from you.
