Our client is a high-performance technology development firm responsible for building and operating the infrastructure behind the world’s largest and most active digital asset launchpads. Processing approximately $1B in daily volume, the platform operates at the bleeding edge of crypto scale, requiring systems designed for ultra-low latency, high throughput, and constant high-concurrency load.

The organization is seeking a Lead Backend Engineer to own the most complex technical challenges across the system. This is a high-stakes, high-impact role within an intense, in-person environment. The team is composed of high-agency builders who value speed, immediate impact, and rigorous engineering judgment. This position is ideal for an engineer who thrives under pressure and is motivated by the opportunity to solve ambiguous, cross-cutting problems that others cannot.

Key Responsibilities

• System Ownership: Take full accountability for the most difficult backend challenges, addressing performance bottlenecks, scaling limits, and maintaining system correctness under extreme load.
• Architectural Leadership: Set the technical direction for core backend systems, making principled architectural decisions that balance rapid delivery with long-term maintainability.
• Distributed Systems Design: Design, build, and operate high-stakes distributed services relied upon by a massive global audience daily.
• Problem Resolution: Proactively identify systemic issues and drive them to resolution, navigating ambiguity and cross-functional complexities.
• Engineering Excellence: Raise the bar for the backend engineering organization through rigorous design and code reviews, mentoring peers, and modeling elite engineering judgment.

Requirements

• Scale & Experience: Proven track record of building and operating distributed systems at significant scale multiple times.
• Technical Stack: Deep proficiency in Rust, Go, or TypeScript.
• Data Expertise: Extensive knowledge of databases and data modeling, including a sophisticated understanding of tradeoffs regarding consistency, performance, and reliability.
• Agency & Ownership: A high-agency, ownership-driven mindset with the ability to take ambiguous problems to concrete outcomes without needing constant direction.
• Problem Solving: A reputation for solving complex technical hurdles that have stalled previous efforts.
• Domain Knowledge: Previous experience in the crypto or blockchain space is considered a significant plus, though not a strict requirement.
• Work Style: Comfort with an intense, fast-paced, and unconventional work schedule. Our client operates primarily in-person.

Benefits

• Unmatched Autonomy: Significant ownership over technical decisions and the freedom to drive impactful changes.
• Scale Exposure: Direct experience managing systems operating at the absolute edge of current crypto and financial technology scale.
• Immediate Impact: The ability to ship code rapidly and see real-world results and user interaction immediately.
• Compensation: Highly competitive package including Base Salary and Equity/Tokens ranging from $75K – $500K, commensurate with experience and impact.
