Job description

ParetoX is an early-stage technology company building next-generation infrastructure for trading, financing, and settlement. Combining auction theory, mechanism design, and artificial intelligence, we aim to create more capital-efficient, secure, and scalable markets across asset classes—from digital assets and agentic economies to commercial finance and ERP systems.

Our founders are experienced entrepreneurs, operators, and academics with deep expertise in financial markets, market structure, and distributed systems.

This is an early, high-impact role for a systems engineer. In this role, you will build institutional-grade market infrastructure from the ground up, working directly with the founders and engineering leadership to design, implement, and operate performance-sensitive systems as ParetoX moves from initial build to production.

Initially, you will focus on the systems supporting our institutional trading venue, including order and execution workflows, market data, client connectivity, matching-platform integration, and production reliability and performance.

What You’ll Do

• Design and build high-performance systems for order handling, execution processing, and market-data workflows.
• Build integrations with the matching platform, institutional clients, custodians, and settlement providers.
• Develop event-driven services and pipelines for real-time, high-volume trading activity.
• Optimize latency, throughput, memory use, and fault tolerance across critical services.
• Build monitoring, observability, recovery, and operational tooling for production systems.
• Establish automated testing, CI/CD, deployment, and release practices.
• Diagnose production issues and improve system reliability and operational resilience.
• Translate market mechanics and product requirements into robust technical systems.
• Contribute across architecture, implementation, code review, and production operations.

What We’re Looking For

• 5+ years of professional software engineering experience, with a track record of owning performance-sensitive or mission-critical production systems.
• Proficiency in a systems-level language such as Rust, C++, or Java; Rust is a plus.
• Experience with distributed systems, concurrency, networking, and event-driven architectures.
• Familiarity with low-latency or high-throughput computing, memory management, and performance optimization.
• Comfort working with large-scale data pipelines and real-time data flows.
• Ability to write clear, well-tested code that can be maintained by a growing team.
• Hands-on experience operating production systems, including monitoring, deployment, and incident response.
• Strong attention to correctness, consistency, reliability, and technical detail.
• Understanding of financial market structure or the ability to learn market mechanics quickly.
