A mid- to senior-level Backend Engineer is required to join an ambitious team focused on scaling a state-of-the-art infrastructure layer. This infrastructure is designed to allow engineering teams to self-serve 90% of their needs, enabling this role to focus entirely on high-level, high-impact projects. The successful candidate will collaborate closely with quants, infrastructure specialists, and data engineers to build a centralized pricing plane and an extremely dynamic pricing system that determines market competitiveness in real time.

Key Responsibilities

• Develop the Entity Service API: Build and maintain a core central configuration plane used to manage assets, mappings, market hours, data providers, smart contract parameters, algorithm parameters, and more.
• Build the Entity Service UI: Deliver an internal UI allowing team members to propose changes, review configurations, and leave comments, backed by robust Access Control Lists (ACL) and user management.
• Architect a Low-Latency Pricing System: Assist in designing and implementing a highly reliable, dynamic pricing engine capable of pricing every incoming transaction in real time to optimize liquidity attraction.
• Collaborate Across Teams: Partner with quants, infra, data, and backend engineers to establish a centralized pricing plane reflecting precise real-dollar values across every part of the system.
• Propose and Own Initiatives: Take stock of system needs, evaluate what delivers the most value, and propose independent workflows and paths forward.

Technical Experience

• Golang Expertise: Strong experience as a Go engineer with a deep understanding of how to leverage AI tools effectively in the development process while maintaining rigorous validation criteria.
• Data & Schema Design: Deep expertise with database schema design, evolution, and iteration.

• Modern Tech Stack: Hands-on experience with Postgres, NATS, Redpanda, gRPC, REST APIs, and WebSockets.

Professional Attributes & Characteristics

• Security-Minded: A proactive approach to identifying and decreasing security attack vectors across the backend ecosystem.
• AI Power User: An engineer who utilizes AI effectively to accelerate workflows, validates all outputs critically, and implements strict technical guardrails rather than relying on unverified generation.
• Solution-Oriented: Focused on enabling internal teams and engineers to move as fast as possible by addressing requests and unblocking technical dependencies.
• Humble & Adaptive: A strong willingness to learn from quants, operations, and cross-functional engineering teams, maintaining flexibility without being attached to rigid legacy methods.
• Mission-Driven & Collaborative: A team-first competitor focused on overall organizational success, execution, and collective goals.
• Disagree and Commit: Open to voicing proposals and participating in rigorous debate, with a proven ability to fully commit to and execute decisions 100% once a path is finalized.
