About Obinex

Obinex is the first fully gamified centralized exchange (CEX), where finance meets game mechanics and NFT-powered experiences. We’re building the platform that will redefine how millions of users interact with trading, staking, and digital economies.

Our MVP is in development, and we’re assembling a global founding team. Now we’re looking for a Senior Rust Engineer to architect, scale, and secure the high-performance systems powering Obinex.

The role

We’re seeking a Senior Rust Engineer who can design scalable architectures, make forward-looking technology choices, and bring clarity to the rationale behind those choices. You’ll collaborate closely with the Head of Engineering, DevSecOps, and Product teams to:

• Design and implement the Matching Engine (order book) in Rust, with a focus on performance, concurrency, and fault tolerance.
• Build and optimize backend services in Rust and Golang for trading, staking, and NFT modules.
• Architect scalable APIs and microservices to handle thousands of transactions per second.
• Optimize concurrency, parallelism, and memory safety in mission-critical financial systems.
• Collaborate with DevSecOps to embed security, KYC/AML, and compliance hooks.
• Continuously evaluate technology choices and how to rebuild systems with today’s best practices.
• Mentor backend engineers and set the technical culture for Obinex.

What you will bring?

• 10+ years of professional experience as a Backend Engineer.
• 4+ years of Rust experience, with proven projects in production.
• Proven experience developing a HFT system is a plus.
• 5+ years of Golang experience (production systems).
• Strong background in high-performance distributed systems (low latency, event-driven).
• Proven expertise with databases (PostgreSQL, NoSQL, time-series DBs) and messaging systems (Kafka, NATS, RabbitMQ).
• Strong understanding of system concurrency, parallelism, lock-free structures, async Rust, and goroutines.
• Ability to clearly explain architectural decisions, trade-offs, and long-term projections.
• Track record of building and scaling production trading or fintech-grade systems.

Nice to Have

• Experience with trading platforms, exchanges, or high-frequency systems.
• Familiarity with cloud-native architectures (AWS/GCP, Kubernetes, Terraform).
• Expose to time-series databases (InfluxDB, Timescale).
• Knowledge of cryptography, secret management, and compliance frameworks (SOC 2, PCI DSS, ISO 27001).

What will you get?

• Equity from day one in a global fintech startup.
• Base salary starting once our $5M fundraising round closes (currently in progress).
• A role with massive ownership: you’ll design the infrastructure and security backbone of Obinex.
• Direct exposure to regulatory-grade challenges in fintech + Web3.
• Real opportunity to grow into Head of Blockchain within 18–24 months.
• Global, remote-first culture, obsessed with execution and innovation.
