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 Golang Engineer to architect, scale, and secure the high-performance systems powering Obinex.

The role

We’re seeking a Senior Golang Engineer with 6–10+ years of experience building distributed systems, high-throughput architectures, or fintech/Web3 platforms. You’ll own critical backend components of our exchange infrastructure, from the matching engine and internal ledger to high-performance microservices and low-latency communication systems.

You’ll work closely with Engineering, Product, Security, and Compliance to deliver infrastructure that is fast, scalable, fault-tolerant, and regulator-grade. This role sits at the core of Obinex’s technical foundation.

You’ll:

• Design, build, and maintain Golang microservices powering core exchange functions (matching, orders, balances, staking, wallets).
• Architect scalable, low-latency systems for high-volume trading environments.
• Implement robust database schemas, caching strategies, and concurrency-safe processes.
• Build internal APIs, event-driven systems, and communication layers between services.
• Collaborate closely with Product and Security to translate financial mechanics into resilient backend logic.
• Benchmark performance, identify bottlenecks, and optimize systems for throughput and reliability.
• Integrate with blockchain, custody, KYC/AML, and risk engines.
• Ensure reliability through comprehensive testing, tracing, observability, and automation.
• Contribute to Obinex’s internal engineering standards, documentation, and long-term technical roadmap.

What you will bring?

• 6–10+ years of software engineering experience, with at least 3–5 years working primarily with Golang.
• Proven experience building high-load distributed systems, ideally in fintech, trading, or Web3.
• Mastery of Go’s concurrency model (goroutines, channels, sync primitives).
• Strong understanding of microservices, event-driven architectures, and pub/sub systems.
• Hands-on experience with PostgreSQL, Redis, message brokers, and caching layers.
• Background in designing resilient and observable systems (monitoring, tracing, logging).
• Strong security mindset — familiar with secure coding practices and sensitive data handling.
• Experience collaborating in cross-functional teams with Product, Design, and Security.
• Discipline in clean code, testing, and long-term maintainability.

Nice to have

• Experience building financial or trading systems (order books, internal ledgers, settlement flows).
• Knowledge of crypto exchanges, custody systems, wallets, or blockchain integrations.
• Exposure to Fireblocks, Chainalysis, or similar infra.
• Familiarity with Rust, Go plugins, GRPC, or high-performance networking.
• Experience with KYC/AML-integrated environments or regulated FinTech systems.

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 high-ownership engineering role where your work directly defines the core infrastructure of the first gamified CEX.
• Direct exposure to regulatory-grade engineering challenges in fintech + Web3.
• Real opportunity to grow into Backend Lead within 18–24 months.
• Global, remote-first culture, obsessed with execution, clarity, and innovation.
