backend Engineer

Building the Future of On-Chain Trading

Nado is building high-performance perpetual and spot trading infrastructure that combines the security of on-chain settlement with the speed of off-chain matching. Our team is focused on creating institutional-grade trading infrastructure that pushes the boundaries of what’s possible in DeFi.

What makes us different?

Nado operates at the intersection of traditional finance and blockchain technology. We’re building a vertically integrated trading platform that includes smart contracts, matching engines, market making infrastructure, and developer tools. As a Nado engineer, you’ll work on systems that process thousands of transactions per second while maintaining the security and transparency guarantees of blockchain technology.

We value engineering excellence, deep technical expertise, and pragmatic problem-solving. Our team includes experts in distributed systems, financial infrastructure, blockchain technology, and high-performance computing.

The Team

You’ll be joining a lean, highly technical team building production systems that handle real financial transactions. We write Rust microservices, Solidity smart contracts, and TypeScript tooling. Our engineers own features end-to-end, from smart contract deployment to backend services to developer SDK maintenance.

Our tech stack includes:

• Rust for high-performance backend services (matching engine, sequencer, gateway, signing services)
• Solidity for EVM smart contracts with custom optimization patterns
• PostgreSQL and Redis for data persistence and caching
• AWS infrastructure (ECS, VPC, Load Balancers, CloudFormation, Route53 and more)
• Custom EVM implementation for simulation and gas estimation
• Python for infrastructure automation and deployment tooling

About the Role

As a Backend Engineer at Nado, you will:

• Design and implement core trading infrastructure components including matching engines, order routing, risk management systems, and settlement logic
• Build and maintain microservices in Rust that handle high-throughput trading operations with strict latency requirements and reliability guarantees
• Develop and optimize smart contracts in Solidity for perpetual and spot trading, including clearinghouse logic, order verification, and settlement mechanisms
• Work on blockchain integration layers including transaction sequencing, EVM simulation, signature verification, and chain indexing
• Design database schemas and optimize query performance for PostgreSQL databases handling millions of trading events and real-time position updates
• Build developer tools, SDKs, and APIs that external teams use to integrate with Nado’s trading infrastructure
• Implement monitoring, alerting, and operational tooling to ensure maximum reliability and availability for production trading systems
• Collaborate on system architecture decisions affecting performance, scalability, security, and maintainability
• Participate in code reviews, write technical documentation, and contribute to engineering best practices
• Debug complex issues spanning multiple services, blockchain interactions, and third-party integrations

Requirements

• 4+ years of professional software engineering experience building production backend systems
• Strong proficiency in Rust or demonstrable ability to quickly master systems programming languages. Experience with async Rust (Tokio), web frameworks (Axum/Actix), and systems programming
• Solid understanding of distributed systems, database design, API design, and service-oriented architectures
• Experience with relational databases (PostgreSQL preferred) including schema design, query optimization, and transaction management
• Strong computer science fundamentals: data structures, algorithms, concurrency, networking
• Ability to read and reason about system performance, identify bottlenecks, and implement optimizations
• Self-directed work style with ability to own projects from conception through deployment
• Strong written and verbal communication skills for technical documentation and cross-team collaboration

Preferred

• Experience with blockchain technology, smart contracts, or cryptocurrency trading systems
• Solidity smart contract development experience, especially with complex DeFi protocols or exchanges
• Understanding of EVM internals, gas optimization, and blockchain indexing patterns
• Experience building financial systems, trading infrastructure, or high-frequency trading systems
• Familiarity with order matching algorithms, market microstructure, or trading venue operations
• DevOps experience with Docker, AWS (ECS, RDS, ElastiCache), Infrastructure as Code (CloudFormation, CDK, Terraform)
• Contributions to open-source Rust or blockchain projects
• Experience with WebSocket APIs, real-time data streaming, and pub/sub architectures
• Knowledge of EIP-712 signatures, account abstraction, or layer 2 scaling solutions

Our Engineering Culture

• Code quality matters: We use clippy, rustfmt, ESLint, Prettier, and enforce lint-clean code through CI.
• Test everything: Integration tests, unit tests, property tests. We run comprehensive test suites before every deployment.
• Ownership and autonomy: Engineers own features from design through deployment and maintenance.
• Pragmatic problem-solving: We value simple, maintainable solutions over clever complexity.
• Continuous improvement: Regular code reviews, architecture discussions, and knowledge sharing.
• Production-first mindset: Our code handles real money, so we prioritize reliability, security, and observability.

Equal Opportunity

We hire based on technical merit, problem-solving ability, and cultural fit. We welcome applications from candidates regardless of their background, location (within reasonable timezone overlap), or prior experience with blockchain technology.

We consider qualified applicants with diverse backgrounds and encourage applications from candidates who may not meet every listed requirement but have strong fundamentals and eagerness to learn.

Note: This role requires the ability to work with financial systems and blockchain technology. Candidates should be comfortable working in a fast-paced environment where code quality and system reliability directly impact users’ financial outcomes.
