Senior Backend Engineer- Remote, Worldwide

Are you the one?

We are looking for an experienced Senior Backend Engineer to design and build high-performance systems that power institutional-grade blockchain and DeFi applications.

You are a builder at heart who thrives on solving complex distributed systems challenges and transforming ideas into scalable, reliable infrastructure. You have a deep understanding of software engineering principles and fluency in one or more modern programming languages (e.g. Go, Python, Rust, C#, or Java).

You care deeply about writing clean, maintainable code, designing for performance and enterprise-level security, and building systems that scale gracefully under real-world conditions.

This is a remote-first role, working with a globally distributed team of engineers and researchers, and in close collaboration with leading financial institutions and blockchain ecosystem partners.

Responsibilities:

• Design, develop, and maintain institutional-grade financial services backend systems and APIs that are efficient, secure, and scalable.

• Architect distributed systems that integrate blockchain data, financial logic, and external services with strong guarantees of reliability and correctness.

• Build high-throughput data pipelines and services that interact with on-chain infrastructure and blockchain protocols like DeFi.

• Continuously optimize systems for speed, scalability, and resilience, using data-driven insights and monitoring tools.

• Collaborate with cross-functional teams, blockchain engineers, researchers, and product leads, to deliver institutional-grade solutions.
  

Skills:

• 7+ years of software engineering experience, with a solid grasp of design patterns, testing strategies, and best practices.

• Strong programming skills in at least one of: Go, Python, Rust, C#, Java, or TypeScript/Node.js.

• Deep experience with databases, both relational (PostgreSQL, MySQL) and non-relational (MongoDB, Redis), including schema design and performance tuning.

• Proven ability to design, scale, and maintain distributed systems from initial architecture through production operations.

• Solid understanding of API design, system observability, and performance optimization at scale.

• Working knowledge of containerization, CI/CD pipelines, and cloud environments (AWS, GCP, or Azure).

• Background in large-scale financial or blockchain systems and organizations (Hedge Funds, FinTech, Asset Management, or Payments), with exposure to compliance, security, and data-sensitivity requirements.

• Understanding of financial markets and products, including market structure, trading workflows, and risk considerations
  

Nice to have:

• Familiarity with on-chain/off-chain integrations, blockchain data indexing, or DeFi protocols.

• Experience with data pipelines, AI/ML-driven systems, or event-driven architectures.

• Contributions to open-source projects, cloud-native systems, or technical leadership in cross-functional engineering teams.

• Understanding of cryptographic concepts or zero-knowledge technologies is a plus.
