Senior Backend Engineer

Role overview

Build and scale backend infrastructure for financial products that connect users with decentralized protocols—supporting both onchain and offchain workflows. You’ll own backend APIs and services that power secure access to tokenized real-world assets (RWAs) and DeFi strategies, collaborating with product, smart contract, and frontend teams.

Responsibilities

• Design and implement scalable, secure backend systems and APIs for interacting with onchain protocols and offchain infrastructure.
• Define interfaces and workflows between backend services and blockchain networks (EVM and non-EVM) with smart contract engineers.
• Own integrations with custodians, identity/KYC providers, payments infrastructure, and third-party blockchain tooling.
• Support internal ops, investor services, and compliance teams with automation, auditability, and observability tooling.
• Establish and enforce backend engineering standards, best practices, and security protocols.
• Participate in code reviews and architecture discussions to improve engineering excellence.

Requirements

• 4+ years of backend software engineering experience.
• Strong familiarity with TypeScript, Go (Golang), or Python.
• Strong understanding of distributed systems, system design, and API development.
• Experience integrating with cloud infrastructure (AWS preferred), third-party services, and security/compliance-sensitive systems.
• Demonstrated interest in Web3 or DeFi (professional experience or side projects).
• Comfort in a fast-moving startup environment with high ambiguity and high ownership.
• Located in a US time zone (PT–ET).

Nice to haves

• Experience with Web3 data providers such as The Graph, Alchemy, or Moralis.
• Prior work on tokenized asset platforms, DeFi protocols, or custodial/wallet infrastructure.
• Understanding of Solidity or other smart contract languages.

What’s offered

• Competitive compensation including salary plus future token rights and/or equity (per preferences).
• Full benefits (medical, vision, dental) and flexible PTO.
• Remote-first, small team with early impact on vision and engineering practices.
