Full-Stack Blockchain Engineer

Who We Are

We are building a new financial layer that reimagines how money moves across the internet. By merging the stability of traditional finance with the programmability of blockchain, we’re creating a powerful stablecoin ecosystem that unlocks access, yield, and utility for users and builders everywhere. Focused on transparency, scale, and real-world adoption, we’re redefining what digital money can do.

The Role

As a Full-Stack Blockchain Engineer, you will play a key role in designing and building the infrastructure and user-facing systems that power a next-generation stablecoin and programmable money platform. You will work across smart contracts, backend systems, and frontend integrations to create products that combine stability, transparency, and yield in a seamless user experience.

This role offers the opportunity to work at the forefront of decentralized finance, bridging traditional financial infrastructure with on-chain innovation. You will build systems that support real-world use cases such as global payments, programmable yield, and institutional-grade capital management, while ensuring security, scalability, and compliance.

You will collaborate with a high-performance team of engineers, product thinkers, and designers to create a product that expands access to secure, yield-bearing digital dollars for users around the world. Backed by a well-funded organization, you’ll have the autonomy to innovate and the resources to execute at scale, shaping the foundation of a new financial operating system.

Key Responsibilities

• Design and implement smart contracts for the issuance, redemption, and treasury operations of a fiat-backed or synthetic stablecoin.

• Design and maintain developer-facing APIs and SDKs to enable external integrations and programmatic access to core stablecoin functions

• Build backend systems for minting, burning, reconciliation, on/off-ramp flows, and transaction monitoring, ensuring accuracy, compliance, and real-time transparency.

• Design and implement new DeFi yield protocols backed by on and off-chain investment strategies.

• Create internal tools for treasury management, collateral tracking, and yield allocation.

• Define and evolve overall system architecture with an emphasis on security, transparency, scalability, and operational reliability.

• Collaborate with auditors, liquidity partners, and compliance teams on controls, attestations, and automation of KYC, AML, and regulatory reporting workflows.

• Drive engineering excellence through code reviews, testing, and adherence to security best practices across smart contract and backend systems.

• Provide technical mentorship and help shape a strong, collaborative engineering culture.

Knowledge & Experience

• Senior or Staff-level backend and blockchain engineer (7+ years) with deep, hands-on expertise in Solidity and TypeScript, capable of architecting and shipping production systems end to end.

• Deep EVM blockchain expertise, including smart contract design, deployment, and integration (ERC-20/4626, ERC-4337, vaults, oracles, bridges).

• Strong understanding of stablecoin mechanics, including issuance and redemption flows, collateralization models, and treasury yield strategies.

• Experience integrating with custody or vault systems such as Fireblocks, Copper or BitGo.

• Solid grasp of treasury operations, reconciliation, and proof-of-reserves frameworks.

• Practical experience with DeFi primitives such as lending protocols, AMMs and liquidity pools, and yield aggregators, with a clear grasp of how capital flows and incentives work under the hood.

• Proven experience developing microservice-based, event-driven distributed systems that handle financial data securely and reliably.

• Strong understanding of REST, and GraphQL (queries, mutations, subscriptions).

• Experience architecting and implementing responsive, immersive front ends using Vanilla React or Next.js.

• Experience designing or integrating compliance-aware DeFi systems (KYC, AML, KYT, travel rule).

• Deep understanding of security best practices across smart contracts, backend services, and inter-service communication.

• Proficiency with Docker, Kubernetes, and modern CI/CD pipelines for deploying and maintaining microservices in production.

• Competence with Git and collaborative development workflows in production environments.

Ideal Candidate Profile

• A creative problem-solver who is eager to innovate and push boundaries in the DeFi space.

• Possesses a deep understanding of web technologies and a strong grasp of blockchain fundamentals, particularly within DeFi.

• Thrives in scrappy start-up environments, seeing ambiguity as an opportunity rather than an obstacle.

• Takes full ownership of complex problems and transforms them into user-friendly solutions.

• Excels in collaboration, building trust and rapport with both technical and non-technical stakeholders.

• Adept at communicating complex concepts clearly and concisely.

• Relentless in delivering high-quality products, even under pressure.

• Understands that speed and agility are key competitive advantages and drives urgency and efficiency without compromising quality.

• Passionate about DeFi, with a commitment to continuous learning and staying at the forefront of this dynamic field.

Nice to Haves

• Knowledge of cross-chain infrastructure (LayerZero, Wormhole, Axelar, Hyperlane) and bridge security models.

• Experience integrating with Privy and Fireblocks APIs, or similar custody and wallet management systems.

• Familiarity with real-world asset (RWA) tokenization or on-chain yield instruments.

• Interest in governance, tokenomics, or monetary policy design for digital assets.

• Background in market structure, treasury operations, or automated market-making systems.

• Experience working with fiat onramp/offramp and reconciliation processes.
