About the job
The company is pioneering the future of asset tokenization by offering exposure to institutional-grade securities and structured products onchain – accessible, global, and compliant. Co-founded by former investment professional Dennis Dinkelmeyer and seasoned serial entrepreneur Fabrice Grinda, aims to bridge the gap between traditional and decentralized finance. Since launching in October 2024, has grown to over $1b in total value locked (TVL) across its range of investment products, reflecting strong market fit and demand. The company raised a $9m seed round from top-tier investors including BlockTower, Framework Ventures, and Coinbase Ventures and others – now is looking for outstanding talents to scale and execute on its vision of a more open and efficient financial system.
Your Key ResponsibilitiesEarly Engineering Ownership
Operate as a core contributor in a lean, high-signal team, shaping system design, security posture, and engineering standards from first principles.
Distributed System & Backend Architecture
Design and maintain high-throughput, fault-tolerant backend systems handling onchain/offchain data flows (indexers, event processors, transaction pipelines).
Strong focus on idempotency, consistency, and observability.
API & Service Layer Design
Build and evolve typed, versioned APIs (REST/GraphQL) with clear contracts, enabling reliable integrations across internal services and external partners.
Emphasis on performance, caching strategies, and rate limiting.
Fullstack Development (TypeScript-first)
Develop end-to-end features using NestJS (backend) and React (frontend) within a monorepo architecture (Nx/Yarn workspaces).
Maintain strong typing, modularity, and DX standards.
Blockchain & Web3 Integration
Integrate with EVM networks using libraries such as viem / wagmi / ethers, handling:
Smart contract interactions (reads/writes) Transaction lifecycle management (simulation, signing, submission, monitoring) Wallet connectivity (EOA + smart wallets / MPC / Safe)
Security & Reliability
Apply security best practices across the stack:
Auth (OAuth, JWT, API keys) Infra security (WAF, rate limiting, isolation) Smart contract interaction safety (simulation, validation)
Contribute to a security-first culture with strong review processes.
CI/CD & Developer Experience
Maintain fast iteration cycles with automated testing, GitHub Actions, and continuous deployment. Optimize for high deployment frequency with minimal risk.
Experience
6+ years of experience building production-grade systems, with strong expertise in:
TypeScript / Node.js (NestJS preferred) React (or similar modern frontend frameworks) PostgreSQL (query optimization, indexing, migrations)
Web3 / DeFi Expertise
Strong understanding of:
EVM architecture and transaction lifecycle DeFi primitives (AMMs, vaults, yield strategies) Smart contract interaction patterns
Bonus: experience with Solidity, Foundry/Hardhat, or auditing
Systems Thinking
Ability to design systems that handle:
High data throughput (onchain events, logs) Distributed components Failure scenarios (RPC issues, reorgs, partial failures)
Security Mindset
Deep understanding of application and infrastructure security, including:
Secure API design Secrets management Attack surface reduction in Web3 contexts
Ownership & Autonomy
Comfortable operating in a low-process, high-ownership environment, making pragmatic trade-offs and driving projects end-to-end.
Communication & Collaboration
Strong ability to work asynchronously in a remote-first, globally distributed team, with clear written and verbal communication.
Timezone
Ability to overlap with EST / GMT working hours.
