Key responsibilities

  • Architect, develop, and maintain real-time APIs and backend systems for crypto trading, DeFi analytics, and digital asset tracking.

  • Manage streaming pipelines with Kafka to process high-throughput event data from blockchains and financial markets.

Job description

Octagon Talent Solutions is a full-service technology recruitment and staffing company based in South Florida. We humanize technical recruitment by identifying candidates' long-term career goals and assessing cultural fit when presenting opportunities. Our focus on long-term relationships helps ensure placements that last.


Our client is a well-funded Web3 fintech startup redefining the future of real-time financial infrastructure. Our platform bridges traditional finance and decentralized systems, enabling seamless, secure, and transparent access to blockchain-powered financial services.

They’re not just building APIs — they’re creating the data rails for the decentralized economy, supporting everything from real-time transaction monitoring to decentralized asset management. With deep backing from top VCs and a founding team of fintech and blockchain veterans, we’re scaling fast — and we’re looking for core engineers to shape what comes next.


???? What You’ll Do

  • Architect, develop, and maintain real-time APIs and backend systems powering crypto trading, DeFi analytics, and digital asset tracking.
  • Build scalable microservices with NestJS and gRPC, and design APIs used by developers, trading platforms, and financial institutions.
  • Manage streaming pipelines with Kafka to process high-throughput event data from blockchains and financial markets.
  • Implement WebSocket-based services using Bun to push live updates (price feeds, wallet events, smart contract logs).
  • Store and optimize time-series data using QuestDB for hot access and ClickHouse for long-term analytics and compliance reporting.
  • Secure and orchestrate APIs through APISIX, with features like rate limiting, authentication, and request transformation.
  • Contribute to infrastructure scalability, observability, and resilience in a mission-critical, high-uptime environment.
  • Collaborate with smart contract developers, frontend engineers, and data scientists to ship features end-to-end.


???? The Tech Stack

You’ll be working with bleeding-edge tools purpose-built for real-time finance:

  • NestJS – Modular TypeScript backend framework
  • gRPC + Protobuf – Blazing fast internal service communication
  • Kafka – Event streaming for blockchain and financial data ingestion
  • Bun – Ultra-fast runtime for high-frequency WebSocket communication
  • QuestDB – Low-latency time-series database for recent data
  • ClickHouse – Scalable analytics database for long-term storage
  • APISIX – Cloud-native API Gateway


???? What We’re Looking For

  • 5+ years in backend engineering, ideally with a focus on financial systems or high-throughput platforms
  • Strong proficiency in TypeScript, Node.js, and frameworks like NestJS
  • Experience with event-driven architecture and tools like Kafka
  • Comfort working with gRPC, Protocol Buffers, and microservices
  • Knowledge of blockchain fundamentals, smart contracts, or Web3 APIs (e.g., Ethers.js, Web3.js) is a big plus
  • Solid experience with WebSockets and real-time messaging systems
  • Proven ability to design and optimize time-series data solutions
  • Familiarity with cloud-native infrastructure (Docker, Kubernetes, CI/CD pipelines)
  • Security-first mindset — especially around financial and cryptographic systems
  • Self-starter attitude, with the ability to thrive in a fast-moving startup environment


???? What They Offer

  • Top-of-market salary + possible equity + crypto bonuses
  • Remote-first, async-friendly culture with flexible hours
  • The chance to work on the cutting edge of finance and Web3
  • A technical leadership role with influence over architecture and roadmap
  • Collaborative, transparent team culture with real ownership


???? Join the Future of Finance

If you’re passionate about building real-time, decentralized financial infrastructure with an elite engineering team, we’d love to meet you.
