Backend Engineer



New York, NY, USA
145,000 – 195,000 USD per year
Posted on Friday, May 3, 2024

Bullpen is building an onchain Robinhood. We combine AI-generated insights with one-click execution in a mobile-friendly interface. Bullpen's first product, a Telegram trading bot, is the first of its kind to embed both a non-custodial wallet (powered by passkeys) and a robust mini-app (akin to a pocket Bloomberg). Our mission is to give retail access to the tools and information pro crypto traders use.

About the role

We are looking for a talented and motivated backend engineer to join our team. You will work closely with the founding team to implement and deploy our product roadmap with an eye for scalability.

  • Partner closely with the founding team to build products with Typescript (primarily), JVM (Kotlin), and Rust
  • Complete medium to large features (each with many tasks) independently without guidance and identify and drive changes as needed for assigned codebase, product area, or systems
  • Leverage best-practices in building scalable backend systems that can handle tens-of-thousands of simultaneous users with minimal latency
  • Review code and technical proposals with feedback for other team members
  • Build consumer products that combine your expertise of distributed/p2p systems, data engineering, and blockchain/cryptocurrency

About you

  • Based in NYC (or willing to re-locate)
  • 3+ years of experience developing large complex software and contributing to system design or architecture
  • Have a level of expertise in distributed systems and one or more of networking, storage, databases, operating systems, and runtimes
  • Expertise with microservices architecture, cloud environments (AWS), containerization tools such as Docker, orchestration such as kubernetes, and data warehouse maintenance such as AWS Glue
  • Strong communication and collaboration abilities


  • Strong interest in crypto/web3 (particularly Solana)
  • Experience writing smart contracts in Solidity or Rust + Anchor
  • Experience participating in past smart contract code audits (maintainer or auditor)
  • Experience at fast-growing companies or startups

Why join us

  • Join one of the most talented teams in all of consumer crypto
  • Highly competitive compensation package & optimized tax structure compared to the vast majority of web3 startups
  • Top 1% of benefits across the web3 startup space
  • 100% of premiums covered on highest quality medical/dental/vision
  • Aggressive company 401(k) match
