Senpi is the first AI Wallet

  • a new category of intelligent wallets that

think, trade, and protect  alongside users. In just four months since launching on Base, Senpi has processed 285K+ AI auto-trades , achieved a 45% win rate (~3× higher than typical exchanges), and welcomed 200+ traders to the "1000% Club."

Backed with $4M in Seed capital by top investors including Lemniscap, Coinbase Ventures, and SuperLayer, we're building on a track record of OG Ethereum innovation — from creating one of the first smart wallets approved by Apple to pioneering AI blockchain search.

With millions in trading volume and 75%+ retention already, we're now rolling out iOS and Android apps, expanding multi-chain, and pushing deeper into perps, futures, and yield strategies. At Senpi, you won't just be joining another startup — you'll be helping reinvent the wallet itself into the intelligent agent of onchain finance.

We're looking for a Staff Backend Engineer to design and scale the systems powering Senpi's AI-driven trading automations, copy-trading groups, referral rewards, and intelligent onchain infrastructure.

What You'll Bring

  • 7+ years of hands-on experience building and scaling production-level backend systems.
  • Proven experience in a startup environment , driving projects from idea to production under high ambiguity and fast iteration cycles.
  • Mastery of distributed systems, cloud architecture, and high-performance services
  • Ability to independently own end-to-end projects — from requirements gathering to design, implementation, testing, and deployment.
  • Deep experience with blockchain development
  • onchain APIs, transaction processing, and scaling decentralized systems.

  • Familiarity with crypto wallets, trading systems, and DeFi protocols is a strong plus.
  • Proven work with AI / ML pipelines , including retrieval-augmented generation (RAGs), embeddings, and prompt engineering for LLM-powered services.
  • Ability to integrate AI inference and intelligence layers into production-grade products.
  • A true 0?1 builder's mindset , capable of creating systems and processes from scratch in a high-ambiguity environment.
  • Deep knowledge of modern development practices (CI / CD, observability, containerization, etc.) and a passion for applying them to the fast-evolving crypto landscape.
  • Experience in monitoring, troubleshooting, and resolving critical incidents. Comfortable with taking on-call responsibilities, leading incident response, implementing root cause analysis, and driving long-term stability improvements.
  • Curiosity and passion for AI, crypto, and trading, with an eagerness to shape the future of autonomous onchain agents and AI-powered wallets.
  • Benefits & Perks

    Culture of rapid iteration and building in public

    Highly competitive compensation, stock options program, and token upside

    Flexible work schedule.

    Company laptop and home office equipment allowance.

    Health, dental, vision insurances.
