Immediate Start! Lead Backend Engineer

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 Lead 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 as Tech Lead (or similar leadership role) in a startup environment, driving projects from idea to production under high ambiguity and fast iteration cycles.
• A track record of mentoring and up-leveling engineers to achieve their full potential.
• 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.
