Lead AI Engineer (LLM & Agents)

As a Lead AI Engineer at Trust Wallet, you own the backend and Agent systems behind our LLM-powered products. You'll build Agent workflows, define how we measure quality, keep them reliable in production, and shape where the product goes next. This role is for someone who has shipped LLM features to real users, stayed with them after launch, and can prove with data that their changes made things better.

What you'll do

• Design, build, and maintain multi-turn conversation systems, including context management, tool calling, knowledge retrieval (RAG), state management, and human handoff.
• Define success criteria with Product, Design, and QA leads, and measure the impact and side effects of every change before and after release.
• Turn production failures into evaluation samples and regression tests.
• Isolate the root cause of failures: model judgment, knowledge gaps, abnormal tool responses, backend instability, or conflicting rules, and apply the right fix for each cause.
• Handle timeouts, retries, graceful degradation, async jobs, and third-party dependency failures to ensure production reliability.
• Make sure every issue is traceable through logs, every change is versioned, and every failure has a recovery path.
• Give clear, reasoned positions on requirements, covering feasibility, cost, risk, and alternatives.
• Share progress, blockers, ETAs, and next checkpoints proactively, and track real-world impact with clear documentation and handover materials after launch.

What you bring

• Production LLM or Agent experience at scale: you've built features used by 10,000+ active users and maintained and improved them after launch.
• Strong backend engineering fundamentals: you're comfortable owning production code, APIs, data flows, and incident troubleshooting.
• Real evaluation discipline: you've built evaluation sets, regression suites, and production monitoring, and you can explain how you confirmed an improvement was real rather than random fluctuation.
• An ownership mindset: you make decisions, surface risks early, and don't consider a feature done until it's verified in production.
• Web3 experience, preferably 1+ year in a crypto, DeFi, or Web3 company such as a wallet, exchange, L1/L2 protocol, or DeFi platform.

What we offer

• Fully remote, global role with flexible working hours.
• Competitive salary and benefits.
• Excellent learning and career development opportunities.
• Work alongside diverse, world-class talent in an environment where growth is endless.
