About Us We are an AI-first engineering intelligence platform building the future of developer workflows completely from scratch. We are the core engineering team behind Fi , where we built and scaled fintech systems for over 3 million users. We don’t stitch together basic API wrappers; we work directly on deep system architectures. If you want a highly challenging, completely flat environment where you own your vertical without bureaucratic red tape, this is it. The Role & Technical Depth We are shifting past static components into high-concurrency, data-heavy production web flows and fully autonomous AI agent systems. We need a stellar engineer who can write high-performance backends and wrap deterministic, bulletproof software around non-deterministic AI outputs. Build the Stack: Design, develop, and optimize core services, heavy web architectures, and transaction flows for our platform. Production-Grade AI Agents: Take AI loops out of the "toy project" phase and build the software loops, validation guardrails, and caching mechanisms required to run them reliably at scale. Performance Engineering: Diagnose and resolve complex backend bottlenecks, database deadlocks, and high
