Member of Technical Staff (MTS) –Senior Core Full-Stack / Backend

Job description

**About Us** Tetriz is an AI Engineering Intelligence platform that helps engineering organizations become AI-native, faster. We measure how AI coding tools like Cursor, Claude Code, and GitHub Copilot are actually used, improve engineer effectiveness through prompt and workflow coaching, and help engineering leaders demonstrate AI ROI with board-ready, defensible insights. **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-concurrency latency spikes. **Our Expected Stack:** **Go (Golang)** or high-performance backend equivalents, relational/non-relational databases, Redis cache/queuing systems, and modern, highly optimized web engineering frameworks. **Who You Are** **Experience:** **6-8** **years** of intensive full-stack or backend engineering experience. **Startup DNA:** Proven track record in high-velocity tech startups with heavy execution demands. You excel in ambiguous environments where the destination is clear but the map is yet to be drawn. **Strong Fundamentals:** You know how to build software that scales. You understand memory management, concurrency primitives, asynchronous task processing, and how web protocols *actually* break under load.
