Truelogic Tech Lead at Truelogic leads technical execution by writing full-stack TypeScript code and building advanced AI-driven backend systems. The role involves guiding feature development, deploying custom workflows, and establishing AI coding discipline.

Responsibilities

Guide the development of end-to-end features for a lean team, making pragmatic trade-offs between rapid shipping and long-term code health.
Remain heavily hands-on, writing clean, production-grade code across the entire full-stack TypeScript ecosystem.
Move past basic implementations to deploy custom agentic workflows, state machine logic, and custom RAG pipelines.
Build custom guardrails, traceability frameworks, and confidence/quality algorithms to mathematically measure, test, and prove LLM output reliability.
Turn high-level, ambiguous ideas into functional, working code rapidly, prioritizing immediate execution over lengthy architecture meetings.
Establish rigorous code review processes, testing discipline, and guidelines for the responsible and mature use of AI coding assistants within the team.

Qualification

Deep NodeAdvanced

Required

Expert-level TypeScript proficiency with deep comfort utilizing advanced patterns (e.g., Generics and Discriminated Unions) to maximize shipping speed.
Deep Node.js experience, with a strong preference for Mastra or a proven background in building custom state-machine-driven backend logic.
Strong capabilities in modern web development; our primary stack is SvelteKit, but React or Vue wizards with the engineering DNA to pick up new frameworks fast are highly welcome.
A track record of deploying practical LLM-powered features or agents, paired with a solid understanding of token costs, evaluations, and prompt safety.
Advanced, daily use of next-gen engineering assistants (e.g., Claude Code, Cursor) to automate boilerplate, combined with the strict engineering discipline to manually debug syntax walls in minutes.
The ability to jump across the entire web stack autonomously without being blocked by business-logic friction or basic syntax.
Outstanding English communication skills with comfort working in an async-first, highly autonomous environment.
