OUR CLIENT

Our client is an elite, tech-powered real estate media company and brokerage that is completely reinventing how real estate is bought, sold, and experienced. Founded by an industry pioneer, they have built a vertically integrated ecosystem combining luxury residential sales, a powerful global education platform, and an in-house creative agency. They treat technology as a core differentiator, empowering lean, autonomous engineering teams to ship quickly, write clean code, and build the future of real estate tech.

JOB SUMMARY

The Hands-On Tech Lead is an elite full-stack "Unicorn" Generalist who leads technical execution from the front by writing code every single day. In this role, you will sidestep endless theoretical debates and take complete ownership of end-to-end features, building high-performance TypeScript APIs, custom state-machine-driven backend systems, and the user-facing web experiences that connect them. This position requires an expert-level engineer with a strong bias to action who uses next-gen AI coding tools with extreme discipline as a mature utility, focusing heavily on AI engineering maturity to mathematically measure and prove the output reliability of custom agentic systems.

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.

QUALIFICATIONS AND JOB REQUIREMENTS

• 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 ba
