small senior teams, extreme ownership, hands-on builders, and AI-native products.

We operate with a builder culture where engineers have end-to-end responsibility for launching and scaling AI-powered products across the studio.

Role Overview

We are looking for an exceptionally strong Tech Lead (AI + Full Stack) who codes every day and leads through architecture, execution, and example. This role is designed for elite senior builders who thrive in zero-to-one environments, enjoy solving complex problems, and can ship production-grade systems quickly.

You will:

Architect core systems Build them with your own hands Integrate AI tooling & agents Mentor engineers through technical leadership Drive engineering excellence across multiple ventures

This is not a people-management role -- it is a high-impact IC leadership role.



What You'll Do

Build & Lead With Technical Depth (70-90% hands-on)

Architect, build, and ship backend and full-stack systems end to end. Lead engineers through code reviews, architecture reviews, and solid technical decision-making. Own engineering execution across multiple ventures.

Design Scalable, AI-Native Architectures

Build modular APIs, distributed systems, and cloud-native microservices (Azure). Integrate AI models, retrieval workflows, and multi-agent systems into production applications. Work with Python, OpenAI, LangChain, LlamaIndex, vector databases, and agent toolchains.

Engineer With Excellence

Write high-performance, production-grade code (C#/.NET as primary). Use Python for AI workflows, automation, and data integrations. Build systems optimized for reliability, performance, and observability.

Full-Stack Ownership

Collaborate with frontend engineers to deliver seamless end-to-end experiences. Design clean APIs, interfaces, and developer workflows.

DevOps + Cloud Execution

Manage CI/CD pipelines, IaC, and Kubernetes deployments on Azure. Ensure systems are scalable, fault-tolerant, secure, and well-instrumented.

Technical Leadership & Mentorship

Mentor engineers and uplift technical standards across the stack. Provide architectural direction and guide complex technical initiatives. Contribute to hiring and shaping engineering culture.
