Technical Lead, Applications

ABOUT THE ROLE

A1 is building a proactive AI system that carries work forward across conversations, tools, and time.

As Technical Lead, Applications, you directly own the core application architecture that connects AI systems to real-world user experiences. You are responsible for the design, reliability, and evolution of backend services, APIs, and client integrations across mobile and desktop.

This is a hands-on leadership role. You stay close to the code, make critical architectural decisions, and ensure the system remains fast, reliable, and coherent as it scales.

FOCUS

- Own the application engineering strategy and execution across backend, mobile, and desktop.

- Lead and grow a small, senior applications team, including backend, mobile, and desktop engineers.

- Ensure production-grade reliability: observability, monitoring, retries, fallbacks, and failure handling.

- Set the architectural direction for AI-powered product workflows, APIs, and client integrations.

- Ensure AI capabilities are integrated into the product with clear abstractions, predictable behavior, and graceful failure modes.

- Partner closely with Machine Learning leadership to translate model capability into shippable product features.

- Make high-impact decisions across latency, cost, reliability, security, and user experience.

- Establish a strong execution culture through code reviews, design reviews, and hands-on technical leadership.

- Ensure production readiness: observability, monitoring, retries, fallbacks, privacy, and cost controls.

- Balance speed and discipline – shipping quickly without compromising long-term system quality.

IDEAL EXPERIENCES

- Significant experience leading application or product engineering for complex systems.

- Strong hands-on background building and shipping backend systems used in production.

- Experience delivering AI-powered products, with a deep understanding of model integration trade-offs.

- Excellent system des...
