A1 is building a proactive AI system that carries work forward across conversations, tools, and time.
We are looking for a Head of Engineering who can drive engineering execution, structure engineering workstreams, and help build a high-performing engineering team.
This role focuses on turning product and technical direction into reliable delivery, and ensures the team ships effectively and consistently. A strong technical foundation in system architecture is a must.
The role involves helping manage engineering workstreams, supporting technical decisions, and leading engineering hiring across the globe.
Engineering Execution
Help structure engineering workstreams and ensure projects move forward efficiently
Identify risks, unblock engineers, and maintain steady development velocity
Ensure high engineering standards while keeping teams focused on shipping
Translate product direction and technical strategy into clear engineering execution
Technical Guidance
Contribute to key architecture discussions and technical decisions
Support engineers in evaluating system design choices and implementation trade-offs
Ensure systems are implemented in a scalable and maintainable way
Team Building and Recruiting
Build and scale a strong engineering team across China, US and Europe.
Recruit high-quality engineers and help maintain a strong hiring bar
Establish structured hiring processes and interview standards
Cross-Team Coordination
Work closely with product, research, and leadership teams
Ensure alignment across different engineering efforts and locations
Help resolve technical and organisational bottlenecks
Strong technical background in software engineering and system architecture
Experience managing or leading engineering teams
Ability to structure engineering work and maintain development velocity
Strong judgment in technical decision-making
Comfortable operating in early-stage environments
Clear communication and ability to work across teams
Our organization is very flat and our team is small, highly motivated, and focused on engineering and product excellence. All members are expected to be hands-on and to contribute directly to the company’s mission.
Code reviews and design reviews are expected for all meaningful changes. We discuss architecture openly, make decisions quickly, and ship frequently.
Product, ML, and engineering collaborate directly — there are no heavy handoffs between teams. Leadership stays close to technical work.
We favor clear ownership, simple architecture, and fast iteration. Engineers are trusted to make decisions and take responsibility for the systems they build.
If there appears to be a fit, we'll reach to schedule 3, but no more than 4 interviews.
Applications are evaluated by our technical team members. Interviews will be conducted via virtual meetings and/or onsite.
We value transparency and efficiency, so expect a prompt decision. If you've demonstrated the exceptional skills and mindset we're looking for, the process to offer may be shorter.
