• At least 6 years of practical software engineering experience, ideally in fast-moving, high-growth, and technically complex environments.
• Evidence of operating at Staff level, including architecture ownership, team mentoring, and influence over technical direction across multiple squads or projects.
• Strong grounding in cloud infrastructure and APIs, with preference for AWS, Node.js, and REST or GraphQL.
• Ability to collaborate effectively with both technical and non-technical stakeholders and convert complex needs into executable plans.
• Proven experience handling ambiguous, complex problems end-to-end while delivering strong outcomes.
• A product mindset with attention to reliability, scalability, and the real-world impact of technical choices on users.
• Genuine interest in AI and enthusiasm for building standout products in this space.
• Regular use of AI-assisted coding tools and awareness of current developments in the field.
