Required
Must be able to read, write, and speak in Mandarin and English.
Bachelor's degree in Computer Science, Computer Engineering, Electrical Engineering, or a related technical field.
2-8 years of professional software engineering experience, with a strong backend focus (e.g., building and maintaining services, APIs, and data pipelines in production). Prior Solutions Engineering, Forward Deployed Engineering, or Customer Success Engineering experience is a plus, but a software engineering foundation is required.
Strong backend fundamentals: you can write clean, working code on your own (Python, Node.js, or similar), design and integrate REST/webhook APIs, work with databases, and reason about system design, authentication, and error handling.
Able to pass a hands-on backend technical assessment (live coding or take-home) without relying on AI tools. We expect you to use AI to move faster, but you must understand and be able to explain, debug, and fix the code yourself.
Proven ability to debug complex issues across systems by reading logs, tracing requests, and isolating root causes in customer integrations.
Excellent communication skills: you can explain technical concepts clearly to both engineers and non-technical stakeholders, and work directly with customers to scope and build solutions with them.
Must be available to work some overlapping hours with our Pacific Time-based team and customers.
Preferred
Experience with AI, LLMs, or Voice AI.
Startup experience.
Enterprise customer experience.
Willingness to travel occasionally for customer launches or onsite work.
YOU MIGHT THRIVE IF
You enjoy solving technical problems directly with customers.
You like building alongside customers rather than just supporting them.
