Senior NodeJS Engineer - USA

Inworld AI • Mountain View, CA

84d • $150,000 - $250,000

About The Position

At Inworld, we believe the processes of building, scaling, and evolving applications are monsters that consume value before it can reach users. Our mission is to solve evolution and transform static software into AI systems that autonomously evolve to better serve their users. We are building an intelligent runtime to conquer these monsters and make this vision a reality. This summer, Inworld launched a new platform for consumer AI applications, and we're looking for an ambitious and capable Senior Frontend Engineer to join us and take this platform even farther. The core of this platform is the @inworld/runtime NPM package for Node-based AI applications, which utilizes our TTS, LLM, and other APIs. Additionally, there are cloud services for features like dynamic A/B experiments, and a web experience to tie it all together. As a Senior NodeJS engineer, you would contribute significantly to the @inworld/runtime package. It has a unique blend of challenges that should pique your interest: The core of the Runtime is written in C++, so what is the best way to interop with this code? Even though the core is written in C++, there are still challenges on the NodeJS side regarding streaming, concurrency, and high-end scale and performance. Providing a first-class, idiomatic developer experience (typing, API ergonomics, best practices, modern libraries, etc). This is an IC-focused role. We are looking for someone who loves direct technical contribution, and there is plenty of scope to go around.

Requirements

• Excellent programming skills and experience in JavaScript and TypeScript
• A solid grasp of NodeJS fundamentals: events, the event loop, streams, async, etc.
• Excellent verbal and written communication skills, can collaborate and coordinate with other roles and engineer with ease, trusted and well-regarded teammate

Nice To Haves

• Comfortable with C++ programming.
• Experience with Node interop with C++ code via the Node API.
• Familiarity with Cursor or other AI-assisted coding tools
• Experience building AI-centric web apps and familiarity with AI and ML concepts

Responsibilities

• Establishing prioritized feature scope: Collaborate with the PMs, engineers and leads to determine the biggest product needs to focus on now.
• Collaborating, executing, delivering: This is the core of the building loop. We aim to optimize for both speed and quality, despite it being decidedly non-obvious how to manage that tradeoff exceptionally well.
• Reflecting and driving improvements: Advocate for and realize foundational improvements, even while staying busy with feature work.

Benefits

• Equity and benefits included in total compensation.
