About Inworld 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.

We are backed by investors such as Lightspeed, Section 32, Kleiner Perkins, Microsoft’s M12 venture fund, BITKRAFT, Founders Fund, and First Spark Ventures. Our technology is used by category leaders, including NVIDIA, Microsoft Xbox, Niantic, Wishroll, Little Umbrella and Streamlabs, among many others. Inworld has been recognized by CB Insights as one of the 100 most promising AI companies globally and has been named one of LinkedIn's Top 10 Startups in the USA.

About The Role 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, 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.

Your main focus would be evolving the web experience. This is a developer-centric experience for key journeys, such as:

• A TTS playground to try out premade voices or even clone your own voice in a few seconds
• A full observability suite (logs, metrics/dashboards, traces) for data generated by our @inworld/runtime package.
• And more!

Your core responsibility would be to evolve our web experience to be absolutely dialed in for developer journeys, both iterating on current journeys and introducing new ones.

The Key Challenges Are

• Shipping quickly. AI is evolving weekly, so there’s a ton of opportunity to be had. We want to move fast to capture those opportunities while they are fresh, full of potential, and exciting with our customers.
• Developer-focused web experience. Our web experience has to be productive and powerful for AI developers (not end-consumers), otherwise they may look elsewhere. This takes listening to customers and iteration as much as just shipping new features out the door. How to do this well is much harder than it seems.
• Great features, solid foundations. Beyond just shipping features, our web foundations need ongoing refinement. Whether it’s state, query handling, routing, hooks, auth, test coverage, etc, there is always room to be better at our basics. We need you to drive such improvements while delivering features on time.

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.

What You’ll Do As a Senior Frontend Engineer, your goal is shipping useful, high quality features quickly. The more you can own and drive projects, the better. That involves:

• Establishing prioritized feature scope: Collaborate with the PMs, engineers and leads to determine the biggest product needs to focus on now. This is not a one-way flow, please participate with gusto!
• Collaborating, executing, delivering, feedback: 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.

Expected Experience Must Haves

• Excellent programming skills and experience in JavaScript and TypeScript
• Experience developing full-featured React apps, using popular libraries such as React Router and React Query
• Experience with popular frontend tools and libraries (MUI, Emotion, PostCSS, React Testing Library, Playwright, etc).
• Excellent verbal and written communication skills, can collaborate and coordinate with other roles and engineer with ease, trusted and well-regarded teammate

Bonus Qualifications

• Familiarity with Cursor or other AI-assisted coding tools
• Familiarity with turborepo
• Experience building AI-centric web apps and familiarity with AI and ML concepts

Candidates must be based in the Vancouver, BC area or willing to relocate.
