Senior Software Engineer, API

About Meshy:

Headquartered in Silicon Valley, Meshy is the leading 3D generative AI company on a mission to Unleash 3D Creativity by transforming the content creation pipeline. Meshy makes it effortless for both professional artists and hobbyists to create unique 3D assets—turning text and images into stunning 3D models in just minutes. What once took weeks and cost $1,000 now takes just 2 minutes and $1.

Our world-class team of top experts in computer graphics, AI, and art includes alumni from MIT, Stanford, and Berkeley, as well as veterans from Nvidia and Microsoft. Our talent spans the globe, with team members distributed across North America, Asia, and Oceania, fostering a diverse and innovative multi-regional culture focused on solving global 3D challenges. Meshy is trusted by top developers, backed by premier venture capital firms like Sequoia and Granite Asia, and has successfully raised nearly $400 Million in funding.

Meshy is the market leader, recognized as the No.1 in popularity among 3D AI tools (according to 2024 A16Z Games) and No.1 in website traffic (according to SimilarWeb, with 10 Million monthly visits). The platform boasts over 12 Million users and has generated 100 Million models.

Founder and CEO Yuanming (Ethan) Hu earned his Ph.D. in graphics and AI from MIT, where he developed the acclaimed Taichi GPU programming language (27K stars on GitHub, used by 300+ institutes). His work is highly influential, including an honorable mention for the SIGGRAPH 2022 Outstanding Doctoral Dissertation Award and over 2,700 research citations.

About The Role:

The Developer Platform team builds and runs the Meshy API, which is how developers, studios, and AI agents around the world put 3D generation into their own products, together with the MCP Server, CLI, plugins, and documentation that sit on top of it. The platform covers everything from a single 3D generation call to multi-step pipelines (texturing, rigging, animation) and agent workflows that run end to end without a human in the loop. A large share of Meshy's production traffic arrives through the developer platform every day and continues to grow rapidly as users adopt agentic and programmatic workflows at scale. The team works directly with internal model and infrastructure teams on one side and with developers and customers on the other, driving technical challenges cross-functionally on a day to day basis.

In this role you will help drive the technical engineering behind how the developer platform shows up to developers and agents. We are looking for a creative builder who treats our core API and developer tooling as a product: proactively identify issues, iterate on feedback, and iterate to make our API and developer platform best-in-class across GenAI tooling, especially with regards to developer experience and performance.

Basic information

• Job Type: Fulltime

• Location: Sunnyvale; CA

• Compensation: $150k - $300k per year

What You’ll Do:

In this role you will:

• Own the core systems behind the Meshy API and keep it secure, reliable, and performant as it scales.

• Drive the developer experience for new Meshy capabilities, from the API schema to the MCP Server to the CLI and docs, and keep the API and the web product in lockstep.

• Build with Meshy the way our developers do, from developer pipelines to coding agent workflows and turn firsthand feedback into better API structure

• Evolve the MCP Server, CLI, and agentic suite so coding agents can optimally integrate Meshy without a human in the loop.

• Contribute to the developer platform strategy and roadmap, including which surfaces and capabilities to invest in from an engineering perspective.

• Work directly with both developers in the Meshy community and Fortune 500 enterprises, shipping features, fixing issues, and rapidly turning feedback and usage data into improvements in the API and platform.

What We're Looking For:

• Have strong engineering fundamentals, are fluent in at least one of Go / Python / TypeScript, and can ship from design to production without hand-holding.

• Have shipped and operated a public API for a generative AI product (i.e. image, video, 3D, speech, or LLM), and have lived through versioning, deprecations, rate limits, long-running tasks, quotas and billing, and model version churn.

• Have built and operated high-traffic backend services in production, including databases, caching, queues, and container orchestration (we run Postgres, Redis, and Kubernetes on AWS).

• Have deep, hands-on experience using Claude Code, Codex, Cursor, or other coding agents to build and ship software.

• Have built directly with LLM APIs or MCP and can articulate what makes an API practically agent-friendly

• Have taken something from zero to one with real users, and can operate independently in a fast-paced environment with ambiguous requirements and goals.

• Are an engineer at heart, but are willing to lean into product thinking and decisions.

Nice To Have:

• Maintained official SDKs, a CLI, or an MCP server; published and versioned packages on npm or PyPI.

• Hands-on with OpenAPI tooling (spec linting, code / docs / SDK generation, contract testing).

• Familiarity with 3D asset formats (glTF / GLB, FBX, OBJ, USD) or creator workflows in Blender, Three.js, Unity, or Unreal.

• A track record of high-quality open source contributions: libraries, tools, or docs that other developers actually use.

Our Values:

• Brain: We value intelligence and the pursuit of knowledge. Our team is composed of some of the brightest minds in the industry.

• Heart: We care deeply about our work, our users, and each other. Empathy and passion drive us forward.

• Gut: We trust our instincts and are not afraid to take bold risks. Innovation requires courage.

• Taste: We have a keen eye for quality and aesthetics. Our products are not just functional but also beautiful.

Why Join Meshy?

• Opportunity to work with a talented and passionate team at the forefront of AI and 3D technology.

• Flexible work environment

• Opportunities for fast professional growth and development.

• An inclusive culture that values creativity, innovation, and collaboration.
