Founding Engineer (Product/Fullstack)

Founding Engineer (Employee #1) — Full-Stack / Product

Company: Poera (by Kento Labs Inc.) 

Location: San Francisco, CA — Remote/Hybrid

Job type: Full-time

Stage: Pre-Seed (backed by a top-tier VC)

About Poera.ai

Poera.ai is building an all-in-one AI creation platform that empowers creators, marketers, artists, and filmmakers to turn imagination into visual reality. We're building the ultimate multimodal engine for creative workflows — a single platform where users can generate cinematic images, video, audio, 3D assets, and real-time interactive video.

Our founder is the former multimodal tech lead for Google Gemini and holds a patent in RAG technology. We're at the Pre-Seed stage: well-funded, extremely lean, and moving dangerously fast.

The Role

We're looking for our first Founding Engineer (full-stack / product-oriented). You'll work shoulder-to-shoulder with the founder to take our flagship product from 0 to 1.

This is a high-velocity, high-output startup environment. You'll have enormous autonomy, own core architecture decisions, and take full control of the product's technical direction. We're looking for a Strong Builder — someone who thrives in ambiguity and is hungry to build a category-defining AI company from scratch.

What You Will Do

• Lead 0-to-1 development: Partner closely with the founder to architect, build, and ship the core foundations of the Poera.ai platform from the ground up.
• Own the infrastructure: Design and scale our AI infrastructure, managing complex agentic workflows and large-scale model inference.
• Ship at extreme speed: Iterate at startup pace, integrating real-time video, 3D asset generation, and LLM capabilities based on user feedback.
• Optimize model inference and serving: Design and fine-tune high-throughput, low-latency model serving systems (quantization, caching, LoRA fine-tuning, and more).
• Shape the engineering culture: Establish the code standards, best practices, and technical foundation for the future engineering team.

What We're Looking For

• Experience: 3+ years of software engineering experience (or equivalent startup / indie-building experience).
• Technical stack: Strong command of cloud-native platforms (GCP), Next.js, and Postgres/SQL; highly fluent with AI coding assistants (Claude / Cursor / Codex); familiar with MCP (Model Context Protocol) and mainstream AI/ML infrastructure.
• Delivery track record: A history of independently shipping end-to-end products, complex features, or substantial side projects.
• Startup DNA: A pure love of building, an ability to thrive in uncertainty, and a desire for high-autonomy work.
• Systems thinking: You think in terms of whole-system architecture rather than isolated microservices, and you're comfortable designing for concurrency, high availability, and scale.

Bonus Points

• Strong product taste and user empathy, with experience in creative tools (e.g., Adobe Premiere Pro or node-based workflows).
• Experience deploying open-source video models (Wan 2.7, Vidu, Kling, Hailuo) or training custom foundation models.
• Familiarity with node-based AI systems such as ComfyUI or SwarmUI.
• Contributions to ML systems tooling (compilers, kernels, inference runtimes) or open-source infrastructure projects.

What We Offer

As Founding Engineer #1, you'll have the opportunity to shape our product from the ground up. We offer a competitive startup base salary plus significant foundational equity. You'll have unparalleled ownership over the project, a direct and lasting impact on the company's future, and the chance to build tools that redefine how the world creates content.
