About the job
Join the Team Building the Future of AI-Powered Visual Creativity
Aurify is looking for a Senior Full Stack Engineer to work closely with our CTO and engineering team to build, scale, and continuously improve our B2C visual AI platform.
This is a hands-on senior engineering role for someone who enjoys building consumer-facing products end-to-end — from frontend UX to backend systems — working with rapidly evolving AI technologies, and solving challenging problems around performance, scalability, and user experience.
About Aurify
Aurify is a B2C platform where users upload a photo and instantly get back a high-quality AI video or avatar — no prompts, no editing, and no technical knowledge required.
We move fast, integrating the latest image generation, video synthesis, and digital human technologies. Our product lives and dies on output quality, speed, reliability, and seamless UX.

Quick Filter — Read Before Applying
This role is specifically for a senior full stack engineer who has built or contributed significantly to consumer-facing applications across both frontend and backend, ideally involving AI-generated images, video, avatars, media, or other content-generation experiences.
You should be equally comfortable building polished, responsive UIs and working hands-on with APIs, backend systems, databases, and cloud infrastructure.
Experience with AI/ML products is strongly preferred.
What You'll Own
Full-Stack Product Development
- Integrate image, video, avatar, and other generative AI APIs.
- Build end-to-end workflows for AI generation, processing, storage, and delivery — from UI to backend pipeline.
- Evaluate new AI models and APIs based on quality, speed, reliability, and cost.
- Help improve generation pipelines and troubleshoot production issues.
AI Integration
- Integrate image, video, avatar, and other generative AI APIs.
- Build workflows for AI generation, processing, storage, and delivery.
- Evaluate new AI models and APIs based on quality, speed, reliability, and cost.
- Help improve generation pipelines and troubleshoot production issues.
Architecture & Scalability
- Design and implement systems capable of handling increasing generation volume and user traffic.
- Improve application performance, reliability, and infrastructure efficiency across frontend and backend.
- Identify technical bottlenecks and propose practical solutions.
- Contribute to architectural decisions under the direction of the CTO.
Engineering Excellence
- Write clean, maintainable, and production-ready code across the full stack.
- Conduct code reviews when requested by the CTO.
- Debug complex technical issues across the entire application stack.
- Improve testing, monitoring, logging, deployment, and development workflows.
- Follow engineering standards and technical direction established by the CTO
What We're Looking For
Required
- 5+ years of professional software engineering experience, with demonstrated full stack ownership.
- Proven experience building and shipping consumer-facing web or mobile applications, both frontend and backend.
- Strong experience with modern JavaScript/TypeScript across frontend (React/Next.js) and backend (Node.js).
- Strong understanding of APIs, databases, authentication, cloud infrastructure, and scalable application design.
- Experience integrating and working with third-party APIs.
- Experience taking features from development through production, across the full stack.
- Ability to independently solve complex technical problems on both the client and server side.
- Strong communication skills and ability to work effectively in a remote startup environment.
- Comfortable working under the technical direction of a CTO in a fast-moving environment.
Strongly Preferred
- Experience building AI-powered consumer products.
- Experience with image generation, video generation, AI avatars, digital humans, or other generative AI applications.
- Experience working with APIs from AI model providers.
- Experience with cloud platforms such as AWS, GCP, or Azure.
- Experience with Docker, CI/CD, monitoring, and production infrastructure.
- Experience with high-volume media processing or content-generation pipelines.
- Experience optimizing AI/API infrastructure costs.
- Startup experience with significant hands-on engineering ownership across the stack.
You Might Have Worked On Something Like
- An AI avatar or digital human application.
- A consumer image-generation platform.
- An AI photo or video editing application.
- A photo-to-video generation product.
- A social or UGC platform with AI-powered features.
- A consumer SaaS product with significant API and media-processing infrastructure.
- A platform handling large volumes of user-generated images or videos.
You understand that building these products isn't just about making an API call. You have experience dealing with latency, reliability, generation failures, API costs, infrastructure, user expectations, and scale.
Tech Environment
Our technology stack may evolve quickly as the product grows, but experience with several of the following is valuable:
- JavaScript / TypeScript
- React / Next.js
- Node.js
- Python
- REST / GraphQL APIs
- PostgreSQL / SQL
- Redis
- AWS / GCP / Azure
- Docker
- CI/CD
- AI / image / video generation APIs
- Cloud storage and media processing
- Monitoring and observability tools
You don't need to know every technology listed above. Strong engineering fundamentals and the ability to learn quickly matter more than checking every box.
How You'll Work With the CTO
The CTO will own the technical vision, architecture, engineering strategy, AI technology direction, and overall engineering leadership.
As Senior Full Stack Engineer, your focus will be on hands-on technical execution and product development.
You'll be expected to:
- Take ownership of assigned technical projects and features, front-to-back.
- Translate product and technical requirements into working solutions.
- Make sound technical decisions within the established architecture and direction.
- Identify technical issues and communicate them proactively.
- Work closely with the CTO on implementation and technical priorities.
- Execute quickly while maintaining code quality and reliability.
- Collaborate with other developers to ensure smooth implementation.
- Take responsibility for the quality and performance of the code you ship, from UI to database.
What Success Looks Like
Within your first months, you'll be expected to:
- Become deeply familiar with the Aurify platform and architecture, frontend and backend.
- Take ownership of key areas of the product.
- Ship meaningful production features independently, end-to-end
- Improve platform reliability and performance.
- Help optimize AI generation workflows and infrastructure costs.
- Resolve technical issues efficiently across the stack
- Become a dependable senior engineering resource for the CTO.
Who Thrives Here
*You're probably a great fit if you're the kind of engineer who:
- Gets excited about new AI technologies and experiments with them.
- Can move between frontend and backend when a problem requires it.
- Enjoys building products that everyday users love.
- Doesn't need every task broken down into small tickets.
- Can move quickly without sacrificing engineering fundamentals.
- Think about both technology and the user experience.
We're looking for a builder — someone who can take a problem, figure out the technical path, and ship it.
