Web App Full-Stack Engineer

Requirements

• Senior-level engineer with 5+ years of professional software development experience.
• Proven experience developing and maintaining production web applications.
• Strong backend development experience.
• Hands-on experience developing AI features.
• Practical experience working with large language models (LLMs).
• Practical experience with computer vision.
• C1 English level or higher.
• Hands-on experience with production web application development, AI feature development, Web APIs, software architecture, testing, and deployment.

We value sound technical judgment, independent execution, and the ability to solve complex engineering problems while delivering measurable product impact.

We are seeking a Senior Web App Full Stack Engineer to build and improve production web applications with a strong focus on backend systems and AI-powered capabilities. You will work across the stack, taking ownership of features from design and implementation through deployment and iteration.

• Design, implement, test, and maintain full stack web application features for production use.
• Build backend services and APIs that support reliable, scalable application functionality.
• Develop and integrate AI features using LLMs and computer vision techniques.
• Own technical delivery from problem definition through implementation, deployment, monitoring, and iteration.
• Investigate production issues, identify root causes, and implement durable fixes.
• Review performance data and use findings to improve application quality and user experience.

This is a full-time, 100% remote engagement. You will work directly with the client's small product team and founders on a live product, with real ownership of the application and the opportunity to make a measurable impact.

Upon successful completion of the initial contract, there is potential for long-term collaboration and stable, full-time employment, reflecting our long-term commitment to our team members.

Joining Niuro means becoming part of a global community dedicated to technological excellence and benefiting from strong administrative support infrastructure that enables you to focus on impactful work without distraction.

Desirable (not required)

• Experience with deploying and operating AI/ML-powered features in production (reliability, latency, and monitoring).
• Track record of improving system performance using production metrics and experiments.
• Experience collaborating with cross-functional stakeholders across design, implementation, and iteration.

Niuro is hiring for one specific, open position: a Senior Web App Full-Stack Engineer for a single client engagement. You will join the client's small product team, with direct access to the founders, and work on a live web application that is already running in production and actively evolving. The product combines a solid backend with AI-powered features (LLMs and computer vision). Your job is to own that application end to end: shipping new features, resolving bugs, and improving the product using performance data and user feedback. Niuro manages the hiring process and administrative support so you can focus on the work.
