Are you interested in working with the World’s leading AI-powered Quality Engineering Company? Ready to advance your career, team up with global thought leaders across industries and make a difference every day? Join us at Qualitest!
We are looking for a Full-Stack/Backend Engineer to join our growing team in Menlo Park, CA United States!
We are seeking a strong Full-Stack/Backend Engineer to help design, build, and operate backend services and product surfaces that power internal tools and AI-driven workflows.
This role is best suited for an engineer who is highly practical, execution-oriented, and comfortable working across the stack - from backend APIs and infrastructure to user-facing interfaces and mobile surfaces. The ideal candidate has strong hands-on experience in Python and TypeScript, and is comfortable deploying modern systems in cloud-native environments. Experience with GenAI systems, orchestration, and production deployment pipelines is highly valuable. Rust is a strong plus for performance-sensitive backend work.
Key Responsibilities:
Backend Systems & APIs
* Design, implement, and maintain backend APIs and internal services using Python.
* Contribute to service architecture, reliability, and maintainability for internal product workflows.
* Build integrations with internal and external systems, including data, storage, authentication, and service layers.
* Where appropriate, contribute to performance-sensitive backend components, with Rust as a plus.
Full-Stack Product Development
* Build and maintain user-facing interfaces and internal tools using TypeScript, React, and related modern web technologies.
* Design and implement polished internal product experiences with strong usability and practical workflow support.
* Partner on product implementation across desktop and web surfaces.
Mobile Development (Priority Area)
* Support or build high-priority mobile product surfaces across Android, iOS, and/or React Native.
* Help extend internal tooling and workflows into mobile-first experiences where needed.
* Collaborate on practical mobile UI architecture and implementation decisions.
Cloud, Deployment, and Infrastructure
* Deploy and operate services in modern cloud-native environments.
* Work with Kubernetes, Terraform, containers, and CI/CD pipelines.
* Support reliable service rollout, iteration, and operational stability.
* Contribute to deployment workflows, environment configuration, and developer velocity.
GenAI/AI Systems Integration
* Build and integrate end-to-end GenAI-enabled systems and workflows.
* Support model serving and inference pipelines, evaluation and monitoring systems, and orchestration workflows.
* Contribute to practical AI product integrations such as: Retrieval-Augmented Generation (RAG)
* Tool/agent orchestration
* Evaluation pipelines
* Workflow automation
* Model-backed product surfaces
Minimum Qualifications:
* Strong hands-on production experience building backend systems in Python.
* Solid proficiency in TypeScript and modern front-end development using React.
* Experience building and maintaining internal tools, APIs, or product workflows end-to-end.
Practical experience with cloud-native engineering, including:
* Kubernetes
* Terraform
* AWS CDK
* Containers/containerization
* CI/CD
* Hands-on experience building or integrating GenAI systems in real product or internal tooling contexts.
Familiarity with one or more of the following:
* Model serving/inference workflows
* Evaluation/monitoring pipelines
* Orchestration/workflow systems
* RAG pipelines
* Agent-style system integrations
Strong software engineering fundamentals, including:
* Code quality
* Testing
* Debugging
* Performance awareness
* Maintainable system design
Preferred Qualifications:
Experience building mobile applications or product surfaces for:
* Android
* iOS
* React Native
* Experience delivering GenAI systems to production or near-production environments.
* Strong familiarity with orchestration and workflow systems for AI-enabled applications.
* Experience operating Kubernetes and Terraform in production environments.
Experience integrating internal services with:
* Observability systems
* Security systems
* Storage systems
* Data pipelines
* Proficiency in Rust for high-performance or systems-oriented backend development.
* Strong product instincts and the ability to move fluidly between prototyping and production-minded implementation.
Ideal Candidate Profile:
* The strongest candidates for this role will likely demonstrate many of the following characteristics:
* Comfortable working as a generalist engineer across backend, infrastructure, and UI/mobile surfaces.
* Able to move quickly from idea to working implementation.
* Strong builder mindset with a bias toward practical execution.
* Excited by modern AI tooling and applied GenAI systems.
* Comfortable operating in an ambiguous but high-trust environment.
* Able to independently drive scoped work while collaborating closely with a small team.
* This is not a narrowly siloed role. It is best suited for someone who enjoys owning meaningful technical work across multiple layers of the stack.
