mid-senior ai engineer - qe skilled.

In this innovative hybrid role, you will bridge the gap between advanced artificial intelligence development and modern Quality Engineering (QE) practices. Sitting at the sweet spot of 7 to 10 years of total software engineering experience, you will act as a core executor—developing AI-native applications while simultaneously building specialized tools, automation scripts, and EVALs frameworks to empower the broader QE community. This position is ideal for a full-stack developer who natively builds using AI frameworks (e.g., LangChain, LangGraph, MCPs, and advanced RAG architectures) and views software design through the lens of quality, standardization, and platform reliability.

Duration: 6-Month Contract (with high potential for extension)

Work Arrangement: 100% Remote



Advantages

100% Remote Flexibility: Enjoy full remote working autonomy from anywhere within the region.

Cutting-Edge AI & QE Fusion: Work at the forefront of AI development by building tools that directly shape how Quality Engineering and automation are executed across an enterprise ecosystem.

Hands-On Platform Impact: Own end-to-end features—from designing RAG pipelines and agent behaviors to deploying robust EVALs frameworks that test and validate AI model outputs.

Modern Developer Sandbox: Deepen your technical toolkit working with modern full-stack architectures, cloud-native AI services, and next-generation testing tools.




Responsibilities

QE Tooling, EVALs & Automation Leadership
QE Productivity Tooling: Design, build, and deploy specialized tools and utilities that enhance the day-to-day productivity and technical capability of the Quality Engineering community.

Systematic EVALs Frameworks: Architect and advance robust EVALs frameworks to systematically evaluate, benchmark, test, and validate AI platform outputs for accuracy, performance, and reliability.

Ecosystem Standardization: Define and establish unified standards for test case generation, test automation scripts, and QE technical specifications using AI-assisted SDET methodologies.

AI Engineering & Full-Stack Development
AI & Agent Architecture: Develop AI-driven features, engineer intelligent agent behaviors, and build Retrieval-Augmented Generation (RAG) pipelines utilizing LangChain, LangGraph, and Vertex AI (or equivalent AWS/Azure services).

MERN Stack Execution: Write clean, modular, and performant code across the full software development lifecycle utilizing MongoDB, Express, React, and Node.js / TypeScript.

API & Backend Integration: Build, integrate, and maintain high-performance RESTful APIs, web services, and database connections using Python and Node.js.

SDET & Automation Scripting: Write automated test suites using modern web testing frameworks (e.g., Playwright or Cypress.io) powered by AI capabilities.


Qualifications

Experience Level: 7–10 years of hands-on professional software engineering and quality development experience (explicitly focused on practical execution rather than high-level architecture).

Full-Stack Development (5+ Years): Active, full-lifecycle experience with the MERN Stack (MongoDB, Express, React, Node.js / TypeScript) alongside standard enterprise dev tools (Docker, Git, VS Code, npm/pip).

AI & Cloud Ecosystems: Hands-on experience developing AI capabilities, agent workflows, and RAG architectures within Google Cloud Vertex AI (or equivalent AI platforms on AWS / Azure). Direct experience with LangChain, LangGraph, or Model Context Protocols (MCPs) is essential.

Core Backend & Scripting: Strong proficiency in Python for backend service integration, API development, and data manipulation, with secondary exposure to enterprise backend environments like Java.

QE Pedigree & SDET Capabilities: Demonstrable experience in an active Quality Engineering or SDET role with a solid grasp of modern QA concepts, automated testing frameworks, and script development (prior experience with Playwright or Cypress.io is highly valued).

Soft Skills: Outstanding problem-solving skills, strong technical communication, and a proactive mindset focused on empowering peer developers and quality engineers.



Summary
If you are a tech-savvy Software Engineer who pairs an absolute command of full-stack MERN development and modern AI frameworks (Vertex AI, RAG, LangChain) with the Quality Engineering pedigree required to build enterprise EVALs and automated testing tools, this 100% remote 6-month contract is an outstanding opportunity. Bring your hands-on execution mindset, AI scripting precision, and collaborative team focus to our client's growing engineering group today!
