Sr Fullstack Developer Jobs in Allen, TX (NOW HIRING)

Hi All,

Good Morning,

Immediate and urgent need for the below requirement.

Title: Senior SDET / QA Automation Engineer (Agentic AI & Full-Stack)

Location: Dallas, TX – In-person interview is mandatory

Duration: Long Term

Need strong Python and AWS Bedrock experience

Summary:

We’re looking for a Senior SDET with strong fullstack engineering skills, deep experience in backend and servicelevel development, and the ability to build scalable test application in Python or Java. This role blends frontend and backend development, cloudnative testing, and AI-augmented quality engineering with a heavy focus on building and deploying autonomous, multi-agent frameworks, tool-calling mechanisms, and complex agentic workflows using Amazon Bedrock and modern LLMs.

Key Responsibilities:

·         Build and maintain automation frameworks for API, microservices, frontend UI, and integration testing.

·         Develop internal tools, SDKs, and test harnesses that improve developer productivity and system reliability.

·         Contribute to frontend development using modern frameworks such as React, Angular, or Vue, ensuring testability and accessibility.

·         Contribute to backend development of microservices, APIs, and distributed systems using Python or Java.

·         Architect CI/CDready test pipelines integrated with AWS cloud infrastructure (Lambda, ECS/EKS, S3, CloudWatch, DynamoDB).

·         Implement AIaugmented testing workflows using Amazon Bedrock for automated test generation, log analysis, and anomaly detection.

·         Build performance, load, and resilience testing strategies for both frontend and backend systems.

·         Collaborate with engineering teams to design testable architectures, enforce quality gates, and improve observability.

·         Drive rootcause analysis for production issues and build automated regression protections.

·         Mentor engineers on automation, code quality, and AIassisted testing best practices.

·         Architect, build, and maintain autonomous multi-agent testing workflows, enabling agents to self-heal test code, discover edge cases, and reason through end-to-end user journeys independently.

·         Implement advanced AI patterns including multi-agent orchestration, vector embeddings for test-state memory, tool calling, and human-in-the-loop validation mechanisms.

·         Establish strict evaluation and guardrail frameworks to measure agent accuracy, hallucinations, and performance degradation in production-grade testing tools.

 Required Qualifications:

·         10+ years as an SDET, Software Engineer, or FullStack Developer.

·         Strong coding skills in Python or Java with productiongrade engineering experience.

·         Handson frontend development experience (React, Angular, Vue, or similar).

·         Handson backend development experience with APIs, microservices, and distributed systems.

·         Expertise in API testing, contract testing, and servicelevel automation.

·         Experience building automation frameworks from scratch.

·         Strong understanding of CI/CD pipelines and automated quality gates.

·         Experience with AWS services (EC2, Lambda, S3, IAM, CloudFormation/Terraform).

·         Experience integrating or building solutions using LLMs or Amazon Bedrock.

·         Agentic AI Experience: Hands-on experience building and deploying production-ready agentic applications or multi-agent workflows.

·         AI Orchestration Frameworks: Deep familiarity with agentic frameworks such as LangChain, CrewAI, AutoGen, or LlamaIndex.

·         Advanced AI Patterns: Solid understanding of LLM reasoning patterns, retrieval-augmented generation (RAG), function calling/tool execution, and agent memory management.

·         Familiarity with containers (Docker) and orchestration (Kubernetes).

Preferred Qualifications:

·         Experience with frontend automation tools (Playwright, WebdriverIO).

·         Experience with distributed tracing and observability tools (CloudWatch, Datadog, OpenTelemetry).

·         Knowledge of performance testing tools (k6, Gatling, Locust).

·         Experience with eventdriven architectures (Kafka, SNS/SQS).

·         Background in security testing or chaos engineering.

·         Contributions to internal or opensource testing frameworks.

·         Soft Skills

·         Strong communication and ability to influence engineering teams.

·         Passion for automation, developer experience, and AIdriven quality engineering.

·         Ability to lead initiatives and drive quality strategy across teams.
