Full Stack 

Target Profile 

We are seeking an AI-native Full Stack Software Engineer who embraces AI as a core engineering capability. The ideal candidate is a cloud-native software engineer who leverages AI throughout the engineering lifecycle to accelerate software delivery while maintaining ownership of software quality, security, and maintainability. 

This engineer thrives in an AI-Assisted (Agentic) Software Development Lifecycle (ASDL), contributes within a specification-driven engineering environment, and continuously seeks opportunities to automate engineering work and improve developer productivity. 

Position Summary 

The Software Engineer designs, develops, tests, deploys, and supports scalable cloud-native software solutions. Working closely with Product Management, Systems Engineering, and Solution Architecture, this role owns features end-to-end—from engineering specifications through production deployment—delivering secure, reliable, and maintainable software. 

Responsibilities 

  • Design, develop, test, deploy, and support full-stack applications using Java/Spring Boot, Vue.js, and Python/FastAPI. 

  • Collaborate with cross-functional teams to refine engineering specifications and deliver high-quality software solutions. 

  • Build and operate cloud-native applications on AWS using Docker, Kubernetes, and Infrastructure as Code. 

  • Develop secure, scalable APIs and software following engineering standards and best practices. 

  • Apply AI throughout the AI-Assisted (Agentic) SDLC to accelerate implementation, code review, testing, debugging, and documentation while validating all AI-generated outputs. 

  • Contribute to engineering automation, continuous improvement, and AI-enabled development practices. 

Minimum Qualifications 

  • Bachelor's degree in Computer Science, Software Engineering, or a related technical field. 

  • 3–5 years of experience developing cloud-native software applications. 

  • Proficiency in Java/Spring Boot, Vue.js, React, Angular, PostgreSQL and Python/FastAPI. 

  • Experience with AWS, Docker, Kubernetes, and Infrastructure as Code (Terraform, CloudFormation, CDK, or equivalent). 

  • Strong understanding of REST APIs, modern software design, Agile development, and engineering best practices. 

  • Demonstrated experience working within an AI-Assisted (Agentic) SDLC, using AI to generate production-ready code, validate automated tests, identify and remediate defects, and improve software quality while exercising sound engineering judgment. 

Preferred Qualifications 

  • Experience developing microservices and distributed systems. 

  • Experience with GCP or multi-cloud environments. 

  • Experience with CI/CD and DevOps practices. 

  • Experience with Spec-Driven Development or specification-first engineering. 

  • Experience creating AI agents, engineering automations, or AI-enabled developer workflows.
