Job description

Job Responsibilities

• Executes software solutions, design, development, and technical troubleshooting with ability to think beyond routine or conventional approaches to build solutions or breakdown technical problems
  

• Design and build clean, testable Python services and APIs; optimize for reliability and performance. Build maintainable UIs using React and modern JavaScript/TypeScript. Integrate LLM APIs and/or agent frameworks into real workflows and user experiences. Develop cloud-native systems using containers, microservices, and AWS (preferred).
• Work with PostgreSQL/Aurora: schema design, querying, and state/session management patterns. Write tests, debug issues, review code, and ship iteratively in a fast-paced environment.

• Leverages enterprise-authorized AI coding assist tools within the work environment to improve code quality, delivery speed, and productivity across complex deliverables (e.g., code generation/refactoring, unit test creation, documentation), while validating outputs through peer review, automated testing, and secure coding standards; contributes learnings and reusable patterns to improve broader team effectiveness.

• Applies knowledge of tools within the Software Development Life Cycle toolchain, including enterprise-authorized AI-assisted development and automation capabilities, to improve the value realized by automation.

• Produces architecture and design artifacts for complex applications while being accountable for ensuring design constraints are met by software code development

• Gathers, analyzes, synthesizes, and develops visualizations and reporting from large, diverse data sets in service of continuous improvement of software applications and systems

• Proactively identifies hidden problems and patterns in data and uses these insights to drive improvements to coding hygiene and system architecture
  Required qualifications, capabilities, and skills

• Formal training or certification on software engineering concepts and 3+ years applied experience

• Strong Python (clean architecture, testing, performance awareness), Solid React + modern JavaScript/TypeScript for functional, maintainable UIs. Cloud-native development experience: containers + APIs/microservices + at least one major cloud (AWS preferred).

• Hands-on experience building with LLMs and agentic AI (LLM APIs and/or frameworks such as Google ADK, LangGraph, or similar) production or real deployed work, not just prototypes.
• Working knowledge of relational databases (PostgreSQL/Aurora), including schema design and query patterns. Strong fundamentals: data structures, REST/APIs, Git, testing, debugging.

• Hands-on experience using enterprise-authorized AI-assisted software development tools within the work environment (e.g., for coding, test creation, troubleshooting, or documentation) with demonstrated ability to critically evaluate, validate, and refine AI-generated outputs for correctness, performance, and security.

• Understanding of responsible AI use in engineering workflows, including data sensitivity considerations, secure handling of inputs/outputs, and adherence to resiliency and security expectations; ability to guide peers on safe and effective usage within team practices.

• Overall knowledge of the Software Development Life Cycle

• Solid understanding of agile methodologies such as CI/CD, Application Resiliency, and Security
