You will contribute to building modern data- and AI-enabled applications, with an AI-first mindset—including the ability to leverage prompting techniques, LLM-driven workflows, and human-in-the-loop patterns to accelerate delivery and improve user outcomes while meeting strong security, control, and quality standards.
Job Responsibilities

Participates in the design and development of scalable and resilient systems using Python, SQL, React, AWS and other technologies to contribute to continual, iterative improvements for product teams
Executes software solutions including design, development, and technical troubleshooting across the full stack where needed
Partners with internal clients for requirements gathering, troubleshooting, and delivery of tools that enable better strategy, decisioning, and risk/cost management
Creates secure, high-quality production code and maintains services and algorithms that run reliably with appropriate upstream/downstream systems
Produces or contributes to architecture and design artifacts for applications while 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
Identifies hidden problems and patterns in data and uses these insights to drive improvements to coding hygiene, data quality, and system architecture
Contributes to software engineering communities of practice and events that explore new and emerging technologies, including modern AI engineering patterns
AI-first / prompt-oriented development responsibilities (embedded into delivery):
- Designs and implements LLM-enabled features (e.g., summarization, extraction, Q&A, reasoning assistants) with attention to reliability, latency, cost, and user experience
- Practices prompt-oriented development: iterating on prompts and system instructions as first-class artifacts, using versioning, test cases, and measurable evaluation criteria (quality, groundedness, safety)
- Implements patterns such as retrieval-augmented generation (RAG), tool/function calling, workflow orchestration, and human-in-the-loop review where appropriate
- Builds evaluation and monitoring approaches for AI features (automated checks, regression tests, guardrails, observability) and continuously improves quality based on production feedback
- Applies secure engineering practices to AI-enabled systems, including data minimization, access controls, safe handling of sensitive information, and resilience against prompt injection and misuse
- Adds to team culture of diversity, opportunity, inclusion, and respect
