Software Engineer-AI Platforms

Position Description

The Flex platform helps clients develop a comprehensive compliance program, leveraging technology to instill a culture of safety and maintain a productive workplace. The platform combines features tailored to the needs of our clients' businesses, including audits and inspections, incident management, flexible training, and reporting and insights.

As a member of our development team, the Software Engineer - AI Platform works across the full stack to deliver modern, AI-powered product functionality. You will build user-facing features in the Flex web application and the backend services, APIs, and LLM workflows behind them, so clients can keep their teams safe and manage risk.

This role suits an engineer with 2-3 years of professional experience who has shipped production features end to end and has hands-on exposure to LLM-based applications. You will own well-scoped features, work closely with senior engineers on architecture and AI integration patterns, and grow your depth in agentic workflows, MCP integrations, and evaluation practices.

Knowledge, Experience, Requirements:

Required

• 2-5 years of professional software engineering experience, including shipping production features across frontend and backend
• Proficiency in Node.js and TypeScript/JavaScript
• Experience building responsive web UIs with a modern framework such as React, including state management and API integration
• Ability to build and consume well-typed REST or GraphQL APIs in Node.js and TypeScript, with sound handling of authentication, error handling, and data transformation
• Hands-on experience building at least one application or feature using large language models via platforms such as AWS Bedrock, OpenAI, Anthropic, or similar
• Working understanding of tools, function calling, and agents, and how they let LLM systems take action against existing APIs
• Practical experience with prompt engineering and iterating on prompts to improve output quality
• Familiarity with Retrieval-Augmented Generation (RAG) concepts, embeddings, and vector-based search
• Comfort working in an AI-first development environment, using AI tools for code generation, refactoring, test creation, and documentation, and reviewing their output critically
• Experience working with relational databases and writing efficient queries
• Solid grasp of data structures, algorithms, and fundamentals of system design
• Good debugging skills across the browser, server, and network
• Experience writing unit and integration tests and working with CI/CD pipelines
• Clear communication and collaboration skills in an agile, team-based environment
• Bachelor's degree in Computer Science, Engineering, or a related technical discipline preferred, or equivalent practical experience

Nice to have

• Exposure to building or consuming Model Context Protocol (MCP) servers or similar AI integration layers
• Experience with LangChain, LangGraph, or similar orchestration frameworks
• Familiarity with LLM evaluation approaches, guardrails, or output monitoring
• Experience with AWS services (e.g., Lambda, ECS, S3) or another major cloud provider
• Exposure to observability tooling such as Datadog or CloudWatch
• Interest in or exposure to EHS, compliance, or safety software

Success Criteria:

• Delivers well-scoped, production-ready AI-powered features end to end, from UI to backend service, with solid test coverage and minimal rework
• Builds intuitive user experiences that present LLM outputs clearly, including loading states, error states, and ways for users to review or correct AI-generated results
• Implements LLM-driven workflows using services such as AWS Bedrock and LangChain, following patterns set by senior engineers
• Contributes to MCP servers and tool integrations that expose existing APIs to AI systems, with appropriate authentication, input validation, logging, and failure handling
• Applies prompt engineering techniques to improve accuracy and consistency, and uses evaluation results to measure improvements
• Implements guardrails and monitoring for LLM outputs as defined by the team's standards
• Validates and refines AI-generated code before submitting it for review, and owns its quality
• Breaks down defined product requirements into clear tasks and estimates, and raises ambiguity early
• Communicates progress, blockers, and tradeoffs clearly to engineering peers and product partners
• Participates actively in code reviews, both giving and receiving feedback constructively
• Shares useful AI workflows and learnings with the team through documentation and internal discussions
• Steadily grows ownership, moving from scoped features toward larger components and system-level design
• Contributes positively to team culture by collaborating effectively and fostering continuous learning
