The Opportunity:

We are seeking a motivated Associate Developer to join the Mighty Moose team, focused on API integrations and LLM-powered applications. Working under the guidance of senior developers, you will contribute to designing and implementing software solutions, collaborating closely with developers, architects, product owners and business stakeholders to deliver high-quality products and services.

What you will work with: Mighty Moose sits at the center of Liberty Mutual's Underwriting & Policy Platform, connecting the Underwriting Workbench, policy lifecycle management, and rating & pricing services across our US and Canadian operations under an enterprise API-first architecture. Our underwriting ecosystem also includes LLM-powered applications, such as D&O Copilot, built with Python and FastAPI, so this role spans both our core Node.js/TypeScript serverless APIs and these Python-based LLM services.

Agentic engineering, using AI coding agents, Model Context Protocol (MCP) tooling and other automation, is also a growing part of how we build and support software here.

Duties and Responsibilities:

• Contribute to the design, development, and testing of backend services and APIs on our AWS serverless stack (Lambda, API Gateway, DynamoDB), with guidance from senior developers. 
• Support the development and maintenance of Python/FastAPI services that power LLM-based applications such as D&O Copilot.
• Learn and apply agentic engineering practices and LLM-based solutions, including AI coding agents and automation tooling, as part of your day-to-day work.

• Collaborate with cross-functional teams to understand requirements and support delivery aligned with business objectives.

• Participate in code reviews, both giving and receiving feedback, to build strong coding practices. 

• Help troubleshoot and resolve technical issues, escalating complex problems to senior team members as needed. 

• Stay curious about emerging technologies and bring new ideas to the team. 
• Contribute to continuous improvement of our development practices as you grow in the role. 

Skills & Qualifications:

• Bachelor’s degree in Computer Science, Software Engineering, or a related field (or equivalent practical experience). 

• 0-2 years of experience in software development, including internships, co-op placements, or academic projects.
• Eagerness to learn and grow in a fast-paced, collaborative environment.
• Strong communication skills and the ability to work effectively in a team environment. 

• Foundational knowledge of TypeScript and Node.js; exposure to building APIs on AWS (Lambda, API Gateway, DynamoDB) is a plus. 

• Foundational knowledge of Python; exposure to FastAPI or similar frameworks is a plus.
• Familiarity with SQL/NoSQL databases and AWS fundamentals is a plus. 

• Exposure to Infrastructure as Code (e.g., AWS CDK) is a plus. 

• Familiarity with automated testing (e.g., Jest, pytest) or CI/CD pipelines is a plus. 

• Curiosity about agentic engineering and LLM-based solutions (AI coding agents, Copilot agent mode, MCP tooling) is a plus.
