Role

We are seeking a curious, motivated Associate Software Engineer to join our engineering team at Function. You will help design, build, and ship software that gives our members access to their health data in real time. Function is a highly AI-native engineering environment: our engineers use AI tools every day to write, review, test, and debug code, and to move faster without lowering the bar on quality. You'll work closely with experienced engineers who will mentor you, review your code, and help you grow quickly, while you take on real, meaningful work from your first weeks.

The ideal candidate is early in their engineering career, detail-oriented, eager to learn, and energized by a fast-paced environment. You are comfortable working with a variety of AI engineering workflows and see AI as a way to multiply your impact. This role is a great fit for someone who wants to build strong engineering fundamentals while contributing to a mission that matters.

Key Responsibilities

As an Associate Software Engineer at Function, you will

• AI-Native Software Development: Write clean, well-tested, maintainable code for well-scoped features and bug fixes, using AI coding assistants and agentic workflows as part of your daily process.

• Technical Problem Solving: Debug and resolve technical issues with support from your team. Break down problems into manageable pieces, and learn to investigate root causes using logs, monitoring, testing, and AI-assisted analysis.
• Quality and Engineering Practices: Participate in code reviews, write unit and integration tests, and follow our CI/CD, Agile, and documentation practices. Critically review AI-generated code for correctness, security, and maintainability before it ships, and take ownership of everything you commit. Help keep our data accurate and our systems reliable.
• AI Workflow Fluency: Learn and share effective ways of working with AI, such as prompting, providing context, using coding agents, and automating repetitive tasks. Help the team improve how we build with AI.
• Learning and Growth: Stay curious about new technologies and approaches. Seek feedback, take on stretch work, and apply what you learn to improve our platform.
