Full Stack Engineer, Intern Summer 2026

About AviaryAI

AviaryAI is a Y Combinator-backed startup building AI software for financial institutions and other regulated industries. We help banks, credit unions, and insurance organizations improve customer communication, internal knowledge access, and operational efficiency through practical, production-ready software.

Our team works across AI-enabled products, internal tools, workflow automation, integrations, and enterprise software systems. We focus on building technology that performs well in real-world environments where privacy, compliance, reliability, and usability all matter. Aviary’s broader product and engineering work spans customer-facing software, internal platforms, knowledge systems, and operational tooling that support AI products in production.

We are a startup, which means engineers here work with real ownership, real users, and real constraints. We care about building useful systems quickly, but also about making them scalable, maintainable, and trustworthy.

The Role

We’re hiring a Full Stack Intern to help build product and platform software at Aviary AI.

This role is ideal for someone who wants hands-on experience working across both frontend and backend systems in a fast-moving engineering environment. You’ll contribute to real features and internal tools that support our products, our customers, and our team’s day-to-day operations.

This intern will not be working directly on the core voice agent or model layer.

Instead, you’ll work on the software around it, the product surfaces, internal workflows, APIs, integrations, dashboards, and knowledge-based experiences that make the system usable and valuable in practice.

What You’ll Work On

Depending on your background and current team priorities, you may work on projects such as:

• Building frontend product features in our web application
• Developing internal tools and dashboards for engineering, operations, or customer teams
• Creating backend APIs and services that support product workflows
• Improving knowledge-base or document-based product experiences
• Building admin, configuration, and analytics interfaces
• Supporting integrations with customer systems and third-party platforms
• Improving testing, debugging, deployment, or developer workflow tooling
• Helping translate operational processes into clean, scalable software

In practice, this is a full stack product engineering role. You’ll help build software that people actually use, and you’ll see how product, engineering, and operations fit together inside a startup.

What We’re Looking For

Minimum Qualifications

• Currently pursuing a Bachelor’s degree in Computer Science, Software Engineering, Electrical Engineering, or a related technical field
• Junior standing or above
• Experience building software through coursework, internships, research, hackathons, or personal projects
• Comfort writing code across both frontend and backend environments
• Strong problem-solving skills and willingness to learn quickly
• Ability to work in a fast-paced environment with evolving priorities
• Strong written and verbal communication skills

Preferred Qualifications

• Experience with TypeScript or JavaScript
• Familiarity with modern frontend frameworks such as React or Next.js
• Familiarity with backend API development
• Experience with databases, cloud platforms, or systems integrations
• Interest in AI products, developer tools, workflow automation, or enterprise software
• Experience shipping projects end-to-end, even if small
• Comfort navigating ambiguity and figuring things out independently

What Success Looks Like

In this role, success means you can:

• Take a scoped problem and turn it into a working implementation
• Move comfortably between frontend and backend tasks
• Write code that is clear, maintainable, and production-minded
• Learn new systems quickly and contribute with increasing independence
• Improve the speed, usability, or reliability of the tools and features you touch

Why Join Aviary AI

• Work directly with a small, high-ownership team
• Build software used in real production environments
• Gain exposure to startup product engineering across frontend, backend, internal tooling, and integrations
• Learn how AI-enabled software is built for high-trust, regulated industries
• Get meaningful responsibility rather than purely sandboxed intern work
• Potential opportunity to grow into a longer-term role
