Full Stack Product Engineer Intern, Agent Native
About Mactores
Mactores is the agent-native AWS modernization firm. Most enterprise modernization stalls at pilots and handoffs; ours ships, production systems running, legacy retired, outcomes measured. Our delivery is built on Aedeon, the agent platform built by Mactores ' founders' sister company, Aedeon Inc. Aedeon absorbs the repetitive 60–70% of engagement work, discovery, mapping, validation, test generation, while forward-deployed engineers own architecture, judgment, and cutover. Mactores is Aedeon's flagship deployment partner: field delivery informs the platform roadmap, and the platform shapes how we deliver.
About Aedeon
Aedeon is the agent platform for enterprise modernization, built by Aedeon Inc., a separate product company founded by the same team that founded Mactores . Aedeon turns the systems already running a business applications, databases, data platforms, business rules, workflows into governed AI agents, grounded in a persistent Code Intelligence Graph of the customer's own code and verified through behavior-equivalence proof. Aedeon is delivered as a product, not a services engagement, and runs without mandatory forward-deployed engineers.
This internship puts you inside the platform side of Aedeon: you'll help build product features on the Aedeon frontend, working alongside senior full-stack engineers who will mentor you through the full delivery lifecycle, building features, writing test cases, and validating releases. You'll get hands-on exposure to a real product with real enterprise customers, not a sandbox project.
What you'll do?
Product development
-
Assist in designing, building, and maintaining features across the Aedeon frontend (React + Next.js) under the guidance of senior engineers.
-
Work with product managers, designers, and backend engineers to understand requirements and help take features from spec to shipped, tested release.
-
Participate in sprint planning, backlog grooming, and retrospectives, and start building a product-first perspective.
Learning release discipline
-
Learn how features are owned end to end — from development through deployment and post-release validation.
-
Practice breaking down tasks against sprint timelines and flagging blockers early.
-
Shadow how the team coordinates with DevOps and QA to keep releases clean and repeatable.
Testing and quality
-
Learn test-driven development: write test cases before code, under mentor review.
-
Help write test cases for features you work on — functional flows, edge cases, and regression scenarios.
-
Get exposure to AI-assisted tools for generating test coverage, and to automated test suites (E2E, integration, unit) wired into CI/CD.
Collaboration and documentation
-
Write clear, well-documented code and submit pull requests for review.
-
Document your work features, test plans, decisions in Confluence or equivalent, in a way others can follow without you in the room.
