Product Engineer · Full time role sought

I build products with AI that actually work.

I connect product framing, interface work and full stack implementation through to a verified state. AI accelerates the path while ownership stays with me.

Local First Desktop App

while.coffee

A local Tauri vault for therapy preparation, orientation and self organisation. Private content stays on device. Product logic treats crisis situations as a safety boundary rather than an engagement feature.

Approach

AI increases my speed. Responsibility stays with me.

I treat what is often called vibe coding as a controlled product process. Coding agents accelerate implementation while problem understanding, architecture, safety boundaries and acceptance stay with me.

01

Understand

I clarify the goal, users, constraints and the smallest meaningful moment of value.

02

Decide

I document consequential product and architecture decisions, including rejected alternatives.

03

Orchestrate

I split work across specialised agents while keeping context, interfaces and boundaries consistent.

04

Verify

I check production logic through tests, builds, browser QA and independent reviews.

About

Commercial thinking meets technical curiosity.

My path began in ecommerce. That is why I ask about utility, process and impact before I ask about features. Code is not an end in itself, but a tool for solving a problem completely.

I am looking for a team that values curious generalists, integrates AI seriously into product development and does not bind ownership to job titles.

I am looking for a full time Product Engineer role, especially in AI native teams building agentic workflows and modern web products. In a technical conversation, I am happy to walk through an architecture decision, a critical failure path and my route to a verified state.
