Product Engineer (Full stack) @ Helpjuice (AI SaaS)

Full Stack Product Engineer
We're 100% remote, been that way since 2011.
About 20 of us, spread across the world, profitable, and building things we actually stand behind.
We build two products. Helpjuice is our knowledge base software, used by thousands of companies including Amazon, Hertz, and Virgin. Outlearn is our newer AI-powered chatbot, already resolving nearly half of every support ticket it touches (without a human ever stepping in).
Both are shipping fast, and we need someone who can build real, reliable software across the stack for both.
What you'll do
Ship features across the stack: Rails backend, JS frontend (on Helpjuice and Outlearn)
Own things end-to-end: you design it, build it, test it, and you're the one who explains why it works when someone asks
Read and improve code that already exists, not just write new code in a vacuum
Work directly with the team on what to build next and how to build it well
Debug production issues and actually get to the root cause, not just the symptom
Make calls on frontend vs. backend tradeoffs and defend them
What we look for
Real, reviewable code somewhere (a GitHub, a portfolio, something we can actually look at)
You can walk us through a recent project in detail: what you built, what your specific role was, what broke and how you fixed it
Real depth in both Rails and JS - not just "I've touched it," but strong on both sides of the stack
Comfort using AI to code faster (we do too) - but you understand and can explain every line you ship, because you're the one signing off on it
Our bar is high, and it's not about credentials or years of experience — it's about whether you can build things that work and stand behind them. If "walk me through this project" gets you a vague answer, or you can't show us any code, this isn't your seat.
Compensation & Timezone
We pay fairly and transparently, candidate-anchored to what you tell us you're worth - we meet or exceed your number within the band.
We're fully remote - but this position timezone is semi-flexible (European hours): 9am - 6pm, +/- 3 hours around that window working time window.
How to apply
Answer the questions below, we read every one. Applying takes about 15 minutes; we reply within 24 hours and hope you do too.
