Product Support Engineer (Remote Internship)

About FlexyPe

FlexyPe is the full-stack infrastructure for eCommerce - powering identity, cart, checkout, and post-purchase experiences for 800+ D2C brands. We process 300 Crores+ GMV, have a 100M+ shopper identity network, and we're profitable and bootstrapped with a 15-person team. We're now entering our next growth phase and need someone who can sell the value to merchants who don't know they can get a better one yet.

We're small, scrappy, and building the future. If you thrive in chaos, love wearing multiple hats, and want to leave fingerprints all over a rocketship, read on.

Role Overview

We're looking for a Product Support Engineer to own the technical side of getting merchants live on FlexyPe. This is a hands-on engineering role where you'll run theme integrations, take merchants from setup to go-live, and be the technical fixer for issues our support and success teams escalate. You'll work directly with the tech team and founders - if you like solving real problems for real customers and shipping fast, this is your seat.

What You'll Do

• Own merchant go-lives - handle end-to-end technical onboarding: setup, configuration, and taking each merchant from integration to live.
• Theme & store integrations - implement and troubleshoot FlexyPe across merchants' Shopify themes, ensuring checkout, cart, and scripts work flawlessly.
• Resolve escalations on priority - be the technical point person for queries raised by the support and success teams; debug, fix, and close them fast.
• Debug across the stack - read logs, reproduce issues, trace problems across frontend, APIs, and integrations, and ship the fix.
• Improve the process - spot recurring integration issues and help build tools, scripts, or docs so they stop happening.
• Work with the tech team - escalate deeper product bugs cleanly, with the context needed to fix them fast.

What We're Looking For

• Strong fundamentals in MERN Stack and comfort with REST and GraphQL APIs - you can read someone else's code and debug live issues.
• Familiarity with Shopify (themes, Liquid, scripts, app integrations) is a big plus - if you've built or customized a Shopify store, tell us.
• A real debugger - someone who enjoys chasing a bug to root cause, not just patching symptoms.
• Clear communicator who can explain a technical fix to a non-technical merchant without losing them.
• Comfortable with the pace and ambiguity of an early-stage, founder-led team.
