Fullstack Developer
About UpsellPlus
We help the largest 1% of Shopify stores to grow their revenue and AOV through product recommendations.
Opportunities for you
- No BS environment: Work alongside a dedicated team in a small, agile company where we move fast. We improve every day and have clear goals we’re working towards. Feel the progress and impact on customers every day.
- AI first: We're power users of AI internally to speed up development, CS and marketing. We expect you to do the same. The ever-evolving Shopify ecosystem encourages you to explore new technologies and optimize solutions—our core tech includes React, Node.js, Firebase and the latest Shopify API’s.
- Flexible work culture: Manage your own schedule in our remote and asynchronous environment. We rarely have meetings. You will be judged on your output. We meet every two weeks with the team to just hang out and play some games.
- Personal growth: We value individuality and offer a clear path for growth for your skills and goals.
What we’re looking for
- Proven experience as a Fullstack Developer on a small team.
- Knowledge of the Shopify ecosystem, apps, and API’s. If you’ve only worked on Shopify stores and themes before, this is not for you.
- Strong experience with React, Node.js, and Firebase.
- Well-versed in Cursor and Devin, and using AI to do more in less time.
- A ‘Get Stuff Done’ mentality and ability to be proactive, see problems and work through them independently.
- Strong technical English skills, both written and spoken.
The challenges ahead
- Innovate our flagship product: Make our product AI first, while being AI native internally. We expect high velocity and are open to experiment with tools.
- Customer obsession: Work with the CS team and the founders to solve customers problems and prioritize the roadmap.
- Make us a better team: Optimize our process and help us improve product velocity even further.

- Backend: Node.js, Firebase functions, Firestore, BigQuery
Infrastructure: Firebase hosting, Google Cloud Run, Sentry, Sendgrid

Why us?
We are dead set on becoming the #1 AOV growth platform for Shopify. We grew revenue 270% in 2023 and 100% in 2024.
We want to achieve that by earning our merchants ever growing piles of money with upsells. We’re focused on growth, but not at all costs. We’re bootstrapped, growing every month, and are profitable.
We operate as a truly remote-first, async-first company, allowing you to work when and where you are most productive.
We want someone who wants the challenge and work of being an early employee. And someone who cares about ownership and has pride over their work.
Beyond that, we would require someone who is:
- English speaking
- Overly communicative
- Has very high attention to detail
- Willing to work beyond a 9-5
Hiring process
- Intro call: An initial video call with our founder
- Experience deep dive: Questions about your previous work (written)
- Live coding project: A paid live coding project on an actual small feature our customers requested to get to know how you work
- References: We talk to 2-3 people that you worked with before
Position details
- Location: New York or remote
- Work Schedule: Flexible
- Compensation: We don't have a massive budget to pay huge salaries at the moment. We can offer a clear bonus system. If you want to build a company with us, come join us and I promise that you'll be on the ride of your life.
