Integration Engineer

Bubblehouse is a fast-growing custom and private loyalty platform. Headquartered in NYC, the entire team is fully remote and spread across US and Europe. We power loyalty programs for large brands, including household names. Companies are switching from other platforms thanks to the flexibility that we offer, enabled by our pace and technical excellence.

We’re looking for an integrations engineer. This role is perfect for a mid-to-senior level developer who’s detail-oriented to a fault, willing to figure out hard problems autonomously with little support.

You will use AI to its fullest, but will keep a very close eye on whatever that AI produces. As such, this role is less about coding, and more about figuring out what to build, how that best fits into the system, and why things are as they are, debugging edge cases, anticipating failure modes, talking to people, and plain old debugging.

Tech-wise, we’re running on Golang, and using custom database engine on top of local key-value stores, colocating the storage and compute on dedicated hardware servers, and reading data directly from mmap’ed pages of the database. Ever came across HN saying that one can run Twitter on a single machine these days? We’re doing that in production.

Zero lines of React, few third-party dependencies carefully vetted, every line of JavaScript manually written with respect and understanding of the web platform. We render HTML server-side like it’s 2005.

In this role, you will drive integration efforts end to end, from figuring out the technical spec based on client requirements, to actually building first-party integrations in code, to investigating any issues that arise in production.

After you get comfortable, you will also take client integration calls to guide them through this process and get involved with the spec earlier.

Looking for:

1. Around 5-10 years of experience; breadth and depth is a plus.

2. Detail-oriented above all. You don’t miss things. You’re the kind of person who will think about edge cases and subtle issues.

3. Autonomous work. You should not expect a lot of help from the team. We’ll give you a bit of mentoring, but day-to-day you need to be able to dig in and figure things out yourself with the help of AI.

4. Self-motivated about this specific work. You actually want to investigate, debug, and figure out what needs to be built. This is not a stepping stone to some “real” feature work — it is the work, and it’s interesting in its own right.

5. Willingness to figure out our world. There’s a lot set up on our end — codebase, conventions, tooling, database engine, deployment model. This isn’t about reading a book; it’s about figuring it out as you go.

6. Comfortable spoken English. You’ll eventually be on calls with clients, who’ll be expecting clear, polite communication — someone it’s comfortable to talk to.

7. Ability to overlap with 9am to noon New York time for coordination with the team and clients.

We give you a fast-paced environment where features ship in days, real ownership over a defined area of the product, and the chance to be the person who makes integrations actually work end to end. Our pay for this role is $70–110k/yr depending on experience and speed. All cash, with a possibility of equity in the future.

We are straightforward, driven, personal, and a little messy. We all care, and we expect you to care too.
