Go Jobs - September 2025

Fullstory provides privacy-preserving session replay and analytics for websites and mobile apps. Our session replays are nothing short of magical - they look almost like a video of the user's screen (with private details redacted) - and the combination with analytics creates eye-opening insights.

We have several roles open in engineering & product. The backend roles are going to be working with Go (golang), gRPC, Solr, BigQuery/BigTable, Kubernetes (K8S/GKE), and more on Google Cloud Platform (GCP), and then the fullstack roles add in TypeScript & React for the frontend.

We’re hiring a full-time, Senior Full Stack Engineer to join our first product pod and help bring our first venture to life. You’ll work alongside a product manager, front-end engineer, and back-end engineer, supported by a Principal Architect and the studio leadership team. You’ll have autonomy, clear ownership, and the chance to shape both the product and our technical foundations from day one. This is a hybrid role, 3 days a week based out of our Toronto office.

What We’re Looking For

- 5+ years of experience building full-stack web applications, ideally in startup or venture environments. - Strong proficiency in Python, particularly with modern frameworks like FastAPI or Flask. Experience in other backend languages (e.g., Node.js, Go) is a bonus, but Python is our primary stack. - Proficiency with modern frontend frameworks such as React and TypeScript. - Familiarity with cloud infrastructure (GCP preferred) and DevOps best practices. - Comfort working in high-ambiguity, high-velocity environments with a lean, collaborative team. - A builder mindset—you’re as comfortable iterating in code as you are thinking about product.

Update to our August post: Thank you for all the interest from HN! We have filled 2 out of the 3 open positions. We are now seeking for expertise in full-stack development.

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.

We’re again expanding our lean team of extremely experienced developers. Companies are switching from other platforms thanks to the customizations and flexibility that we offer, enabled by our pace and technical excellence, which we intend to keep for years to come.

Tech-wise, we’re running on Golang, and using custom data storage 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, almost zero 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.

Looking for:

1. Top to bottom understanding of the software stack, from the modern-ish web platform to CPU caches.

2. Thinking and problem solving outside the box. (We don’t _always_ go for unconventional solutions, but we do it often enough to require a person who can do justice considering the entire problem space at every step.)

3. Demonstrated ability and hunger to learn new things quickly. (Every month we’re doing things we have never done before.)

4. Broad experience across multiple programming paradigms, platforms and software stacks.

5. Demonstrated care for the software craftsmanship (which can take many forms).

6. Great spoken English, and ability to communicate 9am to noon in New York time zone.

We give you a literally fast-paced environment (with features delivered in days) where you need to solve very challenging problems with practical advanced technology, take on entrenched market leaders, and help entrepreneurs across small and large businesses delight their fans.

Send a plain text cover letter to andrey+hiring@bubblehouse.com. Help us see how you stand out. Summarize your experience. Link to 1–5 impressive things you’ve built and proud of, link to where we can see some of your code, include your portfolio/CV, describe the platforms and stacks you’re an expert in. How did you start programming? What are you most passionate about in technology? What are the most interesting or weird things you’ve done? What are your strongest held professional opinions? Please make your email easy to read, we’ll appreciate that.

(If you have applied before, no need to re-apply, we’ll reach out.)
