Senior Software Engineer, Core Developer

Overview

We built Bubble with a clear mission in mind: to empower everyone to create software. We believe anyone with an idea should be able to build it, so we’re making software creation accessible to everyone. Our AI visual development platform enables anyone, whether they’re first-time entrepreneurs or enterprise teams, to take an idea from prompt to fully-functional, scalable reality across web, iOS, and Android — all on one platform, all without writing or managing a single line of code.

We are the only full-stack, cross-device no-code platform on the market with over 5 million users in over 100 countries, Bubble is breaking down the barriers to entrepreneurship and innovation across the globe.

What we’ve achieved:

Our product is working, and we are thriving. Entire VC-backed companies have been built entirely on Bubble. After finding product market fit and 8 years of bootstrapping, we raised a $100 million Series A and we’re one of the fastest-growing companies in the New York tech ecosystem. You can build just about anything on Bubble — our community is living proof.

Mailead grew a $10k investment in a Bubble product into a $2M valuation, while Faceless.video went from 0 to $1M+ ARR in less than a year, among many other examples.

About the Core Developer Experience team:

The Core Developer Experience (DX) Pod is a new team dedicated to improving the productivity, quality, and satisfaction of engineers working on Bubble’s core product and monolith. Our mission is to modernize the developer environment, reduce friction in day-to-day workflows, and unlock sustainable long-term velocity for the entire Core org. We focus on the pre-deployment developer experience, with an emphasis on frontend-heavy improvements in the near term.

Our work includes upgrading tooling and libraries, migrating off deprecated frameworks, strengthening support for our internal design system, speeding up testing and bundling, and addressing technical debt that slows down product delivery. Some initiatives we drive directly, while others involve building standards, frameworks, and example implementations that empower other Core teams to adopt best practices. By enabling engineers to work faster and with more confidence, the DX Pod creates leverage across the organization and ensures that Bubble’s engineering culture can scale as our product and customer base grow.

About the role:

As a Senior Software Engineer on the Developer Experience Pod, you’ll lead technical projects that improve how engineers build, test, and ship code ’ll take ownership of complex initiatives, from shaping technical designs through execution, and ensure they deliver measurable improvements to developer velocity, performance, or satisfaction. You’ll work closely with the pod’s technical lead and engineering manager to prioritize initiatives, and collaborate with other Core teams to roll out changes that scale beyond the pod itself.

This role is hands-on but also highly collaborative: you’ll mentor teammates, set standards for high-quality code and maintainable architectures, and help establish best practices that raise the bar across Core engineering.

As a Senior Software Engineer for CoreDX, you’ll focus on:

• Migrating off legacy frameworks and introducing modern frontend tooling

• Upgrading shared libraries and improving support for our internal design system

• Reducing test suite runtime and improving reliability of developer-facing tests

• Optimizing the local development loop, including build, bundling, and hot reload times

• Investigating and resolving sources of frontend performance regressions in the Editor

• Defining standards and building frameworks that other Core teams can adopt to increase consistency and speed

About you:

• 7+ years of professional software engineering experience, with a history of delivering high-impact technical projects

• Strong proficiency with modern frontend frameworks (Type Script, Solid
  
  JS/React, etc.) and the ability to work confidently across the stack

• Deep experience with developer tooling — build systems, bundlers, testing frameworks, package managers, and CI/CD pipelines — and a passion for improving how engineers work day to day

• Pro…
