About this role

Are you ready to redefine the future of JavaScript development? Are you a seasoned JavaScript expert who gets a thrill from tackling complex challenges across the entire JavaScript ecosystem? Do you believe that AI can be a powerful partner in crafting elegant, high-impact code? If you're ready to leave the mundane behind and join a team that's shaping the tools used by millions of developers globally, we've got an opportunity for you at Sentry.

This isn't your typical Senior Software Engineer position. As a key member of our growing JavaScript SDK team, you'll be at the forefront of innovation, working on everything from our cutting-edge SDKs for the React, Next.js, Vue, Nuxt, Hono, NestJS, and beyond. You won't just be maintaining code; you'll be pushing the boundaries of what's possible in developer tooling across the full spectrum of the modern JavaScript framework landscape.

Responsibilities

• Dive deep into Sentry's extensive suite of JavaScript SDKs with a broad focus on framework support across the modern JS ecosystem (frontend frameworks like React and Vue; meta-frameworks like Next.js and Nuxt; server-side and edge runtimes like NestJS and Hono).
• Take end-to-end ownership: plan, implement, and ship code, including writing robust unit and integration tests and authoring clear documentation.
• Leverage AI tools to improve developer productivity and focus on solving complex problems.
• Represent Sentry in the open-source community and collaborate with organizations/committees such as TC39 and the OpenTelemetry SIG.
• Work directly with Customer Operations to triage and fix critical bugs and engage with the user community on GitHub and at conferences.

Requirements

• At least 5 years of experience as a Software Engineer, web developer, or a similar role.
• Deep expertise in developing web applications, libraries, or SDKs using TypeScript and JavaScript.
• Hands-on experience with two or more modern JavaScript frameworks such as React, Next.js, Vue, Nuxt, NestJS, or Hono, and a strong understanding of differences in rendering models, lifecycles, and runtime environments.
• Experience writing unit and integration tests and producing high-quality documentation.
• Exceptional written and verbal communication skills in English.
• Based in the Toronto, Canada area or excited about the prospect of relocating to Toronto.

Bonus points

• Familiarity with edge runtimes, server components, or hybrid rendering patterns across multiple frameworks.
• A history of contributing to or maintaining open-source libraries.
• Experience engaging with open-source committees or working groups.

Benefits

• The base salary range that Sentry reasonably expects to pay for this position is CAD $200,000 to $295,000.
• A successful candidate will be eligible to participate in Sentry's employee benefit plans/programs applicable to the candidate's position (including incentive compensation, equity grants, paid time off, and group health insurance coverage).
