About The Position

Fixify's Integrations Platform is both the framework and the ecosystem: the patterns, SDK, and abstractions our team builds, plus the integrations themselves that run on them across customer ticketing, identity, knowledge, and endpoint systems. We are heading toward hundreds of integrations authored by our team today, by FDEs and contractors against the SDK, and increasingly by AI agents working on top of a platform solid enough to keep that scale safe. We have reached the point where building the platform underneath all of that matters more than building any single integration.
When you've finished building an integration, are you already noticing what the platform should have given you?
At Fixify, every integration starts as a small failure somebody is feeling. A password reset that didn't go through before a meeting. A Jira ticket that landed in the wrong queue. An access request that's been pending since Tuesday. Behind each of those is a user who can't get into a tool they need, an analyst staring at a triage queue, a customer wondering why this part of their stack is silent. The integrations we build are invisible when they work and impossible to ignore when they don't. Our job is to build the kind that work. At the scale we are heading toward, the only way to get there is by building a real platform underneath them.
As a Senior Software Engineer on the Integrations Platform team, you would build new integrations end-to-end and contribute to the platform that supports them. You would spot patterns across integrations and pull them into shared abstractions so the next ten don't repeat the last one. You would work on more than the standard API-and-poll model: webhooks, callbacks, iPaaS bridges (Okta Workflows, Tines), and browser-driven flows where vendor APIs fall short. The vendor surface is messy. The work is interesting because the work is real.

Requirements

• A track record of building or operating integrations, data pipelines, or ingestion systems, especially at multi-tenant scale across many customers.
• At least 5 years of experience building scalable, observable SaaS systems.
• Strong fluency in TypeScript and Node.js, with working knowledge of AWS primitives or equivalents (Lambda, SQS, S3).
• Hands-on experience with RESTful API design, webhook patterns, OAuth flows, and rate-limit-aware client design.
• Code that the next engineer is glad to inherit: modular, documented, idempotent.
• A reviewer's instinct for pull requests, with the same care you bring to writing them.
• Fluency with AI coding tools (Cursor, Claude Code, or equivalent), used as a multiplier rather than a crutch.
• The confidence to say "I don't know yet, here's how I'd find out."

Nice To Haves

• Thrive knowing it’s an iterative experience and you’ll learn more from shipping then from reading all the docs.

Responsibilities

• Build new integrations end-to-end and contribute to the platform that supports them.
• Spot patterns across integrations and pull them into shared abstractions so the next ten don't repeat the last one.
• Work on more than the standard API-and-poll model: webhooks, callbacks, iPaaS bridges (Okta Workflows, Tines), and browser-driven flows where vendor APIs fall short.
• Utilize expertise in Typescript to contribute to both the back-end and front-end code bases of the platform.
• Constantly strive to refine and improve the code you inherit, not only the code you create.
• Approach challenges with a blend of technical skill and creative thinking.
• Be a self-motivated professional who finds and fills gaps, embraces a growth mindset, and makes our culture even stronger.

Benefits

• Endless opportunities to learn new things.
• Work that influences organizations globally and makes a tangible difference in how people connect and collaborate.
• A team that values every voice and learns from every challenge.
• Share the “why” behind every decision so you learn from our collective journey.
• Connect with users for direct visibility into how people use the integrations and how your changes impact their day-to-day lives.
