We meet the customers where they are from Applicant Tracking Systems to communication tools such as Slack and Zoom.

* Use AI-powered development tools to accelerate coding, debugging, and automation workflows.
#### **Who you are**
* An experienced engineer with 5+ years in the field, including 4+ years building and maintaining production systems in TypeScript and Node.js.
* A technical leader with at least a year of experience guiding projects or mentoring teammates.
* Someone who holds a high bar for code quality, testing, and operational reliability.
* Comfortable using AI tools like Copilot, Cursor, or ChatGPT to move faster and ship better code.
#### **Even better if you have**
* Run temporal in production, and worked with Nest.js to build reliable, scalable services.
* Hands-on experience with AWS or similar cloud infrastructure, and familiarity with enterprise integration patterns and ATS platforms.
* Built internal tooling or automation powered by AI/LLMs to reduce manual effort and improve developer productivity.
#### **You’ll thrive in this role if**
* Designing complex systems excites you, and you deliver impact with every commit.
* Operational excellence and reliability are principles you care deeply about.
* Collaboration is second nature, you’ve worked across teams to drive meaningful outcomes.
* You hold yourself and others to a high bar of engineering excellence.
**Compensation**
* Base salary range: $150,000 – $172,000.
* This range doesn’t include bonuses, stock options, or benefits for which you will be eligible.
* Final offer may vary based on skills, experience, location, and other compensation components.
