Why Join Us?

We value engineers who treat code as a craft. You’ll have the autonomy to choose the right tools for the job, the environment of equality and open collaboration, the support to grow professionally, and plenty of tasks to challenge yourself.

Your Role at impact.com:

We are looking for a Senior Node.js Engineer who doesn't just write code but actually enjoys the craft of programming. We need a proactive problem-solver - someone who treats failing code as a captivating puzzle to be solved and fixed before it impacts the user experience.

Our core product relies on a sophisticated ETL (Extract, Transform, Load) engine that pulls data from a dizzying array of external sources.

If you can find fun in reverse-engineering a complex API, building a crawler that can dance around obstacles, or optimizing the pipeline so that it can handle massive volumes you’ll fit right in.

What You'll Do:

• Architect & Build: Develop robust, scalable integrations using Node.js and TypeScript.
• The ETL Engine: Maintain and optimize the core of the ETL engine to ensure resiliency, high throughput and data integrity.
• Data Scavenging: Design and implement crawlers and API consumers that interface with diverse external systems.
• Dev On-Call: Participate in a shared on-call rotation. You’ll monitor system health, respond to alerts, and perform "surgery" on production issues when things go sideways.
• Quality First: Always looking for ways to improve and ensure the quality of our data.
• Mentorship: Lead by example in code reviews and architectural discussions, fostering a culture of technical excellence.

Who You Are:

• Pro-active: You don’t wait for a spec to be 100% perfect if you see a way to make the system better today.
• Tech Obsessed: You actually care about the stack. You follow the latest releases, you have opinions on tools, and you’re always looking for a more efficient way of working.
• Resilient: You understand that in the world of third-party integrations, things are unpredictable and unreliable. You enjoy the challenge of building "self-healing" systems.

What You Bring:

• Language Mastery: Deep expertise in Node.js and TypeScript.
• Data Engineering: Experience building data-processing/streaming processes, handling large datasets, and managing data schema evolution.
• Observability: Good understanding of OpenTelemetry, all types of observability signals and experience working with them.
• Cloud Native: Hands-on experience with Google Cloud Platform (GCP) (GKE, KMS, Google Cloud Storage, Secret Manager).
• Testing Rigor: A "test-first" mindset with experience in frameworks like Jest, Vitest and Playwright.
• Collaboration: Good understanding of GitHub workflows (PRs, Actions, Issues)

Benefits and Perks: 

At impact.com, we believe that when you’re happy and fulfilled, you do your best work. That’s why we’ve built a benefits package that supports your well-being, growth, and work-life balance.
