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.

• →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.

• 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.

• 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 themyy.
• Cloud Native: Hands-on experience with Google Cloud Platform (GCP) (e.g., 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)
