This core platform team focuses on enabling rapid innovation by developing and maintaining foundational components that support our broader engineering organization.

Drive Innovation: Collaborate with cross-functional teams to identify opportunities to enhance the developer experience and introduce new services that accelerate product development. Enable Engineering Excellence: Define and implement best practices in software engineering, CI/CD, and observability. Optimize Performance: Analyze and enhance system performance, ensuring low latency, high throughput, and minimal downtime. Participate in On-Call Rotation: Ensure the reliability and uptime of mission-critical services by participating in on-call duties and responding to incidents as needed. Minimum Qualifications: 5+ years of professional software engineering experience. Strong proficiency in backend programming languages (e.g., Go, Python, Java, or similar).

Prior experience in a fast-paced environment. Proficiency with cloud platforms such as AWS or GCP.
