Build and maintain RESTful and WebSocket APIs using robust version control and resource-based architecture.

Collaborate with backend teams to design and implement scalable APIs following RODL principles.
Job Requirements:

5–10 years of experience in frontend engineering (3+ years considered for outstanding candidates).
-
Previous experience in fast-paced Series B+ startups, such as Stripe, Scale AI, Databricks, or DataRobot.
-
Demonstrated ability to build complex and scalable user interfaces with pixel-perfect implementation from Figma designs.

Proficiency in SQL (MySQL) and NoSQL (e.g., DynamoDB, DataStore, Redis) databases.
-
Experience with CI/CD pipelines, preferably using AWS/GCP with Docker.
-
Strong understanding of Git workflows, including version control using GitHub.
-
Ability to thrive in a startup environment with fast-paced changes and uncertainty, and willingness to work long hours when needed.
