  • Collaborate closely with Product, Design, and cross-functional Engineering teams to define and deliver impactful features.
  • Maintain and optimize APIs and infrastructure using Java, Kafka, Postgres, and AWS technologies.
  • Take ownership of end-to-end development, from breaking down requirements to implementation, testing, deployment, and monitoring.
  • Mentor junior engineers and contribute to the growth of engineering best practices across the team.

QUALIFICATIONS
  • Professional experience developing large-scale backend systems in a production environment.
  • Deep proficiency in building and maintaining RESTful APIs and working with relational databases (e.g., Postgres).
  • Experience with event-driven architectures and tools like Kafka or SQS.
  • Strong testing practices and clear documentation habits.
  • Ability to thrive in a fast-paced, iterative environment focused on growth and experimentation.
  • Proven collaboration skills across engineering, product, and data teams.
