Job Description

Job Requirements

  • 8+ years of experience designing and building backend systems in production, with a focus on consumer-scale applications.
  • Deep expertise in distributed systems and event-driven architectures (Kafka, Kinesis, SQS, etc.), including experience with idempotency, retries, and fault tolerance.
  • Strong command of an object-oriented programming language (e.g., Java, Kotlin, C#, Python, Ruby), along with experience working with APIs, databases, and caching systems.
  • Proven success leading complex, zero-to-one product development in ambiguous or fast-changing environments.
  • Demonstrated ability to influence product strategy through technical leadership and user-centric thinking.
  • Track record of building with observability and operational excellence in mind (metrics, logs, traces, alerting, etc.).
  • Active use of AI tools in engineering, with a forward-looking perspective on how AI is reshaping software development.
  • Exceptional communication and collaboration skills; able to align teams and advocate for high-impact solutions across functions.
