About the Role

As a Senior Software Engineer, you will own the services that determine what millions of customers see in our apps, impacting both low-latency serving paths and the ranking and model integrations behind them. You will make architectural decisions, break down ambiguous problems into manageable steps, and build a successful team.

Responsibilities

  • Own and drive multiple features in recommendation and ranking services (Go and Python), from discovery through release and operation.
  • Drive architectural decisions, assess system lifecycles, fix architecture deficiencies, write RFCs and ADRs, and build consensus.
  • Break complex initiatives into milestones that deliver impact early and often.
  • Raise the bar on observability, scalability, cost efficiency, security, and code quality.
  • Resolve vulnerabilities within SLA and handle on-call incidents with quality post-incident reports.
  • Mentor less experienced engineers, participate in hiring, and partner with data scientists, ML engineers, and product managers.
  • Contribute to team development processes by recommending coding standards, frameworks, and tools.
  • Evangelize effective practices for team adoption.

Requirements

  • Strong backend engineering experience in Go and/or Python, building and owning production services.
  • Experience with stateful APIs, gRPC/REST integrations, and high-throughput request paths.
  • Experience with event streaming (Kafka, Flink, Pub/Sub).
  • Experience with infrastructure as code (Terraform).
  • Experience operating mission-critical services on AWS and/or GCP and Kubernetes.
  • Experience with observability, alerting, and on-call processes.
  • Experience recommending and evangelizing engineering best practices and tools.
  • Deep knowledge of team frameworks and tools, applied to critical decisions and problem-solving.
  • Track record of sound architectural trade-offs, explained clearly.
  • Ability to work autonomously on ambiguous problems, slicing them into releasable increments.
  • Ability to judge trade-offs by business impact.
  • Mentoring mindset.
  • Excellent written and verbal English communication skills.
