About the role

Your Impact

  • Own features end-to-end: from technical design through launch to metric readout, operating with a high degree of autonomy
  • Design and build scalable backend systems that power growth loops — sharing flows, invite mechanics, notification pipelines, and onboarding infrastructure
  • Lead the instrumentation strategy for new features, ensuring the team has the data it needs to measure impact and iterate with confidence
  • Drive A/B experiments: define hypotheses, instrument correctly, analyze results, and translate findings into concrete product decisions
  • Raise the team's technical bar through rigorous code reviews, design feedback, and proactive documentation
  • Partner with product and data to define what success looks like before building starts — and hold the team accountable to it after launch
  • Identify systemic gaps and advocate for improvements that increase the team's velocity and reliability over time

Requirements

  • Bachelor's degree in Computer Science or a related field, or equivalent practical experience
  • 5+ years of backend software engineering experience, with a strong track record of shipping impactful, user-facing features at scale
  • Deep proficiency in Python for building and maintaining production systems at scale
  • Strong command of relational databases (MySQL or similar) and experience designing schemas and query patterns for high-traffic production workloads
  • Production experience with NoSQL and high-performance data stores such as DynamoDB, Cassandra, Redis, or Elasticsearch, with ability to reason about consistency, latency, and scalability trade-offs
  • Production experience with Kafka or similar distributed messaging systems, understanding operational trade-offs
  • Experience with AWS infrastructure (EC2, S3, DynamoDB, or similar) and reasoning about reliability and cost in a cloud environment
  • Hands-on experience with A/B experimentation, including rigorous design and drawing well-grounded conclusions
  • Defines success in terms of user outcomes and business metrics
  • Operates effectively in ambiguous environments: scopes loosely defined problems, builds alignment, and drives to closure
  • Communicates technical decisions clearly to engineering peers and non-technical stakeholders

Nice-to-Haves

  • Experience with Go or another high-performance compiled language
