Software Engineer - Distributed Systems (London)

Do you fret over consistency versus availability guarantees? Do you love making complex systems easy to use, resilient, and scalable? That’s what we do! You might have heard of one of our open source projects like Paasta, data-pipeline, or Tron (check out our Github for more projects). Or maybe you’ve read our blog post (1) on how we monitor Cassandra at scale or watched our talk at MesosCon (2) about our distributed task runner.

The Distributed Systems group at Yelp designs, builds, and operates core infrastructure and critical services that all of Yelp’s feature teams rely on. We do everything from scaling our NoSQL datastore platform to storing petabytes of data, building systems to transport this data reliably in real-time streams, transforming these streams to build materialized views, and providing the computational infrastructure to run the batches and services that make up the website.

We also focus on building interfaces to these systems, making them easy to use while keeping them highly available and performant. Our systems power many critical applications including ads, search, transactions and revenue, spam detection, and machine learning, among others.

If this sounds like you, join the team that is the glue that connects Yelp’s feature teams to their underlying infrastructure.

First, Some Things You Should Know About Yelp:

  • Yelp was founded to help people find great local businesses like restaurants, dentists, hair stylists, and mechanics.

  • Yelpers have written more than 170 million reviews.
  • Yelp develops and maintains software to recommend the most helpful and reliable reviews. The software looks at dozens of different signals, including various measures of quality, reliability, and activity on Yelp.

  • Write code and documentation, participate in code reviews, and mentor other engineers
  • Support the infrastructure and software your team develops
  • Participate in a light on-call rota, handing off to US-based teams during the night time. No getting woken up in the middle of the night by a 3am page!

What We Are Looking For:

  • Strong knowledge of systems and application design with an understanding of operational and reliability trade-offs
  • Experience operating web-scale deployments of distributed systems, e.g., Kafka, Cassandra, Kubernetes, Elasticsearch

  • Strong understanding of operating systems, file systems, and networking
  • Experience using and operating Linux is ideal
  • Fluency in Python, Java, Scala, or a similar language (familiarity with more than one is a plus)

  • Exposure to cloud computing services like AWS, Azure, etc.
  • Experience working with and contributing to open source projects
  • Excellent written and interpersonal communication skills and willingness to uphold Yelp’s deeply held values

What We Offer:

  • Competitive salary with equity in the company, a pension scheme, and an optional employee stock purchase program
  • 25 days paid holiday initially, rising to 29 with service
  • Private health insurance, including dental and vision
  • Flexible working hours and meeting-free Thursdays
  • Regular 2-day Hackathons and weekly learning groups, always with interesting topics
  • Opportunities to participate in events and conferences throughout Europe and the US
  • Public transportation season ticket loan and £50 per month toward any exercise of your choice
  • Monthly personal development allowance
  • Central location, a fully stocked kitchen, adjustable sitting/standing desks, quarterly offsites, locally roasted coffee, happy hours, and more!
