Lexer provides the data, tools and team to help retailers genuinely understand and engage with customers.
We’re a small team, handling big data, using the latest in technology. 


Lexer processes 5.5 billion points of data a day relying on technology like Elasticsearch, AWS, Terraform, and Buildkite – all with a very small team.
We’re looking for a DevOps/Infrastructure Engineer to help drive innovation, security, and stability as our business grows.

It’s a great opportunity for someone with enterprise IT experience who wants to break into a more agile, “start-up” style environment.

The full story:

Managing the infrastructure in a business processing these kinds of numbers requires diligence, action, and a whole lot of attention for detail.

At Lexer, we juggle these attributes each and every day – trying to operate a highly secure and stable environment, while running the latest tech, and of course, keeping the AWS bill to a minimum.

We’re looking for someone who can help our small team maintain our hundreds of servers and services, and improve many of our approaches across real-time data processing, search, global data distribution, rapid build processes, a near-zero-downtime status, and security.

We expect you to have:

  • Familiarity with AWS, EC2, Cloudwatch, S3, SQS, IAM and general AWS security
  • ICT security policy/procedures
  • Must have some Linux and Docker experience
  • Willingness to work with and learn various languages, python, shell, ruby, scala, golang
  • An understanding of Infrastructure as Code, or better, experience with Terraform
  • Enforcing security and integrity controls
  • System security and disaster recovery planning
  • Troubleshooting, support in diagnosing, resolving and repairing server-related hardware and software malfunctions
  • Familiarity with CI/CD tools
  • Monitoring network performance
  • Attention to detail, and personal pride in the quality of your work
  • An ability to work with developers to help build the best product possible
  • Develop strategies to minimise the risk of security threats

Any knowledge, or a passion to learn about:

  • Elasticsearch or Lucene
  • AWS ECS, Lambda, ASG, Aurora, Batch, and more
  • High-volume data platforms
  • Software development
