• # Senior Back-end Developer – Python

  * Position: Full time

  * Location: Cambridge, UK

  ## Position Summary

  We are looking for an experienced back-end web developer to join our

  engineering team in Cambridge. You will be working on the HP Wolf Security

  Cloud Service – a web-based platform to manage our security software products

  that are installed on end-user PCs (see https://www.hpwolf.com/). The job

  covers:

  * The API and UI back-end (Python, Django, Django REST Framework)

  * The background worker service / task queues (Celery, Dramatiq)

  * Container-based packaging (Linux, Nginx, PostgreSQL, Docker)

  * Supporting operational deployment using AWS (S3, ECS, RDS, etc.)

  * Integrations with other cloud systems (Elastic/Kibana, Salesforce,

     InterWorks, Azure, other internal HP systems)

  * Maintaining product compatibility for customers' self-hosted, on-premise

     servers (Windows, IIS, SQL Server)

  * Unit tests, Playwright/Selenium tests, automated installation tests, static

     code analysis, anything else we can have the CI system (Jenkins) do for us

  The HP Wolf Security Cloud Service is composed of several different services

  that serve various roles in the architecture.

  The HP Wolf Security Controller provides security policy and software updates

  for the endpoint security product installed on the client PCs. It also receives

  status, events and threat data from these clients, including malware traces

  which are used to produce interactive visualisations in the web-based UI and

  summarised in reports. The Controller is deployed at scale, both on-premises at

  individual corporate enterprises with tens of thousands of clients, and in the

  cloud across hundreds of AWS instances. We're continuing to scale further, while

  also adding support for new products and enhancing existing features.

  The HP Wolf Security Portal is the unifying service for customers accessing

  the capabilities provided by HP Wolf Security on endpoints. Integrating with

  different SSO providers (Azure AD, HP ID) for authentication, it enables

  self-service onboarding for entitlement to HP Wolf Security endpoint

  software. For small-medium businesses or consumers it provides a simplified

  license management and configuration portal, whereas for larger customers it

  provides integrated access to their own dedicated Controller. It has features

  to support partners and our HP support teams to help customers onboard and

  manage their HP Wolf Security products.

  There may also be an opportunity to work on other supporting cloud services

  where some make use of Go, along with others using our typical stack.

  ## Required

  * Proven experience working with Python for web applications

  * Successful experience of designing scalable web services

  * Experience in tuning and optimising SQL queries, indices and other

     techniques to get the best performance out of the DBMS

  * Understanding of HTTP, caching, performance tradeoffs

  * Understanding of web security issues and how to design to avoid them

  * Bachelor’s degree in Computer Science or equivalent

  ## Desirable

  * Experience designing and deploying cloud services at scale

  * Experience using distributed task queue systems, such as Celery
