You will be joining us as a Software Developer in a new sprint team based in Cambridge and work with domain experts and customers of the service to enhance our popular bioinformatics software (BaseSpace) to the next level of its evolution. This will involve liaising with a variety of stakeholders to specify, design and implement core services and product-enhancing features in Illumina’s cloud platform.

We work using a flavour of Agile/Scrum and collaborate with our US colleagues using the Scaled Agile Framework (SAFe). As a developer, you would be expected to design, implement and iterate on software features, working as part of an Agile Scrum team.

With day-to-day activities spanning the whole development life-cycle, you’ll also work with the test engineers to identify opportunities to bolster the automated testing within the continuous integration system, and ensure you see your ideas through to completion. Illumina’s cloud platform makes heavy use of Amazon Web Services, including S3, EC2, CloudFront, RedShift as well as cloud/DevOps technologies like Docker and Ansible, so you’ll need to have a grasp of how to work with a cloud-based technology stack.

Most importantly you will have an opportunity to be part of multidisciplinary projects delivering products that make a difference to people’s lives!

About you:

At Illumina, we recognise that enthusiasm and an ability to think through problems are as valuable as experience with specific technologies.  The list below gives a flavour of the skills that would be useful in the role, but we are open to applications from bright enthusiastic candidates, even if you do not match all of them:

  • Software development experience in Java required
  • Full software-lifecycle experience: software requirements, design, implementation, testing and maintenance.
  • Cross-site and interdisciplinary working
  • Working within a software development team to achieve delivery of version releases according to planned schedules, and in compliance with a Quality Management System
Any of the following skills are also desirable:

  • Development on both Windows and Linux systems
  • Experience working with Amazon Web Services and DevOps practices
  • Experience of Agile SAFe
  • Preparation of software requirements and system analysis
  • Web application development (Angular.js)
  • Software quality standards
  • Automated software testing

Work on challenging projects with an inspiring team.

Strong Node.js, Ruby or Java; JavaScript & HTML5 required. React.js would be a bonus.

This is a permanent role.

We’re looking for passionate software engineers with a proven track record of delivering challenging software projects and would thrive in a forward thinking, progressive, company.

You will always strive to understand the latest and greatest, keeping a keen eye on developments in the world of software development, platforms, architecture and patterns. You will be tenacious and passionate about doing things the right way and building software that makes a difference to our clients and their users.

The tech

Our developers have the opportunity to work on a variety of projects across a wide range of industries and sectors that deliver real value for both our clients and their users

We lean heavily on open source and encourage our developers to contribute and be active, engaged members of the community. We also open source our own projects.

We don't dictate how you work at Red Badger, each team is totally autonomous and entrusted to make the right decisions.

As a Red Badger software engineer you will allow each solution to drive the technology choice, not the other way around. You will be technology agnostic and choose the right tool for the job.

Some of our favourite tech at the moment includes:

  • Git, Github
  • ES6, Ruby, Node.js, Go, Clojure,
  • React.js, Elm, Flow
  • Sass, CSS Modules, CSS-in-JS, PostCSS

While the above is our favourite tech we are pragmatic enough to choose the right tool for the job and frequently find ourselves working on projects with tech such as .Net and Java. We know not everyone has had the chance to work with our favourite tech so that shouldn't stop you from applying; above all we are keen to hear from experienced well-rounded engineers.

Job description

We currently have a frontend/backend split for development, where there’s a HTTP|REST API used for handoff between the two. As a backend developer, you generally produce REST APIs for consumption by the frontend team and provide 2nd line support. Most of the codebase is in PHP.

New projects tend to be created as Kubernetes microservices using PHP 7.x (or occasionally Java) and are automatically deployed through a Git push trigger via the CI tool. Legacy code tends to be more monolithic and have less test coverage. Your workload will consist of a mixture of new development and old code bases.

Projects range in size from less than a day to a few weeks in duration. You have flexibility to investigate and suggest new technologies for solutions to problems.

A “Typical Day”

You’re working Flexitime, so today expect to work roughly 9:30 to 3pm and then 7pm to 9pm this evening.

Today you’re working on a Kafka consumer which effectively takes data from a MySQL table and insert it into an ElasticSearch 5.6 cluster. You’ll need to write an ElasticSearch mapping schema, and unit / integration tests (using PHPUnit) for the code.

Mid morning, you see a support issue on Slack (as you’re on ‘support’ this week) where some customers are having trouble posting to a certain social network. After some investigation and checking various logs, you identify a possible solution, discuss it with the team and implement a change to the publishing code. Initially, your change is feature flagged to restrict it to an internal account and you deploy it for support to to verify it before wider roll out.

Every few days there’s a development conference call where progress and priorities are discussed.

Skills Required

  1. OO PHP
  2. Command line Linux (Debian)
  3. Git
  4. SQL (MySQL)
  5. Docker
  6. REST API development and usage
  7. PHPUnit

Technologies we use

You don’t need to be an expert at any of these; this is to give you an idea of what we use.

  1. ElasticSearch
  2. MySQL and Percona XtraDB Cluster
  3. Kafka + Debezium
  4. Beanstalkd
  5. Redis
  6. Kubernetes (GCP Container Engine)
  7. Codeship (CI)
  8. Git (GitHub)
  9. Google Cloud Platform
