Job Summary

The Senior DevOps Engineer position is within our development team, working closely with our project software teams and co-located client teams to support their build and testing infrastructure. Most of our projects use C++, cmake/qmake and the Qt framework libraries running on a variety of platforms. They also support mobile deployment on Android and iOS. A successful candidate would typically be involved with:

• Maintaining, upgrading and troubleshooting build system infrastructure, encompassing Git/Gerrit repositories, Jenkins pipelines and distributed builds using Incredibuild
• Assist with setting up and maintaining new build and testing servers using Ansible and Docker and look to improve the automation, resilience and scalability of these systems
• Develop monitoring and reporting systems for build performance and quality metrics.
• Maintaining code signing tools and developer accounts supporting deployment
• Help with Gitlab integration and issue tracker syncing tasks for our largest client

The engineer would also be tasked with working on automation efforts and internal tooling systems to streamline processes and reduce administrative friction, for example:

• a company web-based dashboard linking to various data APIs tracking code metrics, attendance, time allocations and the like
• support tools to pull timesheet and progress calculations from various sources and provide project managers and executives with useful reports
• web and database automation tools to store and track software/hardware license management and related company data when onboard/offboarding engineers

Further, the candidate would be encouraged to help Carallon develop a future DevOps strategy suitable for a growing software development house, making use of new technologies as appropriate. The role would suit an engineer well-grounded in DevOps best practice who is keen to develop their skillset and responsibilities further.

We offer a very friendly, flexible and supportive working environment, with an internal professional development programme and regular training. Our development team is close-knit and highly motivated with a keen interest in the products it creates. A successful candidate should be similarly minded working in the driven, focused environment required to bring original and ground-breaking products to market.

The role is a unique opportunity to contribute to engineering systems that will be used to create spectacular events ranging from televised award-shows such as the Oscars, to corporate events for the world's leading brands, to the biggest rock-and-roll tours.

Key Responsibilities

• Work with developers and QA engineers to address build system issues and improve system infrastructure to reduce application build times and bottlenecks
• Improve DevOps system resilience and automation through use of scripting and infrastructure-as-code
• Assist with Carallon build system integration with client systems as they arise (issue trackers, Gitlab, etc)
• Develop custom Java plugins for Jenkins and Gerrit to improve workflow automation
• Work on internal tool development to streamline department administration and efficiency (typically Python-based)
