DevOps Engineer

Technical Operations | London, United Kingdom | Full Time

Job Description

Who we are:

GlobalSign is the leading provider of trusted identity and security solutions enabling businesses, large enterprises, cloud service providers and IoT innovators around the world to secure online communications, manage millions of verified digital identities and automate authentication and encryption. Its high-scale PKI and identity and access management (IAM) solutions support the billions of services, devices, people and things comprising the Internet of Everything (IoE). The company has offices in the Americas, Europe and Asia.

What we are doing:

In London, GlobalSign is developing its HV identity platform, forming the core of GlobalSign’s current and future products. Written in Golang, our platform is a complex distributed system, exposed in a RESTful fashion and backed by PostgreSQL, MongoDB, RabbitMQ, ElasticSearch and dedicated crypto hardware. Designed to scale to the needs of IoE and major cloud deployments, it is capable of issuing billions of identities, with industry leading performance. Built to comply with existing web standards and compliance rules, it is capable of servicing any X509 certificate use case, for both public and private trust.

Who we’re looking for

We have an expert Infrastructure Engineering team here in London and are looking for an outstanding DevOps Engineer to help us redefine our DevOps pipeline, reducing the management and maintenance load on the team, and enabling fast but safe deployment of new services and scaling of existing ones.

You are constantly striving to improve life for both your customers and your team, proactively developing our systems, and automating wherever you can. You are passionate about delivering the best possible service, and building networks that use the latest technology to support this goal.

You are platform-agnostic, happy to select (and master) the right tool for the job, and able to justify the choice. We aim to standardise where we can, but ensuring we consolidate on the right system, rather than defaulting based on legacy inheritance, or simply following the latest trend.

You are familiar with the fundamentals of scripting and object orientated programming, and are able to learn new languages. You enjoy finding the most efficient way to automate tasks with re-usable code.

You enjoy getting to grips with a problem. Your inquisitive mind and methodical approach enables you to drill down into an issue, breaking it into consecutively smaller pieces until you can isolate and resolve the root cause.

You give respectful honest feedback, working constantly to improve yourself and help your team-mates, while considering (and accepting where appropriate) alternate, sometimes opposing, opinions.

You work hard to deliver highly available quality solution for everyone to enjoy.
