Senior Infrastructure Engineer

Sinara Consultants are recruiting a Senior Infrastructure Engineer to join our in-house IT infrastructure team. If you want to pursue a career in IT infrastructure working within a software company serving the financial sector with technically literate colleagues, you might like to apply to join us as our Senior IT Infrastructure Engineer.

About the role

This is a varied and challenging role for an IT Infrastructure Engineer to work with our Head of Technical Operations and IT Director to manage and maintain the infrastructure described below. The Infrastructure Engineer role requires knowledge of system and application software, networking and hardware and so will suit someone with a broad enthusiasm within IT, possibly someone who is looking for a step up in their IT infrastructure career. Although this is not a support position, you will need to communicate both with Sinara’s own users and occasionally with external clients. Such contact will in general be with technically literate users. You will also have support from and provide guidance to the Junior IT Infrastructure Engineer.


Our development and operational activities require a significant IT infrastructure – in our office, hosted at a major London data centre, and also in the cloud. We use a wide range of technology, including Microsoft Windows, Linux, Hyper V, Active Directory, Microsoft Exchange, AWS, Azure, Kubernetes / containers and we make extensive use of SQL Server and PostGreSQL databases.

About you

You will have five or more years’ of relevant experience working in an IT Infrastructure role for a company using some or all of the technologies listed above, but essential to have some experience in cloud infrastructure.

You must be self-motivated, able to use your own initiative and thrive on learning new technologies and taking ownership of projects to achieve infrastructure objectives.

You should be someone who enjoys fixing things, building structure where it is lacking but can also be flexible where necessary to meet the changing needs of the company.

You are a practical person with a can-do, hands-on approach to new issues.
