Rothstein Recruitment

.NET developer in financial services

In short

Senior .NET/C# developer role at an established Financial Services Organisation, building and running product features across front and back end on a Microsoft/Azure stack. The role blends hands-on development with DevOps/SRE responsibilities: owning CI/CD pipelines (GitHub Actions, Octopus Deploy), infrastructure as code, observability, and incident response under a "you build it, you run it" model. Fully remote, requiring at least 3 years of experience; no salary or benefits were disclosed.

About the Role
Excellent opportunity opens to join an established Financial Services Organisation as their new Senior Developer. With a strong foundation in .NET and C#, you will be essential to the designing and building of features across the stack, as well as act as a visible figure within the firm engaging multiple stakeholders.
Responsibilities
•Design and build product features across the front and back end, engaging fully in the development lifecycle of applications and tools and contributing hands-on to all development tasks, from coding to reviewing and releasing to production
•Collaborate closely with team members, product owners, and stakeholders
•Design, build, deploy, and support software across front and backend stacks
•Build and maintain automated CI/CD pipelines and test automation to facilitate a seamless, repeatable route to production for Azure hosted solutions
•Operate and support environments up to and including production, instrumenting services with meaningful observability so releases can be trusted and issues responded to quickly
•Live the "you build it, you run it" model
•Implement and refine DevOps practices, building and owning CI/CD pipelines, managing infrastructure as code, and instrumenting services with observability (metrics, logs, and traces) so their health is visible
•Take part in operating live services, including release management, alerting, and incident response, while actively reducing toil, technical debt, and manual effort through automation
•Take ownership of personal learning paths, continually acquiring new skills, particularly across operations, SRE, and observability, to enhance team solutions and individual performance
Requirements
•You are a capable, hands-on software developer who enjoys designing and building product features across the front and back end
•The operations and SRE focus in this role is something you bring in addition to strong development skills, not instead of them, and you should be equally happy shipping product features as you are improving how we run them
•You have developed modern component-oriented front end applications using frameworks and libraries and have a good appreciation of UX (User eXperience)
•Solid working knowledge of C# and the .NET stack. Current tech stack is primarily Microsoft / Azure focused; C# is the primary language
•Advocate of key principles such as SOLID and CLEAN code, applying to all areas of development
•Keen to write code that is self-explanatory and easy to maintain
•Sound grasp of modern engineering principles and prefer working in small iterations that optimise feedback
•Like to validate hypotheses via experiments
•A genuine interest in operations and Site Reliability Engineering, caring about how services actually behave in production, not just whether they pass their tests
•Experience (or a strong desire to grow) building and maintaining CI/CD pipelines and automating the path to production. GitHub Actions and Octopus Deploy are used, but an understanding of the principles behind CI/CD is more important than the specific tooling used
•Have worked in an environment that deploys regularly to production
•Appreciation of observability, using metrics, logs, and traces (for example Azure Monitor / Application Insights, Datadog, Grafana/Prometheus, or OpenTelemetry) to understand system health, and an interest in SLIs/SLOs and alerting
•Comfort with, or enthusiasm to learn, Infrastructure as Code to provision and manage environments in a repeatable, reviewable way
•Willingness to take part in operational duties such as releases, incident response, and keeping live services healthy and reliable
•At least 36 months of experience required
Nice to Have
•Experience with Okta (or a comparable identity and access management platform, such as Microsoft Entra ID) for authentication and authorisation
•Hands-on experience with Terraform for Infrastructure as Code
