THE GIG
We are looking for top-notch data-driven back-end developers to work on a complex microservice-based distributed system in use 24/7. You'll design/develop C# RESTful Web APIs and microservices & improve unit, integration and acceptance testing (with the Testing team). Tech Stack

Unit Testing & mocking frameworks (nunit, Moq, NSubstitute/similar) SQL Server 2012/Postgres ORM (EF6, EF Core, NHibernate) CI/CD - Continuous Delivery (Git, Jira, Jenkins, Teamcity, Octopus). Bonus Points
Exposure to high-traffic / distributed software systems Docker, Kubernetes or similar .NET Core SOA design/maintenance AWS or Azure. Join the dream team. Oh and the employer?

You'll be representing a progressive, entrepreneurial R&D firm that provides a sophisticated portfolio of product development, early-stage investment & advisory services engaging with clients through co-innovation partnerships. They re well-liked in the market. They are considered the SAS in their domain. People love working there. We love working with them. You'll love working with them. People stay a long time. Expect to stay there for 2-3yrs + on contract. But maybe you re a job hopper. Maybe you d dislike the security this d give you. They re super niche. Boutique.

They have strategic partnerships, acquisitions and investments. You can learn a lot through collaboration with some brilliant minds. You'll be expected to produce magic, often. But you might not enjoy that kind of hustle. All-in-all, it s the kind of place where you can feel energised and not get bored. If you agree, the easiest and the best thing you could possibly do is hit the Apply button. The application/hiring process blends hi touch (speak with a human) & low touch (digital automation) to help fast track (accuracy/speed). We're aiming for a 1-2 week turnaround time.
