We are looking for a .NET Software Architect to work on a project in the Fintech Industry
Our teammates are talented people that come from a variety of backgrounds. We’re committed to building an inclusive culture based on trust and innovation.
You will be part of a distributed team developing new technologies to solve real business problems for a global private equity firm managing 60+ portfolio companies, on a major platform rebuild - modernizing a core banking/reconciliation platform from a tightly-coupled .NET monolith into an MVC architecture (ASP.NET Core, Razor Pages, Telerik), migrating several hundred business rules onto a test-driven validation layer, and integrating with 15–20 remote databases on Azure.
We are looking for a Principal-calibre engineer with strong, current C#/.NET expertise, real experience taking a legacy monolith through a modern re-architecture, and the stakeholder-management maturity to communicate confidently and proactively with a demanding client. Hands-on fluency with AI-augmented, agentic development workflows (e.g. Claude Code) is expected, not just tool familiarity.
Own end-to-end technical delivery - the ASP.NET Core/Razor Pages front end with Telerik components, and the underlying C#/MS SQL Server back end - within the core delivery team.
Lead the discovery, characterisation, testing and migration of business rules, currently split across stored procedures and application code, onto a reliable, test-driven validation layer as part of the platform rebuild.
Help define and drive the transition from a tightly-coupled monolith to a modern MVC architecture, including hardening the existing API layer toward a full REST implementation.
Design and build resilient integrations across 15–20 remote databases, working within the Azure App Configuration and Key Vault infrastructure.
Use Claude Code, GitHub Copilot and Zartis' Zcora instruction framework to structure and accelerate AI-assisted delivery with appropriate human review and validation.
Act as the primary technical point of contact for client stakeholders, bringing Principal-level communication, expectation-setting and delivery ownership.
Drive quality through to the shift-left QA effort (Playwright automation, SonarQube quality gates, Three Amigos sessions) to reduce regression cycles.
Strong, current C#/.NET expertise: Azure, ASP.NET Core/MVC, Razor Pages, Telerik UI components and MS SQL Server.
Proven experience with legacy-to-modern migrations and monolith-to-MVC architecture, ideally on tightly-coupled, full-stack codebases.
A track record of strong stakeholder management and clear, proactive communication in senior or principal engineering roles.
Hands-on fluency with AI-augmented, agentic engineering workflows (Claude Code, GitHub Copilot or similar) - able to speak concretely about your own approach, not just tool familiarity.
Comfort operating in a regulated financial-services or private-equity environment.
Azure cloud infrastructure experience, particularly App Configuration and Key Vault.
Exposure to shift-left QA practices - i.e. Playwright, SonarQube.
Experience with GitHub, including migrations away from Azure DevOps.
Prior experience in private equity, fund administration, or wider financial-services technology.
