We’re Hiring: Senior Full-Stack Engineer – Portals & Identity
📍 [Location / Remote / Hybrid] | 💼 5+ Years | 🏦 Financial Services
Are you the engineer who gets excited about
OAuth flows as much as
beautiful React UIs? We’re looking for a hands-on technical owner for our customer and intermediary portals.
🔐 Your first mission
Lead the migration of our IdentityServer-based login platform to a modern identity solution (Entra External ID / Duende / OpenIddict). You’ll help choose the platform, design secure login flows (OIDC, PKCE, MFA, passwordless, federation), and deliver it with zero loss of functionality.
🛠 Beyond that, you’ll
✅ Own the portals end to end: features, performance, security, and incidents
✅ Guide developers (including external vendors) and review PRs
✅ Safeguard our architecture: DDD/CQRS, BFF, event-driven design
✅ Partner with the business to prioritise what matters
💡 What You Bring
🔹 Next.js, React, and TypeScript (App Router, SSR) with Tailwind
🔹 Strong OIDC/OAuth2/SAML knowledge, and you’ve
led at least one IdP migration
🔹 .NET/C# and ASP.NET Core, with CQRS, MediatR, and Azure Service Bus
🔹 Azure (App Service, Key Vault, APIM), Terraform, and GitHub Actions
🔹 Experience leading a small team or vendor
🔹 A security-first mindset (OWASP, GDPR, regulated environments)
⭐ Bonus points for
Mortgage or fintech experience, Contentful, Playwright, SonarCloud/CodeQL, monorepos
🙌 You’re Someone Who
Takes ownership, prefers maintainable over clever, and communicates clearly with both techies and business teams.
