Full Stack Engineer

Senior Full-Stack Engineer (.NET / Angular / Azure) | Remote | ZAR$90k-105k pcm
We're working exclusively with an internationally established B2B SaaS business to find a Senior Full-Stack Engineer who has been here before, someone who has built and owned complex platform features end to end, not just contributed to them.
The Platform
A mature, mission-critical SaaS platform mid-way through a significant cloud-native rebuild. Real customers, real revenue, real engineering standards. The platform powers high-value, high-volume transactional operations globally, live, real-time environments where reliability is the product. £50m+ transacted in 2025 alone, across multiple sectors and international markets.
The Role
You'll work closely with the Lead Software Engineer and product leadership, taking genuine ownership across:
Backend: .NET 10 / ASP.NET Core, APIs, services, distributed systems
Frontend: Angular / TypeScript, complex, performant web applications
Real-time: SignalR-based live bidding and event-driven workflows
Infrastructure: Azure-native (AKS, Service Bus, Container Apps, Key Vault, Monitor, Blob Storage)
DevOps: Docker, Kubernetes, CI/CD pipelines; you deploy what you build
Architecture: multi-tenant white-label SaaS, scalability, resilience, observability
Leadership: engineering standards, mentoring, technical direction
This is not a role for someone who needs architecture handed to them. You'll contribute to those decisions.
What You'll Need
7+ years of commercial software engineering experience
Deep, production-grade .NET / ASP.NET Core, this is not a "some backend experience" role
Strong Angular / TypeScript; complex Single-Page Applications, not just templates
Proven experience with Azure cloud-native architecture in production
Docker and Kubernetes in real environments, not just familiarity
PostgreSQL or equivalent at scale
Experience in high-availability, mission-critical or real-time systems is a strong advantage
Comfortable with full end-to-end ownership, design, build, deploy, support
Why This Role
Fully remote, flexible working, built on trust and accountability
Small, senior, highly collaborative team
Genuine technical influence, your decisions shape the platform
Up to £55,000 + 28 days holiday (inclusive of UK bank holidays) per year
If you are a senior engineer who has genuinely owned complex systems and wants to do serious work on a platform that matters, apply now.
