Full description
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:
- Frontend: Angular / TypeScript, complex, performant web applications
- Real-time: SignalR-based live bidding and event-driven workflows
- 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
