Senior Node.js Developer (UK)

Remote Full-time Hiring now

Who We Are

Flosum is a bootstrapped, profitable B2B SaaS company building the leading Salesforce-native DevSecOps, Data Protection, and Security platform. Our solutions are trusted by Fortune 500 enterprises in the most heavily regulated industries on the planet — financial services, healthcare, government, and insurance.

We’re not a startup burning cash and chasing vanity metrics. We’re a proven, scaling business that reached profitability on our own terms. As a Salesforce Summit Partner and Innovation Award winner, we’ve earned our seat at the table alongside the biggest names in enterprise software.

Built 100% on the Salesforce platform. Serving enterprises that demand zero compromise on security, compliance, and reliability.

Why This Role Exists

We are entering an aggressive growth phase — expanding our product surface, deepening our platform capabilities, and accelerating our delivery velocity. We need senior-caliber Node.js developers who can own significant parts of our architecture and ship production code that enterprise customers depend on daily.

This is not a staff augmentation seat. You will work directly with engineering leadership, product managers, and the CEO. Your decisions will have real consequences, your opinions will be heard, and your craftsmanship will be visible to the customers who rely on our platform.

What You’ll Build

  • High-performance backend services and APIs powering enterprise-grade SaaS applications
  • Scalable, secure Node.js micro services and integrations within the Salesforce ecosystem
  • Modern front-end experiences using Vue.js and TypeScript that serve demanding enterprise users
  • CI/CD pipeline tooling, automation frameworks, and developer productivity infrastructure
  • Real-time data processing and event-driven architectures handling sensitive enterprise data at scale
