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 heavily regulated industries such as financial services, healthcare, government, and insurance. We’re a proven, scaling business that reached profitability on our own terms.
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. 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 microservices 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
Non-Negotiable Technical Requirements
- 5+ years of professional Node.js development in production environments
- Expert-level understanding of asynchronous programming, event loops, streams, and the Node.js runtime
- Deep experience with TypeScript in production codebases
- Strong command of RESTful API design, authentication patterns (OAuth 2.0, JWT), and API security best practices for enterprise environments
- Proven experience with SQL and NoSQL databases, query optimization, data modeling, and understanding the performance implications of schema decisions at scale
- Proficiency with Git workflows, code review practices, automated testing (unit, integration, and end-to-end), and CI/CD pipelines
- Solid understanding of containerization (Docker), cloud services (AWS/GCP/Azure), and infrastructure-as-code principles
Highly Preferred (These Will Set You Apart)
- Salesforce development experience: Apex, Lightning Web Components (LWC), Visualforce, or Salesforce API integrations
- Experience building or contributing to Salesforce ISV (AppExchange) products
- Vue.js front-end development experience, particularly with Vue 3 Composition API and state management
- Experience working in B2B SaaS companies serving enterprise customers with strict compliance requirements (SOC 2, HIPAA, FedRAMP, GDPR)
- Familiarity with DevOps/DevSecOps toolchains and practices in the Salesforce ecosystem
The Kind of Person We’re Looking For
- Missionary, Not Mercenary: You care about what you’re building and why. You take ownership not because someone assigned it to you, but because that’s who you are.
- Builder, Not a Bystander: You don’t wait for perfect specifications. You dig in, ask hard questions, propose solutions, and ship.
- Craftsperson Under Pressure: You write code that doesn’t just work — it survives. You understand that in regulated industries, your code is your reputation.
- Direct Communicator: You say what you think, respectfully and clearly. We value candor over politeness-at-the-expense-of-quality.
This Is a Long-Term Commitment
We are not looking for contractors who jump between projects every few months. We are building a world-class engineering team, and we invest heavily in the people who join us. In return, we expect commitment. This role is designed as a long-term, full-time engagement. You will grow with us. You will own systems end-to-end. You will see the direct impact of your work in how Fortune 500 companies build, protect, and deploy on Salesforce.
What We Offer
- Competitive compensation commensurate with your experience and impact
- Direct collaboration with the founding team and engineering leadership
- A profitable, stable company with aggressive growth plans
- The opportunity to work on enterprise-grade products used by some of the largest organizations in the world
- Meaningful technical challenges: security, compliance, scale, and reliability at the intersection of Node.js and Salesforce
