Sr Engineer - BizApps

8x8 connects our customers and teams globally, empowering CX leaders with performance and insights to make smarter decisions, delight customers, and drive lasting business impact. We're looking for a Senior Engineer who leads with strong programming fundamentals and uses AI to move fast across any technology. You'll own the full delivery stack — from API design and business logic through to modern frontend experiences — building systems that customers and partners interact with every day. Salesforce is one important tool in your kit, not your entire identity. You think in systems, you own outcomes end-to-end, and you bring the same engineering rigor to a React MFE as you do to a backend integration layer. The bar here isn't knowing every technology on day one — it's having the fundamentals and AI fluency to close any gap fast, and the judgment to know when building isn't even the right answer. What You'll Do Engineering for scale — customer & partner systems Design and deliver world-class experiences for customers and partners — quote-to-cash flows, self-service portals, order management UIs — systems that are reliable, fast, and built to scale Own delivery end-to-end: API design, business logic, integration layer, and UI — you don't hand off, you ship Think in outcomes: a partner portal that converts, an order flow that needs zero manual intervention, a customer journey that doesn't break Frontend — React, Angular, MFE Build production-grade UIs in React or Angular — real apps that ship and scale, not prototypes Design and implement Micro Frontend (MFE) architectures using module federation — independently deployable micro-apps that compose cleanly across platforms Build and maintain shared component libraries and design systems that span multiple frontend surfaces Develop Lightning Web Components (LWC) within Salesforce when the platform is the right home for the UI Backend & integrations — including Salesforce Build and extend backend services in Java, Python, Node, or whatever the problem calls for — you pick the right tool, not the familiar one Design REST/SOAP API integrations across Salesforce, billing platforms, ERP, portals, and data warehouses — own the data flow end-to-end Apply Salesforce platform knowledge (Apex, OmniStudio, CPQ) to own the business logic layer where Salesforce is the system of record • Debug integration failures across the full stack — frontend calls, middleware, Salesforce callouts, and downstream service logs Work smart with AI Use Claude (Anthropic) for architectural reasoning, code review, documentation, and solving hard problems faster than you could alone Use Cursor AI for day-to-day development — completions, refactoring, navigating large codebases We expect you to be measurably faster because of AI — not just familiar with the tools Bring a point of view: what should still be built, what should be automated, what should be rethought entirely? Collaborate and elevate Translate messy business requirements into clean, scalable technical solutions — partner with BAs, architects, and stakeholders Conduct code reviews and mentor peer developers — raise the bar just by being in the room Document what you build so the next engineer isn't starting from zero Ship with quality Own unit, integration, and regression testing across frontend, backend, and Salesforce surfaces Support CI/CD deployments using Git, Copado, Jenkins, or equivalent tooling Triage and resolve post-deployment issues without waiting to be asked What We're Looking For Must-haves 5+ years of software engineering with strong fundamentals — OOP, data modeling, APIs, debugging, system design Production frontend experience in React or Angular — real apps that shipped and scaled Experience with Micro Frontend (MFE) architectures — module federation, independently deployable components, or equivalent Ability to build, read, debug, and extend backend services in Java, Python, Node, or equivalent Experience building and maintaining system integrations via REST/SOAP APIs Solid Salesforce exposure — enough to own Apex, LWC, and platform configuration without hand-holding Measurably faster and better because of AI — daily use of Claude and Cursor AI, not occasional experiments Comfortable with Git, CI/CD pipelines, and Agile delivery in Jira Nice to have You've context-switched between a React MFE, an Apex service layer, and a Java integration in the same sprint without losing stride Hands-on experience with Vlocity/OmniStudio or Apttus/Conga CPQ You've built AI-assisted workflows, Claude-powered tools, or MCP integrations on enterprise systems Salesforce certifications: Platform Developer I/II, OmniStudio Developer Familiarity with telecom, CPQ, billing, or order management domains You ask 'why are we building this?' before 'how do we build this?'
