About JazzX AI

Vision:

Enterprises operating on institutional intelligence—governed, self-improving, and scalable beyond individual expertise.

JazzX AI is defining the future of enterprise work—by building AI-native digital workers that actually get the job done.

We believe enterprises don't scale expertise—they lose it. Knowledge stays trapped in individuals, judgment gets applied inconsistently, and the best talent spends time on work that should run itself. We're changing that.

JazzX AI transforms messy enterprise reality into institutional intelligence: governed digital workers that capture expert judgment, make every decision explainable, and continuously improve through real-world execution. The result is faster decisions, higher-quality outcomes, and reliable execution at scale—in domains where getting it wrong isn't an option.

We're starting with lending and due-diligence workflows—complex, regulated, high-stakes. From here, we're building the backbone for enterprise intelligence across industries.

This is early-stage, hard, and consequential work. If you want to be part of bringing AI systems to market that actually run in production, handle real complexity, and deliver real outcomes—not demos, not chatbots—JazzX AI is the place.

About SAIGroup

SAIGroup a private investment firm that has committed $1B to build and scale next-generation, AI-powered enterprise software companies. SAIGroup’s portfolio serves 2,000+ global enterprise customers, generates nearly $800M in annual revenue, and employs 4,000+ people worldwide — providing JazzX AI with long-term capital, deep operating expertise, and access to real-world enterprise scale from day one.

The Role

As a Senior Full Stack AI Engineer at JazzX AI, you will play a pivotal role in designing, building, and enhancing innovative, high-performance AI-driven solutions. You'll work closely with cross-functional teams — AI/research engineers, software engineers, architects, product managers, and designers — to translate complex platform and product requirements into elegant, scalable, and modular AI,software, and infrastructure components.

You'll independently build end-to-end applications — from pixel-perfect frontend to robust backend services and AI agent integrations. You thrive in a fast-moving environment where you leverage AI tools (Cursor, Claude Code, Copilot) and vibe coding to rapidly prototype, build, and ship production-grade features. You don’t just use AI — you build with it and build on top of it.

Senior Full Stack AI Engineer

• Drive architecture decisions for new features and services end to end
• Lead the design and development of high-performance, scalable services using a cloud-first approach
• Build and ship complex, multi-service features with minimal oversight
• Mentor engineers and foster their growth and development, elevating team velocity through tooling and best practices
• Design scalable patterns for AI agent orchestration, data pipelines, and micro-frontends
• Champion DevOps and AIOps best practices for AI services, including robust monitoring and alerting strategies, observability, privacy, and security
• Lead technical planning and shape the team's AI-native development culture
• Typically 5–8+ years of relevant experience with demonstrated technical leadership
