Staff Software Engineer

We are looking for a Staff Backend Software Engineer to lead the technical strategy, architecture, and implementation of our large-scale AI chat agent platform. This system is designed to support 20+ million users globally, making it one of the most ambitious backend initiatives at Nexthink.

As a Staff Engineer, you will go beyond implementation: you will set technical direction, influence cross-team design decisions, and serve as a trusted advisor to both engineering leadership and product. You’ll tackle problems of scale, reliability, and performance while partnering with AI/ML, Infra, and Security teams to build production-ready AI experiences.

This is a high-impact, high-ownership role where you’ll be entrusted to make foundational architectural decisions and mentor senior engineers, ensuring Nexthink’s AI systems are built to scale with the future.

• Define and drive technical vision and architectural strategy for the AI chat backend platform.

• Lead design of highly scalable, low-latency, distributed systems supporting 20M+ global users.

• Partner with product, infra, and AI/ML teams to align engineering strategy with business objectives.

• Provide technical leadership across multiple teams, influencing design patterns, coding standards, and best practices.

• Architect and deliver fault-tolerant APIs and services capable of handling large-scale real-time workloads.

• Champion observability, performance, and resiliency across the stack.

• Act as a mentor and multiplier, raising the technical bar and helping senior engineers grow.

• Lead technical deep dives, design reviews, and roadmap alignment discussions with leadership.

• Ensure security, compliance, and cost-efficiency are embedded in design from day one.
