Principal / Lead Software Engineer – Platform Infrastructure (Go)

Our client is building a cutting-edge cybersecurity platform that helps enterprises protect their most critical systems through AI-powered intelligence, automation, and modern cloud infrastructure.

The platform operates at significant scale, processing complex security data through highly reliable distributed systems built for speed, accuracy, and resilience. The engineering team tackles some of the hardest challenges in modern security infrastructure, from real-time data processing and scalable backend architecture to building systems that perform reliably in mission-critical environments.

This is an opportunity to help shape the foundation of a next-generation security platform, building technology that directly impacts how organizations protect themselves in an increasingly complex threat landscape.

The Role

We are looking for a Principal / Lead Software Engineer to own the design and development of a new platform segment within the company’s core infrastructure.

We are looking for a strong systems engineering/ architecture mindset, someone who enjoys solving complex engineering problems, designing reliable distributed systems, and making architectural decisions that shape the future of the platform.

You’ll build backend systems that process real-time security data at scale, with a focus on performance, reliability, resilience, and long-term maintainability.

The primary language is Go (Golang) within a cloud-native environment built on Kubernetes and cloud infrastructure. While Go experience is preferred, the team values strong engineering fundamentals and systems thinking; experienced engineers can leverage AI-assisted development tools to become productive in Go quickly.

Responsibilities

• Own the architecture and development of core platform infrastructure components.
• Design and build scalable distributed systems and backend services.
• Make technical decisions around system design, performance, reliability, and scalability.
• Define service boundaries, data flows, and interactions across platform components.
• Build reliable systems with strong focus on testing, observability, and production readiness.
• Participate throughout the full development lifecycle, from architecture and implementation to deployment and production operations.
• Improve platform capabilities, automation, and engineering efficiency.
• Collaborate with engineers across teams and provide technical leadership and mentorship when needed.

Requirements

• Strong experience designing and building production-grade software systems.
• Strong distributed systems and backend engineering experience.
• A systems engineering mindset with the ability to reason about scalability, reliability, and complex technical trade-offs.
• Experience building cloud-native applications and working with modern infrastructure.
• Experience with Go (Golang) or the ability to become highly productive in Go quickly.
• Familiarity with Kubernetes, Docker, CI/CD, and cloud infrastructure environments.
• Experience with observability, monitoring, and operating production systems.
• Strong understanding of software quality practices, automated testing, and reliability engineering.
• Experience contributing to architecture decisions and driving technical direction.
• Ability to work independently and take ownership of complex technical initiatives.

Technology Environment

• Primary language: Go (Golang)
• Infrastructure: Kubernetes, Docker, Cloud platforms
• Architecture: Distributed systems, backend services, real-time data processing
• Engineering practices: CI/CD, automated testing, observability, AI-assisted development workflows

What’s Offered

• Opportunity to join a high-growth cybersecurity company building next-generation security technology.
• High level of technical ownership and autonomy.
• Ability to shape a core platform area from the ground up.
• Work on challenging distributed systems and infrastructure problems at scale.
• Collaboration with a global, high-performing engineering team.
• Competitive compensation package, including: medical and life insurance, 401(k) contribution plan, pre-IPO equity options, paid time of and additional employee benefits and perks
