Staff Software Engineer

Now is an amazing time to join Nozomi Networks as we build the future of OT and IoT cybersecurity.

We defend some of the world’s largest organizations and critical infrastructure in more than 68 countries and we’re just getting started. Our AI-powered cybersecurity platform secures operational technology (OT) and Internet of Things (IoT) infrastructures for enterprises and government entities across energy, manufacturing, transportation, resources, and critical infrastructure.

We are looking for a Staff Software Engineer to join our engineering organization and play a key role in shaping the architecture, scalability, and long-term evolution of our platform.

As a Staff Engineer at Nozomi Networks, you will operate at both a technical leadership and hands-on engineering level, driving complex initiatives across teams while setting a high bar for engineering excellence. You will own critical areas of the system, influence architectural decisions, and mentor engineers, while delivering impactful features and platform improvements at scale.
The final job title (e.g., Software Engineer, Senior, or Staff) will be aligned to the successful candidate's demonstrated level of knowledge, skills, and impact, rather than years of experience.

You could be the next "Nozomier"! If this sounds like you, read on.

In this role you will:

• Lead the design and evolution of distributed systems that power our OT/IoT cybersecurity platform

• Drive architecture decisions with a long-term perspective on scalability, performance, and maintainability

• Own cross-team initiatives, aligning engineering efforts with product and business priorities

• Identify and systematically reduce technical debt, improving system reliability and developer productivity

• Act as a technical multiplier, mentoring engineers and raising the bar on design, code quality, and operational excellence

• Define and champion best practices in software design, testing, and observability

• Collaborate closely with Product, SRE, and Security teams to deliver end-to-end solutions

• Influence and improve engineering processes, ensuring effective delivery in a fast-paced agile environment

• Take ownership of mission-critical features and services, from concept through production and beyond

• Embody Nozomi Networks’ cultural pillars, promoting transparency, trust, and accountability

To be successful in this opportunity, you will have:

• Extensive experience designing and building large-scale distributed systems in production environments

• Strong expertise in at least one core language: Golang, C++, or Ruby

• Familiarity with JavaScript/TypeScript and React is a plus

• Proven track record of technical leadership beyond team boundaries

• Deep understanding of system design, algorithms, and data structures

• Experience with modern backend architectures, APIs, and service-oriented systems

• Solid background in automated testing strategies (TDD, BDD, integration testing)

• Strong knowledge of PostgreSQL and data modeling is a plus

• Understanding of networking fundamentals (TCP/IP , UDP , etc.) is highly valuable

• Experience working in Agile environments with cross-functional collaboration

• Ability to operate in high-trust, high-confidentiality environments

Nozomi Networks is the leader in OT and IoT Cybersecurity. We protect the world's critical infrastructure, industrial and government organizations from cyber threats by providing exceptional network visibility, threat detection and operational insight.
