Our platform empowers teams to find, fix, and prevent security risks in application code and infrastructure as code through automation and security-as-code principles. We're looking for a skilled Senior Backend Engineer to join our team and contribute to our Cortex Cloud platform.
As a Senior Backend Engineer, you'll have a high-impact role in shaping the future of our code security products. Beyond building robust and scalable backend features, you'll help drive performance, reliability, and innovation across our systems. Our group owns and leads the departments data pipelines, databases, and enrichment and persistence flows. If you're excited by technical challenges, meaningful ownership, and making life easier for developers - this is the place for you.

As a QA Manager , you will play a unique role that combines leadership with deep technical involvement. While leading and growing the QA organization, you will also be expected to develop a deep understanding of our products, architecture, and technical implementation details. This is a hands-on role where you will work closely with engineers, participate in technical discussions, investigate complex issues, and help shape testing strategies for highly technical features. Success in this role requires both strong people management skills and the ability to dive deep into the product and technology.

we practice a modern approach to quality where QA is not a gate to release but an added value to dev, and our goal to shift left our testing and provide fast feedback loop to dev.

As part of this role, you will:

Lead, mentor, and grow a team of QA engineers.
Develop deep expertise in products, architecture, and technical design.
Work closely with developers to understand complex features, review designs, and identify quality risks early in the development cycle.
Oversee test planning, execution, and release readiness across multiple teams.
Partner with Engineering and Product teams to ensure quality is embedded throughout the development lifecycle.
Drive improvements in testing methodologies, automation coverage, and quality metrics.
Build visibility into product quality through reporting, dashboards, and data-driven decision making.
Support hiring, onboarding, and career development within the QA organization.
Develop a deep understanding of enterprise customer environments and use cases to ensure effective testing strategies.

As an Engineering Manager at Cortex Cloud, you will lead a team of ~6 engineers operating in one of our most complex and cross-functional domains. This role requires a strong blend of people leadership and deep technical expertise, including systems design and large-scale distributed cloud architectures. You will be responsible for driving the design and delivery of complex, high-impact systems, while ensuring the team executes against the roadmap with both speed and engineering rigor.
Key Responsibilities
Build, mentor, and lead a high-performing software engineering team, fostering a culture of empowerment and driving both individual growth and collective impact.
Partner closely with Product Management and cross-functional teams (Infrastructure, Research, UX) to define priorities and shape multi-quarter product roadmaps, ensuring alignment across all stakeholders.
Own the end-to-end software development lifecycle, translating product strategy into executable plans and ensuring consistent, high-quality, on-time delivery.
Provide architectural leadership for scalable, distributed systems operating at petabyte scale, guiding the design and implementation of high-throughput, cloud-native backend microservices.
Drive production readiness by enforcing best practices around deployment, observability, reliability, and runtime stability, focusing on the details to ensure operational excellence.
Align stakeholders across business units through clear communication of technical strategy, trade-offs, priorities, risks, and execution plans.
Engage directly with strategic customers to lead technical deep dives and architecture reviews, and to influence future product direction.
Foster a culture of high engineering standards, accountability, and continuous improvement, with a strong emphasis on quality and security.

As a Network QA engineer, you'll own the quality of Enterprise Network products: ZTNA, SWG, SASE, and VPN. You'll build the test frameworks that verify how traffic is routed, inspected, secured, and delivered across real enterprise environments, then use them to catch problems before customers ever see them. You'll also become a deep source of product and protocol knowledge, working shoulder to shoulder with our R&D team.

As part of this role, you will:

Design, build, and maintain automated test suites for our network stack, covering ZTNA policy enforcement, SWG traffic inspection, SASE routing, and VPN tunneling, at both the end-to-end and component level.
Grow our network test automation infrastructure, adding coverage for new features and hardening existing suites as the product evolves.
Build and manage test environments that reproduce real customer topologies, including varied network conditions, identity providers, operating systems, and browsers.
Validate performance, reliability, and security behavior under load, latency, and failure scenarios that mirror how enterprises actually run.
Plan and execute manual testing for new releases where automation doesn't yet reach, and convert repeatable manual cases into automated ones.

we are building an agentic development lifecycle, an infrastructure of autonomous agents that work alongside our engineers to accelerate and improve how we build software. Our goal is to ship faster, with higher quality, and to continuously tighten the feedback loop between what the agents produce and what engineering actually needs. Over time, this system should compound: every improvement makes the next one easier to reach.
we are an enterprise secure browser used by some of the largest organizations in the world. It's a complex, multidisciplinary product spanning browser core, frontend, extensions, and backend services, and it runs at scale for customers who need it to always work. The bar for what we ship is high. That means whatever agentic infrastructure we build has to meet the same standard. We're not here to vibe code our way to production.
We're looking for an AI Engineer with a product builder's mindset. You have real experience with AI and agentic workflows, and you know how to take a complex project from idea to adoption, technically and organizationally. That means working across teams, aligning with security, infrastructure, and other engineering groups, and understanding that building the system is only half the job. Getting people to trust it is the other half.
We aren't looking for a conventional senior developer; we need someone whose mindset is adapted to technical challenges that didn't even exist 18 months ago.
