Role
Who you are
- Currently enrolled in a full time Bachelor’s or Master’s degree program in Computer Science, Software Engineering, or a related field with an expected graduation date in Winter 2026/Spring 2027
- A positive, can-do attitude with strong ownership and drive to build world-class cloud segmentation software
- Strong programming skills in Golang or similar language with solid understanding of distributed systems, data structures, and concurrency
- Familiarity with Kubernetes, gRPC, Postgres, graph databases, caching databases and public cloud platforms
- Interest in cloud security, firewall orchestration, and Zero Trust segmentation
- Understanding of networking concepts such as VPCs, routing, and firewall rule evaluation is a plus
- A mindset focused on scalability, fault tolerance, and performance optimization
- Strong collaboration, problem-solving, and communication skills
What the job involves
- This is a 12 week internship program beginning on May 26th 2026 or June 22nd 2026
- Illumio’s Cloud Segmentation and Security Analytics team builds and operates the enforcement and analytics platform that stops lateral movement across multi-cloud and hybrid environments
- We transform massive volumes of customer inventory, topology, and traffic data from AWS, Azure, GCP, and OCI into actionable segmentation insights and precise policy enforcement
- Our systems leverage native cloud security controls to achieve Zero Trust segmentation at scale
- The team’s mission is to deliver real-time security analytics and enforcement orchestration that’s resilient, low-latency, and cloud-aware
- We address the toughest challenges around scalability, rate limits, resiliency, and consistency across diverse cloud environments using a modern, distributed tech stack
- Design and build distributed services that analyze traffic and enforce segmentation policies across multi-cloud environments
- Develop scalable orchestration layers to translate and apply policies using native cloud firewalls and controls
- Build data pipelines that correlate cloud resources, traffic, topology, and network telemetry to derive real-time insights into trust boundaries and policy effectiveness
- Contribute to algorithms that contain lateral movement, policy drift, and misconfigurations
- Optimize resiliency, latency, and throughput of enforcement workflows within cloud rate limit and API constraints
- Collaborate with cross-functional teams to deliver secure, observable, and performant microservices
- Participate in design discussions, performance reviews, and production readiness assessments to ensure high reliability
- What You'll Gain:
- Hands-on experience designing and deploying multi-cloud security and segmentation systems that operate at a massive scale
- Deep exposure to native cloud firewalls, enforcement points and policy APIs across AWS, Azure, GCP, and OCI
- Understanding of how to operationalize Zero Trust principles using distributed enforcement models
- Mentorship from senior engineers building industry-leading cloud microsegmentation technology
- Opportunity to design and demo a capstone project with measurable impact on scalability, resiliency, or security posture
Our take
Cybersecurity remains an ongoing battle, with evolving cyberthreats and ever-more determined cybercriminals, and major data breaches such as the SolarWinds hack have the potential to cause widespread disruption. Illumio is taking a different approach to most of the mainstream security companies, with a process called "microsegmentation". This makes it easier to guard companies from security breaches, and contain any breaches that occur.
Detection of viruses is no longer considered sufficient to keep companies and individuals safe. Illumio takes a “zero trust” approach, in which everything is viewed as suspicious, a similar approach to that which is used by the White House. The company operates at the cutting edge of microsegmentation, focusing on protecting cloud datacenters and workloads. With more and more companies moving to the cloud, this approach is crucial.
Illumio also protects endpoints, partnering with big players such as Citrix, Amazon Web Services, and Splunk. A collaboration with Appgate, a Zero Trust secure access company, delivers the industry's first integrated Zero Trust Network Access and Segmentation solution, which can reduce risk across hybrid infrastructure, and proves Illumio's dedication to innovating the space. Additionally, the company announced a Federal Risk and Authorization Management Program (FedRAMP), that is tailored to assist federal agencies in reducing risk.
