Staff Engineer QA- Versa messaging Services

Location: Varthur, India

About Us:
Versa Networks, Inc. is a vendor of a unified Secure Access Service Edge (SASE) platform. Versa's goal is to provide unprecedented business advantages through a software-based approach that allows for unmatched agility, cost savings and flexibility. We have created a platform that is feature-rich, scalable and easy to use for both enterprise and service provider use cases.

Job Summary:
VMS is a core component of Versa's SASE security platform. It collects user identity, authentication, device posture, IoT, UEBA and threat intelligence data and distributes it, per tenant, to Versa enforcement points for Zero Trust, identity-based firewall, micro-segmentation and SSE policies. Data sources include SCIM, passive and active authentication, RADIUS and threat intelligence feeds. We are looking for a Staff QA Engineer to lead the testing of VMS, covering functional correctness, tenant isolation, high availability, upgrades and performance.

Educational Qualification:
B.E./B.Tech. or higher degree in Computer Science, Information Technology, Electronics and Communication or equivalent.

Professional Qualification:
8–12 years of experience in software quality engineering and test automation, including at least 3 years testing networking, security or distributed systems products.

Job Responsibilities:
Quality strategy

• Define the test strategy, test plans and release-readiness criteria for VMS.

• Provide the quality status for each release, with test results and defect data.

• Mentor SDETs and review their test designs and automation code.

• Work with developers to add unit and contract tests to every change, and add quality gates to the CI/CD pipeline.

Functional and security testing

• Test that identity, posture and threat intelligence records are delivered correctly to enforcement points, including adds, updates, deletes and revocations.

• Measure how long it takes for a change, such as a user logout or a new threat feed entry, to take effect.

• Test tenant isolation, so that data for one tenant is never sent to or changed by another.

• Test behavior when a data source or downstream consumer is unavailable, including data aging and recovery.

Test automation

• Build integration and end-to-end test frameworks for the publish/subscribe path across record types, services and tenants.

• Build contract and schema-evolution tests for the gRPC/Protobuf interface to keep backward compatibility with deployed clients.

• Build simulators for upstream data sources (SCIM, RADIUS, authentication events, threat feeds and posture data) to test at scale.

Platform, high availability and performance

• Maintain the installation and upgrade test matrix: ISO and package installs, single-node and HA setups, FIPS and non-FIPS builds, upgrade, rollback and data migration.

• Test active/backup failover and data replication, including random failures and reboots, and measure RTO and RPO.

• Run performance, capacity, soak and memory-growth tests, and document the supported limits for throughput, record count and tenants.

Essential Skills:

• Test automation development in Go or Java, and Python or another scripting language.

• Experience testing distributed or stateful systems, such as messaging, streaming, data stores (for example Redis or Kafka) and HA failover.

• API and contract testing, preferably with gRPC/Protobuf.

• Good knowledge of TCP/IP, HTTP, TLS/mTLS and PKI basics.

• Strong Linux and shell scripting skills.

• Experience testing on-premises or appliance software, including installation and upgrade.

• Working knowledge of Docker and Kubernetes.

• Performance and soak testing, including load generation and profiling.

• Experience with CI/CD pipelines and automated quality gates (for example Jenkins).

Desirable Skills:

• Experience with SASE, SSE, ZTNA, NGFW, SD-WAN or micro-segmentation products.

• Knowledge of identity protocols such as SCIM, SAML, OAuth2/OIDC, RADIUS and LDAP.

• Experience with threat intelligence feeds, UEBA, endpoint posture, IoT device identification or security group tags.

• Experience with syslog and log analytics pipelines.

• Exposure to security certification testing (FIPS 140-3, STIG, Common Criteria).

• Deeper Kubernetes experience (cluster setup, networking, storage, operators).

Experience with Prometheus and Grafana, and with public cloud platforms
