Trend Micro, a global cybersecurity leader, helps make the world safe for exchanging digital information across enterprises, governments, and consumers.

Fueled by decades of security expertise, global threat research, and continuous innovation, Trend harnesses AI to protect organizations and individuals across clouds, networks, devices, and endpoints.

The Trend Vision OneTM enterprise cybersecurity platform accelerates proactive security outcomes by predicting and preventing threats across the entire digital estate and environments like AWS, Google, Microsoft, and NVIDIA.Proactive security starts here.

* Location:

** This is a hybrid role based out of our Austin, TX office and requires in-office presence three days a week (Tuesday, Wednesday, Thursday).
*
* Position Summary:

** TrendAI is seeking a Senior Staff Software Engineer to help build
** Trend Vision OneTM Private Access**, our Zero Trust Network Access (ZTNA) capability. Private Access lets enterprise customers reach internal applications — RDP, SSH, web — without exposing those apps to the public internet and without a traditional VPN.The Austin team works across three pieces of Private Access: a
** Connector
* * on-premises next to the customer's application; a
** Relay
* * in our cloud that brokers the connection between the end user's device and the Connector; and a
** Controller
* * of cloud microservices that runs the policy, identity, and authorization plane. The product runs across many global cloud regions to meet customer compliance and latency needs. This is a hands-on engineering role with architectural scope.
** How We Build:
** We're moving in the same direction as the rest of the industry: engineers no longer just write code; we design the systems that produce it. Concretely, we're building toward a daily loop where:
* Engineers work through an agent harness (Claude Code, plus its peers) layered on top of Git Hub Actions, Jira, CI/CD, docs, and runtime data.
* Agents handle most of the inner development loop. Humans gate at the edges — architecture, end-to-end validation, the failures the agents can't resolve, and the question of what "good" actually means.
* Engineers design the pipeline; if the output is bad, we fix the assembly line.

We're partway through this transition and the candidate we hire will help define how much further it goes.
** AI makes mistakes — confidently.
** A senior engineer's value shifts from typing code (AI does that) toward defining the right requirements, catching the plausible-but-wrong output, and bringing the context AI doesn't have. The skills that matter most:
* ** Systems thinking** — catch failure modes (latency, cost, drift, silent failures) before they reach production.
* ** Operational instinct** — when something looks off in production, reach for metrics, profiling, and autoscaling without waiting for an SRE.
* ** Critical review** — design validation layers and catch the subtle thing that looks right but isn't.
* ** Security thinking** — zero-trust is the product
* and* the development model; reason about access control, data protection, and safe execution boundaries by default.
* ** Domain expertise** — understand (or be ready to learn) our customers' environments, the problems they bring us, and the operational realities that aren't in any spec.
** Responsibilities:
*** Design and implement features across the Connector, the Relay, and the Controller services that drive them.
* Own one or more Controller microservices end to end (rule engine, geolocation, event workers, proxy paths, connector management).
* Diagnose and resolve performance issues in production:…
