At Halter, we’re on a mission to enable farmers and graziers to run the most productive and sustainable operations. Our customers are using Halter to break free from the time-intensive constraints of conventional practices. Imagine watching 500 cattle stand up and walk calmly towards their next break? No quad bikes, no dogs, no fences. Just a group of cattle walking at their own pace. People say it looks like magic. Our customers are revolutionizing grazing with Halter. It's changing lives and transforming an industry. People join Halter to do meaningful work. By joining us you’ll be solving challenging problems within a talented team and a culture built for high performance. Our team out-think, out-work and out-care. We’re committed to delivering real change in the world - this isn’t easy, and in truth, we love that it’s hard.
We’re backed to deliver on a mission that matters by Tier 1 investors including Founders Fund, Bessemer Venture Partners, BOND, DCVC, Blackbird, Promus Ventures, Rocket Lab’s Peter Beck and Icehouse ventures.

To ensure we can keep the system airtight and continue to deliver on this mission, we’re looking to bring on a Cloud Security Operations Engineer. Halter isn’t a “small SaaS app” - we support hundreds of thousands of devices operating out in the field, paired with a mobile + web product, and relied on daily by farmers. As we scale globally, security becomes less about checklists and more about building the right systems so we can move fast and stay secure.
This is a hands-on role focused on AWS infrastructure security and security operations. You’ll be responsible for improving preventative controls, deploying and operating security tooling across our cloud environment, and strengthening our detection and incident response capability. You’ll also help evaluate and roll out new security technologies (think SIEM/SOAR, better telemetry/log pipelines, higher-signal alerting, and automation) as our SecOps function matures.
You’ll collaborate closely with our Platform team, and partner with Application Security to build security foundations that engineers can actually use - the kind that make the secure path the easy path.
Secure and continuously improve our AWS environment across a mix of managed and self-managed services.
Deploy, configure, and operate security tooling on cloud infrastructure (including EC2 instances), improving hardening and visibility.
Write and maintain Terraform/IaC to roll out security controls and configuration changes safely and repeatably.
Investigate security events and incidents: assess severity and blast radius, drive mitigations, and embed learnings into prevention.
Improve incident response readiness: playbooks, alert quality, response workflows, and automations to reduce time-to-detect and time-to-contain.
Evaluate and roll out new security capabilities (e.g., SIEM/SOAR, EDR improvements, logging/telemetry), owning the journey from “is this fit for purpose?” to “this is running well in production.”
Build security “platform” foundations that teams can consume easily - enabling developers rather than throwing problems over the wall.
Participate in a security on-call rotation (details evolving, likely similar to Platform’s approach).
Deep experience with AWS and securing production cloud environments (strong understanding of AWS resource types and architecture).
Strong security operations / incident response experience, including investigation and triage, ideally with EDR and SIEM-style tooling.
Comfortable turning noisy signals into high-signal detections, and improving monitoring/detection over time.
Strong Infrastructure-as-Code mindset (Terraform ideal; must be able to confidently read and change Terraform safely).
Thrives in ambiguity and fast-changing environments - can find the highest-leverage problems and make progress without perfect runbooks.
Pragmatic approach to security: reduces risk meaningfully while preserving developer velocity and operational effectiveness.
Level-headed and accountable - doesn’t panic, owns outcomes, and learns quickly.
Comfortable working with AI as a tool (but thoughtful and critical, not hype-driven).
Motivated by Halter’s mission - you want your work to matter, even when it’s behind the scenes.
There’s a reason you visit your friends in person, live with your family and don’t do dinners over Zoom. Humans are wired for connection. We believe a world-class, in-person office culture is the best way for high-performing teams.
Being office first is a core pillar of our culture. We believe in-person connections are key to driving your own growth, learning, impact, and building genuine long-lasting relationships. Strong relationships make it easier to disagree, give feedback, and do meaningful and aligned work. We don’t like having heaps of rules or policies, but this means having strong, trusted relationships is critical.
We’re office first, not office only. This means working from the office everyday is our default setting, but we flex when we need to. We have a high-trust culture, so everyone is trusted to do what’s best for Halter.
Our office vibe is something special, it’s hard to describe until you’re here, but people at Halter who have come from fully remote or hybrid companies say they could never go back - the high energy and spectacular people they are now surrounded by everyday makes work so enjoyable. Your growth, your learning and your impact is truly unlimited here, and a big part of that comes from being together solving problems, innovating, building context, and constantly learning from each other.
Halter is committed to promoting a diverse and inclusive workplace — a place where we can each be ourselves and do the best work of our lives. Research shows that while men apply to jobs when they meet an average of 60% of the requirements, women and under-represented groups of candidates tend to only apply when they meet every requirement. If you think you have what it takes but don’t necessarily tick every requirement on this job description, please still get in touch and apply to Halter. We’d love to chat to see if you’ll be an epic fit!
If this opportunity sounds like you, please apply below by sending through your cover letter explaining why you’re excited about this role and working at Halter, along with your CV, and we’ll be in touch!
