Lead Cyber Security Engineer
Halter
Date: 23 hours ago
City: Auckland, Auckland
Contract type: Full time

About The Role
Halter enables farmers to grow and graze more grass through the use of virtual fencing. Every farm is deployed with communication infrastructure and a collar for each animal, which is then paired with a mobile and web application. The result is tens of hours of labour saving per week, improved animal welfare, and increased productivity and sustainability of the land.
To ensure we can keep the system airtight and continue to deliver on this mission we are looking to bring on our first cyber security engineer.
With Halter's system now serving hundreds of thousands of devices in the field, and spanning over 30 engineers across five teams, we need to make sure we have the right ways of working in place to deliver a reliable and secure product as we expand globally.
As the first in this role you have the opportunity to define how we think about cyber security here at Halter. You will have ownership over everything from security practices, to education of the team, to threat detection, compliance, third-party assessment, penetration testing, and everything in between.
In this role you will be hands-on, operating with deep technical expertise, a high level of agency, as well as strong communication skills. You will work across the entire technical stack, from the mobile code, to our backend systems, all the way to the firmware running on the collar. You can expect a high level of collaboration working as part of our ‘context over control’ culture to introduce best practices that mature our security posture while ensuring we maintain the speed of delivery we value as a company.
As part of this you will work primarily in the AWS ecosystem across a mix of managed and self managed services. You will work alongside a small but deeply experienced platform engineering team, all with a strong mindset of IaC, a love for autonomy, and a passion for their craft.
What Your Day Could Look Like

Healthy body, healthy mind. We’re partnered with Southern Cross Health Insurance to support your well-being.
We offer 6 months of fully paid parental leave for primary caregivers, 4 weeks of fully paid secondary caregiver leave and many other parental benefits that support you and your family.
Our personal growth is important. Halter offers an annual $1000 self-development budget to be used for anything that fuels personal growth.
Our time to recharge is valued, we’re offered wellness leave and unlimited paid annual leave.
We offer an inclusive and attractive remuneration package made up of salary, benefits and an employee stock ownership plan.
Delicious snacks and drinks are available for your daily flow.
Our Office First Approach
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.
