Location: Auckland, New Zealand; on-site

Company

hirify.global develops connected animal-worn collar systems that help farmers manage cattle grazing more productively and sustainably.

What you will do

• Analyse collar performance across large fleets, including power consumption, battery life, GPS, sensor behaviour, and real-world operating conditions.
• Build a ground-truth understanding of how the devices are used on farms and identify differences between intended and actual usage.
• Process fleet telemetry, logs, and field data to distinguish genuine performance effects from data-quality artefacts.
• Apply first-principles reasoning to sensors, radios, batteries, firmware, and physical operating conditions.
• Inform new product designs and hardware revisions using evidence from field performance.
• Communicate findings across firmware, hardware, and product teams and follow improvements through implementation, validation, and production.

Requirements

• Background in engineering science, physics, or a similarly quantitative technical discipline, with experience applying it to physical-world problems.
• Strong data-analysis skills and experience working with large, noisy datasets in Python or a similar language.
• Ability to clean, filter, and validate data before drawing conclusions.
• Strong first-principles reasoning, curiosity, ownership, and follow-through.
• Strong communication skills for explaining technical findings to engineers across disciplines.
• Ability to work on-site in Auckland, New Zealand.

Nice to have

• Experience in statistics or applied mathematics.
• Experience working on optimisation problems.
• Curiosity about farming, animal welfare, or hardware operating outdoors and on live animals.

Culture & Benefits

• Mission-driven work focused on improving farming productivity, sustainability, and animal welfare.
• High-performance culture with autonomy, learning, and responsibility for meaningful technical problems.
