Location: Auckland, New Zealand; on-site with office-first daily attendance as the default

Company

hirify.global develops connected livestock collars and software that help farmers run more productive and sustainable grazing operations.

What you will do

• Design, implement, test, deploy, and support embedded C/C++ firmware for resource-constrained livestock collars running FreeRTOS.
• Build and maintain communication systems using LoRa mesh networking, cellular connectivity, BLE, CoAP, OSCORE, and protobuf.
• Develop signal-processing, timing, synchronization, filtering, and estimation algorithms for sensor and distributed-device systems.
• Debug intermittent field issues using logs, telemetry, and system-level root-cause analysis.
• Collaborate with hardware engineers on sensors, radios, power circuitry, and analog and digital interfaces.
• Improve platform quality, tooling, reliability, and engineering practices while mentoring other engineers through design reviews and code reviews.

Requirements

• Professional experience designing and delivering firmware for resource-constrained embedded devices.
• Strong C/C++ fundamentals and experience with interrupts, memory constraints, real-time behavior, and concurrency.
• Background in mathematics, physics, or equivalent practical depth, with the ability to reason about timing, signal behavior, probability, or control systems.
• Experience with wireless or networked communication systems such as LoRa, BLE, cellular, or mesh networking.
• Strong ownership, root-cause debugging skills, and comfort solving complex low-level hardware problems.
• Ability to collaborate effectively and give and receive feedback.

Nice to have

• Experience with RTOS internals, scheduling, priorities, and timing guarantees.
• Experience with GPS/GNSS, time synchronization, or distributed systems requiring tight coordination across nodes.
• Background in signal processing, control theory, estimation, filtering, or applied statistics.
• Experience with LTE-M, NB-IoT, eSIM, or similar low-power IoT technologies.
• Curiosity about farming, animal welfare, or outdoor hardware operating unattended on live animals.

Culture & Benefits

• Work on technology intended to transform grazing and improve farm sustainability.
• Office-first, high-trust culture focused on in-person collaboration, learning, and strong working relationships.
• Health insurance through Southern Cross, wellness leave, and unlimited paid annual leave.
• Six months of fully paid primary caregiver leave and four weeks of fully paid secondary caregiver leave.
• Annual $1,000 personal development budget, snacks and drinks, salary and benefits package, and employee stock ownership plan.
