About the role

We’re changing the way the world farms - and with that comes a responsibility to the producers worldwide who trust us with their animals. Halter collars aren’t serviced, aren’t repairable and need to last 6-10 years, anywhere across the globe. We can’t wait a decade to find out whether a design will survive - so we have to know before it ships. That’s the job of our Reliability team.

As a Reliability Engineer, you’ll be the person who turns “it needs to last” into evidence. You’ll own reliability for products and subsystems through development: assessing risk early, designing accelerated tests grounded in physics of failure, building the models that link hours in a chamber to years on a cow, and making a clear, evidence-backed call on whether a design is ready. You’ll close the loop with the field, comparing what fails out there with what our testing predicted, and changing our tests where they missed.

What you’ll do

• Own the reliability plan for a product or major subsystem through development - turning reliability goals into measurable requirements, test plans and acceptance criteria

• Lead risk assessments, including failure mode and effects analysis and fault tree analysis, and review designs for robustness alongside mechanical, electrical and firmware engineers

• Design and run accelerated tests, including highly accelerated life testing and accelerated life testing, built from first principles and physics of failure, with clear learning goals and decision criteria

• Build reliability and acceleration models that link test time to field life, and write scripts and tools to automate repeated data analysis

• Correlate field failures with test results - show where our testing caught a failure mode, flag where it didn’t, and develop new test methods to replicate the field stresses we’re missing

• Write reliability reports and sign-off recommendations that others can audit, with residual risk and the evidence behind it made clear

• Assess the reliability impact of design, component, production and supplier changes, and work with suppliers on component qualification

• Improve our lab capability - evaluating and introducing new test equipment, fixtures and methods, and scoping and reviewing work from external labs

• Mentor and support junior engineers, reviewing their test setups and data and explaining the reasoning behind our methods

This is a hands-on, first-principles role. We're looking for someone with real experience in reliability or hardware test engineering who wants to go deep on the craft - and who will hold the line on an unwelcome conclusion when the evidence supports it. We’re open on level and will work out the right fit through the interview process, from an experienced individual contributor through to someone ready to set technical direction for the team.

What you’ll bring

• Several years of experience in reliability, test or hardware engineering on electronic or electromechanical products - a degree in electrical, mechanical, mechatronics or materials engineering, or similar, is preferred

• Hands-on experience designing and running reliability tests, such as accelerated life testing, highly accelerated life testing, or environmental and mechanical stress testing

• A solid understanding of how electronic products fail - for example solder joint fatigue, corrosion, moisture ingress, battery degradation and connector wear - and the physics that drives them

• Confidence with reliability statistics and modelling, such as life data analysis, acceleration models, confidence levels and sample sizing

• A first-principles mindset - you want to understand why a test represents the field, not just that it follows a standard

• Clear, honest communication grounded in evidence. You can explain risk and uncertainty to people outside your discipline, and you’ll hold your ground on an unwelcome conclusion when the data backs it

• Strong sense of ownership and a bias for action - you see what needs doing and get on with it without waiting to be asked

• A tenacious curiosity to figure things out, and the process discipline to do it properly every time

• Low ego, highly collaborative and willing to play for the front of the Jersey.

Why our team loves working at Halter:

• Work that genuinely matters. Every now and again a company comes along that transforms an entire industry and leaves the world in a better place. Our team gets to be part of something truly meaningful, helping farmers improve their livelihoods, spend more time with their families, and build more sustainable operations.
