Calibration & Applications Engineer
AG Instruments Ltd | Royal Leamington Spa
About AG Instruments
AG Instruments is a specialist engineering company designing, manufacturing and supplying high-precision gas analysers for medical gas and other power applications. Our analysers are used by customers around the world where accurate, reliable gas measurement is critical.
We work with infrared and other advanced gas-analysis technologies to develop innovative instruments that meet demanding technical and regulatory requirements.
As a growing engineering business, we are continually developing our products, improving manufacturing and calibration methods, and adapting our technology to meet changing customer and market requirements.
We are looking for an Calibration & Applications Engineer to join our team and take responsibility for the calibration, testing and technical support of our gas analysers, alongside a range of wider engineering and customer-facing activities.

The Role
The primary responsibility of this role is the accurate calibration and testing of gas analysers.
Working closely with our CTO, you will be responsible for taking analysers through the calibration process from start to finish, interpreting the results, identifying and resolving problems, completing the required documentation and ensuring each instrument meets the required specification before it leaves the business.
This is a hands-on technical role that requires exceptional attention to detail, concentration and accuracy, combined with the ability to work independently and take ownership of tasks.
You will be trained in AG Instruments' calibration processes and equipment, but we are looking for someone who can progressively develop the knowledge and confidence to manage calibrations independently, rather than relying on constant supervision.
The role will also involve R&D and product development work, as well as having some involvement working across assembly, testing, quality, customer support and supplier management, making this a varied position within a highly technical environment.
Key Responsibilities
Calibration & Testing (Core Responsibility)
- Independently calibrate gas analysers from initial setup through to final verification, including gas concentration, pressure, temperature, linearisation and compensation.
- Set up and operate calibration equipment, including gas switching/blending systems, mass flow controllers and automated calibration systems.
- Interpret calibration results, investigate out-of-specification results and troubleshoot mechanical, electrical, software and gas supply issues.
- Carry out adjustments, repairs and repeat testing where required to ensure analysers meet specification.
- Complete test documentation, calibration certificates and maintain accurate records.
Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
