About Sention

Sention Technologies is transforming diagnostics for the battery industry, enabling



unprecedented insights into battery performance, quality, and safety. Our proprietary



technologies allow us to see inside batteries and deliver actionable data to customers



through our software platform. Our solutions empower R&D departments, battery



manufacturers, and pack integrators to meet the demands of the energy transition.

Role Summary

Hands-on role responsible for building, assembling, wiring, calibrating and testing electro-



mechanical devices. The technician will work on both production systems and prototypes



integrating mechanical components, motion systems and electronics to deliver fully



functional validated machines.



You will work at the interface between R&D prototypes and repeatable production,



helping transform experimental hardware into robust, buildable systems. The role requires



comfort with changing requirements and the ability to apply strong practical judgement as



designs evolve. You will build complete systems, debug them, improve how they are built,



and feed practical insight back to engineers.

Key Responsibilities

Electro-Mechanical Assembly

Assemble complete electro-mechanical systems, including frames, motion


systems, sensors, and enclosures


Build and route custom wiring looms (power, signal, comms), including soldering


and connector termination


Integrate electronics, sensors, actuators, and motion components

Produce small batches of custom components using in-house 3D printing

Test, Calibration & Debuging

Calibrate sensors and sub-systems to defined procedures

Diagnose electrical, mechanical, and system-level faults during assembly and


testing


Maintain accurate build documentation and provide feedback for process


improvements


Ensure quality, safety and reliability standards are met in all assembled devices

Production & Process Improvement

Improve build methods, wiring layouts, and assembly sequencing

Reduce build time and variability through practical improvements

Contribute to build documentation, checklists, and test procedures

Collaboration with R&D

Work closely with engineers to feedback build and reliability issues

Support prototype iteration and early production builds

Assist with installation, commissioning, or refurbishment of systems as required

Background & Experience

We are deliberately open on background, but successful applicants must have strong



hands-on competence.

Ideal Educational Backgrounds

HND / HNC / Foundation Degree in:o

Mechatronics

o Electro-Mechanical Engineering



o Mechanical Engineering (with electronics content)



o Instrumentation & Control


Apprenticeship route (strong signal):


o Engineering Technician / Mechatronics / Manufacturing / Automation



o Typically followed by several years of industry experience

Relevant Industry Experience

The following industries are strongly aligned with the role:

Scientific or diagnostic instruments

Automation or motion-control systems

Robotics or gantries

Precision machinery

Semiconductor tools

R&D labs with physical hardware

Experience Level

Strong applications look like:

2-5 years total experience

Background via apprenticeship, HND/HNC, or hands-on engineering degree

Experience building complete machines or complex sub-systems

Ability to clearly explain:


o Why a sensor is noisy



o Why repeatability degrades



o What changes improved build time or reliability

Personal Qualities

Attitudes and personality matter as much as skills for this role:

Methodical, but adaptable

Calm when working with evolving designs

Takes pride in neat, organised wiring

Notices small repeatability or alignment issues

Communicates problems early and clearly

Who You Are

Hands-on and practical: you enjoy building and fixing in particular

Detail-oriented: precision matters to you

Comfortable working with early-stage hardware

Collaborative: you work naturally with engineers and scientists

Pragmatic: you solve problems in a proactive way

Hiring process

We plan to fill this position by January 2026.
