Job summary

Cellular Origins is hiring a Senior Mechanical Design Engineer to own the mechanical design of critical modules in our robotic manufacturing platform. You will move concepts from prototype to manufacturable reality, ensuring repeatable, robust performance in demanding environments.

You will collaborate with chemistry, software, robotics and systems teams, applying tolerance analyses and 3D CAD (SolidWorks) to deliver reliable electromechanical products suitable for GMP contexts.

Qualifications

A Mechanical Engineering degree, or a science-based degree with strong, relevant industrial experience.
Hands-on experience designing precision devices across length scales from tens of microns to tens of millimetres.
Proven experience developing complex electromechanical products and delivering them into manufacture.
Proven experience working in cross-functional / cross-disciplinary teams.
Experience leveraging analytical techniques to support design decisions with a focus on tolerance analyses, FEA and motor calculations.
Strong 3D CAD capability, ideally SolidWorks.
Deep knowledge of material selection and manufacturing processes.
Experience improving designs until they are consistently reliable, not simply functional.
Ability to work collaboratively, challenge assumptions and make sound engineering decisions with incomplete information.

Responsibilities

Own the detailed mechanical design of critical modules within our robotic manufacturing platform.
Turn early concepts and prototypes into stable, manufacturable designs that perform consistently.
Build detailed tolerance analyses and use analytical techniques to understand and improve performance.
Make thoughtful decisions around materials, manufacturing methods and component design.
Work hands-on with prototypes and hardware, learning quickly and feeding that back into better designs.
Collaborate with engineers from other disciplines to solve system-level challenges.
Use experience to spot risks early and guide designs from “it works” to “it works all the time”.
Help raise the standard of mechanical design across the team by sharing judgement and methods.

Job description

Cell therapies have the potential to transform how devastating diseases such as cancer are treated. But for more patients to benefit, these therapies need to be manufactured reliably, efficiently and at a scale the industry has not been able to achieve before.

At Cellular Origins, we’re changing that. Our Constellation platform brings robotics and automation into cell therapy manufacturing, helping developers scale their processes without having to redesign the biology or proven equipment behind them. As a Senior Mechanical Design Engineer, you’ll help make that possible by turning complex mechanical challenges into precise, dependable designs that work not just once, but every time.

Job Description

This is an opportunity to take real ownership of some of the most mechanically demanding parts of our robotic manufacturing system.

You’ll get the autonomy to design critical precision modules from concept through to manufacture, using your judgement and experience to move quickly towards solutions that are robust, repeatable and practical to build.

You’ll join an interdisciplinary team spanning mechanical engineering, robotics, software, systems and biology. Your work will sit at the point where precision engineering meets a very human goal: making cell therapies accessible to far more patients.

You’ll bring depth in precision design of complex electromechanical devices and use it to help us build a system that can perform reliably in demanding manufacturing environments.

You’ll get to:

Own the detailed mechanical design of critical modules within our robotic manufacturing platform.
Turn early concepts and prototypes into stable, manufacturable designs that perform consistently.
Build detailed tolerance analyses and use the right analytical techniques to understand and improve performance.
Make thoughtful decisions around materials, manufacturing methods and component design.
Work hands‑on with prototypes and hardware, learning quickly from what you see and feeding that back into better designs.
Collaborate closely with engineers from other disciplines to solve system-level challenges rather than isolated component problems.
Use your experience to spot risks early and guide designs from “it works” to “it works all the time”.
Help raise the standard of mechanical design across the team by sharing your judgement, methods and experience.

Qualifications

Requirements

You’ll thrive here if precision design is something you genuinely enjoy. You notice the details that matter, but you also know when to stop analysing and build something.

You’ll bring a strong engineering foundation alongside hands‑on experience taking products through development and into manufacture.

You’ll also bring:

A Mechanical Engineering degree, or a science‑based degree with strong, relevant industrial experience.
Hands‑on experience designing precision devices across length scales from tens of microns to tens of millimetres.
Proven experience developing complex electromechanical products and delivering them into manufacture.
Proven experience working in cross‑functional / cross‑disciplinary teams.
Experience leveraging analytical techniques to support design decisions with a particular focus on tolerance analyses, FEA and motor calculations.
Strong 3D CAD capability, ideally using SolidWorks.
Deep knowledge of material selection and manufacturing processes.
Experience improving designs until they are consistently reliable, not simply functional.
The ability to work collaboratively, challenge assumptions and make sound engineering decisions with incomplete information.

Desired experience

Experience working in regulated industry with a particular emphasis on design for GMP.
Experience creating appropriate documentation to support release of products for use in regulatory environments.
