Job description

Be visionary

Teledyne Technologies Incorporated provides enabling technologies for industrial growth markets that require advanced technology and high reliability. These markets include aerospace and defense, factory automation, air and water quality environmental monitoring, electronics design and development, oceanographic research, deepwater oil and gas exploration and production, medical imaging and pharmaceutical research.

We are looking for individuals who thrive on making an impact and want the excitement of being on a team that wins.

Job Description

This opportunity sits within the Mechanical Engineering team, in the Chelmsford Space Imaging business unit of Teledyne. Space science is at the core of understanding the Universe's origins and future. The sensor device technology includes Charge Coupled Devices (CCDs), CMOS image detectors (visible and infra‑red) and their associated Read Out ICs (ROICs). From the earliest signs of the Big Bang to the effects of solar activity on the Earth, the detailed scientific information and images obtained with Teledyne Space Imaging’s CCD and CMOS sensors are helping us understand more about our surroundings. The imaging sensors developed and tested at the Chelmsford site have been used on humanity’s most important space imaging missions. These include the Hubble Telescope, Kepler, GAIA, Mars Rovers, New Horizons, and Rosetta to name but a few.

Position Summary and Responsibilities

We are seeking a highly skilled Mechanical Engineer to join our dynamic team, where you will lead the design, development, and implementation of mechanical systems and components for a variety of projects. This position is open to all levels of experience. Working closely with cross‑functional teams, you will ensure the successful delivery of high‑quality products and projects by developing bespoke solutions for space imaging sensors, test cameras and front‑end electronics. Your responsibilities will encompass the design of associated assembly and test jigging, as well as transport packaging, and will require you to drive new design solutions from concept through to detailed manufacturing drawings, including the selection of suitable materials.

In collaboration with the Mechanical Engineering Team Leader, Process Engineers, Project Lead Engineers, and Project Managers, you will help guarantee that relevant requirements are met while supporting the development and improvement of assembly jigs and processes used on standard products. Adaptability, efficiency, and advanced competence in CAD are essential, as is a strong focus on design for manufacture, assembly, cost, and lead times to ensure practical and innovative engineering solutions.

Key Responsibilities

• Lead mechanical engineering development activities across projects/programmes by translating customer specifications into suitable designs, driving the design and procurement process, and delivering robust, high‑quality solutions that meet customer expectations efficiently and on schedule.
• Develop and maintain detailed documentation—including design specifications, test plans, manufacturing drawings, and reports—and ensure effective communication of technical information to both internal and external parties through drawings, reports, and presentations.
• Participate actively in design reviews, provide constructive feedback to improve designs, and work closely with process engineers to offer well‑documented solutions to complex technical issues.
• Identify and resolve technical problems during the design phase, proactively assess risks, and demonstrate the ability to work independently to deliver robust solutions.
• Stay up‑to‑date with advancements in mechanical engineering technologies, drive the development of processing expertise, and support the industrialisation of processes for custom product solutions.

Qualifications and Experience

• Mechanical Engineering degree
• Proficiency in CAD software
• Demonstrated ability to interpret FEA results and apply insights to refine and enhance design solutions.
• Ability to design solutions that effectively address challenging environmental conditions, including shock, vibration, and heat transfer, through the application of specialised engineering knowledge.
