Produce temporary works designs for excavation support, propping, formwork and falsework; check drawings to BS5975:2019; attend client meetings and site visits; review sales briefs; manage workload and contribute to continuous improvement.

Build production-quality, pixel-accurate UI components and interactions in React Native; prototype in Figma with designers; own the design system and component library; improve performance, animations, and cross-platform UI architecture; define design-to-dev tooling and collaborate across design and engineering.

The Principal Design Engineer will shape AI-powered product experiences, lead design discussions, collaborate with teams, and mentor designers while advancing the design system.

Lead design and delivery of HV/EHV substations (11kV–400kV) for transmission, distribution and renewables. Client liaison, produce primary substation design deliverables, coordinate multidiscipline teams, apply National Grid/DNO/IEC standards, prepare equipment specifications, manage H&S and CDM design duties, support bids and project delivery to budget, time and quality.

The Design Engineer will craft user-friendly interfaces, prototype designs, collaborate with engineers, and maintain design consistency. They should have a strong background in software product design and familiarity with front-end technologies.

The Senior Mechanical Design Engineer will design energy systems, lead engineering teams, conduct energy audits, and drive technical and commercial innovations.

Lead HV cable system design for 11kV–400kV projects: produce and check calculations, drawings and reports; manage deliverables and a small team; coordinate with CAD and multi-disciplinary engineers; act as client-facing technical lead and support bids.

Owns product development end to end by researching user problems, defining solutions, designing interfaces and prototypes in Figma, building production-ready React experiences, and iterating based on user behavior. The role combines product management, UX and visual design, and frontend engineering while improving workflows, component quality, responsiveness, accessibility of interactions, and design consistency.

This role involves designing, testing, and deploying hardware as part of an Ultra Low Latency team. You’ll own the physical design flow while also understanding RTL and contributing across the chip design process.

Senior mechanical design engineer responsible for 3D mechanical design of rugged plastic and metal products, leading design work with electronics and sensor teams, designing and executing field tests, and developing products for harsh environments in the energy/surveying sectors.

Lead mechanical design of seismic equipment and new products, collaborate with electronics and sensors teams, design and run field tests and interpret results. Apply plastics and metals expertise and represent technical competence to clients.

Lead frontend design and engineering for landing pages and web experiences. Implement performant, accessible React/TypeScript interactions, partner with designers and marketing, build reusable components, and push web capabilities (animations, micro-interactions, WebGL) to elevate brand and product presentation.

Lead automation design across EMEA from concept to delivery: develop secure, scalable SCADA/PLC architectures, design OT networks, ensure IEC62443 alignment, review designs, troubleshoot live sites, produce technical documentation, and develop/test PLC and SCADA code libraries.

The Senior Logical Design Engineer will develop and implement high-performance RTL designs, collaborating with cross-functional teams, ensuring compliance with documentation and standards.

Lead earthing design studies and measurements for substations (up to 400 kV) including EMF calculations, EMI studies and lightning protection. Manage multiple projects, produce proposals, liaise with substation design teams, mitigate risks, and mentor junior engineers. Travel across the UK and overseas for site visits.

The Senior Mechanical Engineer will lead the design and development of mechanical systems for building services, oversee project execution, and provide technical guidance while promoting sustainability and efficiency.

Responsible for implementing complex IC physical designs, collaborating with teams to optimize performance, power, and area while ensuring design integrity and manufacturability.

As a Design Engineer, you will bridge design and engineering, creating user experiences, maintaining a design system using Figma and code, collaborating closely to implement features, and ensuring consistency across platforms.

Lead the design and development of high-speed analog ICs, manage chip subsystems, innovate circuit designs, mentor junior engineers, and communicate technical concepts effectively.

Manage and coordinate design interfaces between contractor systems and other HS2 contractors and the client. Maintain Interface Control Documents, implement interface management plans, support RAM, system safety, interoperability, and security processes, coordinate supply chain and delivery, chair integration meetings, and provide technical input during design, construction and handover.

Design and simulate transistor-level analog/mixed-signal IC blocks (amplifiers, converters, power circuits), define architectures, integrate blocks into mixed-signal systems, present results to teams/customers, support layout, lab evaluation and test, mentor others, and improve design methodologies to meet power, timing and functional objectives.

Design, program, commission, and operate enterprise AV systems for new office builds, retrofits, and events across EMEA. Create AV schematics and documentation, lead deployments, coordinate with architects/contractors, manage vendors and integrators, develop automation for reliability, and support event production and global AV operations to deliver scalable, secure collaboration experiences.

As a Design System Engineer, you'll enhance product quality and consistency by managing the design system, co-developing components, and bridging design and engineering efforts to support AI-driven development.

Provide technical leadership for polymer component design and analysis, interfacing with customers and cross-functional teams. Lead design proposals, generate/approve drawings and test/validation plans, perform failure analysis, support material disposition and continuous improvement, mentor junior engineers, and represent the company in technical meetings and presentations.
