Top Design Engineer Jobs in Belfast

Design and develop new and modified recycling machinery, create engineered and plant-based solutions, follow group engineering/QMS standards (QFD, FMEA, DFM), reduce manufacturing cost via improved design, support prototype development, field testing and customer complaint resolution, and apply mechanical, electrical and hydraulic knowledge to ensure safety and performance.

Design, develop, test, and optimize electro-mechanical products for energy and renewables applications. Responsibilities include producing engineering drawings, specifications, test plans, and bills of materials; applying DFM/DFA principles; supporting PLM and CAD integration; coordinating with suppliers and cross-functional teams; conducting design reviews and testing; and mentoring junior engineers.

Design and develop new vegetation and tree care equipment, modify existing products, and ensure safety, reliability, performance, and compliance. Apply QFD, FMEA, design-for-manufacture, prototyping, and field testing standards. Collaborate with production, purchasing, suppliers, aftersales, and helpdesk teams to reduce costs, resolve customer complaints, answer technical queries, and evaluate emerging component and competitor design trends.

Build and maintain frontend-leaning, full-stack Creative and Studio products using React and Next.js. Develop AI interfaces, UX/UI workflows, proof-of-concept products, integrations, and end-to-end features. Collaborate with Design, Engineering, Growth, and Sales; iterate based on user feedback; maintain scalable, secure infrastructure; process large datasets; and mentor less experienced engineers. The role emphasizes strong portfolio work and demonstrated software engineering ability rather than formal degrees or certifications.

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 Mobile UI/Design Engineer will enhance the Kraken app's UI with fluid, gesture-driven interactions in React Native, optimizing for performance and mentoring other engineers.

The AV/RF Design Engineer will develop RF/AV system designs, provide technical support, troubleshooting, and documentation, ensuring optimal system performance and collaborating on architecture planning.

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.

Lead design engineering across DuckDuckGo products, combining product design expertise with hands-on coding to prototype, specify, and ensure high-quality implementation. Collaborate closely with engineers, shape design systems, improve workflows, conduct research and experimentation, and autonomously deliver impactful projects for millions of users. Help establish and grow the company’s design engineering discipline while advancing privacy-focused product experiences.

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.

Design and implement user-facing features by combining high-quality visual design and frontend engineering. Improve and expand the design system, build flexible components, collaborate with Product Engineers, ship to users quickly, iterate from feedback, and support customer-facing issues. Work spans wireframing, UI implementation, and end-to-end technical delivery.

Design and implement polished UI/UX at scale, improve and extend the design system, collaborate with product engineers, ship end-to-end features, iterate with user feedback, and consult on bespoke design work while balancing visual design and engineering responsibilities.

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.

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.

The Staff Engineer leads analog and mixed-signal block design, conducts design reviews, mentors junior engineers, and develops methodologies for advanced technology applications.
