Supports technical submissions, approvals, commissioning, and client presentations while standardizing solutions globally. Provides technical leadership and mentoring, and contributes to innovative cooling technologies for mission-critical infrastructure.

The System Design Engineer will design and configure audio-visual systems, collaborate with sales and project teams, and manage technical documentation and quality processes.

Design, characterize, test, qualify, and support production of MEMS timing devices and resonators. Perform simulations, laboratory evaluations, debugging, data analysis, and root-cause investigations. Develop test software and automation, collaborate with MEMS, ASIC, fabrication, assembly, quality, and product engineering teams, and communicate technical findings and project status throughout the product lifecycle.

Lead technical development of custom AHUs, data centre cooling, CRAH, fan wall, and CDU systems. Act as customer technical interface, translate requirements into manufacturable designs, perform coil/fan/pump selections, oversee prototype validation, approve designs, mentor engineers, and ensure cross‑functional delivery from concept to production.

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.

Design and implement user-facing interfaces and UX from concept to production. Build and iterate features to drive engagement and conversion, collaborate with product/marketing/support, participate in code reviews, and maintain high-quality design and deployment workflows.

Design and implement user-facing features from concept through implementation, combining UX design and front-end engineering. Build, iterate, and maintain UI/UX and business logic to drive engagement and conversion, collaborate with product/marketing/support, participate in code reviews, and leverage modern tools and deployment workflows.

Define and drive UX strategy for Canonical's cloud networking products. Design interfaces and prototypes (GUI and terminal) for complex networking concepts, create scalable design systems, conduct user research with DevOps/SRE/network teams, mentor designers, and own cross-product working groups to improve network troubleshooting, observability, and configuration experiences at scale.

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.

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.

Design and develop electrical systems for large-scale liquid cooling, CDU, and mission-critical HVAC equipment. Create schematics, single-line diagrams, panel layouts, and perform electrical calculations. Collaborate with multidisciplinary teams, support manufacturing and commissioning, prepare submittals, mentor junior staff, and ensure compliance with codes and customer requirements.

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.

Build polished, accessible MetaMask interfaces across mobile and browser extension platforms using React and React Native. Implement animations, haptics, and micro-interactions; translate Figma designs into production components; prototype and test with users; develop design-to-code tooling and agentic workflows; and expand the reusable MetaMask design system. Collaborate independently with designers, engineers, and product managers on consumer products serving millions of users.

Lead and deliver civil design workstreams for roads and active travel projects across feasibility to detailed design. Coordinate multidisciplinary teams, collaborate with CAD/BIM staff, mentor junior engineers, support project managers, apply sustainable design principles, and ensure high-quality, technically sound deliverables.
