Jobs at Fuse Energy

Design, deploy, and operate lossless RDMA-capable leaf-spine fabrics for multi-tenant GPU clusters. Automate provisioning, build telemetry/observability, troubleshoot end-to-end performance, manage out-of-band and office networks, support tenant onboarding, and document designs while upskilling colleagues.

Own end-to-end frontend features for consumer and internal products using React, TypeScript and Next.js. Ship polished, performant UIs, collaborate with backend, mobile, product and design, prototype AI-driven ideas, and help shape product direction for clean energy offerings.

As a Finance Intern, you will support finance projects including M&A, fundraising, and commercial agreements, while developing financial models for strategic decisions.

Define and build Fuse's inference-serving architecture and stack, including request routing, batching, scheduling, and autoscaling for latency-sensitive workloads. Own model-level optimizations (quantisation, distillation, speculative decoding), translate performance SLAs into capacity plans, and integrate low-level GPU/CUDA performance work with serving infrastructure. Set benchmarks, tooling, and act as technical owner of inference performance and reliability.

Design, implement, and optimize low-level CUDA kernels for transformer inference. Profile and eliminate GPU bottlenecks, apply kernel fusion, optimize memory access and mixed-precision kernels, build caching for autoregressive decoding, benchmark performance, and maintain CUDA libraries and tests.

The Operations Analyst at Fuse will optimize supply operations, manage product design, expand to new markets, and negotiate contracts. Ideal candidates are analytical, communicative, and can work independently or collaboratively.

Own day-to-day IT across London offices and cloud: administer SaaS apps, automate tasks with AI, provide 2nd-line support, manage laptops/AV/printers, and assist onboarding/offboarding. Collaborate with IT and engineering to operate and scale the environment.

Develop and optimize CUDA kernels and GPU-accelerated software for latency-sensitive, high-throughput workloads. Profile and tune GPU performance, scale multi-GPU/multi-node systems, build tooling to correlate GPU utilization with real-time energy/grid signals, collaborate with infrastructure and ML teams, and contribute to libraries and best practices for GPU performance in data center environments.

Manage day-to-day office operations, serving as the main contact for landlords and suppliers, while improving processes and providing administrative support.

Lead identification, assessment, acquisition and permitting of renewable energy projects (solar, wind, BESS, hydrogen) across the UK. Develop stakeholder networks, negotiate commercial agreements (NDAs, LOIs, PPAs), coordinate feasibility, permitting and due diligence with finance, GIS and engineering teams, and transition projects into delivery.

Own and optimize the workplace to maximize employee productivity. Manage day-to-day office operations, vendor and landlord relationships, workplace services (connectivity, F&B, office tech, health initiatives), improve processes and remove friction, and provide operational support including meetings, travel, and internal events coordination.

The Customer Support Specialist will be the primary contact for customers, providing excellent support, resolving issues, and offering energy-saving advice, working in shifts including overnight. The role involves collaborative work to enhance customer experience.

Design, build, and scale IoT hardware for the Energy Network, ensuring secure connectivity, device security, and integration with cloud services.

The Senior Recruiter will develop sourcing strategies, screen candidates, manage recruitment processes, and maintain relationships with hiring managers to scale operations and GTM functions.

Develop and implement quantitative models for hedging strategies, analyze market data, and monitor power markets to optimize performance and inform trading decisions.

Build and maintain iOS and Android apps, own features end-to-end, implement high-quality UI/UX, ship consumer-facing AI (including on-device ML) to production, integrate REST APIs, troubleshoot production issues, and contribute to mobile architecture.

Lead UK domestic renewable installation operations, manage and mentor field engineers, act as technical authority for complex escalations, ensure MCS and UK regulatory compliance, implement QA frameworks and training, oversee installations and commissioning across solar, EV chargers, heat pumps and battery systems, and own accreditation and installer network processes.

Create, write, and post original and founder-shaped content for X and LinkedIn. Ideate written angles, brief creative assets, own engagement, and translate founders' and team thinking into compelling posts that build Fuse's written voice.

Be an on-camera Creator producing short-form video and carousels: originate hooks and concepts, shoot and edit quickly when needed, brief and collaborate with videographers, editors and designers, manage community comments and DMs, and build a distinct point of view and audience for Fuse.

Lead the creative and visual vision for brand campaigns and produced content. Develop concepts and storytelling, direct shoots (casting, talent, look, props), run customer testimonials end-to-end, coordinate campaign launches with product and operations, brief social strategists, and carry concepts from idea to final frame alongside a producer.
