Description
About OLIX
AI is growing faster than any technology in history and the explosion in demand has created a massive infrastructure gap; we can no longer build chips or power stations fast enough to keep up. The industry is still leaning on a ten-year-old hardware blueprint that has reached its limit. A new paradigm that is faster and more efficient will be the biggest economic opportunity of the next century and create the most important company of the next decade. The OLIX Decode Accelerator 1 (DX-1) is the first accelerator architected specifically for decode. Rack-scale co-design of logic, data movement, packaging, optics and interconnect enables a step change in system level performance.
The Role
We’re searching for a Staff Performance Modelling Engineer to create and own the analytical and simulation models that steer our architecture and software evolution. You will build functional simulators as well as high-fidelity, cycle-accurate models of our compute system. This role is critical to explore “what-if” design spaces, and deliver insights that directly influence our software, hardware, and optical roadmaps. This role sits at the crossroads of hardware architecture, software tooling and machine-learning workload analysis, perfect for an engineer who loves data-driven decision-making and fast iteration.

Responsibilities
- Project Ownership: Own and deliver projects on your team's roadmap that unlock key high-impact technical and business milestones that drive the success of OLIX.
- Collaboration: Work shoulder-to-shoulder with hardware, compiler and ML framework teams to ensure models reflect reality and reality meets performance goals.
- Functional Simulator: Design, build, and maintain a functional simulator of the DX-1 subsystem and full pipeline.
- Performance Simulator: Design and maintain architectural & cycle-accurate models of the subsystems and pipeline. Identify throughput, latency and utilisation hot-spots; propose architectural, or scheduling fixes.
- 7+ years building performance or power models for CPUs, GPUs, ASICs, or accelerators.
- Proven track record providing technical leadership to a team of 5~10 engineers, resulting in significant business impact.
- Strong coding ability in C++ and Python; experience with discrete-event or cycle-accurate simulators (e.g., gem5, SystemC, custom in-house).
- Strong grasp of computer-architecture fundamentals: memory systems, interconnects, queuing theory, Amdahl/Gustafson analysis.
- Familiarity with machine-learning workloads and common frameworks (PyTorch, TensorFlow, JAX).
- Comfort reading RTL or schematics and discussing micro-architectural trade-offs with hardware designers.
- Excellent data-visualisation and communication skills: able to turn millions of simulation samples into one decisive slide.
- Bachelor’s in EE, CS, Physics, Applied Maths or related; advanced degree preferred but not required.
- Personal or open-source projects in simulators, ML kernels, or performance analysis are a significant plus.
- Competitive Salary: £306,000+ annual salary, commensurate with your experience, skills, and location.
- Equity & Ownership: Meaningful stock options. You’re not just joining the mission; you’re owning a piece of it.
- Premium Healthcare: Comprehensive BUPA medical and dental cover, including Medical History Disregarded (MHD), for complete peace of mind.
- Time Off: 25 days of annual leave, plus all UK bank holidays.
- Elite Hardware: M4 Macs come as standard, with M4 Pro upgrades for our engineering team. We will provide whatever you need to do your best work.
- Optimal Environment: High-spec noise-cancelling headphones and a fully ergonomic workstation designed for deep focus.
- Rapid Prototyping: Access to our high-performance 3D printing lab for work, experimentation, and personal creative projects.
- Chef-prepared meals: if you need to work late.
- Caffeine on Us: We’ve got you covered with a tab at our favourite local coffee shop.
- Visa Sponsorship: We hire the best in the world. We offer full UK and international visa sponsorship.
- Seamless Relocation: Whether you’re moving across the country or across the globe, our dedicated relocation partner provides funding and concierge support to get you settled.
