Engineering Manager Performance Modelling

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

As Engineering Manager, Performance Modelling, you will lead a high-impact team of 6 engineers responsible for defining the architecture specifications across generations and validating it through roofline, functional, cycle-accurate, and power modelling. You will partner closely with compiler, ASIC, product, and business development teams to ensure your team's decisions on current and future architectures successfully balance customer needs with software/hardware feasibility, and deliver timelines.

We are looking for an experienced engineering manager to lead an outstanding team of engineers to deliver direct customer and business outcomes. You bring deep technical judgment and a track record of building healthy teams that execute decisively at pace with tight cross-functional collaboration across disciplines.

• Partner closely with ASIC, and compiler teams to define OLIX’s architecture specifications and validate them through performance models across DX-1 generations.

• Build a healthy, high-performance culture that balances innovation, speed, and operational excellence.

• Establish a culture of technical excellence, establishing strong design review practices, clear technical ownership, and predictable execution in a fast-moving hardware/software co-design environment.

• Guide technical decision making to ensure long-term sustainability is balanced with short-term deliveries.

Skills & Experience

• Proven engineering leadership delivering complex long-term projects in ambiguous, fast-moving with direct accountability for the team's execution.

• Deep technical experience with roofline, functional, and cycle-accurate (System C) models for dataflow architectures, with experience driving PPA trade-off discussions across compiler and ASIC teams.

• People leader who coaches, develops, and empowers engineers and managers alike to perform at their best.

Compensation & Equity

• Competitive Salary: £208,000+, commensurate with your experience, skills, and location.
