Job 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 looking for a Financial Controller to help build and run the control, reporting, and accounting engine at OLIX during one of our most critical periods of growth. Reporting to the CFO and working alongside senior leadership, you'll be hands‑on at the core of how we account for everything from production and capital to share options, payroll, and day‑to‑day operations. You'll be one of the people who makes sure the numbers are right, the controls are real, and the company always knows where it stands.

This is an early, formative hire into a finance team we're building from the ground up. You won't be running a mature machine; you'll be helping stand one up: owning a clean month‑end close, producing reliable management and statutory numbers, supporting the selection and rollout of our ERP, and putting real financial controls in place as we scale toward public‑company standard. You'll take on meaningful ownership from day one and grow your remit quickly as the company and the team grow.

The defining challenge is manufacturing. As we scale from prototype toward high‑volume production, you'll help account for a physical supply chain, working closely with the engineering and manufacturing teams building much of the production system themselves, and make sure it's controlled, reconciled, and auditable. This isn't SaaS accounting; it's the harder, more interesting problem of putting rigorous financial control around a fast‑moving hardware business.

You'll work closely with colleagues across finance, including our supply‑chain finance specialist, and take on handover of existing processes as the team scales.

Responsibilities

• Own the day‑to‑day running of financial operations (AP), month‑end close, reconciliations, and the management and statutory reporting that keep the business in control as it scales.

• Prepare accurate, reliable numbers across the business - covering all production activities, accounts payable, payroll, capital, share options, transfer pricing, taxes, and more.

• Support the selection, implementation, and running of our core finance systems (ERP and supporting tooling), helping build lightweight, fit‑for‑purpose processes.

• Help establish audit‑ready controls and processes from the ground up, and lead our external audit.

• Partner with our engineering and manufacturing teams to ensure production data flows through cleanly into accounting, controlled, and is both reportable.

• Provide the clean, reliable data foundation that the FP&A and commercial side of finance depends on.

• Take on broader ownership over time as the finance function, and your remit, grow.
  

Skills & Experience

• Qualified accountant (ACA / ACCA / CIMA or equivalent), ideally trained at a Big Four, now looking for a hands‑on role in a fast‑scaling business.

• High horsepower and high energy: sharp, quick to learn, and able to reason to the right answer from first principles rather than lean on an established playbook. For us, attitude and raw ability matter more than years spent in one niche.

• Strong technical accounting foundations and a high bar for accuracy and control.

• Comfortable being hands‑on in a small, flat team, owning your work end to end with limited support and infrastructure around you.

• Fluent in today’s relevant accounting standards (IFRS / UK GAAP), and keen to learn more. We will be a global company with operations in many countries.

• Keen to build: you want to help stand up a finance function and grow with it, not run a mature one on autopilot.
  

Nice to have

• Exposure to a manufacturing operation or physical supply chain. This matters more to us than chip‑or hardware‑specific knowledge, which you can pick up here.

• Scale‑up experience: you've seen a business grow quickly and know what "good" looks like without needing a big‑company process.

• Working awareness of US GAAP given our US production footprint (useful, not essential).

• Experience supporting an ERP implementation, or standing up finance processes from scratch.

• Semiconductor, hardware, automotive, or advanced‑manufacturing background (Tesla, SpaceX, chip manufacturers, or similar are a plus).
  

Compensation & Equity

• Competitive 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

• Proximity Bonus: We value your time. To minimise your commute and maximise your life, we offer an annual Living‑Local Bonus if your residence is within 20 minutes of the office

• Retirement Benefits: Employer‑contributed retirement plans to help you build long‑term financial security
