## 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 searching for a Software Engineering Intern to join the London team in Summer 2027 building the software stack (compiler, firmware, runtime, simulation and tooling) for our next-generation Accelerator. DX-1 is a dataflow architecture built specifically for decode, deployed in a disaggregated inference environment.

## Responsibilities

- Project Ownership: Own and deliver scoped projects on your team’s roadmap, with a named mentor and a defined outcome by the end of your term.
- Build and Ship: Contribute production code to our compiler, runtime, simulation or developer tooling, to the same standard as the rest of the team.
- Optimize Performance: Apply techniques such as layout, scheduling and tiling, or extend our simulation so that it models real system behaviour more faithfully.
- Partner Across Teams: Work directly with compiler, systems, FPGA and ASIC engineers to understand device trade-offs and where your work fits.
- Measure and Communicate: Ground conclusions in measurement rather than assumption, and report results clearly.

## Skills & Experience

- Working toward a Bachelor’s or Master’s degree in computer science, computer engineering, electrical engineering, mathematics, or a related field, with an available co-op or internship term.
- Practical experience with C/C++ programming beyond coursework.
- Solid systems fundamentals, including memory hierarchies, concurrency, and performance analysis.
- Demonstrated depth in either compilers or systems software.
- Familiarity with ML framework internals, low-level programming, or optimisation techniques.
- Strong problem-solving skills and the ability to think critically and creatively.
- Excellent teamwork and communication skills, with the ability to collaborate effectively with cross-functional teams.

## Compensation

- Competitive salary: commensurate with experience, skills, and location

Due to U.S. export control regulations, candidates’ eligibility to work at OLIX depends on their most recent citizenship or permanent residency status. We are generally unable to consider applicants whose most recent citizenship or permanent residence is in certain restricted countries (currently including Iran, North Korea, Syria, Cuba, Russia, Belarus, China, Hong Kong, Macau, and Venezuela). Applicants who have subsequently obtained citizenship or permanent residency in another country not subject to these restrictions may still be eligible.

## About OLIX

## Company Overview
- **One-liner**: OLIX, formerly known as Flux, is building a new compute paradigm using an SRAM-architecture integrated with photonics to solve the fundamental memory, energy, and speed constraints in deploying frontier AI.
- **Entity Type**: Private, Series A (raised $220M in February 2026)
- **Headquarters**: London, United Kingdom
- **Founded**: 2024
- **Founders**: James Dacombe (CEO)

## Core Business
- **Primary industry/industries**: Semiconductor Manufacturing, AI Infrastructure, Photonic Computing
- **Target customers**: Enterprise AI labs, hyperscalers, and frontier AI model developers requiring high-throughput, low-latency compute
- **Mission or purpose statement**: "Solving the most consequential problem in the deployment of frontier AI" by building infrastructure that overcomes the limits of current GPU-based memory architecture.

## Products & Services
- **OLIX Compute Platform**: A new hardware architecture combining SRAM-based compute with integrated photonics, designed to surpass HBM-based systems on throughput per megawatt and total cost of ownership (TCO), while delivering significantly better interactivity and latency than silicon-only SRAM architectures.

## Market Standing
- **Valuation**: Unicorn status; estimated $1–2.5B (latest round Feb 2026, per Dealroom)
- **Key Metric**: $220M in total funding (Series A, led by Hummingbird Ventures, with participation from Crane Venture Partners and others)
- **Notable Investors/Partners**: Hummingbird Ventures (Series A lead), Crane Venture Partners (pre-seed lead), and 4+ additional investors across seed and Series A rounds.
- **Growth Signals**: Headcount grew 420% YoY to 70 employees; operating in 6 countries (UK, US, Canada, Armenia, Romania, Germany); active job postings surged 188.9% YoY with 26 open roles as of mid-2026.

## Competitive Advantages
- **Unique photonic-SRAM architecture**: A contrarian bet that GPU-based approaches cannot simultaneously deliver high throughput and high interactivity at low cost due to physical design constraints.
- **Talent density**: Heavy hiring from top compute and AI companies (Apple, Amazon, Arm, Google, Tenstorrent).
- **First-mover in inference-era compute**: Targeting a fundamental bottleneck as frontier models require vastly more tokens per inference.

## Strategic Focus
- **Scale teams**: Aggressively hiring across engineering (ASIC/photonic design, FPGA, optics, process integration), operations, and legal in London, Austin, Toronto, Bristol, and San Francisco.
- **Prototype and productize**: Moving from architecture conception into hardware integration and manufacturing (roles include Process Integration Engineer, Opto-Mechanical Engineer, Layout Engineering Manager).
- **Transition from Flux branding**: Rebranded to OLIX in January 2026 to signal a new phase of company identity and scale.

## Why Work Here
- **In-person culture**: OLIX is an in-person company. They incentivize living within a 20-minute commute of the office with a £24,000 annual living-local bonus.
- **Compensation**: Benchmark-leading base salary, meaningful stock options (early employees build significant ownership), and workplace pension.
- **Benefits**: Comprehensive BUPA medical & dental (with Medical History Disregarded), 25 days holiday + UK bank holidays + birthday leave, meals on-site, cycle-to-work scheme, nursery scheme, visa sponsorship and relocation support.
- **Engineering environment**: M4 Mac standard (M5 Pro upgrade for engineering), on-site 3D-printing lab, noise-cancelling headphones, fully ergonomic workstation, and a culture of deep focus.
- **Impact**: "You will work with some of the best minds in photonics, systems, and compute on one of the defining problems of our era."
