About the Role:

We are hiring a full-time research scientist. Depending on your qualifications, the job is loop engineering, AI infrastructure research, or both.

Loop engineering is the design and study of closed-loop flows that automate, optimize, and explore SoC designs. These are AI-assisted hardware/software co-design flows. CHIA, from UC Berkeley, is one example of a framework you may use.

AI infrastructure research is full-stack design and optimization of AI systems from storage devices to the host: how memory-device noise affects AI performance, where the system bottlenecks, and which compute-memory architectures are worth building.

You will own the research questions, methods, and written results.

What you will do:

  • Establish best practices for SoC design automation, optimization, and design-space exploration, and make them the way the team runs design studies.
  • Design and implement co-design loops whose steps run SoC tools, simulators, software builds, physical-design feedback, and AI agents, and whose outputs feed the next iteration.
  • Build those flows with the languages and tools the study needs, including Chisel and XLS, simulators, software builds, and ASIC or FPGA CAD.
  • Measure whether the designs a loop produces are correct, and compare them on power, speed, silicon area, or how well the target workload runs. Record which design was chosen, what the search cost, and enough detail that someone else can rerun the study and see why a run failed.

Research: AI infrastructure:

  • Study AI system design from storage and memory devices through controllers, interconnects, and the host software path used by training and inference.
  • Measure how device noise and non-idealities (read and write noise, variation, retention, disturb, and error rates) affect model quality, tail latency, throughput, and energy.
  • Quantify bottlenecks in capacity, bandwidth, latency, power, and data movement, and state what they imply for architecture.
  • Evaluate compute-memory architectures such as near-memory and in-memory compute, computational storage, and disaggregated memory.

What you bring:

  • Bachelor's, master's, or Ph.D. in electrical engineering, computer engineering, or computer science. A bachelor's degree should include research depth in computer architecture, computer systems, VLSI, or electronic design automation.
  • A record of taking a research question to a measured, written result.
  • Strong in Python.

For a loop-engineering assignment:

  • Experience automating an SoC, RTL, or physical-design flow, including design-space exploration or closed-loop optimization.
  • Ability to design interfaces between design tools so a flow can be reused.

For an AI infrastructure assignment:

  • Research on the path from storage or memory devices to a host running an AI workload, and on how device behavior, system bottlenecks, or compute-memory architecture affect AI performance.

Preferred Qualifications:

  • Hands-on experience with an AI-assisted hardware/software co-design loop framework, such as CHIA, or with another agentic or scripted flow.
  • Proficiency with Chisel, XLS, or RISC-V SoC integration, and with RTL simulation or FPGA prototyping.
  • Experience with commercial ASIC flows, and with reading timing, power, and area reports.
  • Experience with architecture simulators.
  • Background in memory or storage reliability: device noise, ECC, endurance, or error models.
  • Papers or patents in computer architecture, VLSI CAD, or hardware/software co-design.

What success looks like:

In the first year, a loop-engineering hire produces a reusable co-design loop for an SoC decision and a written best practice. An AI infrastructure hire produces a result that ties a bottleneck, a memory-device noise effect, or a compute-memory architecture to host-level AI performance. A hire for both produces both.

About This Role

Research Scientists push the boundaries of what AI can do. They design experiments, develop novel architectures, publish papers, and translate research breakthroughs into production capabilities. This is where the fundamental advances happen, from attention mechanisms to diffusion models to reasoning chains.

The work is intellectually demanding and often ambiguous. You might spend months on an approach that doesn't pan out. The best research scientists combine deep mathematical intuition with engineering pragmatism. They know when to go deep on theory and when to run experiments. They read papers voraciously and can spot incremental contributions from genuine breakthroughs.

Across the 9,079 AI roles we're tracking, Research Scientist positions make up 2% of the market. At SK hynix memory solutions, this role fits into their broader AI and engineering organization.

Research Scientist roles are concentrated at major AI labs (OpenAI, Anthropic, Google DeepMind, Meta FAIR) and well-funded AI startups. The competition is intense. PhD is effectively required for most positions, and publication track record matters. Compensation is among the highest in AI, reflecting both the scarcity of talent and the strategic importance of research breakthroughs.

What the Work Looks Like

A typical week includes: reading and discussing recent papers with your team, designing and running experiments on multi-GPU clusters, analyzing results and iterating on hypotheses, writing up findings for internal review or publication, and collaborating with engineering teams to productionize promising results. The ratio of thinking to coding is higher than in engineering roles.

Skills Required

Python (18% of roles)

PhD strongly preferred for most roles. Deep expertise in a specific area (NLP, computer vision, reinforcement learning, multimodal) is expected. PyTorch is the standard. Publication track record matters. Strong mathematical foundations in linear algebra, probability, optimization, and information theory are assumed.

Beyond the fundamentals, companies value experience with large-scale distributed training, novel architecture design, and the ability to bridge theory and practice. Understanding of current frontier topics (reasoning, multimodal, long-context, alignment) is essential. Code quality matters more than many researchers expect. Labs want researchers who can implement their ideas cleanly.

Strong research postings specify the research area, mention the team you'd join, and describe the problems they're working on. They often list recent publications from the team. Vague 'AI research' postings without specifics usually mean the company wants to sound impressive but doesn't have a real research agenda.

Publish consistently, contribute to open-source projects in your area, and build relationships at conferences. Industry research offers better compensation and compute resources than academia, but the pressure to show product impact is real.

What to Expect in Interviews

Research interviews are multi-stage: a research talk (present your best paper), technical deep-dives on your methodology, and often a 'research proposal' exercise where you design an experiment to test a hypothesis. Coding rounds test implementation ability alongside theoretical knowledge. Be prepared to implement a paper from scratch and discuss the design choices the authors made. Strong candidates can critique papers constructively and identify gaps in experimental methodology.

When evaluating opportunities: Strong research postings specify the research area, mention the team you'd join, and describe the problems they're working on. They often list recent publications from the team. Vague 'AI research' postings without specifics usually mean the company wants to sound impressive but doesn't have a real research agenda.
